Question

我有一个现有的存储过程，它接受两个单值参数。现在我需要更改其中一个参数以接受多个值。我修改了存储过程如下。

    CREATE PROCEDURE [dbo].[GetSpecificationsM1]
@EntityType   NVARCHAR(100)
,@EntityId BIGINT

    AS


    DECLARE @EntityTypeId AS BIGINT


    SET @EntityTypeId=ISNULL((SELECT ID 
                     FROM [ObjectTypes] WHERE [Type]=@EntityType),0)



    SELECT ISNULL([Specifications].[Id],0) AS [SpecificationId]
   ,ISNULL([Specifications].[Measure],'') AS [Measure]
   ,ISNULL([Specifications].[Notes],'') AS [Notes]
   ,ISNULL([UOM].[UOM],'') As UOM
   ,ISNULL(SpecificationsTemplate.Name,'') As Specification
   ,ISNULL(SpecificationsTemplate.Id, 0) AS SpecificationTemplateId
   ,ISNULL(Specifications.EntityId, 0) AS EntityId 
   ,(CASE WHEN ISNULL([SpecificationsTemplate].FieldTypeId,0)=0
   THEN 8 ELSE [SpecificationsTemplate].FieldTypeId END) AS [FieldTypeId]
    ,ISNULL(SpecificationsTemplate.ListId,0) AS ListId
    ,ISNULL([Specifications].[ListItemId],0) AS [ListItemId]
  FROM [SpecificationsTemplate] LEFT OUTER JOIN [Specifications] 
   ON [SpecificationsTemplate].[Id]=[Specifications].[SpecificationTemplateId]

    AND [Specifications].[EntityTypeId]=@EntityTypeId
   LEFT OUTER JOIN [UOM] ON  [SpecificationsTemplate].[UOMId]=[UOM].[Id]
   WHERE   [Specifications].[EntityId] IN (@EntityId) 

   GO

在上面的代码中，我修改了@EntityId以接受代码最后一行中的多个值。但是当我尝试将多个值作为@ EntityId = 9,10,11传递给参数时，我收到错误，因为无法将Varchar转换为BigINt。

请帮助我解决问题。

谢谢！

Answer 1

在您的存储过程中更改参数，其中的条件如下所示

例如：

WHERE ([CostCentre]) collate database_default IN(SELECT Value FROM dbo.FnSplit(@CostCentre,','))

完整代码：

ALTER PROCEDURE [dbo].[SomeSP] 
   @CostCentre NVARCHAR(255)
AS 
   SELECT
      [ProjectCode],[ProjectName], [ProjectManager],SUM([Hours]) AS [Hours MTD]
   FROM dbo.Rpt_NRMA_CATS NC
   INNER JOIN PeriodID P ON NC.PeriodID = P.PeriodID
   WHERE 
      ([CostCentre]) collate database_default IN (SELECT Value FROM dbo.FnSplit(@CostCentre, ','))

Answer 2

只需将你的状况改为

即可

WHERE [Specifications].[EntityId] IN (select item from dbo.fnSplit(@EntityId))

fnSplit函数的代码是here

将多个值参数传递给存储过程
