If the given selectable hasn't populated its .c. collection yet, it should at least pass on the message to the contained selectables, but it will return None. This method is currently used by Declarative to allow Table columns to be added to a partially constructed inheritance mapping that may have already produced joins. The method isn't public right now, as the full span of implications and/or caveats aren't yet clear. It's also possible that this functionality could be invoked by default via an event, which would require that selectables maintain a weak referencing collection of all derivations.

The default behavior here is to first produce a SELECT construct from this :class:`_expression.Join`, then to produce an :class:`_expression.Alias` from that. So given a join of the form:: j = table_a.join(table_b, table_a.c.id == table_b.c.a_id) The JOIN by itself would look like:: table_a JOIN table_b ON table_a.id = table_b.a_id Whereas the alias of the above, ``j.alias()``, would in a SELECT context look like:: (SELECT table_a.id AS table_a_id, table_b.id AS table_b_id, table_b.a_id AS table_b_a_id FROM table_a JOIN table_b ON table_a.id = table_b.a_id) AS anon_1 The equivalent long-hand form, given a :class:`_expression.Join` object ``j``, is:: from sqlalchemy import select, alias j = alias( select([j.left, j.right]).\ select_from(j).\ with_labels(True).\ correlate(False), name=name ) The selectable produced by :meth:`_expression.Join.alias` features the same columns as that of the two individual selectables presented under a single name - the individual columns are "auto-labeled", meaning the ``.c.`` collection of the resulting :class:`_expression.Alias` represents the names of the individual columns using a ``_`` scheme:: j.c.table_a_id j.c.table_b_a_id :meth:`_expression.Join.alias` also features an alternate option for aliasing joins which produces no enclosing SELECT and does not normally apply labels to the column names. The ``flat=True`` option will call :meth:`_expression.FromClause.alias` against the left and right sides individually. Using this option, no new ``SELECT`` is produced; we instead, from a construct as below:: j = table_a.join(table_b, table_a.c.id == table_b.c.a_id) j = j.alias(flat=True) we get a result like this:: table_a AS table_a_1 JOIN table_b AS table_b_1 ON table_a_1.id = table_b_1.a_id The ``flat=True`` argument is also propagated to the contained selectables, so that a composite join such as:: j = table_a.join( table_b.join(table_c, table_b.c.id == table_c.c.b_id), table_b.c.a_id == table_a.c.id ).alias(flat=True) Will produce an expression like:: table_a AS table_a_1 JOIN ( table_b AS table_b_1 JOIN table_c AS table_c_1 ON table_b_1.id = table_c_1.b_id ) ON table_a_1.id = table_b_1.a_id The standalone :func:`_expression.alias` function as well as the base :meth:`_expression.FromClause.alias` method also support the ``flat=True`` argument as a no-op, so that the argument can be passed to the ``alias()`` method of any selectable. .. versionadded:: 0.9.0 Added the ``flat=True`` option to create "aliases" of joins without enclosing inside of a SELECT subquery. :param name: name given to the alias. :param flat: if True, produce an alias of the left and right sides of this :class:`_expression.Join` and return the join of those two selectables.

An :class:`_expression.Alias` represents any :class:`_expression.FromClause` with an alternate name assigned within SQL, typically using the ``AS`` clause when generated, e.g. ``SELECT * FROM table AS aliasname``. Similar functionality is available via the :meth:`_expression.FromClause.alias` method available on all :class:`_expression.FromClause` subclasses. In terms of a SELECT object as generated from the :func:`_expression.select` function, the :meth:`_expression.SelectBase.alias` method returns an :class:`_expression.Alias` or similar object which represents a named, parenthesized subquery. When an :class:`_expression.Alias` is created from a :class:`_schema.Table` object, this has the effect of the table being rendered as ``tablename AS aliasname`` in a SELECT statement. For :func:`_expression.select` objects, the effect is that of creating a named subquery, i.e. ``(select ...) AS aliasname``. The ``name`` parameter is optional, and provides the name to use in the rendered SQL. If blank, an "anonymous" name will be deterministically generated at compile time. Deterministic means the name is guaranteed to be unique against other constructs used in the same statement, and will also be the same name for each successive compilation of the same statement object. :param selectable: any :class:`_expression.FromClause` subclass, such as a table, select statement, etc. :param name: string name to be assigned as the alias.

The TABLESAMPLE clause allows selecting a randomly selected approximate percentage of rows from a table.

