Question

我试图想到这个最好的头衔。我有一个非常复杂的查询（使用传统的ASP和SQL服务器），我将使其更简单，例如用途。

这是针对report.asp

SQL = "select EMPL.employeeName, " & _
      "COUNT(BUSINESS.ID) AS theTotal, " & _
      "COUNT(CASE WHEN BUSINESS.ID IS NULL THEN 1 END) as unTouched " & _
      "FROM EMPL Inner Join BUSINESS " & _
      "WHERE EMPL.STATUS = 1 " & _
      "GROUP BY EMPL.employeeName " & _
      "ORDER BY " & theOrder

在HTML部分中，我有一个看起来像这样的表：

<table>
   <tr>
      <th><a href="report.asp?sort=1">Employee</th>
      <th><a href="report.asp?sort=2">Total</th>
      <th><a href="report.asp?sort=3">Untouched</th>
   </tr>
   <tr>
      <td><%=RS("employeeName")%></td>
      <td><%=RS("theTotal")%></td>
      <td><%=RS("unTouched")%></td>
   </tr>
</table>

最后，在页面顶部，我有一个order by子句的select case，如下所示：

theOrder = request.querystring("sort")

SELECT CASE theOrder
   CASE 1
      theOrder = "EMPL.employeeName"
   CASE 2
      theOrder = "theTotal, EMPL.employeeName"
   CASE 3
      theOrder = "unTouched, EMPL.employeeName"
   CASE ELSE
      theOrder = "EMPL.employeeName"
END SELECT

一切都按预期工作正常。现在，我想在结尾处添加一个列（theTotal - unTouched）。

所以我在表行之前的循环代码中添加它：

do while not RS.eof

   TheDIfference = RS("theTotal") - RS("unTouched")

...

我添加了“差异”的表格标题和显示减法的新行，一切都很完美。

这是问题所在。我希望能够按该列排序，就像其他2列一样。所以我试着在我的select语句中添加一行说：

SUM(theTotal - unTouched) AS theDifference

那不行，所以我把它拼写出来：

SUM(COUNT(BUSINESS.ID)- COUNT(CASE WHEN BUSINESS.ID IS NULL THEN 1 END)) AS theDifference

那也没有用。

那么有没有一种正确的方法将它包含在select语句中，以便我可以执行orderby或解决方法，而不必将其放在语句本身中？

感谢任何帮助，谢谢！

Answer 1

因为这两个字段是计算列，然后才能通过别名访问它们，所以需要将它们包装在子查询中。

SELECT E.[employeeName], E.[theTotal], E.[unTouched]
, (E.[theTotal] - E.[unTouched]) [theDifference]
FROM (
  SELECT E.employeeName,
  COUNT(B.ID) [theTotal],
  COUNT(CASE WHEN B.ID IS NULL THEN 1 END) [unTouched]
  FROM EMPL E
  INNER JOIN BUSINESS B ON E.SomeField = B.SomeField
  WHERE E.STATUS = 1
  GROUP BY E.employeeName
) E
ORDER BY E.[employeeName];

INNER JOIN需要加入一些形成EMPL表和BUSINESS表之间关系的字段。

SQL语句 - 使用Count（）＆amp; Sum（） - 和排序
