创建新的用户时,要指定default  tablespace,否则它会把system表空间当成自己的缺省表空间。这样做是不提倡的。估计原来创建某个用户的时候没有指定缺省表空间,而现在它使用系统表空间的权限被DBA给收回了。 
先用的简单的办法试试,一般缺省的Oracle安装都是有USERS表空间的。 
比如你要在用户(或SCHEMA)usera中建表,那么你用SYSTEM登录ORACLE后,执行如下SQL 
 
 ALTER  USER  usera  QUOTA  UNLIMITED  ON  USERS; 
  如果没有USERS表空间,则会报错,,你可以找一个其他的表空间,从v$tablespace可以看到所有的表空间。

 下面情况sany用户开始创建的时候没有制定default tablespace  ********

SQL> connect sany/as646333
已连接。
SQL> select * from user_sys_privs
  2  ;

USERNAME                      PRIVILEGE                                ADM
------------------------------ ---------------------------------------- ---
SANY                          CREATE SESSION                          NO
SANY                          EXECUTE ANY PROCEDURE                    NO
SANY                          CREATE USER                              NO
SANY                          CREATE TABLE                            NO

SQL> create table bjwh(user_id number(5),user_name varchar2(20),phone varchar2(12),email varchar2(20
));
create table bjwh(user_id number(5),user_name varchar2(20),phone varchar2(12),email varchar2(20))
*
第 1 行出现错误:
ORA-01950: 对表空间 'USERS' 无权限


SQL> connect system/oracle
已连接。
SQL> alter user sany quota unlimited on users;

用户已更改。

SQL> connect sany/as646333
已连接。
SQL>  create table bjwh(user_id number(5),user_name varchar2(20),phone varchar2(12),email varchar2(2
0));

表已创建。

SQL> disconnect
从 Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - Production
With the Partitioning, OLAP and Data Mining options 断开
SQL> desc bjwh
SP2-0640: 未连接
SP2-0641: "DESCRIBE" 需要连接至服务器
SQL> connect sany/as646333
已连接。
SQL> desc bjwh
 名称                                      是否为空? 类型
 ----------------------------------------- -------- ----------------------------
 USER_ID                                            NUMBER(5)
 USER_NAME                                          VARCHAR2(20)
 PHONE                                              VARCHAR2(12)
 EMAIL                                              VARCHAR2(20)


问题解决。

 

create table test1 (
id varchar(20) default '0' not null,
name varchar(20) default '0' not null
)

alter user UserName quota 200M on TableSpaceName

或者:grant unlimited tablespace to username;或grant unlimited tablespace,dba to username;

第 1 行出现错误:
ORA-01950: 对表空间 'USERS'

无权限

后来查一下才发现我创建用户的时候经常忘记quota。一般我们创建用户的时候,一般要用create user wangfan identified by wangfan default tablespace test. 但一定还要加上一句:quota Storage(unlimited, 8K, 10M etc.) on tablespace; 否则就会出现对表空间使用无权限的错误。quota的意思是该用户可以得到在这个tablespace上所得到的空间。后来我就以sysdba的身份登陆,alter user wangfan quota unlimited on test;然后再创建表就没有问题了。
