关于SQL Cookbook里dept与emp表结构以及数据

用MYSQL 写了一下，将number变成int， to_date去掉即可。

DROP TABLE IF EXISTS `dept`;
CREATE TABLE `dept` (
  `DEPTNO` int(2) NOT NULL,
  `DNAME` varchar(14) DEFAULT NULL,
  `LOC` varchar(13) DEFAULT NULL,
  PRIMARY KEY (`DEPTNO`)
) ENGINE=MyISAM DEFAULT CHARSET=latin1;

-- ----------------------------
-- Records of dept
-- ----------------------------
INSERT INTO `dept` VALUES ('', 'ACCOUNTING', 'NEW YORK');
INSERT INTO `dept` VALUES ('', 'RESEARCH', 'DALLAS');
INSERT INTO `dept` VALUES ('', 'SALES', 'CHICAGO');
INSERT INTO `dept` VALUES ('', 'OPERATIONS', 'BOSTON');

DROP TABLE IF EXISTS `emp`;
CREATE TABLE `emp` (
  `EMPNO` int(4) NOT NULL,
  `ENAME` varchar(10) DEFAULT NULL,
  `JOB` varchar(9) DEFAULT NULL,
  `MGR` int(4) DEFAULT NULL,
  `HIREDATE` date DEFAULT NULL,
  `SAL` int(7) DEFAULT NULL,
  `COMM` int(7) DEFAULT NULL,
  `DEPTNO` int(2) DEFAULT NULL,
  PRIMARY KEY (`EMPNO`),
  KEY `FK_DEPTNO` (`DEPTNO`)
) ENGINE=MyISAM DEFAULT CHARSET=latin1;
