SQL Query contraints of a database

Another useful query I was in need of, and found, yesterday. This one is care of Pinal Dave (who writes a very useful blog, which has helped me before), though I added the “Order By” line. This query lists all the constraints of a database. Replace AdventureWorks with your DB name.

USE AdventureWorks;
GO
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’
ORDER BY NameofConstraint
GO
