[英]How do I make three columns combine ordered by the number of goals?
I'm having some problems with unifying two tables in SQL.我在统一 SQL 中的两个表时遇到了一些问题。 I want to get the players that scored more goals in the season, but I cannot get it right.我想得到本赛季进球更多的球员,但我做不到。
I've done both things separate ways:我已经以不同的方式完成了这两件事:
SELECT name, surname
FROM players
GROUP BY name, surname
If I do this I get all the names from the players, but if I mix it with the other on a JOIN ON some players disappear with no apparent reason.如果我这样做,我会从玩家那里得到所有的名字,但是如果我在 JOIN ON 上将它与另一个混在一起,一些玩家会无缘无故地消失。
RESULT:结果:
| name | surname |
| John | Brown |
| Robert | Smith |
| Albert | Carpenter |
| David | Addams |
| Richard | McAvoy |
Then I have the number of goals that each one scored, I get this by doing a COUNT(*)然后我有每个人的进球数,我通过 COUNT(*) 得到这个
SELECT COUNT(*) AS goals
FROM goals
JOIN players ON (players.id = goals.player_id)
GROUP BY player_id
ORDER BY goals DESC
LIMIT 5;
Down in this bit I can get the desired results as well, which are the 5 highest scores in goals.在这一点上,我也可以获得预期的结果,即进球得分最高的 5 个。 But I don't know how to get a combined result.但我不知道如何获得综合结果。
RESULT:结果:
| goals |
| 152 |
| 140 |
| 102 |
| 95 |
| 91 |
I want my columns to be:我希望我的专栏是:
| Name | Surname | goals |
| John | Brown | 152 |
| Robert | Smith | 140 |
| Albert | Carpenter | 102 |
| David | Addams | 95 |
| Richard | McAvoy | 91 |
Any help is appreciated.任何帮助表示赞赏。 :) :)
Try this尝试这个
SELECT p.name, p.surname, g.goals
FROM goals g
INNER JOIN players p ON p.id = g.player_id
ORDER BY g.goals DESC LIMIT 5;
Better if you show some records from both table, then it will be easier to answer.如果您显示两个表中的一些记录会更好,那么它会更容易回答。 Now I'm assuming your goal table is like this playerid -> no.现在我假设你的目标表就像这个 playerid -> 不。 of goals目标
SELECT name, surname, COUNT(*) AS goals SELECT name, surname, COUNT(*) AS 目标
FROM goals从目标
inner JOIN players ON (players.id = goals.player_id)内部加入玩家开启(players.id = goal.player_id)
GROUP name, surname组名,姓氏
ORDER BY goals DESC按目标排序 DESC
LIMIT 5;限制 5;
