This information should indicate the user id of the user running a DML statement, the date, the original values of the changed rows and the new values. The audit table needs to track specific columns of concern, including PRODUCTNAME, PRICE, SALESTART, SALEEND, and SALEPRICE. Create a table named BB_PRODCHG_AUDIT that can hold the relevant data. Then create a trigger named BB_AUDIT_TRG that fires on update to this table whenever one of the specified columns in the BB_PRODUCT table is changed.

Update bb_product set salestart = '05-MAY-03', saleend = '12-MAY-03', saleprice = 9 where idproduct = 10;
