Question

出于某种原因，我能够在SSMS中运行我的SELECT语句，但是当我在SSRS中使用它时，它会说Procedure or function has too many arguments specified。如果我只选择一个参数 - 它会给我结果。但如果我选择2个或更多 - 我得到一个错误。

这是我的全部代码：

DECLARE @ClassCode varchar(max) = '31439,739889'
CREATE TABLE #PolicyNumbers  (PolicyNumber varchar(50))
INSERT INTO #PolicyNumbers SELECT  PolicyNumber FROM tblClassCodesPlazaCommercial T1
WHERE NOT EXISTS (SELECT 1 FROM tblClassCodesPlazaCommercial T2  
WHERE  T1.PolicyNumber = T2.PolicyNumber
        AND ClassCode  IN 
        (SELECT * FROM [dbo].[StringOfStringsToTable](@ClassCode,','))) 
; WITH Earned_to_date AS (
   SELECT Cast('11-30-2016' AS DATE) AS Earned_to_date
), policy_data AS (
    SELECT
        PolicyNumber
,       Cast(PolicyEffectiveDate AS DATE) AS PolicyEffectiveDate
,       Cast(PolicyExpirationDate AS DATE) AS PolicyExpirationDate
,       WrittenPremium
        FROM PlazaInsuranceWPDataSet pid
        WHERE  NOT EXISTS (SELECT PolicyNumber FROM #PolicyNumbers pn WHERE pn.PolicyNumber = pid.PolicyNumber )
        AND State IN ('CA','NV','AZ') 

) 

, digits AS (
SELECT digit
   FROM (VALUES (0), (1), (2), (3), (4)
,      (5), (6), (7), (8), (9)) AS z2 (digit)
), numbers AS (
SELECT 1000 * d4.digit + 100 * d3.digit + 10 * d2.digit + d1.digit AS number
    FROM digits AS d1
    CROSS JOIN digits AS d2
    CROSS JOIN digits AS d3
    CROSS JOIN digits AS d4
), calendar AS (
SELECT
    DateAdd(month, number, '1753-01-01') AS month_of
,   DateAdd(month, number, '1753-02-01') AS month_after
    FROM numbers
), policy_dates AS (
SELECT
   PolicyNumber
,   CASE
        WHEN month_of < PolicyEffectiveDate THEN PolicyEffectiveDate
        ELSE month_of
    END AS StartRiskMonth
,   CASE
       WHEN PolicyExpirationDate < month_after THEN PolicyExpirationDate
       WHEN Earned_to_date.Earned_to_date < month_after THEN Earned_to_date
       ELSE month_after
    END AS EndRiskMonth
,   DateDiff(day, PolicyEffectiveDate, PolicyExpirationDate) AS policy_days
,   WrittenPremium
    FROM policy_data
    JOIN calendar
        ON (policy_data.PolicyEffectiveDate < calendar.month_after
        AND calendar.month_of < policy_data.PolicyExpirationDate)
    CROSS JOIN Earned_to_date
    WHERE  month_of < Earned_to_date
)
SELECT      PolicyNumber,
            --ClassCode,
            Year(StartRiskMonth) as YearStartRisk, 
            Month(StartRiskMonth) as MonthStartRisk,
            c.YearNum,c.MonthNum,
            convert(varchar(7), StartRiskMonth, 120) as RiskMonth,
            sum(WrittenPremium * DateDiff(day, StartRiskMonth, EndRiskMonth) / policy_days) as EarnedPremium
FROM        tblCalendar  c
LEFT  JOIN policy_dates l ON c.YearNum=Year(l.StartRiskMonth) and c.MonthNum = Month(l.StartRiskMonth) AND l.StartRiskMonth BETWEEN '01-01-2012' AND  '10-31-2016'
WHERE c.YearNum Not IN (2017) --and PolicyNumber = 'PACA1000191-00'
GROUP BY    convert(varchar(7), StartRiskMonth, 120),
            Year(StartRiskMonth) , Month(StartRiskMonth),
            c.YearNum,c.MonthNum,PolicyNumber
ORDER BY    PolicyNumber,c.YearNum,c.MonthNum
DROP TABLE #PolicyNumbers

我正在使用正常工作的split函数：

ALTER FUNCTION [dbo].[StringOfStringsToTable]
    (
        @Strings varchar(8000),
        @Separator char(1)
    )
RETURNS @StringTable table (String varchar(500))
AS
    BEGIN

        DECLARE @String varchar(500), @Pos int

        SET @Strings = LTRIM(RTRIM(@Strings))+ @Separator
        SET @Pos = CHARINDEX(@Separator, @Strings, 1)

            WHILE @Pos > 0
            BEGIN
                SET @String = LTRIM(RTRIM(LEFT(@Strings, @Pos - 1)))

                IF @String <> '' INSERT INTO @StringTable VALUES (@String)

                SET @Strings = RIGHT(@Strings, LEN(@Strings) - @Pos)
                SET @Pos = CHARINDEX(@Separator, @Strings, 1)
            END

    RETURN
    END

这是SSMS中的结果集：

有一个错误：

在SSRS中的查询设计器中，如果我在顶部使用多个值参数声明变量而不是它的工作原理。

DECLARE @ClassCode varchar(100) = '31439,739889,33528,40199,21289,40427,42594,5283,5251,34489'

但是，如果我取消该陈述而不是收到同样的错误。这是怎么回事？

Answer 1

谢谢你们的建议。在使用SSRS时，我肯定会将我的代码包装到SP中并使用#TempTables退出。但我也通过修改我的数据集上的参数找到了解决我问题的方法。而不是默认参数@Parameters！ClassCode.Value我使用了JOIN函数：

=Join(Parameters!ClassCode.Value,",")

感谢您的帮助

我同意之前的回答。脚本中的临时表是个问题。

如果您将脚本设置为服务器上的存储过程，我相信您将使您的生活更轻松。然后通过连接到存储过程在SSRS中创建数据集。它会很好地处理多个参数。

Answer 3

我从经验中知道SSRS不喜欢临时表。以单个哈希（＃）开头的表。

请将其转换为派生表或全局表格，然后重试。

Here is a link to some examples

Answer 4

在我的报告中使用JOIN(!Parameters!someparameter.Value, ",")可以正常工作。称为SP的报告，在SP中的参数由Split table函数解析，然后加入列以充当过滤器。

Answer 5

为清楚起见，我相信此线程在临时表中得出了错误的结论。

我相信这里的问题（我有同样的问题）是逗号之间的空格。当您输入不带空格的字符串而只是逗号时，它可以工作，但是当您在参数部分（例如，如果您复制粘贴）中输入字符串时，通常以不同的行隔开。将其拉回到逗号分隔的值时，SSRS在每个之间添加一个空格。然后它不起作用。我不确定幕后到底发生了什么，但我知道在空间破损的情况下，如果没有它们，它会起作用。这说明了您介绍的所有情况。您还可以通过参数中的join找到解决方案！就我而言，可能是最相似的情况，代码很简单 join(parameter, ", ")

使用您可以粘贴带空格或不带空格的值，它应该可以工作！希望这能消除任何混乱！

过程或函数指定的参数太多SSRS
