def bulk_insert(self, table, rows):
        """Issue a "bulk insert" operation using the current
        migration context.

        This provides a means of representing an INSERT of multiple rows
        which works equally well in the context of executing on a live
        connection as well as that of generating a SQL script.   In the
        case of a SQL script, the values are rendered inline into the
        statement.

        e.g.::

            from alembic import op
            from datetime import date
            from sqlalchemy.sql import table, column
            from sqlalchemy import String, Integer, Date

            # Create an ad-hoc table to use for the insert statement.
            accounts_table = table('account',
                column('id', Integer),
                column('name', String),
                column('create_date', Date)
            )

            op.bulk_insert(accounts_table,
                [
                    {'id':1, 'name':'John Smith',
                            'create_date':date(2010, 10, 5)},
                    {'id':2, 'name':'Ed Williams',
                            'create_date':date(2007, 5, 27)},
                    {'id':3, 'name':'Wendy Jones',
                            'create_date':date(2008, 8, 15)},
                ]
            )
          """
