Small examples of Oracle triggers

Implementation features:

Triggers before the data is inserted, checking that the columns in the table with the same properties as the inserted data change the state to false, and then the insert is performed.

Solution:

CREATE OR REPLACE TRIGGER tri_insertbefore inserton tbl_bank_pos_infofor each rowbegin   Set stat='N'   where pos_mer_id =:new. pos_mer_id and pos_term_id =:  Newpos_term_id and stat='Y'; end;
