问题描述
在MySQL中排名时,我需要一些有关关系的帮助.例如:
I need some help dealing with ties when ranking in MySQL. For example:
PLAYER |要点
PLAYER | POINTS
- 玛丽:90
- 鲍勃:90
- Jim:65
- 凯文:12
鲍勃和玛丽都应该排名第一.吉姆应该是第三名.凯文应该是#4.
Bob and Mary should both be ranked #1. Jim should be #3. Kevin should be #4.
MySQL:
SET @rank=0;
SELECT @rank:=@rank +1 as rank, player, points FROM my_table
如何更改SELECT语句,以便在平局时排名正确?
How can I change the SELECT statement so that the ranking is correct in the case of ties?
我的现实生活中的问题更加复杂,但是如果我了解如何解决上述问题,那我应该定下来.
My real life problem is more complicated, but if I understand how to solve the above, then I should be set.
