The workaround for this is to use variables defined in packages to store information that must be in scope for all timing points.
The following code demonstrates the order in which the timing points are fired.
A database trigger is a stored procedure that automatically executes whenever an event occurs. Oracle initiates an ‘AFTER INSERT’ trigger after an insert event has been occurred and an ‘AFTER UPDATE’ trigger after an update event has been occurred.
CREATE or REPLACE TRIGGER emp_after_insert AFTER INSERT ON emp FOR EACH ROW DECLARE BEGIN insert into emp_backup values (:new.empid, :new.fname, :new.lname); DBMS_OUTPUT.
It is having problems with my Bind Variables : NEW from the sequence, and also the idpay value inserted from another Table.
A trigger defined on a schema fires for each event associated with the owner of the schema (the current user).
A trigger defined on a database fires for each event associated with all users. Compound triggers make it easier to program an approach where you want the actions you implement for the various timing points to share common data. When a trigger is fired, the tables referenced in the trigger action might be currently undergoing changes by SQL statements in other users' transactions.
Now before updating ’empid’ column in ’emp’ table see the ’emp’ and ’emp_backup’ table records.
