Comment 5 for bug 507172

Confirmed with Play 1.0.3 and Oracle

In getForeignKeyToggleStmt we need to execute 2 statements:
- one statement to prepare a list of ALTER TABLE
- one statement with all the ALTER TABLE operation

Problem is that getForeignKeyToggleStmt is not designed to execute 2 statements,
so we will have to dig a little bit more

I'll try to propose a fix too asap
