In this post, I am sharing a T-SQL script to find a list of all CHECK Constraints of SQL Server Database.

Using CHECK Constraints, we are applying business validations or column level validations. Few DBAs also called CHECK Constraint means hidden validation or rule.

When you are working with your transaction system, you may surprise many times because of CHECK constraints.

Periodically, a DBA should prepare the report on defined CHECK Constraints which makes sure about data validation and further implementation.

SELECT 
	S.name + '.' + CC.name AS CheckContraintName 
	,O.name AS ParentObject 
	,O.type_desc AS ParentType 
	,ISNULL(C.name, N'') AS ColumnName 
	,CC.definition AS ContraintDefinition 
	,CC.is_disabled AS IsDisabled 	
FROM sys.check_constraints AS CC 
INNER JOIN sys.schemas AS S 
    ON CC.schema_id = S.schema_id 
INNER JOIN sys.objects AS O 
    ON CC.parent_object_id = O.object_id 
LEFT JOIN sys.columns AS C 
    ON CC.parent_object_id = C.object_id 
    AND CC.parent_column_id = C.column_id 
ORDER BY ParentObject        
        ,ColumnName
