获取最小可用id语句

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(&＃39;2010&＃39;,7,&＃39;0&＃39;) id from dual connect by rownum<=rpad(&＃39;2010&＃39;,7,&＃39;9&＃39;)

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)
