在sql server中关于游标cursor的使用

--此处使用pubs库
declare @myname varchar(50)
declare @fname varchar(20)
declare @lname varchar(20)
declare my_cursor cursor for
select fname,lname from employee order by emp_id
open my_cursor
fetch next from my_cursor into @fname,@lname
while @@fetch_status=0
begin
    set @myname=@fname+@lname
    fetch next from my_cursor into @fname,@lname
end
close my_cursor
deallocate my_cursor
