为什么我的数据集显示第一个查询的列但不显示其他查询的列？

Question

为什么我的.xsd数据集显示1个查询的列而不显示其他2个查询？

我在我的存储过程中使用了3个查询，并在我的数据集中用于RDLC报告，但它确实只显示第一个查询的列而不显示其他查询。

我的SP：

create PROC  [dbo].[SelectContractorsBio]

    @GC_ID INT

AS
BEGIN    



                   Select c.Name, c.FatherName, c.Farm, cat.Name 'Cat', c.CNIC, c.EnlistmentNo, c.ContactNo,
                   CONVERT(date,c.RegistrationDate,106) as RegistrationDate, c.Email, pcat.Name 'PECCat', c.PECCategoryNo 'PECLicenseNo',
                   c.PECReceiptNo, c.ExpectedDate, c.CNWEnlistmentNo, c.NTN, cr.BankName, cr.BankCode, cr.BankDraftNo, 
                   cat.Fee, cat.Amount, c.Address, Case when c.HasTaxExempted = 1 then 'Yes' else 'No' end
                   from Contractors c
                   Inner Join Category cat
                   ON Cat.ID= c.ContractorType_ID
                   Inner Join ContractorRenewal cr
                   ON cr.Contractor_ID= c.ContractorID
                   Inner Join PecCategories pcat
                   ON pcat.ID= c.PECCategoryID


                   Select Documents.DocumentID, Documents.Name from DocumentContractor dc
                   Inner Join Documents
                   ON Documents.DocumentID= dc.Doc_ID
                   where dc.Contractor_ID= @GC_ID

                   Select sc.SpecializationID, sc.Name 'SpecializationName', sc.SpecializationCode, spc.Contractor_ID from SpecializationCodes sc
                   INNER JOIN SpecializationCodeContractor spc
                   ON sc.SpecializationID= spc.SP_ID


END

存储过程不能输出多个结果集，因此您只能从第一个查询中获得结果。

如果您需要来自所有查询的数据，则需要将其整合到一个查询...

<!-- language: lang-sql -->

      ,c.FatherName
      ,c.Farm
