按整数的大小对包含字符串和整数的列进行排序，将字符串留在末尾

Question

我有一列包含数字和字符串，但该列的数据类型是 varchar。我想 select 并按数字顺序排列 table，字符串应该在最后。可能吗？它的查询是什么？这是我的 ColdFusion 查询：

                order by
                    CAST(thrmempcompany.level_code AS INTEGER)

                </cfquery>
            </cfif>

结果是： 1 10 11 12 13 .... 2 3 ... GRDIRECTOR

我希望成绩排序像

Answer 1

在您的 order by 条款中使用 isnumeric and case。
像这样：

order by isnumeric(thrmempcompany.level_code) desc, 
         case when isnumeric(thrmempcompany.level_code) then
              cast(thrmempcompany.level_code AS int)
         else
              thrmempcompany.level_code
         end,
         dept_name, 
         tdiv.position_parentpath, 
         div_name

如果值为数字，isnumeric 函数将 return 1，否则为 0，这就是为什么您需要第一部分 desc。

Order a column with strings and integers by the size of integers, leaving strings at the end
