Question

I’m having a terrible time trying to figure out how to add XML PATH to my code to concatenate some information, let alone understanding how XML PATH works. I’ve spent the better part of the last two days working on this and would appreciate some help!!

Here’s the code I’m working with:

Select Top 100 Percent Agreements.AgrmntID, Agreements.Description As
  AgrmntDesc, Agreements.Status, AgreementSchedules.SchedDate, DateName(dw,
  AgreementSchedules.SchedDate), LaborCodeTypes.Description As LaborCode,
  Customers.CustName, Customers.CompanyName, JobSites.SiteName,
  AgreementSchedules.AgrmntSchedID
From Agreements Inner Join
  AgreementTypes On Agreements.AgrmntTypeID = AgreementTypes.AgrmntTypeID
  Inner Join
  AgreementSchedules On Agreements.AgrmntID = AgreementSchedules.AgrmntID
  Inner Join
  Customers On Agreements.CustID = Customers.CustID Inner Join
  JobSites On Agreements.CustSiteID = JobSites.CustSiteID Left Outer Join
  LaborCodeTypes On AgreementSchedules.RepairID = LaborCodeTypes.RepairID
Where Agreements.Status = 2 And Month(AgreementSchedules.SchedDate) =
  Month(GetDate())

Sample Data:

| AgreementID | LaborCodeTypes.Description   | DateName(dw, AgreementSchedules.SchedDate)|
| - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -|
| 1           | Landscaping                  | Tuesday                                   |
| 1           | Landscaping                  | Friday                                    |
| 1           | Sweeping                     | Monday                                    |
| 1           | Sweeping                     | Wednesday                                 |
| 1           | Sweeping                     | Friday                                    |
| 2           | Landscaping                  | Monday                                    |

Expected Output:

| AgreementID | LaborCode   | Days Of Week              |
| - - - - - - - - - - - - - - - - - - - - - - - - - - - |
| 1           | Landscaping | Tuesday, Friday           |
| 1           | Sweeping    | Monday, Wednesday, Friday |
| 2           | Landscaping | Monday                    |

I would greatly, greatly appreciate it if someone could help me.

Thank you in advance!!

;with C as
(
  select A.AgreementID,
         LCT.Description as LaborCode,
         Ags.ShedDate
  from Agreements as A
    inner join AgreementSchedules as AgS
      on A.AgreementID = AgS.AgreementID
    inner join LaborCodeTypes as LCT
      on AgS.RepairID = LCT.RepairID
  where A.[Status] = 2 and
        AgS.ShedDate >= dateadd(month, datediff(month, 0, getdate()), 0) and
        AgS.ShedDate < dateadd(month, 1+datediff(month, 0, getdate()), 0)
)
select C1.AgreementID,
       C1.LaborCode,
       stuff((select ', '+datename(weekday, C2.ShedDate)
              from C as C2
              where C1.AgreementID = C2.AgreementID and
                    C1.LaborCode = C2.LaborCode
              order by C2.ShedDate
              for xml path(''), type).value('.', 'varchar(max)'), 1, 2, '') as [Days Of Week]
from C as C1
group by C1.AgreementID, C1.LaborCode;
