I have 1 table with a unique reference and 1 line per unique reference (code)
I have another table with multiple records (somewhere between zero and 10) with the same code (unique reference in the first table).
I want to bring in the multiple records from the 2nd table into the 1st table, but I want to bring them in in one column separated by a comma and space
Example below


1st table
code      person      Qty      Time           Clothes
                        
11111      Steve      1      10:00      
22222      Ray              2      11:00      
33333      Alex         3      12:00      

2nd table
code      clothes
      
11111      Hat
11111      Coat
33333      Hat
33333      Coat
33333      Gloves
      

1st table after stored procedure
code      person      Qty      Time       Clothes
                        
11111      Steve      1      10:00      Hat, Coat
22222      Ray         2      11:00      
33333      Alex              3      12:00      Hat, Coat, Gloves

Can anyone offer some advice?

Thanks

        [LastName] varchar(50) not null,
        [Alias] varchar(100) not null

Hi IT-Misfit,
First let us know why it is required to bring the records from the second table into a single column in the first table, because we may then be able to advise on a better approach than this.

Thanks

Try this code
Raj
SELECT DISTINCT A.code, person, Qty, Time
, Stuff((Select ', ' + clothes From YourTable2 Where code = A.code FOR XML PATH('')),1,2,'')
FROM YourTable1 A
	INNER JOIN YourTable2 B ON A.code = B.code
