Hi there 785434,
(This is a generic SQL question relating to Database Triggers, please post future questions of this type into the relevant forum area.)
Moderator, please move this if able
I use Before Update and Before Delete Triggers to record a 'snapshot' of the row being changed in my applications.
Example:
CREATE TABLE TEST
DATA VARCHAR2(64 CHAR),
CREATING_USERID VARCHAR2(20 CHAR) DEFAULT user NOT NULL,
CREATED_DATE DATE NOT NULL,
CHANGED_BY_USERID VARCHAR2(20 CHAR),
CHANGED_DATE DATE
LOGGING
STORAGE
(MAXEXTENTS UNLIMITED);
CREATE TABLE TEST_HISTORY
DATA VARCHAR2(64 CHAR),
CREATING_USERID VARCHAR2(20 CHAR) DEFAULT user NOT NULL,
CREATED_DATE DATE NOT NULL,
CHANGED_BY_USERID VARCHAR2(20 CHAR),
CHANGED_DATE DATE,
CHANGE_DESCRIPTION
NOLOGGING
STORAGE
(MAXEXTENTS UNLIMITED);
CREATE OR REPLACE TRIGGER TRG_BU_TEST
BEFORE UPDATE ON TEST FOR EACH ROW
BEGIN
INSERT /*+ append */ INTO TEST_HISTORY
(DATA, CREATING_USERID, CREATED_DATE, CHANGED_BY_USERID, CHANGED_DATE, CHANGE_DESCRIPTION)
VALUES
(:old.DATA, :old.CREATING_USERID, :old.CREATED_DATE, USER, SYSDATE, 'UPDATE');
END;
CREATE OR REPLACE TRIGGER TRG_BD_TEST
BEFORE DELETE ON TEST FOR EACH ROW
BEGIN
INSERT /*+ append */ INTO TEST_HISTORY
(DATA, CREATING_USERID, CREATED_DATE, CHANGED_BY_USERID, CHANGED_DATE, CHANGE_DESCRIPTION)
VALUES
(:old.DATA, :old.CREATING_USERID, :old.CREATED_DATE, USER, SYSDATE, 'DELETE');
END;
Using triggers like this will record who made an update or delete to the database and record the row before it was changed.
Note that this method might not be suitable for very high transaction rates.
You will need to 'clear' these history tables as part of routine maintenance.
Hope that this Helps.
Ronald.
