Question

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.

Answer 1

declare @S varchar(20)
set @S = '1,2,3,4,5'

while len(@S) > 0
begin
  --print left(@S, charindex(',', @S+',')-1)
  exec YourSP left(@S, charindex(',', @S+',')-1)
  set @S = stuff(@S, 1, charindex(',', @S+','), '')
end
