BST Suite of templates supports ODBC/SQL file drivers for the reminder, appointments, and resources  Files as described in the File Structures Required(Minimum) help segment.

The "required keys" described in this section need to be included in the dictionary so the template can properly construct the ORDER BY and WHERE statements used in Prop:SQL by the templates.

It determines the driver type automatically and gives you the option of adding Prop:SQL statements as needed.

The only difference you will notice in the templates is an additional prompt button "SQL Settings" that becomes enabled if either the reminder/appointment file, or the resource file has an ODBC/SQL File Driver.
