如何在SQL中建立一对多关系？我有一个查询，它打印给定的输出：https://www.screencast.com/t/II0h2YXRi。现在我已经完成了想要打印具有相同值的Name列的操作。

DECLARE @agv NVARCHAR(max);

DECLARE @Con NVARCHAR(max);

SET @agv = '';

SET @Con = '';

SELECT DISTINCT dbo.bsContract.ContractNumber,Advertiser.OrganizationName AS Advertiser,
       JobName AS Campaign,bsContract.FromDate AS StartDate,
       Advertiser.OrganizationName AS Client,
      (ISNULL(cli.FirstName, '') + ' '  + cli.LastName) AS ClientRep,
       c.OrganizationName AS Vendor,
      (ISNULL(con.FirstName, '') + ' '  + con.LastName) AS 'VendorRep' 

FROM dbo.bsDocument

INNER JOIN Opportunity ON bsDocument.OpportunityID = Opportunity.OpportunityID

INNER JOIN Organization AS Advertiser ON Advertiser.OrganizationID = Opportunity.OrganizationID

INNER JOIN Contact AS UploadContact ON UploadContact.ContactID = bsDocument.UploadedBy

LEFT JOIN Organization ON bsDocument.OrganizationID = Organization.OrganizationID

LEFT JOIN dbo.bsContractLineItemV2 ON bsContractLineItemV2.ContractNumber = bsDocument.ModuleID 
          AND bsContractLineItemV2.VendorOrgID = bsDocument.OrganizationID 

LEFT JOIN dbo.bsContract ON bsContract.ContractNumber = bsDocument.ModuleID

LEFT JOIN Contact AS CompanyDocContact ON CompanyDocContact.ContactID = bsContractLineItemV2.VendorContactID

INNER JOIN dbo.Organization AS c ON c.OrganizationID = dbo.bsContractLineItemV2.VendorOrgID

LEFT JOIN dbo.Contact AS con ON VendorContactID = con.ContactID

LEFT JOIN dbo.Contact AS cli ON bsContract.ContactID = cli.ContactID

WHERE  MONTH(bsContract.FromDate) = 3 AND YEAR(bsContract.FromDate) = 2019 
       AND Advertiser.OrganizationName LIKE '%'+@agv+'%' 
       AND bsContract.ContractNumber LIKE '%'+@Con+'%'

这不是您可以或应该在SQL中执行的操作。如果您具有处理查询结果集并将其输出到文件的代码，则可以在其中进行处理。或者，在导出到Excel之后，您可以应用条件格式来实现外观，如下所述：https://stackoverflow.com/a/9174254/3250365。
