However, I think its always best to generate the unique ID right above the append statement. And Dennis, yea, the autonumber works fine. However, it can have issues in a relational type of system. These days, I almost always use the globals directory to generate a global ID (from "globalID.db"). This creates a unique ID sandbox wide (or server wide if there are no sandboxes). GlobalID.db--- ID
-------------- Then do something like: [append db=^globalid.db&Autonumber=ID][/append] [commitdatabase db=^globalid.db] [append db=some.db]ID=[lastautonumber]..[/append] [commitdatabase db=some.db] In my sandboxes, I use similar code as above in a function within a preparse script so it is easier to call. [function name=GLOBAL_ID] [exclusivelock db=^globalid.db] [append db=^globalid.db&AUTONUMBER=ID][/append] [commitdatabase db=^globalid.db] [/exclusivelock] [/function] Then simply use it anywhere in the sandbox like so: [GLOBAL_ID] [append db=some.db]ID=[lastautonumber]..[/append] [commitdatabase db=some.db] Donovan -- =o=o=o=o=o=o=o=o=o=o=o=o=o=o=o=o=o=o=o=o=o=o=o=o=o DONOVAN D.
