Database-Driven Auto-Complete
This section allows the correct choices to be retrieved from a Database file. In order to use this, simply enter the name of the database file, the name of the choice option field, and the name of the choice value field.
The selection criteria can be used to filter the choices similar to an SQL WHERE clause. There is no need to qualify the database file name with a library name, although you can if required. Once the file name has been entered, the "..." button in the choice options and choice value fields will open the dialog box shown below. This dialog lists all the fields in the specified file allowing easy selection of the correct field names.
