在触发器中如何获取多个条件检查LIKE

CREATE TRIGGER record_big_order AFTER INSERT ON orders BEGIN IF new.value > 1000000 THEN INSERT INTO big_orders (customer_name, salesman_id, value,Mark) VALUES (new.customer_name, new.salesman_id, new.value,'1') END IF; IF new.value > 2000000 THEN INSERT INTO big_orders (customer_name, salesman_id, value,Mark) VALUES (new.customer_name, new.salesman_id, new.value,'2') END IF; IF new.value > 3000000 THEN INSERT INTO big_orders (customer_name, salesman_id, value,Mark) VALUES (new.customer_name, new.salesman_id, new.value,'3') END IF; END; 推荐答案

您可以尝试下面的INSERT语句-

INSERT INTO big_orders (customer_name, salesman_id, value,Mark) VALUES (new.customer_name, new.salesman_id, new.value, CASE WHEN new.value > 3000000 THEN '3' WHEN new.value > 2000000 THEN '2' WHEN new.value > 1000000 THEN '1' END)
