我有两张桌子:
players
id | dni | name
-----------------
1 222 mike
2 333 gerard
3 444 mark
4 555 alfred
5 666 thomas
5 777 nicolas
teams
id | dni1 | dni2 | cat
------------------------
1 222 333 1
2 444 555 1
3 666 333 2
4 777 222 2
我想要的是根据猫做一个选择语句。所以
cat = 1应该是:
迈克杰拉德 mark alfred并且对于cat = 2应该是:
托马斯杰拉德 尼古拉斯迈克编辑使其更难,玩家表有一个新的colum = points
players
id | dni | name | points
--------------------------
1 222 mike 1
2 333 gerard 2
3 444 mark 3
4 555 alfred 4
5 666 thomas 5
5 777 nicolas 6
现在结果给出了两个玩家的积分和最大总数的顺序之和。 cat = 1应该是:
mark alfred 7
迈克杰拉德3
答案 0 :(得分:0)
select t.cat, p1.name name1, p2.name name2, p1.points + p2.points points
from teams AS t
join players AS p1 ON p1.dni = t.dni1
join players AS p2 on p2.dni = t.dni2
where cat = 1
order by points desc
