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.
