Question

我正在处理SSRS报告，该报告使用包含一些参数的存储过程。

我遇到问题的一个参数是因为我可以选择多个项目（guid值），并且它们超过了4000个逗号分隔值。

存储过程：proc_GetCompanyRecord

========================================

CREATE PROCEDURE [dbo].[proc_GetCompanyRecord]
    (
    @Year AS VARCHAR(MAX) = NULL,
    @CoreCompanyId AS VARCHAR(MAX) = NULL,
    @CompanyId AS VARCHAR(MAX) = NULL,
    @OwnerId VARCHAR(MAX) = NULL
    )

--THE REST OF MY QUERY HERE WHICH PULLS ALL OF THE NEEDED COLUMNS

WHERE CoreCompany.CoreCompanyId in (SELECT * FROM ufnSplit (@CoreCompanyId, ','))
AND Company.CompanyId in (SELECT * FROM ufnSplit (@CompanyId, ','))

========================================

功能：[dbo]。[ufnSplit]

CREATE FUNCTION [dbo].[ufnSplit]
(
    @RepParam varchar(MAX),
    @Delim char(1)
)
RETURNS @Values TABLE (Item UNIQUEIDENTIFIER)
AS
BEGIN
  DECLARE @chrind INT
  DECLARE @Piece varchar(MAX)
  SELECT @chrind = 1 
  WHILE @chrind > 0
    BEGIN
      SELECT @chrind = CHARINDEX(@Delim,@RepParam)
      IF @chrind  > 0
        SELECT @Piece = LEFT(@RepParam,@chrind - 1)
      ELSE
        SELECT @Piece = @RepParam
      INSERT  @Values(Item) VALUES(@Piece)
      SELECT @RepParam = RIGHT(@RepParam,LEN(@RepParam) - @chrind)
      IF LEN(@RepParam) = 0 BREAK
    END
  RETURN
  END

当我尝试通过向@CompanyId参数提供4000+值来运行存储过程时，它可以正常工作并返回所有可能的记录。

但是我在CRM中部署报告后，运行它并点击查看报告，它显示以下错误，“发生了错误”

我对它进行了诊断，发现4000多个guid逗号对于存储过程和IN语句来说太过分了：

消息8152，级别16，状态10，行7字符串或二进制数据将是截断。

请帮忙！

进行@CompanyID参数查询时。添加“全选”选项。

SELECT 'Select All' AS CompanyID, 1 as myOrder
 UNION
 Select CAST(CompanyID AS VARCHAR), 2 as myOrder
 FROM CompanyTable
 ORDER BY myOrder

有了这个，用户不必选择所有4000个值，只需选择“全选”选项，它就会为它们选择所有内容。并更新您的proc_getCompanyRecord以处理CompanyID的新“全选”值。

CREATE PROCEDURE [dbo].[proc_GetCompanyRecord]
    (
    @Year AS VARCHAR(MAX) = NULL,
    @CoreCompanyId AS VARCHAR(MAX) = NULL,
    @CompanyId AS VARCHAR(MAX) = NULL,
    @OwnerId VARCHAR(MAX) = NULL
    )

--THE REST OF MY QUERY HERE WHICH PULLS ALL OF THE NEEDED COLUMNS

WHERE CoreCompany.CoreCompanyId in (SELECT * FROM ufnSplit (@CoreCompanyId, ','))
AND (Company.CompanyId in (SELECT * FROM ufnSplit (@CompanyId, ',')) OR Company.CompanyID = 'Select All')

使用存储过程的SSRS多值参数具有太多值
