Question

下午好，

我希望在以下查询中找到总列的总和：

SELECT * 
FROM  `btb_picks` 
WHERE  `player_name` =  'bryan'
ORDER BY  `total` 
LIMIT 0 , 3

该表共有9条记录，其中player_name =＆＃39; bryan＆＃39;

Position Golfer Name    Round 1 Round 2 Round 3 Round 4 Today   Through Total   Player Name
T4       Lee Westwood   67      12:25   -       -       -5      F       -5      bryan
T4       Justin Rose    67      1:39    -       -       -5      F       -5      bryan
T4       Sergio Garcia  67      1:49    -       -       -5      F       -5      bryan

我想收集这3条记录的总数（-15）之和

当我运行以下查询时：

SELECT SUM( total ) AS 3_man
FROM  `btb_picks` 
WHERE  `player_name` =  'bryan'
ORDER BY total
LIMIT 0 , 3

它返回：

3_man -13

这是整个总列的总和，而不是我有兴趣找到总数的3条记录。

当我以这种方式尝试查询时：

SELECT * FROM `btb_picks` WHERE `player_name` in ( SELECT * 
    FROM  `btb_picks` 
    WHERE  `player_name` =  'bryan'
    ORDER BY  `total` 
    LIMIT 0 , 3 );

SQL咆哮：

1235 - 这个版本的MySQL还没有支持＆＃39; LIMIT＆amp; IN / ALL / ANY / SOME子查询＆＃39;

如何获得这三个记录的总和？

Answer 1

试试这个......

SELECT SUM(s.score) FROM
(SELECT total as score FROM btb_picks WHERE player_name = 'bryan' ORDER BY total LIMIT 0,3) s

SQL Sum函数限制0,3返回整列的总和
