To define a domain constraint:
| 1. | From the menu bar choose Define, Constraints, Domain. |
| The Domain Constraints window appears. |
| 2. | Enter the requested information. (See the What's This? help for more details.) Click on the Action tab to fill out the Message and Make Sure That fields. |
Keep the following in mind:
•When defining a restrictive domain constraint, skip the Make Sure That field. •When defining a corrective domain constraint, specify the correction in the Make Sure That field, and optionally a condition in the Do Not Allow That field. | 3. | Click the Check button to have your constraint checked, or choose Special, Check Constraint from the menu bar. |
| If the constraint is correct, the Correct field is checked. |
| 4. | Save your changes in the database. |
USoft Developer lets you document your domain constraints by giving them comments or descriptions. For more information, see "How to Comment on a Domain Constraint".
