我的查询有3个参数开始日期,结束日期和位置。查询存储在SQL存储过程中,我在SSRS中调用存储过程(EXEC dbo.ups_Calls @Start,@ End,@ Location)(参见下面的代码)。
sort=Total_ix - count_ix
问题:从SSR查询框调用存储过程(见下文)只是从SSRS位置参数中拉出一个站点,即使我选择了多个位置,但是如果我将查询本身嵌入SSRS然后我能够拉多个站点。

使用存储过程时,它需要能够处理多个参数。 SSRS通常将多值参数作为逗号分隔值传递,因此您可以使用以下函数结合存储过程来处理值:
CREATE FUNCTION [dbo].[udf_Split]
(
@RowData NVARCHAR(MAX),
@Delimeter NVARCHAR(MAX)
)
RETURNS @RtnValue TABLE
(
ID INT IDENTITY(1,1),
Data NVARCHAR(MAX)
)
AS
BEGIN
DECLARE @Iterator INT
SET @Iterator = 1
DECLARE @FoundIndex INT
SET @FoundIndex = CHARINDEX(@Delimeter,@RowData)
WHILE (@FoundIndex>0)
BEGIN
INSERT INTO @RtnValue (data)
SELECT
Data = LTRIM(RTRIM(SUBSTRING(@RowData, 1, @FoundIndex - 1)))
SET @RowData = SUBSTRING(@RowData,
@FoundIndex + DATALENGTH(@Delimeter) / 2,
LEN(@RowData))
SET @Iterator = @Iterator + 1
SET @FoundIndex = CHARINDEX(@Delimeter, @RowData)
END
INSERT INTO @RtnValue (Data)
SELECT Data = LTRIM(RTRIM(@RowData))
RETURN
END
GO
存储过程:
CREATE PROC dbo.Calls
@Start DATETIME=NULL,
@End DATETIME=NULL,
@Location VARCHAR(25)=NULL
AS
BEGIN
SELECT CALLDATE, LOCATION
FROM CALL_DETAILS WITH (NOLOCK)
WHERE CALLDATE BETWEEN @START AND @END
AND LOCATION IN (SELECT DATA FROM [dbo].[udf_Split](@Location,','))
END
GO
