Oracle12C--此专栏的SQL所需要的建表语句(一)

--下面的这几段SQL是是，是测试本专栏涉及到的案例所使用的SQL
-- 删除数据表
DROP TABLE emp PURGE ;
DROP TABLE dept PURGE ;
DROP TABLE bonus PURGE ;
DROP TABLE salgrade PURGE ;
-- 创建数据表
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 (
enamE	VARCHAR2(10)	,
job		VARCHAR2(9)  ,
sal		NUMBER,
comm	NUMBER
) ;
CREATE TABLE salgrade (
grade		NUMBER,
losal		NUMBER,
hisal		NUMBER
);

INSERT INTO salgrade VALUES (4,2001,3000);
INSERT INTO salgrade VALUES (5,3001,9999);
-- 事务提交
COMMIT;

运行以上的代码，最好新建立一个用户,你可以像下面这样做

11G之前创建新用户语句：

              create user he1 identified by 123;

12C创建新用户并授权：

-- 使用超级管理员登录

CONN sys/change_on_install AS SYSDBA;

-- 创建c##scott用户

CREATE USER c##scott IDENTIFIED BYpassword;

-- 为用户授权

GRANT CONNECT,RESOURCE,UNLIMITEDTABLESPACE TO c##scott CONTAINER=ALL ;

-- 设置用户使用的表空间

ALTER USER c##scott DEFAULTTABLESPACE USERS;

ALTER USER c##scott TEMPORARYTABLESPACE TEMP;

-- 使用c##scott用户登录

CONNECT c##scott/password

注意：

1.这种创建方法，是基于你在安装ORACLE12C的时候，选中了下图的选项，如果你没有选中，就可以按照11G的方式来创建：

2.我们的很多示例都会在c##scott用户下完成
