获取最小可用id语句 其中SELECT rownum id from dual connect by rownum=9 改成相应的最小值最大值区间，比如：www.2cto.com SELECT rownum+rpad(2010,7,0) id from dual connect by rownum=rpad(2010,7,9) Sql代码 select id from (SELECT rownum id from d
获取最小可用id语句
其中SELECT rownum id from dual connect by rownum<=9
改成相应的最小值最大值区间，比如：www.2cto.com
SELECT rownum+rpad('2010',7,'0') id from dual connect by rownum<=rpad('2010',7,'9')
Sql代码
select id from (SELECT rownum id from dual connect by rownum<=9) a where not exists
(select id from tab where id= a.id)
