将SQL语句转换为mySQL存储过程

Question

我有一块SQL可以解决排行榜上高尔夫球手的排名问题.我是Spring的新手,我不认为我可以使用Spring JDBC执行此操作,因此我认为我需要将其转换为mySQL存储过程.

任何人都可以给我一些关于我需要转换的指示吗？简单地将CREATE PROCEDURE和param列表放在此处不起作用.

SET @rank = 1, @prev_val = NULL, @prev_rank = NULL;
SELECT rank FROM
(
 SELECT @rank := IF(@prev_val!=winnings,@prev_rank+1,@rank) AS rank
     , @prev_val := winnings AS winnings
     , @prev_rank := @rank AS prevRank
     , t.golferID
  FROM 
     (
        select g.golferID, sum(winnings) as winnings 
        from results r
        join resultDetails rd on r.resultID = rd.resultID
        join golfers g on rd.golferID = g.golferID
        where r.status = 'C' and r.compID = 1 
        group by golferID order by winnings desc
     ) AS t
) AS showRank WHERE golferID = 16

Answer 1

这将帮助您开始：

drop procedure if exists get_golfer_rank;

delimiter #

create procedure get_golfer_rank
(
p_golferID int unsigned
)
proc_main:begin

set @rank = 0;

select 
...
where golferID = p_golferID;

end proc_main #

delimiter ;


call get_golfer_rank(18);
