(Note that subqueries should be normally created using the :meth:`_expression.Select.alias` method, as many platforms require nested SELECT statements to be named). As expressions are composed together, the application of :meth:`self_group` is automatic - end-user code should never need to use this method directly. Note that SQLAlchemy's clause constructs take operator precedence into account - so parenthesis might not be needed, for example, in an expression like ``x OR (y AND z)`` - AND takes precedence over OR.

The return value is a :class:`~.Compiled` object. Calling ``str()`` or ``unicode()`` on the returned value will yield a string representation of the result. The :class:`~.Compiled` object also can return a dictionary of bind parameter names and values using the ``params`` accessor. :param bind: An ``Engine`` or ``Connection`` from which a ``Compiled`` will be acquired. This argument takes precedence over this :class:`_expression.ClauseElement`'s bound engine, if any. :param column_keys: Used for INSERT and UPDATE statements, a list of column names which should be present in the VALUES clause of the compiled statement. If ``None``, all columns from the target table object are rendered. :param dialect: A ``Dialect`` instance from which a ``Compiled`` will be acquired. This argument takes precedence over the `bind` argument as well as this :class:`_expression.ClauseElement` 's bound engine, if any. :param inline: Used for INSERT statements, for a dialect which does not support inline retrieval of newly generated primary key columns, will force the expression used to create the new primary key value to be rendered inline within the INSERT statement's VALUES clause.

While the most familiar kind of :class:`_expression.ColumnElement` is the :class:`_schema.Column` object, :class:`_expression.ColumnElement` serves as the basis for any unit that may be present in a SQL expression, including the expressions themselves, SQL functions, bound parameters, literal expressions, keywords such as ``NULL``, etc. :class:`_expression.ColumnElement` is the ultimate base class for all such elements. A wide variety of SQLAlchemy Core functions work at the SQL expression level, and are intended to accept instances of :class:`_expression.ColumnElement` as arguments. These functions will typically document that they accept a "SQL expression" as an argument. What this means in terms of SQLAlchemy usually refers to an input which is either already in the form of a :class:`_expression.ColumnElement` object, or a value which can be **coerced** into one. The coercion rules followed by most, but not all, SQLAlchemy Core functions with regards to SQL expressions are as follows: * a literal Python value, such as a string, integer or floating point value, boolean, datetime, ``Decimal`` object, or virtually any other Python object, will be coerced into a "literal bound value". This generally means that a :func:`.bindparam` will be produced featuring the given value embedded into the construct; the resulting :class:`.BindParameter` object is an instance of :class:`_expression.ColumnElement`. The Python value will ultimately be sent to the DBAPI at execution time as a parameterized argument to the ``execute()`` or ``executemany()`` methods, after SQLAlchemy type-specific converters (e.g. those provided by any associated :class:`.TypeEngine` objects) are applied to the value. * any special object value, typically ORM-level constructs, which feature a method called ``__clause_element__()``. The Core expression system looks for this method when an object of otherwise unknown type is passed to a function that is looking to coerce the argument into a :class:`_expression.ColumnElement` expression. The ``__clause_element__()`` method, if present, should return a :class:`_expression.ColumnElement` instance. The primary use of ``__clause_element__()`` within SQLAlchemy is that of class-bound attributes on ORM-mapped classes; a ``User`` class which contains a mapped attribute named ``.name`` will have a method ``User.name.__clause_element__()`` which when invoked returns the :class:`_schema.Column` called ``name`` associated with the mapped table. * The Python ``None`` value is typically interpreted as ``NULL``, which in SQLAlchemy Core produces an instance of :func:`.null`. A :class:`_expression.ColumnElement` provides the ability to generate new :class:`_expression.ColumnElement` objects using Python expressions. This means that Python operators such as ``==``, ``!=`` and ``<`` are overloaded to mimic SQL operations, and allow the instantiation of further :class:`_expression.ColumnElement` instances which are composed from other, more fundamental :class:`_expression.ColumnElement` objects. For example, two :class:`.ColumnClause` objects can be added together with the addition operator ``+`` to produce a :class:`.BinaryExpression`. Both :class:`.ColumnClause` and :class:`.BinaryExpression` are subclasses of :class:`_expression.ColumnElement`:: >>> from sqlalchemy.sql import column >>> column('a') + column('b') >>> print(column('a') + column('b')) a + b .. seealso:: :class:`_schema.Column` :func:`_expression.column` Úcolumn_elementFr…NTcó&—|tjtjtjfvrB|jjtjjur%t|tj tj ¦«S|tjtjfvrt|¦«S|Sr)rr§r«Ú_asboolr*Ú_type_affinityrÚBOOLEANTYPEÚ AsBooleanÚistrueÚisfalseÚany_opÚall_opÚGroupingrs rr’zColumnElement.self_groupÅsp€à œ ¬ µyÔ7HÐIÐIÐIØ” Ô(HÔ,@Ô,OÐOÐOå˜T¥9Ô#3µYÔ5FÑGÔGÐGØ Ô)9Ô+;Ð<Ð <Ð <Ý˜D‘>”>Ð!