@A1 VARCHAR(10),
@A2 VARCHAR(10),
@A3 INT
  begin try  
    begin tran 
   DECLARE youcurname CURSOR  FOR SELECT A1,A2,A3 FROM YOUTABLENAME
OPEN youcurname
fetch next from youcurname into @a1,@a2,@a3
while @@fetch_status<>-1
begin
--您要执行的操作写在这里
fetch next from youcurname into @a1,@a2,@a3
end
close youcurname
deallocate youcurname
COMMIT TRAN  
end try   
begin catch   
    ROLLBACK  
end catch
