在MySql查询中连接3个表

我在MySql数据库中有这3个表

users
+----+------+--------+------+
| Id | Name | Status | Role |
+----+------+--------+------+
|  1 | A    | Aktiv  | Op   |
|  2 | B    | Aktiv  | Op   |
|  3 | C    | Aktiv  | Op   |
|  4 | D    | Aktiv  | Op   |
+----+------+--------+------+

cnt
+----+------+------------+------+
| Id | Name | Date       | Type |
+----+------+------------+------+
|  1 | A    | 2017-11-09 | Web  |
|  2 | B    | 2017-11-09 | Web  |
|  3 | C    | 2017-11-09 | Web  |
|  4 | C    | 2017-11-09 | Inb  |
|  5 | A    | 2017-11-09 | Web  |
+----+------+------------+------+

Lead
+----+------+------------------+------------+
| Id | Name | Date             | Type       |
+----+------+------------------+------------+
|  1 | A    | 2017-11-09 00:24 | Imported   |
|  2 | B    | 2017-11-09 09:32 | Activation |
|  3 | B    | 2017-11-09 10:56 | Activation |
|  4 | D    | 2017-11-09 12:21 | Activation |
|  5 | D    | 2017-11-10 12:22 | Activation |
+----+------+------------------+------------+

我试图将它们加入主表，但没有成功，我使用的查询是：

SELECT IFNULL(u.Name,'Total') as "Name",
Sum(IF(c.Type = 'Web',1,0)) as "Cnt Web",
Sum(IF(l.Type = 'Activation',1,0)) as "Lead Web"
FROM users u
LEFT JOIN cnt c ON u.Name = c.Name and c.Date = '2017-11-09'
LEFT JOIN lead l ON u.Name = l.Name and l.Date>= '2017-11-09' AND l.Date< '2017-11-10'
WHERE u.Status = 'Aktiv' AND u.Role = 'Op'
GROUP BY u.Name WITH ROLLUP

当我尝试将第一个表与第二个表或第一个表与第三个表联接时，我得到了正确的结果，但当我将它们全部联接时，却无法得到所需的结果

任何答案都是最受欢迎的。先谢谢你

这里有一个使用相关子查询的解决方案

SELECT  u.Id,
        u.Name,
        (SELECT COUNT(Name) FROM cnt WHERE Name = u.name AND type = 'Web' AND Date = '2017-11-09') AS cnt_web,
        (SELECT COUNT(Name) FROM lead WHERE Name = u.name AND type = 'Activation' AND Date>= '2017-11-09' AND Date< '2017-11-10') AS cnt_lead
FROM    users u
WHERE   u.Status = 'Aktiv' AND u.Role = 'Op'

为什么Lead web的ID为4的值为1可能是重复的，因为D的Lead表中有两条记录，所以它不应该是2吗？@SEarle1986，因为一条记录在2017-11-09，另一条记录在2017-11-10，我只需要2017-11-09中的记录，正如我在上面的slq代码中解释的。好的，现在更新的答案它在1.0613秒内工作，我把卷轴弄丢了。无论如何，非常感谢

SELECT  u.Id,
        u.Name,
        (SELECT COUNT(Name) FROM cnt WHERE Name = u.name AND type = 'Web' AND Date = '2017-11-09') AS cnt_web,
        (SELECT COUNT(Name) FROM lead WHERE Name = u.name AND type = 'Activation' AND Date>= '2017-11-09' AND Date< '2017-11-10') AS cnt_lead
FROM    users u
WHERE   u.Status = 'Aktiv' AND u.Role = 'Op'
