Hi I need to implement a sign out. Through this sign out, I need to remove the tables or clear the rows of the tables so when the other user log's in, he gets his information on these tables. I am removing and clearing (Everything) the relations and using accept changes(). Yet when I try to remove the tables I get a constraint error telling me that I cant remove the table, to please remove the constraint firsts. Yet, I have done this already. This is really taking valuable time.

I figured it out. The relation object doesn't enforce the foreign key constraints. Turns out each table has a constraints collection. This must be cleared also in order to delete a table.
