Returns the exact string that would be sent to the database by calling the
execute() method.

execute().

:param procname: Name of procedure to execute on server.
:type procname: str
:param args: Sequence of parameters to use with procedure.
:type args: tuple or list
Returns the original args.
Compatibility warning: PEP-249 specifies that any modified
parameters must be returned. This is currently impossible
as they are only available by storing them in a server
variable and then retrieved by a query. Since stored
procedures return zero or more result sets, there is no
reliable way to get at OUT or INOUT parameters via callproc.
The server variables are named @_procname_n, where procname
is the parameter above and n is the position of the parameter
(from zero). Once all result sets generated by the procedure
have been fetched, you can issue a SELECT @_procname_0, ...
query using .execute() to get any OUT or INOUT values.
Compatibility warning: The act of calling a stored procedure
itself creates an empty result set. This appears after any
result sets generated by the procedure. This is non-standard
behavior with respect to the DB-API. Be sure to use nextset()
to advance through all result sets; otherwise you may get
disconnected.

S )SSCursora
Unbuffered Cursor, mainly useful for queries that return a lot of data,
or for connections to remote servers over a slow network.
Instead of copying every row of data into a buffer, this will fetch
rows as needed. The upside of this is the client uses much less memory,
and rows are returned much faster when traveling over a slow network
or if the result set is very big.
There are limitations, though. The MySQL protocol doesn't support
returning the total number of rows, so the only way to tell how many rows
there are is to iterate over every row returned. Also, it currently isn't
possible to scroll backwards, as only the current row is held in memory.

Fetch all, as per MySQLdb. Pretty useless for large queries, as
it is buffered. See fetchall_unbuffered(), if you want an unbuffered
generator version of this method.

Fetch all, implemented as a generator, which isn't to standard,
however, it doesn't make sense to return everything in a list, as that
would use ridiculous memory for large result sets.
