TSQL Delete with Referential Integrity

Posted on 2011-05-12

Last Modified: 2012-05-11
Hi Experts,

I need to clear out some tables from a SQL 2008 database that are all nicely referenced to one another.

Is there a script that can delete/truncate a table and reseed it regardless of whether it is referenced or not?

That's the point of a reference . . . so that you don't break parent child relationships.

If you wanted to write a script for it just start at the bottom table (eg: the table that references nothing) and work  your way up.

The other thing you can do is drop the foreign keys but I would not recommend doing that, as you will break the relationships and have dirty data.  Regardless of what you do, make a backup of the database first!
