Question : How to turn off referential integrity for importing/replacing/deleti<wbr />ng validated data

Hi all:

Have a question:
I basically have database 1 and database 2.  Same databases (with regards to tables, etc.), but different values.  I want to
a) delete values in certain table (validated) from database 1 and
b) import the values from database 2 to the same tables that was deleted from database 1.  The key here is that it is important that the original data in database 1 is replaced with data from database 2.

I was wondering if there is any way to globally turn off any validation (referential integrity) on a MS SQL database for this import, then turn it back once I have completed the import.

Thanks!

You mean how to disable a constraint for insert

Disable the constraint

ALTER TABLE tablename NOCHECK CONSTRAINT constraintname

enable the constraint

ALTER TABLE tablename CHECK CONSTRAINT constraintname
