Oracle 批量导出 Sequence
使用exp工具，以tables的类型导出某个用户下所有的表和数据，发现其中sequence没有被导出。网上搜索之，发现toad貌似有此功能，于是 安装了9.6.1.1版本，结果居然没发现此功能。（可能是我没找到，至少和那位老大的截图不同），最后找到如下脚本，可以将某个用户的全部 sequence查询出来，并拼成创建语句。 代码如下：Java代码 http://www.net527.cn/uploads/allimg/101025/1340043345-0.gif
[*]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 maxvalue999999999999999999999999999 start with 1 increment by 1 cache 20;
[*]create sequence MIAGENTVERSION_VERSION_SEQ minvalue 1 maxvalue999999999999999999999999 start with 121 increment by 1 cache 20;
[*]
方法二:
select dbms_metadata.get_ddl('SEQUENCE',u.object_name) from user_objects u where object_type='SEQUENCE'
结果类似:
CREATE SEQUENCE "MO_VO"."ARTCOMMENT_SEQ" MINVALUE 1 MAXVALUE 999999999999999999999999999 INCREMENT BY 1 START WITH 341 CACHE 20 ORDER NOCYCLE ;
CREATE SEQUENCE "MO_VO"."ARTICLEVISTCECOLLECT_SEQ" MINVALUE 1 MAXVALUE 999999999999999999999999999 INCREMENT BY 1 START WITH 1 CACHE 20 ORDER NOCYCLE ;
CREATE SEQUENCE "MO_VO"."ARTICLEVISTTEMP_SEQ" MINVALUE 1 MAXVALUE 999999999999999999999999999 INCREMENT BY 1 START WITH 82989 CACHE 20 ORDER NOCYCLE ;
CREATE SEQUENCE "MO_VO"."ARTICLEVIST_SEQ" MINVALUE 1 MAXVALUE 999999999999999999999999999 INCREMENT BY 1 START WITH 1675 CACHE 20 ORDER NOCYCLE ;
