写的存储过程有语法错误

--存储过程InquiryT0
create proc InquiryTO(@StartStop varchar(32),@EndStop varchar(32))
as
begin
     select
          sr1.Stop as 起始站点，
          sr2.Stop as 目的站点，
          sr1.[Route] as 乘坐线路，
          sr2.Position-sr1.Position as 经过的站点数
     from
         stop_route sr1,
         stop_route sr2
     where
         sr1.[Route]=sr2.[Route]
         and sr1.Position<sr2.Position
         and sr1.Stop=@StarStop
         and sr2.Stop=@EndStop
end  

错误原因是：消息 102，级别 15，状态 1，过程 InquiryTO，第 5 行
'，' 附近有语法错误。