àˆKrcóÖ•—|jjtjjur%t |t jt j¦«Stt|¦« ¦«Sr)r*rÖrr×rØrrÚrÙÚsuperrLr°©rPrFs €rr°zColumnElement._negateÐsMø€ØŒ9Ô#¥xÔ';Ô'JÐJÐJÝ˜T¥9Ô#4µiÔ6FÑGÔGÐGå¨Ñ-Ô-×5Ò5Ñ7Ô7Ð7rcó—tjSr©rÚNULLTYPErTs rr*zColumnElement.typeÖó€åÔ Ð rcó¸— |jj}||¦«S#t$r6}tjtd|jz¦«|¬¦«Yd}~dSd}~wwxYw)NzOObject %r associated with '.type' attribute is not a TypeEngine class or object©Úreplace_context)r*Úcomparator_factoryÚAttributeErrorrÚraise_r¹)rPrèÚerrs rrMzColumnElement.comparatorÚsŸ€ð ,Ø!%¤Ô!=Ðð&Ð% dÑ+Ô+Ð+øõð ð ð ÝŒKÝð:Ø<@¼IñFñôð!$ð ñ ô ð ð ð ð ð ð ð øøøøð øøøs‚™ A£+AÁAcó— t|j|¦«S#t$r`}tjtdt|¦«j›dt|j¦«j›d|›¦«|¬¦«Yd}~dSd}~wwxYw)NzNeither z object nor z object has an attribute ræ)ÚgetattrrMrérrêr*rÀ)rPr<rës rÚ__getattr__zColumnElement.__getattr__és·€ð Ý˜4œ?¨CÑ0Ô0Ð0øÝð ð ð ÝŒKÝõ˜T™ œ Ô+Ð+Ð+Ý˜Tœ_Ñ-Ô-Ô6Ð6Ð6Ø˜ð ñôð!$ð ñ ô ð ð ð ð ð ð ð øøøøð øøøs‚— B¡AA<Á<Bcó$—||jg|¢Ri|¤ŽSr©rM©rPÚopr‡rvs rÚoperatezColumnElement.operateùs$€Øˆr$”/Ð4 EÐ4Ð4Ð4¨VÐ4Ð4Ð4rcó —|||jfi|¤ŽSrrðrñs rÚreverse_operatezColumnElement.reverse_operateüs€Øˆr%˜œÐ3Ð3¨FÐ3Ð3Ð3rcó6—td||||jd¬¦«S)NT)Ú_compared_to_operatorr%Ú_compared_to_typer5)r7r*©rPr´Úobjr%s rÚ_bind_paramzColumnElement._bind_paramÿs-€ÝØØØ"*ØØ"œiØð ñ ô ð rcó—|S)z^Return a column expression.

The return value is an instance of :class:`.BindParameter`; this is a :class:`_expression.ColumnElement` subclass which represents a so-called "placeholder" value in a SQL expression, the value of which is supplied at the point at which the statement in executed against a database connection. In SQLAlchemy, the :func:`.bindparam` construct has the ability to carry along the actual value that will be ultimately used at expression time. In this way, it serves not just as a "placeholder" for eventual population, but also as a means of representing so-called "unsafe" values which should not be rendered directly in a SQL statement, but rather should be passed along to the :term:`DBAPI` as values which need to be correctly escaped and potentially handled for type-safety. When using :func:`.bindparam` explicitly, the use case is typically one of traditional deferment of parameters; the :func:`.bindparam` construct accepts a name which can then be referred to at execution time:: from sqlalchemy import bindparam stmt = select([users_table]).\ where(users_table.c.name == bindparam('username')) The above statement, when rendered, will produce SQL similar to:: SELECT id, name FROM user WHERE name = :username In order to populate the value of ``:username`` above, the value would typically be applied at execution time to a method like :meth:`_engine.Connection.execute`:: result = connection.execute(stmt, username='wendy') Explicit use of :func:`.bindparam` is also common when producing UPDATE or DELETE statements that are to be invoked multiple times, where the WHERE criterion of the statement is to change on each invocation, such as:: stmt = (users_table.update(). where(user_table.c.name == bindparam('username')). values(fullname=bindparam('fullname')) ) connection.execute( stmt, [{"username": "wendy", "fullname": "Wendy Smith"}, {"username": "jack", "fullname": "Jack Jones"}, ] ) SQLAlchemy's Core expression system makes wide use of :func:`.bindparam` in an implicit sense. It is typical that Python literal values passed to virtually all SQL expression functions are coerced into fixed :func:`.bindparam` constructs. For example, given a comparison operation such as:: expr = users_table.c.name == 'Wendy' The above expression will produce a :class:`.BinaryExpression` construct, where the left side is the :class:`_schema.Column` object representing the ``name`` column, and the right side is a :class:`.BindParameter` representing the literal value:: print(repr(expr.right)) BindParameter('%(4327771088 name)s', 'Wendy', type_=String()) The expression above will render SQL such as:: user.name = :name_1 Where the ``:name_1`` parameter name is an anonymous name. The actual string ``Wendy`` is not in the rendered string, but is carried along where it is later used within statement execution. If we invoke a statement like the following:: stmt = select([users_table]).where(users_table.c.name == 'Wendy') result = connection.execute(stmt) We would see SQL logging output as:: SELECT "user".id, "user".name FROM "user" WHERE "user".name = %(name_1)s {'name_1': 'Wendy'} Above, we see that ``Wendy`` is passed as a parameter to the database, while the placeholder ``:name_1`` is rendered in the appropriate form for the target database, in this case the PostgreSQL database. Similarly, :func:`.bindparam` is invoked automatically when working with :term:`CRUD` statements as far as the "VALUES" portion is concerned. The :func:`_expression.insert` construct produces an ``INSERT`` expression which will, at statement execution time, generate bound placeholders based on the arguments passed, as in:: stmt = users_table.insert() result = connection.execute(stmt, name='Wendy') The above will produce SQL output as:: INSERT INTO "user" (name) VALUES (%(name)s) {'name': 'Wendy'} The :class:`_expression.Insert` construct, at compilation/execution time, rendered a single :func:`.bindparam` mirroring the column name ``name`` as a result of the single ``name`` parameter we passed to the :meth:`_engine.Connection.execute` method. :param key: the key (e.g. the name) for this bind param. Will be used in the generated SQL statement for dialects that use named parameters. This value may be modified when part of a compilation operation, if other :class:`BindParameter` objects exist with the same key, or if its length is too long and truncation is required. :param value: Initial value for this bind param. Will be used at statement execution time as the value for this parameter passed to the DBAPI, if no other value is indicated to the statement execution method for this particular parameter name. Defaults to ``None``. :param callable\_: A callable function that takes the place of "value". The function will be called at statement execution time to determine the ultimate value. Used for scenarios where the actual bind value cannot be determined at the point at which the clause construct is created, but embedded bind values are still desirable. :param type\_: A :class:`.TypeEngine` class or instance representing an optional datatype for this :func:`.bindparam`. If not passed, a type may be determined automatically for the bind, based on the given value; for example, trivial Python types such as ``str``, ``int``, ``bool`` may result in the :class:`.String`, :class:`.Integer` or :class:`.Boolean` types being automatically selected. The type of a :func:`.bindparam` is significant especially in that the type will apply pre-processing to the value before it is passed to the database. For example, a :func:`.bindparam` which refers to a datetime value, and is specified as holding the :class:`.DateTime` type, may apply conversion needed to the value (such as stringification on SQLite) before passing the value to the database. :param unique: if True, the key name of this :class:`.BindParameter` will be modified if another :class:`.BindParameter` of the same name already has been located within the containing expression. This flag is used generally by the internals when producing so-called "anonymous" bound expressions, it isn't generally applicable to explicitly-named :func:`.bindparam` constructs. :param required: If ``True``, a value is required at execution time. If not passed, it defaults to ``True`` if neither :paramref:`.bindparam.value` or :paramref:`.bindparam.callable` were passed. If either of these parameters are present, then :paramref:`.bindparam.required` defaults to ``False``. :param quote: True if this parameter name requires quoting and is not currently known as a SQLAlchemy reserved word; this currently only applies to the Oracle backend, where bound names must sometimes be quoted. :param isoutparam: if True, the parameter should be treated like a stored procedure "OUT" parameter. This applies to backends such as Oracle which support OUT parameters. :param expanding: if True, this parameter will be treated as an "expanding" parameter at execution time; the parameter value is expected to be a sequence, rather than a scalar value, and the string SQL statement will be transformed on a per-execution basis to accommodate the sequence with a variable number of parameter slots passed to the DBAPI. This is to allow statement caching to be used in conjunction with an IN clause. .. seealso:: :meth:`.ColumnOperators.in_` :ref:`baked_in` - with baked queries .. note:: The "expanding" feature does not support "executemany"- style parameter sets. .. versionadded:: 1.2 .. versionchanged:: 1.3 the "expanding" bound parameter feature now supports empty lists. .. seealso:: :ref:`coretutorial_bind_param` :ref:`coretutorial_insert_expressions` :func:`.outparam` Nr0z[% \$]+Ú_Úparamz %%(%d param)s)Ú isinstancerr*r<rÚquoted_namer2rÁÚreÚsubÚstripÚ_identifying_keyÚ _orig_keyr5r8Úcallabler;r|Ú expandingÚcoerce_compared_valuerÚ_resolve_value_to_type)rPr<r8r%r5r|ÚquoteÚ callable_rIr;r÷røs rÚ__init__zBindParameter.__init__Åsš€õDc<Ñ(Ô(ð Ø”HˆEØ”'ˆCØ•vÐÐØ¥Ð<¨9¸Ð+<ˆHØ•Fˆ?ˆ?ØˆEàÐÝ˜c 5Ñ)Ô)ˆCàð KÝ'Øåt‘H”Hàõ”F˜>¨3°Ñ4Ô4×:Ò:¸3Ñ?Ô?Ð?à ð ññôˆDŒHˆHðÐJÕ.¨ÅÀDÁÄÑ/IÑJÔJˆDŒHð !%¤ˆÔð˜ ˆŒàˆŒØˆŒ Ø!ˆŒ Ø$ˆŒØ ˆŒ Ø"ˆŒàˆ=Ø Ð,Ø-×CÒCØ)¨5ñô” õ%Ô;¸EÑBÔB” Ý ˜tÑ $Ô $ð Ø˜™œˆDŒIˆIˆIàˆDŒIˆIˆIrcó<—| ¦«}||_|S)zrReturn a copy of this :class:`.BindParameter` in the context of an expanding IN against a tuple. )rÚ_expanding_in_types)rPÚtypesÚcloneds rÚ_with_expanding_in_typesz&BindParameter._with_expanding_in_typesÛs€ð —’‘”ˆØ%*ˆÔ"Øˆ rcó°—| ¦«}||_d|_d|_|jt jurtj|¦«|_|S)zYReturn a copy of this :class:`.BindParameter` with the given value set.

