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.
