如果数据有编号和文本之间的空间，可以使用以下命令：

order by cast(right(col,CHARINDEX(' ',reverse(col))) as int)

这是比所有其他我感觉好得多的解决方案 – 2010-08-06 09:26:50

我得到的回答做的工作那么一点点会后整理喜欢与大家分享，这个查询有哪些缺陷。请让我知道

ORDER BY CAST(REPLACE(str, 'Pre-OP ', '') AS INT)

这是一个很好的解决方案。但是，是否有可能使它独立于字符串，因为我将包含Pre-Op，OP，OR等数据。只有更改部分将数字休息保持相同 – 2010-08-06 07:05:22

请在串排序。它会像Select * from Table1 order by Cast(SUBSTRING(ColumnName, 7) as INT) ASC。

试试这个：

Order BY 
    CASE WHEN isnumeric(emp_id) = '1' THEN cast (emp_id AS int) 
     WHEN isnumeric(substring(emp_id, 3, 7))=1 THEN cast (substring(emp_id, 3, 7) AS int) 
     ELSE '99999999' 
    END
