oracle 数据库创建

/*分为四步  */
/*注：请修改下面的目录、表空间名、用户名、登录密码 */ 
/*******************************************/


/*第1步：创建临时表空间  */
create temporary tablespace user_temp  
tempfile 'D:\app\324\product\user_temp.dbf' 
size 50m  
autoextend on  
next 50m maxsize 20480m  
extent management local;  
 
/*第2步：创建数据表空间 user_data  */
create tablespace user_data  
logging  
datafile 'D:\app\324\product\user_data.dbf' 
size 50m  
autoextend on  
next 50m maxsize 20480m  
extent management local;  
 
/*第3步：创建用户并指定表空间  用户名：punchweb 登录密码：kdpt*/
create user punchweb identified by kdpt
default tablespace user_data  
temporary tablespace user_temp;  
 
/*第4步：给用户授予权限  用户名：punchweb  */
grant connect,resource,dba to punchweb;


/* 权限方式2  用户名：punchweb */
GRANT 
　　CREATE SESSION, CREATE ANY TABLE, CREATE ANY VIEW ,CREATE ANY INDEX, CREATE ANY PROCEDURE,
　　ALTER ANY TABLE, ALTER ANY PROCEDURE,
　　DROP ANY TABLE, DROP ANY VIEW, DROP ANY INDEX, DROP ANY PROCEDURE,
　　SELECT ANY TABLE, INSERT ANY TABLE, UPDATE ANY TABLE, DELETE ANY TABLE
　　TO punchweb;










/*查看所有用户*/
SELECT * FROM DBA_USERS;
SELECT * FROM ALL_USERS;
SELECT * FROM USER_USERS;




/*查看用户系统权限*/
SELECT * FROM DBA_SYS_PRIVS;
SELECT * FROM USER_SYS_PRIVS;




/*查看用户对象或角色权限*/
SELECT * FROM DBA_TAB_PRIVS;
SELECT * FROM ALL_TAB_PRIVS;
SELECT * FROM USER_TAB_PRIVS;




/*查看所有角色*/
SELECT * FROM DBA_ROLES;




/*查看用户或角色所拥有的角色*/
SELECT * FROM DBA_ROLE_PRIVS;
SELECT * FROM USER_ROLE_PRIVS;




-------遇到no privileges on tablespace 'tablespace '


alter user userquota 10M[unlimited] on tablespace;






/*删除表空间*/
DROP TABLESPACE tablespacename INCLUDING CONTENTS  AND DATAFILES CASCADE CONSTRAINTS;
/*删除用户 */
DROP USER punchweb CASCADE
