Re: run a program when a file changes

This has to be simpler than I am making it.

Several random times a day a file is cleared and then populated again through DDM .  When that happens I want to automatically run a program that updates another file.

A trigger is on rows, so using a trigger would run the program for every row  -  not a good solution.

I cannot access the original file nor the machine that it is on.


A few minutes ago, I suggested an AFTER DELETE trigger.  Reading some of the other replies to your inquiry, including one you made, it seems you want the triggered action to occur after the table has been repopulated.  In that case, make the trigger an AFTER INSERT trigger, again with FOR EACH STATEMENT.

Still a caveat to attach:  it will only work the way you want if the table is repopulated with a SQL INSERT.  If you were to repopulate using CPYF or some other non-SQL means, the trigger will fire for each row inserted, which is not what you want.
