SQL Server 2016 - Stuff/XML Path - sql

Question

I have this basic query, bringing back configuration information. Each MatrixCellID is an individual ticket, and each can have multiple StatisticalGroupCodes and StatisicalGroupDescriptions. Currently each MatrixCellID appears multiple times because of its multiple StatisicalGroupCodes. I would like the Code and Description columns to show all in one column, comma separated.
This is my query:
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
I have tried to use Stuff and XML Path, but cannot get it work correctly with my joins.
Thank you in advance.

You can use this.
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,
