建个序列

[xiaoyuaixiaofan]

请问 我要建一个序列 生成规则DICTIDRS +5位数字符串，长度始终保持13位 怎么做啊？？

我用的是pl/sql developer oracle数据库

比如说：

DICTIDRS00001
DICTIDRS00002
DICTIDRS00003
DICTIDRS00004
DICTIDRS00005.。。。

建一个普通的序列，使用的时候拼接一下就行

create sequence SEQ_TEST
minvalue 1
maxvalue 99999
start with 1
increment by 1
cache 20;

select 'DICTIDRS' || LPAD(SEQ_TEST.Nextval, 5, '0') as seq from dual connect by rownum <= 10;

SEQ
----------------------------
DICTIDRS00001
DICTIDRS00002
DICTIDRS00003
DICTIDRS00004
DICTIDRS00005
DICTIDRS00006
DICTIDRS00007
DICTIDRS00008
DICTIDRS00009
DICTIDRS00010

select 'DICTIDRS' || LPAD(SEQ_TEST.Nextval, 5, '0') as seq from dua……

我是看 oracle 官方文档的

[luyun2011]

create sequence test
minvalue 1
maxvalue 99999
start with 1
increment by 1
cache 20;

select 'DICTIDRS'||LPAD(test.nextval,5,'0') as seq from dual;
正解！
