Question

在我的查询设计器中，我尝试使用以下查询：

SELECT        Site, LegalConfigNumber, COUNT(*) AS Total
FROM            EPSInfoLive
 iif(@LegalConfigNum  =  0,
WHERE        (InputDate >= @rundate) AND (InputDate <= DATEADD(day, 1, @rundate)),
WHERE        (InputDate >= @rundate) AND (InputDate <= DATEADD(day, 1, @rundate)) AND LegalConfigNumber = @LegalConfigNum)
GROUP BY LegalConfigNumber, Site
ORDER BY Site, LegalConfigNumber

当我尝试测试它时，我收到有关@LegalConfigNum语法错误的消息。我似乎无法找到它的位置。

SSRS查询需要用SQL编写。您正在使用'@iif'混合使用SQL和Visual Basic。 SQL支持CASE语句而不是IIF。但是你不需要这个就是你所展示的。以下陈述应在逻辑上等同：

SELECT
   Site,
   LegalConfigNumber,
   COUNT(*) AS Total
FROM
   EPSInfoLive
WHERE
   (InputDate >= @rundate) AND (InputDate <= DATEADD(day, 1, @rundate))
   AND (LegalConfigNumber = @LegalConfigNum OR @LegalConfigNum  =  0)
GROUP BY LegalConfigNumber, Site
ORDER BY Site, LegalConfigNumber

ssrs iif语法
