Plsql trigger if updating Xxxdating oc ca

A trigger normally exists in the same database as the table named after the "ON" keyword in the CREATE TRIGGER statement.

When RAISE(IGNORE) is called, the remainder of the current trigger program, the statement that caused the trigger program to execute and any subsequent trigger programs that would have been executed are abandoned. If the statement that caused the trigger program to execute is itself part of a trigger program, then that trigger program resumes execution at the beginning of the next step.Because of the behaviors described above, programmers are encouraged to prefer AFTER triggers over BEFORE triggers.A special SQL function RAISE() may be used within a trigger-program, with the following syntax raise-function: When one of RAISE(ROLLBACK,...), RAISE(ABORT,...) or RAISE(FAIL,...) is called during trigger-program execution, the specified ON CONFLICT processing is performed the current query terminates.Hence explicitly specifying FOR EACH ROW is optional.FOR EACH ROW implies that the SQL statements specified in the trigger may be executed (depending on the WHEN clause) for each database row being inserted, updated or deleted by the statement causing the trigger to fire.
