Question

I want to create a trigger in foxpro that will execute after every update in my db table, for example JobActivity.After every update, the trigger should insert the update time in the table JobActivity.

Answer 1

Instead of AFTER the update, you could apply a Record RULE validation (as @Stuart Dunkeld mentions) that is applied against the entire record before the insert/update is processed.

Go to your database container and create a stored procedure something like

FUNCTION SP_LastUpdated()
   replace LastEditDT WITH DATETIME()
   RETURN .t.
ENDFUNC

Then, for the record validation rule, put in SP_LastUpdated().
