我是靠谱客的博主顺利心情，最近开发中收集的这篇文章主要介绍MySQL的emp和dept建表语句和insert语句，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

1.建表
CREATE TABLE DEPT (
   DEPTNO INT (2) NOT NULL,
   DNAME VARCHAR (14),
   LOC VARCHAR (13)
);

ALTER TABLE DEPT ADD CONSTRAINT PK_DEPT PRIMARY KEY (DEPTNO);

CREATE TABLE EMP (
   EMPNO INT (4) NOT NULL,
   ENAME VARCHAR (10),
   JOB VARCHAR (9),
   MGR INT (4),
   HIREDATE date,
   SAL INT (7),
   COMM INT (7),
   DEPTNO INT (2)
);

ALTER TABLE EMP ADD CONSTRAINT PK_EMP PRIMARY KEY (EMPNO);

ALTER TABLE EMP ADD CONSTRAINT FK_DEPTNO FOREIGN KEY (DEPTNO) REFERENCES DEPT (DEPTNO);

2.插入数据

INSERT INTO DEPT (DEPTNO, DNAME, LOC) VALUES (10, 'ACCOUNTING', 'NEW YORK');

INSERT INTO DEPT (DEPTNO, DNAME, LOC) VALUES (20, 'RESEARCH', 'DALLAS');

INSERT INTO DEPT (DEPTNO, DNAME, LOC) VALUES (30, 'SALES', 'CHICAGO');

INSERT INTO DEPT (DEPTNO, DNAME, LOC) VALUES (40, 'OPERATIONS', 'BOSTON');

COMMIT;

INSERT INTO EMP ( EMPNO, ENAME, JOB, MGR, HIREDATE, SAL, COMM, DEPTNO ) VALUES ( 7369, 'SMITH', 'CLERK', 7902, str_to_date('17-12-1980', '%d-%m-%Y'), 800, NULL, 20 );
