Validation Rule: Controlling What the User Enters in a Field
The Default Value property suggests a value to the user, but the Validation Rule property actually limits what the user can place in the field. The user cannot violate validation rules; the database engine strictly enforces them. As with the Default Value property, this property can contain either text or a valid Access expression, but you cannot include userdefined functions in the Validation Rule property. You also can't include references to forms, queries, or tables in the Validation Rule property.If you set the Validation Rule property but not the Validation Text property (covered in the next section), Access automatically displays a standard error message whenever the user violates the validation rule. To display a custom message, you must enter your message text in the Validation Text property.
If you plan to upsize your Access database to a database server, you should be aware that you cannot always easily export validation rules to the server. You must sometimes re-create them using triggers on the server. No Access-defined error messages are displayed when a server validation rule is violated. Your application should be coded to provide the appropriate error messages. You can also perform validation.
Add the following validation rules to the fields in your table. (Access will place quotation marks around the state abbreviations as soon as you tab away from the property.)
