将逗号分隔的字符串转换为整数以用于“IN” SQL操作

Question

我将逗号分隔的数字字符串传递给存储过程，这些参数在使用IN关键字时被使用，但是当我执行带有参数“1,2”的SP时，它会给出错误：

将varchar值“1,2”转换为数据类型int失败。

该存储过程如下：

ALTER PROCEDURE [Reports].[LocationSummary]
    @dtFrom VARCHAR(MAX),
    @dtTo VARCHAR(MAX),
    @passTypeId VARCHAR(MAX),
    @passCategoryId VARCHAR(MAX),
    @passTransId VARCHAR(MAX),
    @printOption VARCHAR(MAX),
    @printLocationId VARCHAR(MAX)
AS
BEGIN
    SELECT Admins.PLocations.ArabicName AS PLocationA, 
           Admins.PLocations.EnglishName AS PLocationE,
           SUM(CASE WHEN Port.Info.Printed = 1 THEN 1 ELSE 0 END) AS Printed,
           SUM(CASE WHEN Port.Info.Printed = 0 THEN 0 ELSE 1 END) AS NotPrinted,
           SUM(CASE WHEN Port.PortPrintLog.PortId IS NOT NULL THEN 1 ELSE 0 END) AS Reprinted

    FROM Port.Info INNER JOIN
           Port.PortRequests ON 
           Port.Info.PassRequestId = Port.PortRequests.ID LEFT JOIN
           Port.PortDefinitions ON 
           Port.PortRequests.PassDefinitionID = Port.PortDefinitions.ID INNER JOIN
           Admins.PortCategories ON 
           Port.PortDefinitions.PassCategoryId = Admins.PortCategories.ID INNER JOIN
           Admins.PortTypes ON 
           Port.PortDefinitions.PassTypeId = Admins.PortTypes.ID  INNER JOIN
           Admins.PortTransactionTypes ON 
           Port.PortDefinitions.PassTransactionTypeId = Admins.PortTransactionTypes.ID INNER JOIN
           Admins.PLocations ON 
           Port.Info.PrintLocationID = Admins.PLocations.ID LEFT JOIN
           Port.PortPrintLog ON Port.PortPrintLog.PortId = Port.Info.ID

    WHERE 
         (@dtFrom IS NOT NULL AND Port.PortRequests.IssuanceDate IS NOT NULL AND Port.PortRequests.IssuanceDate >= @dtFrom)
         AND (@dtTo IS NOT NULL AND Port.PortRequests.ExpiryDate IS NOT NULL AND Port.PortRequests.ExpiryDate <= @dtTo)
         AND ((Admins.PortTypes.ID IN (CAST(@passTypeId AS INT)))
         AND (Admins.PortCategories.ID IN (CAST(@passCategoryId)))
         AND (Admins.PortTransactionTypes.ID IN (CAST(@passTransId)))
         AND (Port.Info.PrintLocationID IN (CAST(@PrintLocationId AS INT))))

    GROUP BY Admins.PrintLocations.ArabicName, Admins.PrintLocations.EnglishName

我该如何避免这个错误？我应该使用一个Split函数来分割字符串吗？你能给我一些关于这个函数的例子吗？

@jyparask提供了动态查询，您可以使用该查询语句，否则请尝试实现以下逻辑。如果有多个列，则需要进行更改。

Declare @var1 as varchar(2000)
Declare @var2 as varchar(2000)
Set @var1 = '31,39,41,45'
Set @var2 = ',' + @var1 + ','
select * from Table1 Where Charindex(','+cast(Col1 as varchar)+',', @var2) > 0

你可能有一个动态的SQL语句：

ALTER PROCEDURE [Reports].[LocationSummary]
    @dtFrom VARCHAR(MAX),
    @dtTo VARCHAR(MAX),
    @passTypeId VARCHAR(MAX),
    @passCategoryId VARCHAR(MAX),
    @passTransId VARCHAR(MAX),
    @printOption VARCHAR(MAX),
    @printLocationId VARCHAR(MAX)
AS
    DECLARE @SQL AS VARCHAR(MAX)
    SET @SQL = 
    'SELECT Admins.PLocations.ArabicName AS PLocationA, 
           Admins.PLocations.EnglishName AS PLocationE,
           SUM(CASE WHEN Port.Info.Printed = 1 THEN 1 ELSE 0 END) AS Printed,
           SUM(CASE WHEN Port.Info.Printed = 0 THEN 0 ELSE 1 END) AS NotPrinted,
           SUM(CASE WHEN Port.PortPrintLog.PortId IS NOT NULL THEN 1 ELSE 0 END) AS Reprinted

    FROM Port.Info INNER JOIN
           Port.PortRequests ON 
           Port.Info.PassRequestId = Port.PortRequests.ID LEFT JOIN
           Port.PortDefinitions ON 
           Port.PortRequests.PassDefinitionID = Port.PortDefinitions.ID INNER JOIN
           Admins.PortCategories ON 
           Port.PortDefinitions.PassCategoryId = Admins.PortCategories.ID INNER JOIN
           Admins.PortTypes ON 
           Port.PortDefinitions.PassTypeId = Admins.PortTypes.ID  INNER JOIN
           Admins.PortTransactionTypes ON 
           Port.PortDefinitions.PassTransactionTypeId = Admins.PortTransactionTypes.ID INNER JOIN
           Admins.PLocations ON 
           Port.Info.PrintLocationID = Admins.PLocations.ID LEFT JOIN
           Port.PortPrintLog ON Port.PortPrintLog.PortId = Port.Info.ID

    WHERE 
         (@dtFrom IS NOT NULL AND Port.PortRequests.IssuanceDate IS NOT NULL AND Port.PortRequests.IssuanceDate >= @dtFrom)
         AND (@dtTo IS NOT NULL AND Port.PortRequests.ExpiryDate IS NOT NULL AND Port.PortRequests.ExpiryDate <= @dtTo)
         AND ((Admins.PortTypes.ID IN (' + @passTypeId + '))
         AND (Admins.PortCategories.ID IN (' + @passCategoryId + '))
         AND (Admins.PortTransactionTypes.ID IN (' + @passTransId + '))
         AND (Port.Info.PrintLocationID IN (' + @PrintLocationId + ')))

    GROUP BY Admins.PrintLocations.ArabicName, Admins.PrintLocations.EnglishName'

    EXEC (@SQL)

将参数传递为1,2时，强制转换为int会导致错误。不要进行强制转换。

此查询不会给出预期结果。 - Dhaval

请确保您的逗号分隔列表中有空格：

(1,2)

不是相同的

(1, 2)
