Question

I have a requirement to concatenate values in different rows of my query based on Item ID.

For instance, I have the following rows of data.

GroupID LABEL   VALUE   UNIT
    1   Name    Henry   
    1   Guest   Manny   Guest
    1   Room    12  
    1   Milk    10      Quart
    1   Eggs    3       dozen
    2   Name    Mark    Supervisor
    2   Water   13      Litre
    2   Milk    3       Gallons
    2   Soap    12      bars

And as output, I want to get the following

ItemID     VALUE 

1          Name: Henry; Guest:Manny Guest; Room:12; Milk:10 Quart; Eggs: 3 dozen;

2          Name: Mark supervisor; Water: 13 litre; Milk: 3 Gallons; Soap: 12 bars;

How do I accomplish this please?

Answer 1

Please try:

SELECT DISTINCT a.GroupID AS ItemID,(
SELECT ISNULL(b.LABEL,'')+': '+ISNULL(b.VALUE,'')+' '+ISNULL(b.UNIT,'')+';' FROM TABLE b WHERE b.GroupID=a.GroupID
FOR XML PATH('')) AS [VALUE]
FROM TABLE a
