SQL Server 2016 - Stuff / XML Path

Question

我有这个基本查询，带回配置信息。每张MatrixCellID都是一张单独的票，每张票可以有多个StatisticalGroupCodes和StatisicalGroupDescriptions。目前每个MatrixCellID出现多次，因为它有多个StatisicalGroupCodes。我希望代码和描述列在一列中以逗号分隔显示。

这是我的查询：

select
  cmc.MatrixSheetId,
  CMS.MatrixSheetName,
  cmc.MatrixCellId,
  CMC.Price,
  CMC.PriceListId,
  CPL.PriceListName,
  CPT.Description as PriceTable,
  case when CMC.Code <> '' then cmc.code else 'EMPTY' end AS TicketCode,
  case when CMC.Name <> '' then cmc.name else 'EMPTY' END AS TicketName,
  case when CMC.Description <> '' then cmc.description else 'EMPTY' END AS TicketDescription,
  case when CMC.Description2 <> '' then cmc.description2 else 'EMPTY' end  AS AdditionalTicketDescription,
  CASE WHEN CMCI.AccountMandatory = 1 THEN 'YES' else 'NO' end AS AccountMandatory,
  CASE WHEN CDC.Description IS NULL THEN 'NONE' ELSE CDC.Description END  AS AccountCategory,
  CDT.DocTemplateName AS PrintTemplate,
  CTP.Description as TaxPackage,
  CT.TaxName,
  CASE when CMC.PriceType = 0 then 'Fixed' else 'Variable' end as PriceType,
  CCC.CostCenterDescription,
  CCC.CostCenterCode,
  CCC.CostCenterAK,
  CSG.StatisticalGroupCode,
  CSG.StatisticalGroupDescription
from
 CNF_MatrixCell CMC
 inner join CNF_MatrixSheet CMS on CMC.MatrixSheetId = CMS.MatrixSheetId
 inner join CNF_PriceList CPL on CMC.PriceListId = CPL.PriceListId
 INNER JOIN CNF_MatrixCellInfo CMCI on CMC.MatrixCellId = CMCI.MatrixCellId
 left join CNF_DmgCategory CDC on CMCI.AccountDmgCatId = CDC.DmgCategoryId
 left join CNF_DocTemplate CDT on CMC.DocTemplateId = CDT.DocTemplateId
 LEFT join CNF_TaxPackage CTP on CMC.TaxPackageId = CTP.TaxPackageId
 LEFT join CNF_Tax2Package CT2P on CTP.TaxPackageId = CT2P.TaxPackageId
 LEFT JOIN CNF_Tax CT on CT2P.TaxId = CT.TaxId
 LEFT JOIN CNF_CostCenter_Validity CCCV on CMC.MatrixCellId = cccv.MatrixCellId
 LEFT JOIN CNF_CostCenter CCC on CCCV.CostCenterId = CCC.CostCenterId
 inner join CNF_PriceTable CPT on CMC.PriceTableId = CPT.PriceTableId
 LEFT JOIN CNF_StatisticalGroupValidity CSGV on CMC.MatrixCellId = CSGV.MatrixCellId
 LEFT JOIN CNF_StatisticalGroup CSG on CSGV.StatisticalGroupId = CSG.StatisticalGroupId
WHERE CMC.Enabled = 1
  AND CCC.Enabled = 1
  AND CPT.Enabled = 1
  AND CMS.Enabled = 1
ORDER BY
  CMS.MatrixSheetId,
  CMC.MatrixCellId,
  CMC.Code

我曾尝试使用Stuff和XML Path，但无法使用我的连接正常工作。先感谢您。

你可以用它。

select
    cmc.MatrixSheetId,
    CMS.MatrixSheetName,
