The SQL CHECK CONSTRAINT ensures that a value for a specific column or columns have satisfied a specified condition. The job of CHECK constraint is, to limit the values for a column of a table.1  The SQL CHECK CONSTRAINT can not be used on a VIEW. 2  The SQL CHECK CONSTRAINT can not be used in a subquery.onstraints can be specified when the table created first with CREATE TABLE statement or at the time of modification of structure of an existing table with ALTER TABLE statement.

Any good SQL Server database will use constraints and other DRI in order to maintain integrity and increase performance. The violation of any constraints leads to an error, and it is rare to see this handled well. Autocommit transaction mode. Letâs create a table that allows us to be able to make a couple of different constraint violations. Youâll have to imagine that this is a part of a contact database that is full of constraints and triggers that will defend against bad data ever reaching the database. Naturally, there will be more in this table.
