Question

我有一份SSRS报告，汇总了指定日期范围内的数据集。

我想使用report参数为查询中的聚合函数提供日期范围。这甚至可能吗？

我有使用变量的聚合函数，但是我想更改它，以便用户可以在报告运行之前选择日期范围。

下面是原始的工作聚合函数（在整个查询的上下文中 - 我删除了查询的非相关部分以避免混淆）。

注意@MonthNum和@ReportYear变量被用作COUNT（）函数的条件。我想将这些变量更改为报告参数值，但无法解决此问题。

DECLARE @MonthNum int;
DECLARE @ReportYear int;

SET @MonthNum = CASE WHEN (MONTH(GETDATE())=1) THEN 12 ELSE MONTH(GETDATE()) - 1 END;
SET @ReportYear = CASE WHEN (MONTH(GETDATE())=1) THEN 
YEAR(GETDATE())-1 ELSE YEAR(GETDATE()) END;

SELECT
COUNT(CASE WHEN (MONTH(tblInvoices.fldDeliveredDate) = @MonthNum AND
(YEAR(tblInvoices.fldDeliveredDate)) = @ReportYear) THEN tblSessions.fldStudioNo END) 
AS MonthVolume

FROM tblInvoices INNER JOIN
tblSessions ON tblInvoices.fldSesID = tblSessions.fldSesID INNER JOIN
tblSessionCustom ON tblSessions.fldSesID = tblSessionCustom.fldSessionCustomID 
INNER JOIN
tblCompInfo ON tblSessions.fldStudioNo = tblCompInfo.fldStudioNo

GROUP BY tblSessions.fldStudioNo, tblCompInfo.fldCompName
HAVING (NOT (tblSessions.fldStudioNo LIKE '999'))

提前感谢您提供的任何帮助或指导。非常感谢。

我相信您需要以下内容，您需要在SSRS中创建参数@StartDate和@EndDate，以便它们提供给查询：

DECLARE @MonthNum int;
DECLARE @ReportYear int,
    @StartDate date,
    @EndDate date

SET @MonthNum = CASE WHEN (MONTH(GETDATE())=1) THEN 12 ELSE MONTH(GETDATE()) - 1 END;
SET @ReportYear = CASE WHEN (MONTH(GETDATE())=1) THEN 
YEAR(GETDATE())-1 ELSE YEAR(GETDATE()) END;

SELECT
COUNT(CASE WHEN (MONTH(tblInvoices.fldDeliveredDate) = @MonthNum AND
(YEAR(tblInvoices.fldDeliveredDate)) = @ReportYear) THEN tblSessions.fldStudioNo END) 
AS MonthVolume

FROM tblInvoices INNER JOIN
tblSessions ON tblInvoices.fldSesID = tblSessions.fldSesID INNER JOIN
tblSessionCustom ON tblSessions.fldSesID = tblSessionCustom.fldSessionCustomID 
INNER JOIN
tblCompInfo ON tblSessions.fldStudioNo = tblCompInfo.fldStudioNo
Where tblInvoices.fldDeliveredDate between @StartDate and @EndDate

GROUP BY tblSessions.fldStudioNo, tblCompInfo.fldCompName
HAVING (NOT (tblSessions.fldStudioNo LIKE '999'))

如何在SQL中的聚合函数中引用SSRS报告参数
