CrossTab View?

In my SQL DB I have a table 'tblInstallPay_TaxAuthorities'.  The pertinent fields in the table are 'InstallPayHdrID' (Int) and 'Parcel' nvarchar(30).

A given InstallPayHDrID may appear multiple times.  For a given InstallPayHdrID a Parcel may appear mulltiple times.

'ID'     'Parcel'
123    Parcel1
123   Parcel2
123   Parcel1
123   Parcel3


I have reporting requirement to list all of the Parcels associated with an InstallPayHdrID on one line.

So if InstallPayHdrID 123 has 3 parcels associated it would show as
123     Parcel1 Parcel2  Parcel3

My initial plan was to write a routine reading a view that groups the InstallPayHDrID and Parcels.

For each ID I would lop thru building a sting of the associated parcels.

I'm wondering if there is a way to create a view that will do this for me.  Each returned line in the view would have two fields.
1 The InstallPayHDrID
2. A string of all the parcels associated with that InstallPayHdrID, with each Parcel only being listed once.

Can it be done?  If not I'll just go back to my looping routine.

To pull this off you can mimic the T-SQL code in the article T-SQL:  Normalized data to a single comma delineated string and back, top section, replacing all the table and column names to match your situation, and replacing the comma with a single space.

I strongly suggest using an inline-table-valued function for best performance and ease of use, which you use a CROSS APPLY to invoke when needed  For example:

SET ANSI_NULLS ON;
SET QUOTED_IDENTIFIER ON;
GO
CREATE FUNCTION dbo.Get_InstallPay_Parcel_List
(
    @ID int
)
RETURNS TABLE
AS
RETURN (
    SELECT '' + Parcel AS Parcel_List
    FROM (
        SELECT DISTINCT Parcel
        FROM dbo.tblInstallPay_TaxAuthorities
        WHERE ID = @ID
    ) AS derived
    ORDER BY Parcel
    FOR XML PATH('')
);
GO

--then to use the function:
SELECT mt.*, gipl.Parcel_List
FROM dbo.main_table mt
CROSS APPLY dbo.Get_InstallPay_Parcel_List (mt.ID) gipl
GO
