Disabling foreign key constraint, still can't truncate table? (SQL Server 2005)

Question

I have a table called PX_Child that has a foreign key on PX_Parent. I\'d like to temporarily disable this FK constraint so that I can truncate PX_Parent. I\'m not sure how

Answer 1

You can't truncate the table if there is any foreign key referencing it, including disabled constraints. You either need to drop the foreign key constraints or use the DELETE command.
