This example shows how to debug a trigger in dbForge Fusion for Oracle. Use provided scripts to create sample objects in your test database.
Use the script available in How To: Debug a Stored Procedure to the procedure used in the sample below.
Use the script below to create the IU_SCHEDULE_DETAIL trigger that generates an error message in case when Timesheetdate is not equal to the first date of a month.
CREATE OR REPLACE TRIGGER IU_SCHEDULE_DETAIL BEFORE INSERT ON SCHEDULE_DETAIL FOR EACH ROW BEGIN IF (GETFIRSTDAYOFMONTH(:NEW.DATEOUT) <> :NEW.TIMESHEETDATE) THEN RAISE_APPLICATION_ERROR(-20000, ''); END IF; END;
To debug the Oracle trigger:
While opening a trigger the Main view is set as default. You are not able to insert a breakpoint in this view.
Set a breakpoint for the stored procedure that will fire the trigger. Left-click in the gray margin next to the INSERT INTO SCHEDULE.SCHEDULE_DETAIL statement.
Step through the code using the StepInto Step Into button to move directly to the breakpoint. At the INSERT INTO SCHEDULE.SCHEDULE_DETAIL statement, when you click Step Into again, you will step into the trigger.
Step through the trigger until you exit back to the stored procedure, and continue to the end.
There are two database objects in the Call Stack window: the IU_SCHEDULE_DETAIL trigger and the FILLSCHEDULE procedure. You may notice the yellow arrow next to the IU_SCHEDULE_DETAIL trigger which identifies the stack frame where the execution pointer is currently located.
You can get back to the procedure source code by double-clicking the procedure in the Call Stack window.
A green arrow indicates that you have stepped back to the parent code that has called the trigger.
