Question

I have data used primarily in one table in a database and referenced in several different tables. I need to correct the data. Is it possible to write a “where-used” statement that will search every table in the database and return all tables where the data is referenced?

I am using SQL 2005.

Thanks.

I’ve found this sql statement here:

SELECT OBJECT_NAME(OBJECT_ID) AS NameofConstraint,
SCHEMA_NAME(schema_id) AS SchemaName,
OBJECT_NAME(parent_object_id) AS TableName,
type_desc AS ConstraintType
FROM sys.objects
WHERE type_desc LIKE '%CONSTRAINT'
AND  OBJECT_NAME(OBJECT_ID) LIKE 'FK_%'

NOTE:- I name all foreign key constraints starting with FK_ so it is easy to filter them.
