These are semi-private implementation classes which are only of importance
|

|
|
to database dialect authors; dialects will usually use the classes here
|

|
|
as the base class for their own corresponding classes.

|

This is used to set dialect-wide per-connection options such as

isolation modes, unicode modes, etc.
|

|
|||
|
|
|
|||
|
|
This may involve calling special cursor functions,
|
|||
|
|
issuing a new SELECT on the cursor (or a new one),
|
|||
|
|
or returning a stored value that was
|
|||
|
|
calculated within post_exec().
|
|||
|
|
|
|||
|
|
This function will only be called for dialects
|
|||
|
|
which support "implicit" primary key generation,
|
|||
|
|
keep preexecute_autoincrement_sequences set to False,
|
|||
|
|
and when no explicit id value was bound to the
|
|||
|
|
statement.
|
|||
|
|
|
|||
|
|
The function is called once, directly after
|
|||
|
|
post_exec() and before the transaction is committed
|
|||
|
|
or ResultProxy is generated. If the post_exec()
|
|||
|
|
method assigns a value to `self._lastrowid`, the
|
|||
|
|
value is used in place of calling get_lastrowid().
|
|||
|
|
|
|||
|
|
Note that this method is *not* equivalent to the
|
|||
|
|
``lastrowid`` method on ``ResultProxy``, which is a
|
|||
|
|
direct proxy to the DBAPI ``lastrowid`` accessor
|
|||
|
|
in all cases.
