sql - Test on @@FETCH_STATUS deletes other variables -


im using scroll cursor on table username , other information on each row. need detect change of user know information point can sent 1 user, point another...

it works fine when have 1 user in table:

user1|something1|something1 user1|something2|something2 user1|something3|something3

i need detect end, did this:

declare @cr cursor scroll select etc... fetch first cr ... while @@fetch_status=0 begin ... collect data /*here problem*/ fetch next ... /* collected data cursor here still exists (lets call them @data)*/    if @@fetch_status=-1 begin        -- here @data = null    end end

i dont understand why is. in words, need know last line before gone. thank you

while loop fine. concatenating varchar null blame. varchar big mssms show in result or messages windows.