E.g.:: from sqlalchemy import text t = text("SELECT * FROM users") result = connection.execute(t) The advantages :func:`_expression.text` provides over a plain string are backend-neutral support for bind parameters, per-statement execution options, as well as bind parameter and result-column typing behavior, allowing SQLAlchemy type constructs to play a role when executing a statement that is specified literally. The construct can also be provided with a ``.c`` collection of column elements, allowing it to be embedded in other SQL expression constructs as a subquery. Bind parameters are specified by name, using the format ``:name``. E.g.:: t = text("SELECT * FROM users WHERE id=:user_id") result = connection.execute(t, user_id=12) For SQL statements where a colon is required verbatim, as within an inline string, use a backslash to escape:: t = text("SELECT * FROM users WHERE name='\:username'") The :class:`_expression.TextClause` construct includes methods which can provide information about the bound parameters as well as the column values which would be returned from the textual statement, assuming it's an executable SELECT type of statement. The :meth:`_expression.TextClause.bindparams` method is used to provide bound parameter detail, and :meth:`_expression.TextClause.columns` method allows specification of return columns including names and types:: t = text("SELECT * FROM users WHERE id=:user_id").\ bindparams(user_id=7).\ columns(id=Integer, name=String) for id, name in connection.execute(t): print(id, name) The :func:`_expression.text` construct is used in cases when a literal string SQL fragment is specified as part of a larger query, such as for the WHERE clause of a SELECT statement:: s = select([users.c.id, users.c.name]).where(text("id=:user_id")) result = connection.execute(s, user_id=12) :func:`_expression.text` is also used for the construction of a full, standalone statement using plain text. As such, SQLAlchemy refers to it as an :class:`.Executable` object, and it supports the :meth:`Executable.execution_options` method. For example, a :func:`_expression.text` construct that should be subject to "autocommit" can be set explicitly so using the :paramref:`.Connection.execution_options.autocommit` option:: t = text("EXEC my_procedural_thing()").\ execution_options(autocommit=True) Note that SQLAlchemy's usual "autocommit" behavior applies to :func:`_expression.text` constructs implicitly - that is, statements which begin with a phrase such as ``INSERT``, ``UPDATE``, ``DELETE``, or a variety of other phrases specific to certain backends, will be eligible for autocommit if no transaction is in progress. :param text: the text of the SQL statement to be created. Use ``:`` to specify bind parameters; they will be compiled to their engine-specific format. :param autocommit: whether or not to set the "autocommit" execution option for this :class:`_expression.TextClause` object. :param bind: an optional connection or engine to be used for this text query. :param bindparams: A list of :func:`.bindparam` instances used to provide information about parameters embedded in the statement. E.g.:: stmt = text("SELECT * FROM table WHERE id=:id", bindparams=[bindparam('id', value=5, type_=Integer)]) :param typemap: A dictionary mapping the names of columns represented in the columns clause of a ``SELECT`` statement to type objects. E.g.:: stmt = text("SELECT * FROM table", typemap={'id': Integer, 'name': String}, ) .. seealso:: :ref:`sqlexpression_text` - in the Core tutorial :ref:`orm_tutorial_literal_sql` - in the ORM tutorial )r~N)rmr…)rkrzrÚexecution_options)rPryr~rzr{rmÚstmts rÚ_create_textzTextClause._create_text‚sm€õ\˜$ TÐ*Ñ*Ô*ˆØð 0Ø"4”?

Given a text construct such as:: from sqlalchemy import text stmt = text("SELECT id, name FROM user WHERE name=:name " "AND timestamp=:timestamp") the :meth:`_expression.TextClause.bindparams` method can be used to establish the initial value of ``:name`` and ``:timestamp``, using simple keyword arguments:: stmt = stmt.bindparams(name='jack', timestamp=datetime.datetime(2012, 10, 8, 15, 12, 5)) Where above, new :class:`.BindParameter` objects will be generated with the names ``name`` and ``timestamp``, and values of ``jack`` and ``datetime.datetime(2012, 10, 8, 15, 12, 5)``, respectively. The types will be inferred from the values given, in this case :class:`.String` and :class:`.DateTime`. When specific typing behavior is needed, the positional ``*binds`` argument can be used in which to specify :func:`.bindparam` constructs directly. These constructs must include at least the ``key`` argument, then an optional value and type:: from sqlalchemy import bindparam stmt = stmt.bindparams( bindparam('name', value='jack', type_=String), bindparam('timestamp', type_=DateTime) ) Above, we specified the type of :class:`.DateTime` for the ``timestamp`` bind, and the type of :class:`.String` for the ``name`` bind. In the case of ``name`` we also set the default value of ``"jack"``. Additional bound parameters can be supplied at statement execution time, e.g.:: result = connection.execute(stmt, timestamp=datetime.datetime(2012, 10, 8, 15, 12, 5)) The :meth:`_expression.TextClause.bindparams` method can be called repeatedly, where it will re-use existing :class:`.BindParameter` objects to add new information. For example, we can call :meth:`_expression.TextClause.bindparams` first with typing information, and a second time with value information, and it will be combined:: stmt = text("SELECT id, name FROM user WHERE name=:name " "AND timestamp=:timestamp") stmt = stmt.bindparams( bindparam('name', type_=String), bindparam('timestamp', type_=DateTime) ) stmt = stmt.bindparams( name='jack', timestamp=datetime.datetime(2012, 10, 8, 15, 12, 5) ) The :meth:`_expression.TextClause.bindparams` method also supports the concept of **unique** bound parameters. These are parameters that are "uniquified" on name at statement compilation time, so that multiple :func:`_expression.text` constructs may be combined together without the names conflicting. To use this feature, specify the :paramref:`.BindParameter.unique` flag on each :func:`.bindparam` object:: stmt1 = text("select id from table where name=:name").bindparams( bindparam("name", value='name1', unique=True) ) stmt2 = text("select id from table where name=:name").bindparams( bindparam("name", value='name2', unique=True) ) union = union_all( stmt1.columns(column("id")), stmt2.columns(column("id")) ) The above statement will render as:: select id from table where name=:name_1 UNION ALL select id from table where name=:name_2 .. versionadded:: 1.3.11 Added support for the :paramref:`.BindParameter.unique` flag to work with :func:`_expression.text` constructs. z?This text() construct doesn't define a bound parameter named %rræN) rtrIrGÚKeyErrorrrêrrƒÚitemsrU) rPÚbindsÚnames_to_valuesÚ new_paramsr~Úexistingrër<r8s rrzzTextClause.bindparamss–€ðH)-Ô(8×(=Ò(=Ñ(?Ô(?Ð?ˆÔ˜:àð 6ð 6ˆDð 6ð& d¤nÔ5ð26 ˜8Ô-Ñ.Ð.øõð ð ð Ý”ÝÔ%ð3Ø59´^ñDñôð%(ðñôððððððøøøøð øøøð*×/Ò/Ñ1Ô1ð >ð >‰JˆCð >Ø% cœ?