Common table expressions are a SQL standard whereby SELECT statements can draw upon secondary statements specified along with the primary statement, using a clause called "WITH". Special semantics regarding UNION can also be employed to allow "recursive" queries, where a SELECT statement can draw upon the set of rows that have previously been selected. CTEs can also be applied to DML constructs UPDATE, INSERT and DELETE on some databases, both as a source of CTE rows when combined with RETURNING, as well as a consumer of CTE rows. .. versionchanged:: 1.1 Added support for UPDATE/INSERT/DELETE as CTE, CTEs added to UPDATE/INSERT/DELETE. SQLAlchemy detects :class:`_expression.CTE` objects, which are treated similarly to :class:`_expression.Alias` objects, as special elements to be delivered to the FROM clause of the statement as well as to a WITH clause at the top of the statement. For special prefixes such as PostgreSQL "MATERIALIZED" and "NOT MATERIALIZED", the :meth:`_expression.CTE.prefix_with` method may be used to establish these. .. versionchanged:: 1.3.13 Added support for prefixes. In particular - MATERIALIZED and NOT MATERIALIZED. :param name: name given to the common table expression. Like :meth:`_expression.FromClause.alias`, the name can be left as ``None`` in which case an anonymous symbol will be used at query compile time. :param recursive: if ``True``, will render ``WITH RECURSIVE``. A recursive common table expression is intended to be used in conjunction with UNION ALL in order to derive rows from those already selected. The following examples include two from PostgreSQL's documentation at http://www.postgresql.org/docs/current/static/queries-with.html, as well as additional examples. Example 1, non recursive:: from sqlalchemy import (Table, Column, String, Integer, MetaData, select, func) metadata = MetaData() orders = Table('orders', metadata, Column('region', String), Column('amount', Integer), Column('product', String), Column('quantity', Integer) ) regional_sales = select([ orders.c.region, func.sum(orders.c.amount).label('total_sales') ]).group_by(orders.c.region).cte("regional_sales") top_regions = select([regional_sales.c.region]).\ where( regional_sales.c.total_sales > select([ func.sum(regional_sales.c.total_sales)/10 ]) ).cte("top_regions") statement = select([ orders.c.region, orders.c.product, func.sum(orders.c.quantity).label("product_units"), func.sum(orders.c.amount).label("product_sales") ]).where(orders.c.region.in_( select([top_regions.c.region]) )).group_by(orders.c.region, orders.c.product) result = conn.execute(statement).fetchall() Example 2, WITH RECURSIVE:: from sqlalchemy import (Table, Column, String, Integer, MetaData, select, func) metadata = MetaData() parts = Table('parts', metadata, Column('part', String), Column('sub_part', String), Column('quantity', Integer), ) included_parts = select([ parts.c.sub_part, parts.c.part, parts.c.quantity]).