在具有多个IF/CASE条件的SQLite UPDATE触发器中

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;

解决方案

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)
