Oracle中批量导出Sequence

如下脚本，可以将某个用户的全部sequence查询出来，并拼成创建语句。

 select 'create sequence '||sequence_name||   
       ' minvalue '||min_value||   
       ' maxvalue '||max_value||   
       ' start with '||last_number||   
       ' increment by '||increment_by||   
       (case when cache_size=0 then ' nocache' else ' cache '||cache_size end) ||';'  

from dba_sequences where sequence_owner='HR' 
注意：其中的HR，是需要导出sequence的用户，貌似必须大写的说！并且使用该脚本的用户需要有访问dba_sequences的权限。

导出结果如下：

create sequence HIBERNATE_SEQUENCE minvalue 1 maxvalue 999999999999999999999999999 start with 1 increment by 1 cache 20;

create sequence MIAGENTVERSION_VERSION_SEQ minvalue 1 maxvalue 999999999999999999999999 start with 121 increment by 1 cache 20;

如果你只想导出本用户的sequence那就不要那么复杂的写，只写如下语句就可以了：

select 'create sequence '||sequence_name||  
       ' minvalue '||min_value||  
       ' maxvalue '||max_value||  
       ' start with '||last_number||  
       ' increment by '||increment_by||  
       (case when cache_size=0 then ' nocache' else ' cache '||cache_size end) ||';' 
from user_sequences