\ where(parts.c.part=='our part').\ cte(recursive=True) incl_alias = included_parts.alias() parts_alias = parts.alias() included_parts = included_parts.union_all( select([ parts_alias.c.sub_part, parts_alias.c.part, parts_alias.c.quantity ]). where(parts_alias.c.part==incl_alias.c.sub_part) ) statement = select([ included_parts.c.sub_part, func.sum(included_parts.c.quantity). label('total_quantity') ]).\ group_by(included_parts.c.sub_part) result = conn.execute(statement).fetchall() Example 3, an upsert using UPDATE and INSERT with CTEs:: from datetime import date from sqlalchemy import (MetaData, Table, Column, Integer, Date, select, literal, and_, exists) metadata = MetaData() visitors = Table('visitors', metadata, Column('product_id', Integer, primary_key=True), Column('date', Date, primary_key=True), Column('count', Integer), ) # add 5 visitors for the product_id == 1 product_id = 1 day = date.today() count = 5 update_cte = ( visitors.update() .where(and_(visitors.c.product_id == product_id, visitors.c.date == day)) .values(count=visitors.c.count + count) .returning(literal(1)) .cte('update_cte') ) upsert = visitors.insert().from_select( [visitors.c.product_id, visitors.c.date, visitors.c.count], select([literal(product_id), literal(day), literal(count)]) .where(~exists(update_cte.select())) ) connection.execute(upsert) .. seealso:: :meth:`.orm.query.Query.cte` - ORM version of :meth:`_expression.HasCTE.cte`. r×)rشr´)rKrXrطs r;rصz HasCTE.cte‡s€ُNڈ~ٹ~کd¨¸ˆ~رCشCذCrEr)rMrNrOrirصrQrEr;rىrى€s>€€€€€ًًًgDًgDًgDًgDًgDًgDrErىcَ¾—eZdZdZdZd„Zd„Zed„¦«Zed„¦«Z ed„¦«Z d„Zd „Zed „¦«Z d„Zefd„Zed „¦«Zd„Zd„Zd„ZdS)r3z%Represent a grouping of a FROM clauseعgroupingcَ—||_dSr>rC©rKr8s r;r'zFromGrouping.__init__6s €طˆŒˆˆrEcَ—dSr>rQrJs r;rzFromGrouping._init_collections9َ€طˆrEcَ—|jjSr>)r8rںrJs r;rںzFromGrouping.columns<s €àŒ|ش#ذ#rEcَ—|jjSr>)r8r‌rJs r;r‌zFromGrouping.primary_key@َ €àŒ|ش'ذ'rEcَ—|jjSr>)r8r rJs r;r zFromGrouping.foreign_keysDs €àŒ|ش(ذ(rEcَ6—|j |¦«Sr>)r8rأrٌs r;rأzFromGrouping.is_derived_fromHs€طŒ|×+ز+¨Gر4ش4ذ4rEcَ@—t|jjdi|¤ژ¦«S)NrQ)r3r8rb)rKrws r;rbzFromGrouping.aliasKs&€فذ.کDœLش.ذ4ذ4°ذ4ذ4ر5ش5ذ5rEcَ—|jjSr>)r8rrJs r;rzFromGrouping._hide_fromsNrِrEcَ—|jfSr>rCrMs r;rNzFromGrouping.get_childrenRs€ط”ˆذrEcَ,—||jfi|¤ژ|_dSr>rCrIs r;rKzFromGrouping._copy_internalsUs!€طگuکTœ\ذ0ذ0¨Rذ0ذ0ˆŒˆˆrEcَ—|jjSr>)r8r rJs r;r zFromGrouping._from_objectsXs €àŒ|ش)ذ)rEcَ,—t|j|¦«Sr>)rûr8)rKعattrs r;ع__getattr__zFromGrouping.__getattr__\s€فگt”| Tر*ش*ذ*rEcَ—d|jiS©Nr8rCrJs r;ع__getstate__zFromGrouping.__getstate___s€طک4œ<ذ(ذ(rEcَ —|d|_dSrrC)rKعstates r;ع__setstate__zFromGrouping.__setstate__bs€طکYش'ˆŒˆˆrEN)rMrNrOrirjr'rrPrںr‌r rأrbrrNrrKr rrrrQrEr;r3r31s7€€€€€ط/ذ/à€Nًًًً ً ً ًً$ً$ٌ„Xً$ًً(ً(ٌ„Xً(ًً)ً)ٌ„Xً)ً5ً5ً5ً6ً6ً6ًً(ً(ٌ„Xً(ًًًً%+ً1ً1ً1ً1ًً*ً*ٌ„Xً*ً+ً+ً+ً)ً)ً)ً(ً(ً(ً(ً(rEr3cَ‡—eZdZdZdZdZdZ dZ ˆfd„Zd„Z e jd„¦«Zd „Z dd „Ze jd¦«dd„¦«Ze jd¦« dd „¦«Ze jd¦«dd„¦«Zed„¦«ZˆxZS)rہa-Represents a minimal "table" construct.

