Méthode sqlalchemy.Engine.raw_connection

Signature de la méthode raw_connection

def raw_connection(self) -> 'PoolProxiedConnection' 

Description

help(Engine.raw_connection)

Return a "raw" DBAPI connection from the connection pool.

The returned object is a proxied version of the DBAPI
connection object used by the underlying driver in use.
The object will have all the same behavior as the real DBAPI
connection, except that its ``close()`` method will result in the
connection being returned to the pool, rather than being closed
for real.

This method provides direct DBAPI connection access for
special situations when the API provided by
:class:`_engine.Connection`
is not needed.   When a :class:`_engine.Connection` object is already
present, the DBAPI connection is available using
the :attr:`_engine.Connection.connection` accessor.
