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

check out this code.
you will get the idea.....
Declare @Aliases Table
(
        [FirstName] varchar(50) not null,
        [LastName] varchar(50) not null,
        [Alias] varchar(100) not null
)

Insert @Aliases
Select 'Clark','Kent','Superman'
Union All
Select 'Clark','Kent','Kal-El'
Union All
Select 'Clark','Kent','Gangbuster'
Union All
Select 'Clark','Kent','Supernova'
Union All
Select 'Clark','Kent','Nightwing'
Union All
Select 'Peter','Parker','Spiderman'
Union all
Select 'Peter','Parker','WebSligner'

Select * from @Aliases

Select Distinct
        [LastName],
        [FirstName],
        (Stuff((Select ', ' + Alias From @Aliases T2 Where T2.FirstName = T1.FirstName and T2.LastName = T2.LastName FOR XML PATH('')),1,2,'')) as Aliases
From @Aliases T1
Order By [LastName], [FirstName]

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
