MySql查询图形数据组-按列中的数据筛选

我有两个要连接的表，
这是表1“日历”

这是表2“潜在客户”

我有这个疑问

SELECT calendar.datefield AS DATE, IFNULL( count( lead.insertDate ) , 0 ) AS task FROM lead RIGHT JOIN calendar ON ( DATE( lead.insertDate ) = calendar.datefield ) GROUP BY DATE LIMIT 30

它工作得很好，这是我得到的结果：

问题是我想通过

lead.lpid

过滤数据。 我尝试在查询“WHERE lead.lpid=x”的末尾添加，并在lead.lpid数据的查询调用的开头添加，如下所示：

SELECT lead.lpid, calendar.datefield AS DATE, 
        IFNULL( count( lead.insertDate ) , 0 ) AS task
        FROM lead 
        RIGHT JOIN calendar ON ( DATE( lead.insertDate ) = calendar.datefield ) 
        GROUP BY DATE LIMIT 30 WHERE lead.lpid =  9

但是我得到了这个错误

.....'WHERE lead.lpid =  9' at line 5 

我有点迷路了。 任何帮助都会很好

这是我的SQL FIDLE，我已经尝试过查询：

哪里出错了：

SELECT lead.lpid, calendar.datefield AS DATE, 
        IFNULL( count( lead.insertDate ) , 0 ) AS task
        FROM lead 
        RIGHT JOIN calendar ON ( DATE( lead.insertDate ) = calendar.datefield )
        WHERE lead.lpid =  9 
        GROUP BY DATE LIMIT 30 

注意：在分组之前必须在何处

根据需要新建查询：

SELECT lead.lpid, calendar.datefield AS DATE, 
        IFNULL( count( lead.insertDate ) , 0 ) AS task
        FROM lead 
        RIGHT JOIN calendar ON ( DATE( lead.insertDate ) = calendar.datefield )
        AND lead.lpid =  9 
        GROUP BY DATE LIMIT 30

联机使用sql Formatter:

很好，它完成了工作，但现在我只看到有数据的日期。是否有办法查看所有日期，包括包含零的行？就像我在问题中发布的结果一样？当然，有没有一种简单的方法可以保留包含“0”的日期，并保留条件？是否也需要计数为0的记录？如果提供sqlfiddlewow man，这将非常有用！这正是我需要的！因此，您在选择之后删除了对

lead.lpid

的调用？伟大的tnx！

SELECT lead.lpid, calendar.datefield AS DATE, 
        IFNULL( count( lead.insertDate ) , 0 ) AS task
        FROM lead 
        RIGHT JOIN calendar ON ( DATE( lead.insertDate ) = calendar.datefield ) 
        WHERE lead.lpid =  9 GROUP BY DATE LIMIT 30

SELECT lead.lpid,
       calendar.datefield AS DATE,
       IFNULL(count(lead.insertDate), 0) AS task
FROM lead
RIGHT JOIN calendar ON (DATE(lead.insertDate) = calendar.datefield)
GROUP BY DATE
HAVING lead.lpid = 9 LIMIT 30
