SQL Server query concat question

Hello all,

If I have 4 fields that are CustomerGroup1, CustomerGroup2, CustomerGroup3, CustomerGroup4.   I want to concat one string with a comma separator.   How do I do this so I don't have an extra comma at the end if for example 3 and 4 is null.

Give this a whirl..
SELECT 
   CustomerGroup1 + ', ' + 
   CustomerGroup2 + ', ' + 
   CASE WHEN COALESCE(CustomerGroup3, '') <> '' THEN CustomerGroup3 + ', ' END + 
   CASE WHEN COALESCE(CustomerGroup4, '') <> '' THEN CustomerGroup4 END
FROM YourTable