ð#+×"6Ò"6°uÑ"=Ô"= ˜3‘øõð ð ð Ý”ÝÔ%ð3Ø58ñ9ñôð%(ðñôððððððøøøøð øøøð >ð >s-¦ >¾ BÁ0A=Á=BÂCÃ C?Ã +C:Ã:C?zsqlalchemy.sql.selectablecó²‡—ˆfd„|D¦«}d„‰ ¦«D¦«}| |||zt|¦«o|¬¦«S)a£Turn this :class:`_expression.TextClause` object into a :class:`.TextAsFrom` object that can be embedded into another statement. This function essentially bridges the gap between an entirely textual SELECT statement and the SQL expression language concept of a "selectable":: from sqlalchemy.sql import column, text stmt = text("SELECT id, name FROM some_table") stmt = stmt.columns(column('id'), column('name')).alias('st') stmt = select([mytable]).\ select_from( mytable.join(stmt, mytable.c.name == stmt.c.name) ).where(stmt.c.id > 5) Above, we pass a series of :func:`_expression.column` elements to the :meth:`_expression.TextClause.columns` method positionally. These :func:`_expression.column` elements now become first class elements upon the :attr:`.TextAsFrom.c` column collection, just like any other selectable. The column expressions we pass to :meth:`_expression.TextClause.columns` may also be typed; when we do so, these :class:`.TypeEngine` objects become the effective return type of the column, so that SQLAlchemy's result-set-processing systems may be used on the return values. This is often needed for types such as date or boolean types, as well as for unicode processing on some dialect configurations:: stmt = text("SELECT id, name, timestamp FROM some_table") stmt = stmt.columns( column('id', Integer), column('name', Unicode), column('timestamp', DateTime) ) for id, name, timestamp in connection.execute(stmt): print(id, name, timestamp) As a shortcut to the above syntax, keyword arguments referring to types alone may be used, if only type conversion is needed:: stmt = text("SELECT id, name, timestamp FROM some_table") stmt = stmt.columns( id=Integer, name=Unicode, timestamp=DateTime ) for id, name, timestamp in connection.execute(stmt): print(id, name, timestamp) The positional form of :meth:`_expression.TextClause.columns` also provides the unique feature of **positional column targeting**, which is particularly useful when using the ORM with complex textual queries. If we specify the columns from our model to :meth:`_expression.TextClause.columns`, the result set will match to those columns positionally, meaning the name or origin of the column in the textual SQL doesn't matter:: stmt = text("SELECT users.id, addresses.id, users.id, " "users.name, addresses.email_address AS email " "FROM users JOIN addresses ON users.id=addresses.user_id " "WHERE users.id = 1").columns( User.id, Address.id, Address.user_id, User.name, Address.email_address ) query = session.query(User).from_statement(stmt).options( contains_eager(User.addresses)) .. versionadded:: 1.1 the :meth:`_expression.TextClause.columns` method now offers positional column targeting in the result set when the column expressions are passed purely positionally. The :meth:`_expression.TextClause.columns` method provides a direct route to calling :meth:`_expression.FromClause.alias` as well as :meth:`_expression.SelectBase.cte` against a textual SELECT statement:: stmt = stmt.columns(id=Integer, name=String).cte('st') stmt = select([sometable]).where(sometable.c.id == stmt.c.id) .. versionadded:: 0.9.0 :func:`_expression.text` can now be converted into a fully featured "selectable" construct using the :meth:`_expression.TextClause.columns` method. có€•—g|]:}|j‰vr-t|j‰ |j¦«¦«n|‘Œ;Sr…)r<rr\)rÚcolrQs €rú z&TextClause.columns..sZø€ð! ð! ð! ððŒw˜%ÐÐõ ˜œ %§)¢)¨C¬GÑ"4Ô"4Ñ5Ô5Ð5àð! ð! ð! rcó4—g|]\}}t||¦«‘ŒSr…©r)rr<r%s rrŠz&TextClause.columns..s3€ð ð ð Ù)3¨¨eL˜˜eÑ$Ô$ð ð ð r)Ú positional)r‚Ú TextAsFromr )rPrÚcolsrQÚpositional_input_colsÚkeyed_input_colss ` rrzTextClause.columnsŸs–ø€ðL! ð! ð! ð! ðð ! ñ! ô!

The ``CASE`` construct in SQL is a conditional object that acts somewhat analogously to an "if/then" construct in other languages. It returns an instance of :class:`.Case`. :func:`.case` in its usual form is passed a list of "when" constructs, that is, a list of conditions and results as tuples:: from sqlalchemy import case stmt = select([users_table]).\ where( case( [ (users_table.c.name == 'wendy', 'W'), (users_table.c.name == 'jack', 'J') ], else_='E' ) ) The above statement will produce SQL resembling:: SELECT id, name FROM user WHERE CASE WHEN (name = :name_1) THEN :param_1 WHEN (name = :name_2) THEN :param_2 ELSE :param_3 END When simple equality expressions of several values against a single parent column are needed, :func:`.case` also has a "shorthand" format used via the :paramref:`.case.value` parameter, which is passed a column expression to be compared. In this form, the :paramref:`.case.whens` parameter is passed as a dictionary containing expressions to be compared against keyed to result expressions. The statement below is equivalent to the preceding statement:: stmt = select([users_table]).\ where( case( {"wendy": "W", "jack": "J"}, value=users_table.c.name, else_='E' ) ) The values which are accepted as result values in :paramref:`.case.whens` as well as with :paramref:`.case.else_` are coerced from Python literals into :func:`.bindparam` constructs. SQL expressions, e.g. :class:`_expression.ColumnElement` constructs, are accepted as well. To coerce a literal string expression into a constant expression rendered inline, use the :func:`_expression.literal_column` construct, as in:: from sqlalchemy import case, literal_column case( [ ( orderline.c.qty > 100, literal_column("'greaterthan100'") ), ( orderline.c.qty > 10, literal_column("'greaterthan10'") ) ], else_=literal_column("'lessthan10'") ) The above will render the given constants without using bound parameters for the result values (but still for the comparison values), as in:: CASE WHEN (orderline.qty > :qty_1) THEN 'greaterthan100' WHEN (orderline.qty > :qty_2) THEN 'greaterthan10' ELSE 'lessthan10' END :param whens: The criteria to be compared against, :paramref:`.case.whens` accepts two different forms, based on whether or not :paramref:`.case.value` is used. In the first form, it accepts a list of 2-tuples; each 2-tuple consists of ``(, )``, where the SQL expression is a boolean expression and "value" is a resulting value, e.g.:: case([ (users_table.c.name == 'wendy', 'W'), (users_table.c.name == 'jack', 'J') ]) In the second form, it accepts a Python dictionary of comparison values mapped to a resulting value; this form requires :paramref:`.case.value` to be present, and values will be compared using the ``==`` operator, e.g.:: case( {"wendy": "W", "jack": "J"}, value=users_table.c.name ) :param value: An optional SQL expression which will be used as a fixed "comparison point" for candidate values within a dictionary passed to :paramref:`.case.whens`. :param else\_: An optional SQL expression which will be the evaluated result of the ``CASE`` construct if all expressions within :paramref:`.case.whens` evaluate to false. When omitted, most databases will produce a result of NULL if none of the "when" expressions evaluate to true.

