Signature de la méthode create_all

def create_all(self, bind=None, tables=None, checkfirst=True) 

Description

create_all.__doc__

Create all tables stored in this metadata.

        Conditional by default, will not attempt to recreate tables already
        present in the target database.

        :param bind:
          A :class:`.Connectable` used to access the
          database; if None, uses the existing bind on this ``MetaData``, if
          any.

          .. note:: the "bind" argument will be required in
             SQLAlchemy 2.0.

        :param tables:
          Optional list of ``Table`` objects, which is a subset of the total
          tables in the ``MetaData`` (others are ignored).

        :param checkfirst:
          Defaults to True, don't issue CREATEs for tables already present
          in the target database.
