Discussion Board
Default Constraint

The above statement is true. Default constraints apply a value to a column when an INSERT statement does not specify the value for the column. Although default constraints do not enforce a rule like the other constraints we have seen, they do provide the proper values to keep the domain integrity intact. A default can assign a constant value, the value of a system function, or NULL to a column. You can use a default on any column except IDENTITY columns and columns of type timestamp.
