我们在学习Oracle时，常常要用到数据进行测试，那么建表和数据就成了必要的了。

create table EMP
(
EMPNO NUMBER(4) PRIMARY KEY,
ENAME VARCHAR2(10),
JOB VARCHAR2(9),
MGR NUMBER(4),
HIREDATE DATE,
SAL NUMBER(7,2),
COMM NUMBER(7,2),

);

CREATE TABLE Depth(
DEPTNO NUMBER(4),
DNAME VARCHAR2(14),
LOC VARCHAR2(13)
);
CREATE TABLE Salgrade
(
GRADE NUMBER,
LOSAL  NUMBER,
HISAL NUMBER

CREATE TABLE Bonus
(
ENAME VARCHAR(10),
JOB VARCHAR2(9),
SAL NUMBER,
COMM NUMBER
