Oracle查询所有序列

Oracle查询所有序列：

注意事项：

1.      必须以管理员身份登录；

2.      sequence_owner必须为大写，不管你的用户名是否大写。只有大写才能识别。

--查看当前用户的所有序列 
select SEQUENCE_OWNER,SEQUENCE_NAME from dba_sequences where sequence_owner='用户名';


--查询当前用户的序列总数 
select count(*) from dba_sequences where sequence_owner='用户名';


--示例： 
select SEQUENCE_OWNER,SEQUENCE_NAME from dba_sequences  
where sequence_owner=’WGB;

select count(*) from dba_sequences where sequence_owner=’ WGB’;

SQL> select SEQUENCE_OWNER,SEQUENCE_NAME from dba_sequences
  2  where sequence_owner='WGB';

SEQUENCE_OWNER                 SEQUENCE_NAME
------------------------------ ------------------------------ 
WGB                            SEQ_FOR_TEST
WGB                            SEQ_WGB_ADMIN
WGB                            SEQ_WGB_COMMON