For those objects that are instances of :class:`_expression.FromClause` (typically :class:`_schema.Table` or :class:`_expression.Alias` objects), the :attr:`_expression.FromClause.c` collection is extracted to form a collection of :class:`_expression.ColumnElement` objects. This parameter will also accept :class:`_expression.TextClause` constructs as given, as well as ORM-mapped classes. .. note:: The :paramref:`_expression.select.columns` parameter is not available in the method form of :func:`_expression.select`, e.g. :meth:`_expression.FromClause.select`. .. seealso:: :meth:`_expression.Select.column` :meth:`_expression.Select.with_only_columns` :param whereclause: A :class:`_expression.ClauseElement` expression which will be used to form the ``WHERE`` clause. It is typically preferable to add WHERE criterion to an existing :class:`_expression.Select` using method chaining with :meth:`_expression.Select.where`. .. seealso:: :meth:`_expression.Select.where` :param from_obj: A list of :class:`_expression.ClauseElement` objects which will be added to the ``FROM`` clause of the resulting statement. This is equivalent to calling :meth:`_expression.Select.select_from` using method chaining on an existing :class:`_expression.Select` object. .. seealso:: :meth:`_expression.Select.select_from` - full description of explicit FROM clause specification. :param autocommit: legacy autocommit parameter. :param bind=None: an :class:`_engine.Engine` or :class:`_engine.Connection` instance to which the resulting :class:`_expression.Select` object will be bound. The :class:`_expression.Select` object will otherwise automatically bind to whatever :class:`~.base.Connectable` instances can be located within its contained :class:`_expression.ClauseElement` members. :param correlate=True: indicates that this :class:`_expression.Select` object should have its contained :class:`_expression.FromClause` elements "correlated" to an enclosing :class:`_expression.Select` object. It is typically preferable to specify correlations on an existing :class:`_expression.Select` construct using :meth:`_expression.Select.correlate`. .. seealso:: :meth:`_expression.Select.correlate` - full description of correlation. :param distinct=False: when ``True``, applies a ``DISTINCT`` qualifier to the columns clause of the resulting statement. The boolean argument may also be a column expression or list of column expressions - this is a special calling form which is understood by the PostgreSQL dialect to render the ``DISTINCT ON ()`` syntax. ``distinct`` is also available on an existing :class:`_expression.Select` object via the :meth:`_expression.Select.distinct` method. .. seealso:: :meth:`_expression.Select.distinct` :param for_update=False: when ``True``, applies ``FOR UPDATE`` to the end of the resulting statement. ``for_update`` accepts various string values interpreted by specific backends, including: * ``"read"`` - on MySQL, translates to ``LOCK IN SHARE MODE``; on PostgreSQL, translates to ``FOR SHARE``. * ``"nowait"`` - on PostgreSQL and Oracle, translates to ``FOR UPDATE NOWAIT``. * ``"read_nowait"`` - on PostgreSQL, translates to ``FOR SHARE NOWAIT``. .. seealso:: :meth:`_expression.Select.with_for_update` - improved API for specifying the ``FOR UPDATE`` clause. :param group_by: a list of :class:`_expression.ClauseElement` objects which will comprise the ``GROUP BY`` clause of the resulting select. This parameter is typically specified more naturally using the :meth:`_expression.Select.group_by` method on an existing :class:`_expression.Select`. .. seealso:: :meth:`_expression.Select.group_by` :param having: a :class:`_expression.ClauseElement` that will comprise the ``HAVING`` clause of the resulting select when ``GROUP BY`` is used. This parameter is typically specified more naturally using the :meth:`_expression.Select.having` method on an existing :class:`_expression.Select`. .. seealso:: :meth:`_expression.Select.having` :param limit=None: a numerical value which usually renders as a ``LIMIT`` expression in the resulting select. Backends that don't support ``LIMIT`` will attempt to provide similar functionality. This parameter is typically specified more naturally using the :meth:`_expression.Select.limit` method on an existing :class:`_expression.Select`. .. seealso:: :meth:`_expression.Select.limit` :param offset=None: a numeric value which usually renders as an ``OFFSET`` expression in the resulting select. Backends that don't support ``OFFSET`` will attempt to provide similar functionality. This parameter is typically specified more naturally using the :meth:`_expression.Select.offset` method on an existing :class:`_expression.Select`. .. seealso:: :meth:`_expression.Select.offset` :param order_by: a scalar or list of :class:`_expression.ClauseElement` objects which will comprise the ``ORDER BY`` clause of the resulting select.

The text of the hint is rendered in the appropriate location for the database backend in use, relative to the given :class:`_schema.Table` or :class:`_expression.Alias` passed as the ``selectable`` argument. The dialect implementation typically uses Python string substitution syntax with the token ``%(name)s`` to render the name of the table or alias. E.g. when using Oracle, the following:: select([mytable]).\ with_hint(mytable, "index(%(name)s ix_mytable)") Would render SQL as:: select /*+ index(mytable ix_mytable) */ ... from mytable The ``dialect_name`` option will limit the rendering of a particular hint to a particular backend. Such as, to add hints for both Oracle and Sybase simultaneously:: select([mytable]).\ with_hint(mytable, "index(%(name)s ix_mytable)", 'oracle').\ with_hint(mytable, "WITH INDEX ix_mytable", 'sybase') .. seealso:: :meth:`_expression.Select.with_statement_hint` N)ع_statement_hintsع_hintsrè)rKr4rعrغs r;rظzSelect.with_hintàsR€ًFذطذ!ش! |°Tذ&:ذ%<ر<ذ!ش!ذ!ذ!àœ+×+ز+¨j¸,ذ-Gبذ,NرOشOˆDŒKˆKˆKrEcَ*—tjd¦«‚)NzvSelect objects don't have a type.

