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;