The first is that it renders the ``CAST`` expression within the resulting SQL string. The second is that it associates the given type (e.g. :class:`.TypeEngine` class or instance) with the column expression on the Python side, which means the expression will take on the expression operator behavior associated with that type, as well as the bound-value handling and result-row-handling behavior of the type. .. versionchanged:: 0.9.0 :func:`.cast` now applies the given type to the expression such that it takes effect on the bound-value, e.g. the Python-to-database direction, in addition to the result handling, e.g. database-to-Python, direction. An alternative to :func:`.cast` is the :func:`.type_coerce` function. This function performs the second task of associating an expression with a specific type, but does not render the ``CAST`` expression in SQL. :param expression: A SQL expression, such as a :class:`_expression.ColumnElement` expression or a Python string which will be coerced into a bound literal value. :param type\_: A :class:`.TypeEngine` class or instance indicating the type to which the ``CAST`` should apply. .. seealso:: :ref:`coretutorial_casts` :func:`.type_coerce` - an alternative to CAST that coerces the type on the Python side only, which is often sufficient to generate the correct SQL and data coercion. r$N)rÚto_instancer*r&rArfrg©rPr+r%s rrNz Cast.__init__ò sB€õlÔ(¨Ñ/Ô/ˆŒ Ý'¨ ¸$¼)ÐDÑDÔDˆŒÝ$ T¤YÑ/Ô/ˆŒˆˆrcóR—||jfi|¤Ž|_||jfi|¤Ž|_dSr©rArgrŠs rr‹zCast._copy_internals, s<€Øe˜DœKÐ.Ð.¨2Ð.Ð.ˆŒØ˜% ¤Ð6Ð6°2Ð6Ð6ˆŒˆˆrcó—|j|jfSrr)rs rrŽzCast.get_children0 s€ØŒ{˜DœOÐ+Ð+rcó—|jjSr©rArÈrTs rrÈzCast._from_objects3 ó €àŒ{Ô(Ð(rNr r…rrr)r)Ö sx€€€€€ððð2€Nð80ð80ð80ðt%+ð7ð7ð7ð7ð,ð,ð,ðð)ð)ñ„Xð)ð)ð)rr)cój—eZdZdZdZd„Zefd„Zd„Ze d„¦«Z ejd„¦«Z d d „ZdS)Ú TypeCoercea¾Represent a Python-side type-coercion wrapper. :class:`.TypeCoerce` supplies the :func:`_expression.type_coerce` function; see that function for usage details. .. versionchanged:: 1.1 The :func:`.type_coerce` function now produces a persistent :class:`.TypeCoerce` wrapper object rather than translating the given object in place. .. seealso:: :func:`_expression.type_coerce` :func:`.cast` Útype_coercecón—tj|¦«|_t||j¬¦«|_dS)aêAssociate a SQL expression with a particular type, without rendering ``CAST``. E.g.:: from sqlalchemy import type_coerce stmt = select([type_coerce(log_table.date_string, StringDateTime())]) The above construct will produce a :class:`.TypeCoerce` object, which does not modify the rendering in any way on the SQL side, with the possible exception of a generated label if used in a columns clause context:: SELECT date_string AS anon_1 FROM log When result rows are fetched, the ``StringDateTime`` type processor will be applied to result rows on behalf of the ``date_string`` column. .. note:: the :func:`.type_coerce` construct does not render any SQL syntax of its own, including that it does not imply parenthesization. Please use :meth:`.TypeCoerce.self_group` if explicit parenthesization is required. In order to provide a named label for the expression, use :meth:`_expression.ColumnElement.label`:: stmt = select([ type_coerce(log_table.date_string, StringDateTime()).label('date') ]) A type that features bound-value handling will also have that behavior take effect when literal values or :func:`.bindparam` constructs are passed to :func:`.type_coerce` as targets. For example, if a type implements the :meth:`.TypeEngine.bind_expression` method or :meth:`.TypeEngine.bind_processor` method or equivalent, these functions will take effect at statement compilation/execution time when a literal value is passed, as in:: # bound-value handling of MyStringType will be applied to the # literal value "some string" stmt = select([type_coerce("some string", MyStringType)]) When using :func:`.type_coerce` with composed expressions, note that **parenthesis are not applied**.

