Oracle创建表空间、用户、分配权限语句

/*分为四步 */

/*第1步创建临时表空间 */

create temporary tablespace user_temp

tempfile 'D:\oracle\oradata\Oracle9i\user_temp.dbf'

autoextend on next 50m maxsize 20480m

extent management local;

/*第2步创建数据表空间 */

create tablespace user_data logging datafile 'D:\oracle\oradata\Oracle9i\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 */

create user username

default tablespace user_data

temporary tablespace user_temp;

/*第4步给用户授予权限 */

grant connect,resource,dba to username;

/*删除用户 */

drop user pde cascade;

/*删除表空间 */

DROP TABLESPACE USER_DATA INCLUDING CONTENTS AND DATAFILES;
