Question

I have the following script:

SELECT left(SHI.FSOKEY, 6) AS [SoNo]
,      substring(SHI.FSOKEY, 7, 3) AS [So Item]
,      right(SHI.FSOKEY, 3) AS [So Rels]
,      QAL.FCLOT AS [LotSerial]

FROM shmast SHM
     INNER JOIN shitem SHI
     ON SHM.FSHIPNO = SHI.FSHIPNO
     INNER JOIN qalotc QAL
     ON SHM.FSHIPNO = Left(QAL.FCUSEINDOC, 6)
        AND substring(QAL.FCUSEINDOC, 7, 6) = SHI.FITEMNO

This produces output that looks like this:

SoNo      So Item  SoRels  LotSerial
123456      1      001     ABCD
123456      1      001     AMOH
123456      1      001     POWK
123456      1      001     IUIL
123456      1      002     ABCE

I want to group by SoNo, SoItem, SoRels and get a list of LotSerials for each. So, my output would look like this:

SoNo      So Item  SoRels  LotSerial
123456      1      001     ABCD, AMOH, POWK, IUIL
123456      1      002     ABCE

I need to do so that I can pull this information back into a main query based on the SoNo, SoItem, SoRels.

Any help would be greatly appreciated.

@cmsjr beat me to it with his answer which is just bout the same. I do build the string differently, and have a complete working example.

try this:

CREATE TABLE YourTable  (SoNo int, SoItem int, SoRels char(3),  LotSerial char(4))
go
INSERT INTO YourTable VALUES (123456,1,'001','ABCD')
INSERT INTO YourTable VALUES (123456,1,'001','AMOH')
INSERT INTO YourTable VALUES (123456,1,'001','POWK')
INSERT INTO YourTable VALUES (123456,1,'001','IUIL')
INSERT INTO YourTable VALUES (123456,1,'002','ABCE')
go
CREATE FUNCTION LotSerial_to_CVS(@SoNo int, @SoItem int, @SoRels char(3))
RETURNS varchar(2000) AS
BEGIN
    DECLARE @cvs varchar(2000)
    SELECT @cvs=ISNULL(@cvs+', ','')+LotSerial
        FROM YourTable
        WHERE SoNo=@SoNo AND SoItem=@SoItem AND SoRels=@SoRels
    RETURN @cvs
END
go

SELECT
    SoNo, SoItem, SoRels, dbo.LotSerial_to_CVS(SoNo, SoItem, SoRels)
    FROM YourTable
        GROUP BY SoNo, SoItem, SoRels

OUTPUT:

SoNo        SoItem      SoRels 
----------- ----------- ------ -----------------------
123456      1           001    ABCD, AMOH, POWK, IUIL
123456      1           002    ABCE
