mysql 触发器

题目

构造一个触发器audit_log，在向employees_test表中插入一条数据的时候，触发插入相关的数据到audit中。

环境sql

drop table if exists employees_test;
drop table if exists audit;
 
CREATE TABLE employees_test(
   ID INT PRIMARY KEY     NOT NULL,
   NAME           TEXT    NOT NULL,
   AGE            INT     NOT NULL,
   ADDRESS        CHAR(50),
   SALARY         REAL
);
CREATE TABLE audit(
    emp_no INT NOT NULL,
    NAME TEXT NOT NULL
);
 
INSERT INTO employees_test (ID,NAME,AGE,ADDRESS,SALARY)VALUES (1, 'Paul', 32, 'California', 20000.00 );

触发器创建sql

CREATE TRIGGER audit_log 
AFTER
INSERT
	ON
	employees_test
FOR EACH ROW 
BEGIN 
	INSERT INTO audit(emp_no, NAME) 
	VALUE (NEW.id, NEW.name);
END;
