Find Constraints of All Tables in a SQL Server 2005/2008 Database

Here’s a real simple query if you need to list the constraints of all the tables in your database. This query lists the constraints of all the tables in the AdventureWorks database

USE AdventureWorks;
GO
SELECT OBJECT_NAME(object_id) as [Constraint],
OBJECT_NAME(parent_object_id) AS [Table],
type_desc AS [Constraint Type],
create_date AS [Creation Date]
FROM sys.objects
WHERE type_desc LIKE '%CONSTRAINT'
ORDER BY [Table]
GO

OUTPUT

Use
Select * from INFORMATION_SCHEMA.TABLE_CONSTRAINTS

query to get all constrains from the database

Select * from INFORMATION_SCHEMA.TABLE_CONSTRAINTS
WHERE TABLE_NAME = 'tablename'

will give you constrains of a table.
