订购时省略字母

Question

我有以下查询：

 select U.IdUser,U.memberID,SL.Title from users U
                   inner join statuslist SL on
                   U.idStatus=SL.IdStatus
                   where U.idOrg='1'and isnull(U.memberID,'')!=''
                   order by   U.memberID

它给了我结果：

在这里，我希望B12会员ID在B110之前出现（意味着12来自110之前的原因）。

我怎样才能实现它？

我在下面试过......

select U.IdUser,U.memberID,SL.Title from users U
                   inner join statuslist SL on
                   U.idStatus=SL.IdStatus
                   where U.idOrg='1'and isnull(U.memberID,'')!=''
                   order by     Substring(U.memberID,2,LEN(U.memberID))

但没有给出正确的结果。

请帮帮我。

Answer 1

这是因为order by with strings和order by with numbers：

之间存在差异

select U.IdUser,U.memberID,SL.Title from users U
               inner join statuslist SL on
               U.idStatus=SL.IdStatus
               where U.idOrg='1'and isnull(U.memberID,'')!=''
               order by     CAST(Substring(U.memberID,2,LEN(U.memberID)-1) AS INT);

select U.IdUser,U.memberID,SL.Title from users U
               inner join statuslist SL on
               U.idStatus=SL.IdStatus
               where U.idOrg='1'and isnull(U.memberID,'')!=''
               order by     CONVERT(INT,Substring(U.memberID,2,LEN(U.memberID)-1));
