Can anyone explain the fetch logic to me?

Question

SQL

open @cursor
fetch FIRST from @cursor into @str_fetch
while @@FETCH_STATUS = 0
begin
....
fetch NEXT from @cursor into @str_fetch
end
close @cursor
and
open @cursor
fetch NEXT from @cursor into @str_fetch
while @@FETCH_STATUS = 0
begin
....
fetch NEXT from @cursor into @str_fetch
end
close @cursor
I can't understand the difference :(

Answer 1

If the cursor has not been fetched yet, I assume that fetch FIRST and fetch NEXT give the same result - they return the first record.
