本文介紹了在具有多個IF/CASE條件的SQLite UPDATE觸發器中的處理方法，對大家解決問題具有一定的參考價值，需要的朋友們下面隨著小編來一起學習吧！

問題描述

在觸發器中如何獲取多個條件檢查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;

推薦答案

您可以嘗試下面的INSERT語句-

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)
