Hi
I have a postgres 9 database, inside this database I need to create a new table called center_changed that gets inserted by any change that take place in a table called center. So I need to create trigger to do this.
Example:
Table name: center(c_cde, c_dsc, ops_cde, grp_cde);
Now on the table called center , I need to create an INSERT and UPDATE trigger will insert the c_cde of the inserted or updated center into the center_changed table
Please help me
I have this syntax below, but please help me with the overall query.
CREATE TRIGGER check_center
BEFORE INSERT OR UPDATE
ON center FOR EACH ROW
EXECUTE PROCEDURE check_center_changes();
Thanks
