Mysql 一个表中两个表的信息

我有这两张桌子，它们是这样布置的

表1

+------+----------+-----+--------+
| Year |  Runner  | Age | Result |
+------+----------+-----+--------+
| 2004 | Runner 1 |   3 | Won    |
| 2004 | Runner 2 |   4 | Lost   |
| 2004 | Runner 3 |   3 | Lost   |
| 2005 | Runner 1 |   3 | Lost   |
| 2005 | Runner 2 |   3 | Lost   |
| 2005 | Runner 3 |   4 | Won    |
| 2006 | Runner 1 |   4 | Won    |
| 2006 | Runner 2 |   3 | Lost   |
| 2006 | Runner 3 |   4 | Lost   |
+------+----------+-----+--------+

表2

+-------+----------+-----+
| RCNum |  Runner  | Age |
+-------+----------+-----+
|     1 | Runner 1 |   3 |
|     2 | Runner 2 |   4 |
|     3 | Runner 3 |   3 |
|     4 | Runner 4 |   3 |
|     5 | Runner 5 |   3 |
+-------+----------+-----+

现在我将使用

    $numbers = mysql_query("SELECT age,
        sum(case when result <> ''then 1 else 0 end) Sec1Picks,
        sum(case when result = 'Won' then 1 else 0 end) Sec1Wins
    FROM table1
    GROUP BY age
    ORDER BY age ASC");

while($row = mysql_fetch_array($numbers, MYSQL_ASSOC)) {
echo "(".$row['Age']."yo) ".$row['Sec1Wins']."-".$row['Sec1Picks']; }

但是，对于插入到rcnums列中的每个数字，它将在Picks/Wins列中再次添加统计信息

在Picks/Wins列中，我只想在表1中计算3yo是60和2，而不是420和14。如何更改编码以实现此目的？

选择t2.age
SELECT t2.age
     , SUM(CASE WHEN t1.result <> '' THEN 1 ELSE 0 END) Sec1Picks
     , SUM(CASE WHEN t1.result = 'Won' THEN 1 ELSE 0 END) Sec1Wins
     , GROUP_CONCAT(DISTINCT t2.rcnum ORDER BY rcnum SEPARATOR ' ') rcnums
  FROM table2 t2
  LEFT
  JOIN table1 t1
    ON t1.runner = t2.runner
 GROUP 
    BY t2.age;

，求和（t1.result“”时为1，其他0结束时为1）秒1分
，SUM（当t1.result='Won'然后1或0结束时的情况）Sec1Wins
，组_CONCAT（按rcnum分隔符“”的不同t2.rcnum顺序）rcnums
来自表2 t2
左边
加入表1 t1
在t1.runner=t2.runner上
团体
t2.5岁；

很抱歉，这些表在不同的数据库中吗？标题是这样说的，但在你的问题中没有明确说明。对于不同的数据库，我假设不同的数据库instances@Leo我想OP的意思是“桌子”是的，对不起，我的意思是，两张桌子合二为一。我注意到有些东西现在不太适合它！假设我正在查看3yo跑步者的数据，数据为1-5。。对于每个RCNum，这是重复的，所以如果RCNum列中有4个，那么这个数字将更改为4-20，而我希望它保持为1-5，不管怎样，修复这个问题？
