On_UPDATE [message #150344]

Is anyone aware of the syntax to call an On-UPDATE trigger from a when-button-pressed button?

What I basically need to do is update a record using a button, so when it is pressed it updates the record. Only problem is that I dont know how to call an On-UPDATE trigger using a when-button-pressed procedure.

Can anyone help?

I'd probably place the code of the ON-UPDATE trigger in a program unit and call that PU.

You could use the EXECUTE_TRIGGER() built-in but I don't recommend it. It messes with the trigger firing sequence.

Thanks for your help.. but there is an error because you can only use On_UPDATE in a on_UPDATE trigger.. I just dont know how to call an On_UPDATE trigger using an when-button-pressed procedure.

(The error is frm-40740)

That's why I stated that you better put the logic outside the trigger, i.e. in a program unit and call that.

It would help if you could explain a little bit what you are actually trying...

Why do you want to call On-Update? If you want to update the database then just put an 'update' statement into the When-Button-Pressed trigger associated with a button. Remember to use 'Standard.Commit' to save the changes as the form will not sense that a change has taken place.