The :class:`.ColumnClause`, a lightweight analogue to the :class:`_schema.Column` class, is typically invoked using the :func:`_expression.column` function, as in:: from sqlalchemy import column id, name = column("id"), column("name") stmt = select([id, name]).select_from("user") The above statement would produce SQL like:: SELECT id, name FROM user :class:`.ColumnClause` is the immediate superclass of the schema-specific :class:`_schema.Column` object. While the :class:`_schema.Column` class has all the same capabilities as :class:`.ColumnClause`, the :class:`.ColumnClause` class is usable by itself in those cases where behavioral requirements are limited to simple SQL expression generation. The object has none of the associations with schema-level metadata or with execution-time behavior that :class:`_schema.Column` does, so in that sense is a "lightweight" version of :class:`_schema.Column`. Full details on :class:`.ColumnClause` usage is at :func:`_expression.column`. .. seealso:: :func:`_expression.column` :class:`_schema.Column` r^NFcóp—|x|_|_||_tj|¦«|_||_dS)a7 Produce a :class:`.ColumnClause` object. The :class:`.ColumnClause` is a lightweight analogue to the :class:`_schema.Column` class. The :func:`_expression.column` function can be invoked with just a name alone, as in:: from sqlalchemy import column id, name = column("id"), column("name") stmt = select([id, name]).select_from("user") The above statement would produce SQL like:: SELECT id, name FROM user Once constructed, :func:`_expression.column` may be used like any other SQL expression element such as within :func:`_expression.select` constructs:: from sqlalchemy.sql import column id, name = column("id"), column("name") stmt = select([id, name]).select_from("user") The text handled by :func:`_expression.column` is assumed to be handled like the name of a database column; if the string contains mixed case, special characters, or matches a known reserved word on the target backend, the column expression will render using the quoting behavior determined by the backend. To produce a textual SQL expression that is rendered exactly without any quoting, use :func:`_expression.literal_column` instead, or pass ``True`` as the value of :paramref:`_expression.column.is_literal`. Additionally, full SQL statements are best handled using the :func:`_expression.text` construct. :func:`_expression.column` can be used in a table-like fashion by combining it with the :func:`.table` function (which is the lightweight analogue to :class:`_schema.Table` ) to produce a working table construct with minimal boilerplate:: from sqlalchemy import table, column, select user = table("user", column("id"), column("name"), column("description"), ) stmt = select([user.c.description]).where(user.c.name == 'wendy') A :func:`_expression.column` / :func:`.table` construct like that illustrated above can be created in an ad-hoc fashion and is not associated with any :class:`_schema.MetaData`, DDL, or events, unlike its :class:`_schema.Table` counterpart. .. versionchanged:: 1.0.0 :func:`_expression.column` can now be imported from the plain ``sqlalchemy`` namespace like any other SQL element. :param text: the text of the element. :param type: :class:`_types.TypeEngine` object which can associate this :class:`.ColumnClause` with a type. :param is_literal: if True, the :class:`.ColumnClause` is assumed to be an exact expression that will be delivered to the output with no quoting rules applied regardless of case sensitive settings. the :func:`_expression.literal_column()` function essentially invokes :func:`_expression.column` while passing ``is_literal=True``. .. seealso:: :class:`_schema.Column` :func:`_expression.literal_column` :func:`.table` :func:`_expression.text` :ref:`sqlexpression_literal_column` N)r<rÚtablerr&r*r")rPryr%r"rs rrNzColumnClause.__init__Òs7€ðx $Ð#ˆŒ4”9Ø ˆŒ ÝÔ(¨Ñ/Ô/ˆŒ Ø$ˆŒˆˆrcór—|jsR|jK|jjs?t|d¦«r/t |t ¦«rZ|js|j|jjr@t|d¦«r|j|jkpt|d¦«o|j|jkS|j |j¦«S)Nrrr5) r"rÚ_textualr¯rArrr5rrr¨s rrz%ColumnClause._compare_name_for_result3sÈ€àŒOð @àŒzÐ!ØŒzÔ"ð"å˜5 +Ñ.Ô.ð"õ˜5¥,Ñ/Ô/ð "ðÔ$ð "ð”{Ð*Ø”{Ô+ð+õ ˜E 6Ñ*Ô*ÐF¨t¬y¸E¼JÒ/FðÝ˜˜xÑ(Ô(ÐH¨T¬[¸E¼LÒ-Hð ð”?×/Ò/°´Ñ?Ô?Ð?rcó—|jdS©Nr)rHrTs rÚ _get_tablezColumnClause._get_tableHs€ØŒ}˜WÔ%Ð%rcóN—|j |¦«||jd<dSr)Ú_memoized_propertyÚexpire_instancerH)rPrs rÚ _set_tablezColumnClause._set_tableKs+€ØÔ×/Ò/°Ñ5Ô5Ð5Ø!&ˆŒ gÑÐÐrcó—|j}||gSgSr©r)rPÚts rrÈzColumnClause._from_objectsQs€àŒJˆØˆ=Ø3ˆJàˆIrcó^—tjr|jS|j dd¦«Srœ)rrŸrr¢rTs rr¼zColumnClause.descriptionYs.€åŒ9ð AØ”9Ðà”9×#Ò# GÐ-?Ñ@Ô@Ð@rcód—|j|jkr| |j¦«S|jSr)r<rÚ _gen_labelr5rTs rr6zColumnClause._key_label`s-€àŒ8t”yÒ Ð Ø—?’? 4¤8Ñ,Ô,Ð,à”;Ðrcó6—| |j¦«Sr©r)rrTs rr5zColumnClause._labelgs€àŠ˜tœyÑ)Ô)Ð)rcó—|jduSrr%rTs rr7z,ColumnClause._render_label_in_columns_clauseks€àŒz Ð%Ð%rcó:—| |jd¬¦«S)NF)Ú dedupe_on_keyr+rTs rÚ _ddl_labelzColumnClause._ddl_labelos€àŠ˜tœy¸ˆÑ>Ô>Ð>rTcóŠ—|j}|jrdS|/|jr't|dd¦«r-|j dd¦«dz|jzdz|z}n |jdz|z}t|dd¦«8t|t¦«r |j |_ n]t||j ¦«}nGt|jdd¦«1t|t¦«rJ‚t||jj ¦«}|r;||j vr2|}d}||j vr#|dzt|¦«z}|dz }||j v°#|}t|¦«S|S)NÚschemaú.r?rLr) rr"Únamed_with_columnrír1ÚreplacerrArBrLrQr r)rPrr.r&r.r5Úcounters rr)zColumnClause._gen_labelssj€ØŒJˆàŒ?ð) Ø4à ‰]˜qÔ2‰]Ýq˜( DÑ)Ô)ð ,Øœ×(Ò(¨¨cÑ2Ô2°SÑ8¸1¼6ÑAÀCÑGÈ$ÑNàœ ™ tÑ+õt˜W dÑ+Ô+Ð7Ý˜e¥[Ñ1Ô1ð;Ø"&¤*E”KKå'¨¨t¬zÑ:Ô:EEÝ˜œ ¨$Ñ/Ô/Ð;õ& e[Ñ9Ô9Ð9Ð9Ð9Ý# E¨1¬6¬<Ñ8Ô8àð #ð˜AœC<<Ø"FØGØ A¤C˜-˜-Ø!&¨¡s°7©|¬|Ñ!;˜Ø 1™˜ð!

