i will explain you in clearly,
I have one form, which has one button in it. i will open the form and click on the button.
In WHEN-BUTTON-PRESSED trigger i'm calling one pl/sql program by passing parameters in it.
I will open the form, and directly click on the button which will directly call the pl/sql script, in the script also no commit is used. but it is updating data in the table.
till i commit the data should not commit in the tables.
this is my scenario. please help me in this
Thanks,
Siva.
