6. 创建表数据
CREATE TABLE dept (
deptno NUMBER(2) CONSTRAINT PK_DEPT PRIMARY KEY,
dname VARCHAR2(14) ,
loc VARCHAR2(13) ) ;
CREATE TABLE emp (
empno NUMBER(4) CONSTRAINT PK_EMP PRIMARY KEY,
ename VARCHAR2(10),
job VARCHAR2(9),
mgr NUMBER(4),
hiredate DATE,
sal NUMBER(7,2),
comm NUMBER(7,2),
deptno NUMBER(2) CONSTRAINT FK_DEPTNO REFERENCES DEPT );
CREATE TABLE bonus (x
enamE VARCHAR2(10) ,
job VARCHAR2(9) ,
sal NUMBER,
comm NUMBER ) ;
CREATE TABLE salgrade (
grade NUMBER,
losal NUMBER,
hisal NUMBER );
7插入测试数据-----dept
INSERT INTO dept VALUES (10,‘ACCOUNTING‘,‘NEW YORK‘);
INSERT INTO dept VALUES (20,‘RESEARCH‘,‘DALLAS‘);
INSERT INTO dept VALUES (30,‘SALES‘,‘CHICAGO‘);
INSERT INTO dept VALUES (40,‘OPERATIONS‘,‘BOSTON‘);
7. 长如数据emp
