自己写的3个MySQL触发器insert、update、delete的小例子

-- update 操作的触发器例子
drop trigger if exists csf_maec.tri_economic_dt_update;
delimiter |
create trigger csf_maec.tri_economic_dt_update after update on csf_maec.maec_data
for each row begin   
    insert into csf_maec.maec_data_ecnomic(
       data_id, data_value, audit_status, data_notes, insert_user,
       insert_time, update_user, update_time, delete_user, delete_time,
       audit_user, audit_time, op_flag
    )  
    select new.data_id, new.data_value, new.audit_status, new.data_notes, new.insert_user,
       new.insert_time, new.update_user, now(), new.delete_user, new.delete_time,
       new.audit_user, new.audit_time, concat('update ',user());
         
end|
delimiter ;


-- insert操作的触发器例子
drop trigger if exists csf_maec.tri_economic_dt_insert;

-- delete操作的触发器例子
drop trigger if exists csf_maec.tri_economic_dt_delete;

create trigger csf_maec.tri_economic_dt_delete after delete on csf_maec.maec_data
for each row begin
