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,

-------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