This ``quote`` flag, when set to ``True`` or ``False``, overrides automatic quoting behavior for this identifier in order to either unconditionally quote or to not quote the name. If left at its default of ``None``, quoting behavior is applied to the identifier on a per-backend basis based on an examination of the token itself. A :class:`.quoted_name` object with ``quote=True`` is also prevented from being modified in the case of a so-called "name normalize" option. Certain database backends, such as Oracle, Firebird, and DB2 "normalize" case-insensitive names as uppercase. The SQLAlchemy dialects for these backends convert from SQLAlchemy's lower-case-means-insensitive convention to the upper-case-means-insensitive conventions of those backends. The ``quote=True`` flag here will prevent this conversion from occurring to support an identifier that's quoted as all lower case against such a backend. The :class:`.quoted_name` object is normally created automatically when specifying the name for key schema constructs such as :class:`_schema.Table`, :class:`_schema.Column`, and others. The class can also be passed explicitly as the name to any function that receives a name which can be quoted. Such as to use the :meth:`_engine.Engine.has_table` method with an unconditionally quoted name:: from sqlalchemy import create_engine from sqlalchemy.sql import quoted_name engine = create_engine("oracle+cx_oracle://some_dsn") engine.has_table(quoted_name("some_table", True)) The above logic will run the "has table" logic against the Oracle backend, passing the name exactly as ``"some_table"`` without converting to upper case. .. versionadded:: 0.9.0 .. versionchanged:: 1.2 The :class:`.quoted_name` construct is now importable from ``sqlalchemy.sql``, in addition to the previous location of ``sqlalchemy.sql.elements``. )rLrÐrÑcó®•—|€dSt||¦«r||j|kr|Stt|¦« ||¦«}||_|Sr)rArLrßrBrG)r©r8rLrPrFs €rrGzquoted_name.__new__)sbø€Øˆ=Ø4õ˜˜sÑ #Ô #ð ØˆM˜Uœ[¨EÒ1Ð1àˆLÝ•[ #Ñ&Ô&×.Ò.¨s°EÑ:Ô:ˆàˆŒ ØˆrcóF—ttj|¦«|jffSr)rBrÚ text_typerLrTs rrËzquoted_name.__reduce__:s€ÝTœ^¨DÑ1Ô1°4´:Ð>Ð>Ð>rcó`—|jr|Stj|¦« ¦«Sr)rLrrRrÐrTs rÚ_memoized_method_lowerz"quoted_name._memoized_method_lower=ó-€ØŒ:ð 0ØˆKå”> $Ñ'Ô'×-Ò-Ñ/Ô/Ð/rcó`—|jr|Stj|¦« ¦«Sr)rLrrRrÑrTs rÚ_memoized_method_upperz"quoted_name._memoized_method_upperCrUrcóÆ—tjr<| dd¦«}tjs| d¦«}d|zSt |¦«S)Nrržz'%s')rÚpy2kr¢Údecoder r¾)rPÚbackslasheds rr¾zquoted_name.__repr__IsZ€ÝŒ9ð &ØŸ+š+ gÐ/AÑBÔBˆKÝ”9ð :Ø)×0Ò0°Ñ9Ô9Ø˜KÑ'Ð'å—<’< Ñ%Ô%Ð%r)rÀr¿rÄrÅÚ __slots__rGrËrTrWr¾r<rSs@rrBrBõs†ø€€€€€ð/ð/ðb*€Iðððððð"?ð?ð?ð0ð0ð0ð0ð0ð0ð&ð&ð&ð&ð&ð&ð&rrBcó4‡—eZdZdZdZdˆfd„ Zd„Zd„ZˆxZS)Ú_truncated_labelzVA unicode subclass used to identify symbolic " "names that may require truncation.r…Ncóz•—t|d|¦«}tt|¦« |||¦«S)NrL)rírßr^rG)r©r8rLrFs €rrGz_truncated_label.__new__Ys7ø€Ý˜˜w¨Ñ.Ô.ˆåÕ% sÑ+Ô+×3Ò3°C¸ÀÑFÔFÐFrcóF—|jtj|¦«|jffSr)rFrrRrLrTs rrËz_truncated_label.__reduce__^s €ØŒ~¥¤¨tÑ 4Ô 4°d´jÐAÐAÐArcó—|Srr…©rPÚmap_s rÚ apply_mapz_truncated_label.apply_maparˆrr) rÀr¿rÄrÅr\rGrËrdr<rSs@rr^r^Ssuø€€€€€ð+ð+ð€IðGðGðGðGðGðGð BðBðBðððððððrr^có—eZdZdZdZdS)ÚconvaMark a string indicating that a name has already been converted by a naming convention. This is a string subclass that indicates a name that should not be subject to any further naming conventions. E.g. when we create a :class:`.Constraint` using a naming convention as follows:: m = MetaData(naming_convention={ "ck": "ck_%(table_name)s_%(constraint_name)s" }) t = Table('t', m, Column('x', Integer), CheckConstraint('x > 5', name='x5')) The name of the above constraint will be rendered as ``"ck_t_x5"``. That is, the existing name ``x5`` is used in the naming convention as the ``constraint_name`` token. In some situations, such as in migration scripts, we may be rendering the above :class:`.CheckConstraint` with a name that's already been converted. In order to make sure the name isn't double-modified, the new name is applied using the :func:`_schema.conv` marker.
