Question

我正在为我们的团队自动化一些数据透视表，并且已经成功地重新创建了一个汇总表，该汇总表能够按区域获取所有相关数字，然后使用带有以下代码的union包含汇总行：

SELECT region, round(sum(iif([Entered In Portal] = "Y", 1, 0)) / count(*) * 
100,1) & "%" as [% Entered]
from tblITPortalYTD
where [Compliance Reporting Month] = Forms!frmMonth!Month
group by region
UNION ALL 
SELECT "Total" as region, round(sum(iif([Entered In Portal] = "Y", 1, 0))  / 
count(*) * 100,1) & "%" as [% Entered]
from tblITPortalYTD
where [Compliance Reporting Month] = Forms!frmMonth!Month;

这样可以导致第一个查询返回按区域排序，第二个查询显示为附加到底部作为摘要行。问题是，最好让其中一个区域出现在总行的正上方（超出正常的字母顺序）。

示例：a，b，c，d，e，f，摘要 - ＆gt; a，c，d，e，f，b，摘要

我尝试使用ORDER BY IIF（Region = A，1，IIF（region = B，2,3））排序方法，但它不起作用。如果我单独在第一个查询上使用此方法，则排序完美，但将其与UNION ALL组合会将其覆盖为其原始状态。

这可能吗？

您无法在UNION查询中进行真正的排序。您需要将结果集包装在子查询中，然后按顺序排序：

SELECT * 
FROM
(
    SELECT region
        ,round(sum(iif([Entered In Portal] = "Y", 1, 0)) / count(*) * 100, 1) & "%" AS [% Entered]
    FROM tblITPortalYTD
    WHERE [Compliance Reporting Month] = Forms ! frmMonth ! Month
    GROUP BY region

    UNION ALL

    SELECT "Total" AS region
        ,round(sum(iif([Entered In Portal] = "Y", 1, 0)) / count(*) * 100, 1) & "%" AS [% Entered]
    FROM tblITPortalYTD
    WHERE [Compliance Reporting Month] = Forms ! frmMonth ! Month
)subquery
ORDER BY IIF(Region = A, 1, IIF(region = B, 2, 3))

但是现在，你的总排不能保证在底部抖动。要修复，您可以为每个查询添加一个排序列：

SELECT region , [% Entered] 
FROM
(
    SELECT region
        ,round(sum(iif([Entered In Portal] = "Y", 1, 0)) / count(*) * 100, 1) & "%" AS [% Entered]
        ,IIF(Region = A, 1, IIF(region = B, 2, 3)) as myorder
    FROM tblITPortalYTD
    WHERE [Compliance Reporting Month] = Forms ! frmMonth ! Month
    GROUP BY region

    UNION ALL

    SELECT "Total" AS region
        ,round(sum(iif([Entered In Portal] = "Y", 1, 0)) / count(*) * 100, 1) & "%" AS [% Entered],
        99999 as myorder
    FROM tblITPortalYTD
    WHERE [Compliance Reporting Month] = Forms ! frmMonth ! Month
)subquery
ORDER BY myorder

并根据需要进行调整。
