Check Constraint Generator
The Check Constraint (auto assigned) Generator generates values within the value range of the check constraint expression. The generator is automatically assigned to a column for which a certain check constraint is defined. It uses the check constraint expression to limit the value range of the data generated for the column.
The dialog box of the Check Constraint shows the check constraint expression and contains Basic Settings and custom settings. You can customize the generator by changing the basic and custom settings.
