Plsql trigger if updating
Triggers can be: Trigger names must be unique with respect to other triggers in the same schema.
The rollback to savepoint does not undo changes to any package variables referenced in the trigger.
Each subsequent trigger sees the changes made by the previously fired triggers. The old values are the original values, and the new values are the current values, as set by the most recently fired trigger.
To ensure that multiple triggered actions occur in a specific order, you must consolidate these actions into a single trigger (for example, by having the trigger call a series of procedures). Deptno) AS Amp_list_ Emplist FROM Dept_tab d; procedure can be either a PL/SQL or a Java procedure that is encapsulated in a PL/SQL wrapper.
Because the trigger uses the clause, it might be executed multiple times, such as when updating or deleting multiple rows.
You might omit this clause if you just want to record the fact that the operation occurred, but not examine the data for each row.
Once the trigger is created, entering the following SQL statement: A trigger is either a stored PL/SQL block or a PL/SQL, C, or Java procedure associated with a table, view, schema, or the database itself.
