02.将Linux本地数据导入数据库

1. 在Linux系统页面创建一个data.sql文件　

　准备好数据写入：　

DROP TABLE IF EXISTS EMP;
DROP TABLE IF EXISTS DEPT;
DROP TABLE IF EXISTS SALGRADE;

CREATE TABLE DEPT(DEPTNO int(2) not null ,DNAME VARCHAR(14) ,LOC VARCHAR(13),primary key (DEPTNO));
CREATE TABLE EMP(EMPNO int(4)  not null ,ENAME VARCHAR(10),JOB VARCHAR(9),MGR INT(4),HIREDATE DATE  DEFAULT NULL,SAL DOUBLE(7,2), COMM DOUBLE(7,2),
    primary key (EMPNO),DEPTNO INT(2) );
CREATE TABLE SALGRADE( GRADE INT,LOSAL INT,HISAL INT );

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