SQL Server supports the following classes of constraints: NOT NULL specifies that the column does not accept NULL values. For more information, see Allowing Null Values. CHECK constraints enforce domain integrity by limiting the values that can be put in a column. For more information, see CHECK Constraints. A CHECK constraint specifies a Boolean (evaluates to TRUE, FALSE, or unknown) search condition that is applied to all values that are entered for the column. All values that evaluate to FALSE are rejected. You can specify multiple CHECK constraints for each column.
