Removed section in docs/model-api.txt about connection.commit(), which no longer exists

        row = cursor.fetchone()

        return row

If your custom SQL statement alters the data in your database -- for example,

via a ``DELETE`` or ``UPDATE`` -- you'll need to call ``db.commit()``. Example::

    def my_custom_sql2(self):

        from django.db import connection

        cursor = connection.cursor()

        cursor.execute("DELETE FROM bar WHERE baz = %s", [self.baz])

        connection.commit()

``connection`` and ``cursor`` simply use the standard `Python DB-API`_. If

you're not familiar with the Python DB-API, note that the SQL statement in

``cursor.execute()`` uses placeholders, ``"%s"``, rather than adding parameters
