I have the attached and SP code snippet which, when fed a VCHRNMBR variable, will return up to 4 rows.  I need to design a WHILE Loop to combine the DistRef field from all the returned records and concatenate them in one field, delimited by a comma.  I am new to working with WHILE loops, how would I go about this?
SELECT coalesce(pm1.DistRef+',','')+ pm1.DistRef as 'TEXT'
from PM20000 pm2
join PM10100 pm1 ON pm2.VCHRNMBR=pm1.VCHRNMBR
where @VCHRNMBR = pm2.VCHRNMBR

This is in an SP I created to get all the values from a query and put them in one string and return that string:

This will return a comma delimited string of all the values that the select query has in it.

This is basically the full stored procedure minus the create and the return portions.

If you have any questions let me know.
Begin
	SELECT @OUTPUT = @OUTPUT + case when @OUTPUT = '' then '' else ', '  end + rtrim(T1.SelectField)		
	FROM Table1 T1 INNER JOIN
	Table2 T2 ON T1.Key = T2.Key 
	WHERE (T2.lookUpfield = @VariablePassedToSQ) 	
	Group by T1.SelectField
	Order by T1.SelectField
    End

Brad:

I think this is going to do the trick, just two issues

1.  The SP wants input for the @output paramter.  How to I make the SP look for only the ID parameter.

2.  When i feed the SP a valid ID, i get the following error:
Syntax error converting the nvarchar value 'i.libhart, AP' to a column of data type int.  

when i feed 'test' to the @output parameter and the other two are valid

For #1 the "Output" paramater is just the variable that is set up to hold the string of data that is being generated and that is going to be returned from the stored procedure.

For #2 it sounds like you are passing a text value to the SP but in the SP itself the variable is declared as an int and it does not like that.
