while len(@S) > 0
begin
  --print left(@S, charindex(',', @S+',')-1)

Problem

How to loop through comma separated list in SQL? I have a list of ID's and I need to pass these ID's to a stored procedure. I CANNOT alter the stored procedure. I need to figure out how to execute the SP for each id. Give me some ideas, I can carry on from there. Thanks.
