嵌入和更新触发器后的MySQL

Question

我有一个表test1与列id，名称，指定，salary.I想插入每个记录到test2插入到test1，并更新test2中更新test1中的每个记录

Answer 1

你必须创建两个触发器更新和插入一个尚未测试它，但这样的事情会做。

CREATE TRIGGER new_row_added 
AFTER INSERT ON test1 
FOR EACH ROW 
    UPDATE test2 
     SET name=NEW.name, designation=NEW.designation,salary=NEW.salary 
     WHERE id=NEW.id ; 

CREATE TRIGGER ins_sum AFTER UPDATE ON test1 
    FOR EACH ROW 
    BEGIN 
     IF NEW.ts <> OLD.ts THEN 
      INSERT INTO test2 (name, designation,salary) 
      VALUES(NEW.name, NEW.designation,NEW.salary); 
     END IF; 
    END;
