Question

我有两张桌子，我想连接，
这是表1＆＃34;日历＆＃34;

这是表2＆＃34;主要＆＃34;

我有这个查询

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

效果很好，这是我得到的结果：

问题是我想按lead.lpid过滤数据。我试图在查询结尾添加＆＃39; WHERE lead.lpid = x＆＃39;并在查询的开头添加lead.lpid数据，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

但我收到此错误

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

我很善良，很遗憾。任何帮助都会很棒！

这是我的SQL小提琴，我尝试过查询：SQLFiddle

Answer 1

错误的地方：

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：必须在GROUP BY

之前

您想要的新查询：

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

Answer 2

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
