SQL Summarise entires into one line

Posted on 2014-12-15
Last Modified: 2014-12-15
Hi All,

I have a table with ID and Invoice_Number. Multiple invoices per ID. I want to group by ID and have Invoice_Numbers as a comma seperated line against the ID.


1    101
1    102
1    103
2    201
2    202


1    101, 102, 103
2    201, 202

Can someone point me in the rough direction?

Use FOR XML PATH(). E.g.

DECLARE @Sample TABLE ( ID INT, Payload INT )
VALUES  ( 1, 101 ),
        ( 1, 102 ),
        ( 1, 103 ),
        ( 2, 201 ),
        ( 2, 202 );

        STUFF(( SELECT  ', ' + CAST(I.Payload AS VARCHAR(255))
                FROM    @Sample I
                WHERE   I.ID = O.ID 
				FOR XML PATH('')
              ), 1, 2, '')
FROM    @Sample O

Great, nearly there.

It is however cutting off the very first digit of the concatenated column.

So instead I'm getting:

1   abc
1   123
2   123
2   abc

1   bc, 123
2   23, abc
