Question

I have a table called Rule_X_ListType in the following structure

Rue_ID  ListType_ID  Value
---------------------------
1       2            319
1       2            400
1       5            8150
1       5            1000
1       3            10211
2       2            400
2       6            10211
3       7            10211
3       3            8051
2       2            319

If I will give the input as Rule_ID = 1 and ListType_ID = 2, then I need the output as a string with values :

319,400

Anybody please help out…Thanks in advance…

I do not feel the neccessity for either the CTE or the FOR XML PATH.
This can be accomplished using the much more simple method of COALESCE

DECLARE @List varchar(100)

SELECT 
   @List = COALESCE(@List + ', ', '') + CAST(Value AS varchar(10))
FROM 
   Rule_X_ListType
WHERE 
   Rule_ID = 1 and ListType_ID = 2

SELECT @List
