Adding Not-Null Field Constraints

“Not Null” constraints cannot be set or enforced through Iron Speed Designer.  However, you can make fields mandatory on forms, meaning an application user must provide a value in order for the record to be inserted into the database.  (See “Configuring Component Properties” for details.)  You can also provide default field values by entering a Default Value.  To make sure the field is required at the database level, you will need to make changes to the schema at the database level.
