SQL Script to alter ALL Foreign Keys to add ON DELETE CASCADE

Question

I have a SQL 2005 database with approx 250 tables.

I want to temporarily enable ON DELETE CASCADE to all of the Foreign Keys so that I can do a bulk delete easily.

Answer 1

make a new stored procedure, where the only parameter is the name of the table to process. In that procedure, you'll need to loop over sys.foreign_keys and sys.foreign_key_columns to build the proper drop and create syntax, just use a cursor and some prints (KISS).

call this procedure with the syntax:

EXEC sp_msforeachtable 'YourProcedureName ''?'''

and it will run for each table. Take and run the output, and you are done.