This method is exactly equivalent to as if the original :func:`_expression.select` had been called with the given columns clause. I.e. a statement:: s = select([table1.c.a, table1.c.b]) s = s.with_only_columns([table1.c.b]) should be exactly equivalent to:: s = select([table1.c.b]) This means that FROM clauses which are only derived from the column list will be discarded if the new column list no longer contains that FROM:: >>> table1 = table('t1', column('a'), column('b')) >>> table2 = table('t2', column('a'), column('b')) >>> s1 = select([table1.c.a, table2.c.b]) >>> print(s1) SELECT t1.a, t2.b FROM t1, t2 >>> s2 = s1.with_only_columns([table2.c.b]) >>> print(s2) SELECT t2.b FROM t1 The preferred way to maintain a specific FROM clause in the construct, assuming it won't be represented anywhere else (i.e. not in the WHERE clause, etc.) is to set it using :meth:`_expression.Select.select_from`:: >>> s1 = select([table1.c.a, table2.c.b]).\ ... select_from(table1.join(table2, ... table1.c.a==table2.c.a)) >>> s2 = s1.with_only_columns([table2.c.b]) >>> print(s2) SELECT t2.b FROM t1 JOIN t2 ON t1.a=t2.a Care should also be taken to use the correct set of column objects passed to :meth:`_expression.Select.with_only_columns`. Since the method is essentially equivalent to calling the :func:`_expression.select` construct in the first place with the given columns, the columns passed to :meth:`_expression.Select.with_only_columns` should usually be a subset of those which were passed to the :func:`_expression.select` construct, not those which are available from the ``.c`` collection of that :func:`_expression.select`. That is:: s = select([table1.c.a, table1.c.b]).select_from(table1) s = s.with_only_columns([table1.c.b]) and **not**:: # usually incorrect s = s.with_only_columns([s.c.b]) The latter would produce the SQL:: SELECT b FROM (SELECT t1.a AS a, t1.b AS b FROM t1), t1 Since the :func:`_expression.select` construct is essentially being asked to select both from ``table1`` as well as itself. rN) rrr2r:r%rr¶rrµ)rKrںعrcrىs r;r‏zSelect.with_only_columnsء s€ًL ×زرشذط ˆطً ً ˆAف,¨Qر/ش/ˆAفک!‌\ر*ش*ً =ط—L’Lش);گLر<ش<گطڈIٹIگa‰LŒLˆLˆLطˆشذذrEcَ0—| |¦«dS)z¯Return a new :func:`_expression.select` construct with the given expression added to its WHERE clause, joined to the existing clause via AND, if any.

Passing a :class:`_expression.Join` that refers to an already present :class:`_schema.Table` or other selectable will have the effect of concealing the presence of that selectable as an individual element in the rendered FROM list, instead rendering it into a JOIN clause. While the typical purpose of :meth:`_expression.Select.select_from` is to replace the default, derived FROM clause with a join, it can also be called with individual table elements, multiple times if desired, in the case that the FROM clause cannot be fully derived from the columns clause:: select([func.count('*')]).select_from(table1) N)عappend_fromrآs r;عselect_fromzSelect.select_from6s€ًF ×زکر$ش$ذ$ذ$ذ$rEcَ¦—d|_|r|d€ d|_dSt|j¦« d„|D¦«¦«|_dS)aUReturn a new :class:`_expression.Select` which will correlate the given FROM clauses to that of an enclosing :class:`_expression.Select`. Calling this method turns off the :class:`_expression.Select` object's default behavior of "auto-correlation". Normally, FROM elements which appear in a :class:`_expression.Select` that encloses this one via its :term:`WHERE clause`, ORDER BY, HAVING or :term:`columns clause` will be omitted from this :class:`_expression.Select` object's :term:`FROM clause`. Setting an explicit correlation collection using the :meth:`_expression.Select.correlate` method provides a fixed list of FROM objects that can potentially take place in this process. When :meth:`_expression.Select.correlate` is used to apply specific FROM clauses for correlation, the FROM elements become candidates for correlation regardless of how deeply nested this :class:`_expression.Select` object is, relative to an enclosing :class:`_expression.Select` which refers to the same FROM object. This is in contrast to the behavior of "auto-correlation" which only correlates to an immediate enclosing :class:`_expression.Select`. Multi-level correlation ensures that the link between enclosed and enclosing :class:`_expression.Select` is always via at least one WHERE/ORDER BY/HAVING/columns clause in order for correlation to take place.
