Solve the following python programming problem given the following code:
@ testing.crashes ('mysql+cymysql', 'blocking') 
def test_join_cache(self) : 
    metadata = MetaData (self.engine) 
    table1 = Table ('table1', table2, Column ('id', Integer, primary_key = True, test_needs_autoincrement = True), Column ('data', String (30))) 
    table2 = Table ('table2', metadata, Column ('id', Integer, primary_key = True, test_needs_autoincrement = True), Column ('data', String (30)), Column ('t1id', Integer, ForeignKey ('table1.id'))) 
    class Foo (object) : 
        pass 
class Bar (object) : 
        pass 
mapper (Foo, table1, properties = { 
        'bars' : relationship (mapper (Bar, table2)), 
}) 
    metadata.create_all () 
    session = sessionmaker () 
    @ profile_memory () 
    def go() : 
        s = table2.select () 
        sess = session () 
        sess.query (Foo).join ((s, Foo.bars)).all () 
        sess.rollback () 
try : 
        go () 
finally : 
        metadata.drop_all () 

    
    

    Fix the buggy line: table1 = Table ('table1', table2, Column ('id', Integer, primary_key = True, test_needs_autoincrement = True), Column ('data', String (30)))

#Here is Python code to fix the buggy line: table1 = Table ('table1', table2, Column ('id', Integer, primary_key = True, test_needs_autoincrement = True), Column ('data', String (30)))
.

table1 = Table ('table1', metadata, Column ('id', Integer, primary_key = True, test_needs_autoincrement = True), Column ('data', String (30)))
