Question

我遇到了一些mysql查询问题。我正在尝试将多个表连接在一起。在一个表中，我有一个成功的在线客户列表，在另一个表中，我有一个表，其中包含来自它的流量来源。我正在尝试跟踪哪些客户来自某个广告。因此，我想查询某个特定日期和特定广告系列中的新客户。

SELECT keyword, COUNT(keyword) FROM in_clicks AS ic WHERE ic.create_date LIKE '%2011-08-19%' GROUP BY ic.keyword ORDER BY COUNT(ic.keyword) DESC
       INNER JOIN leads AS l ON ls.lead_id = l.id 
       INNER JOIN lead_status AS ls ON ls.lead_id = ls.id
       INNER JOIN ads AS a ON ic.ad_id = a.id
       INNER JOIN ad_groups AS ag ON a.ad_group_id = ag.id
       INNER JOIN campaigns AS c ON ag.campaign_id = c.id;

我运行上面的代码并得到以下错误。

Error Code: 1064
'INNER JOIN leads AS l ON ls.lead_id = l.id Innner Join lead_status AS ls' at line 2

Answer 1

这应该更好： - ）。

SELECT keyword, COUNT(keyword) 
FROM in_clicks AS ic 
       INNER JOIN leads AS l ON ls.lead_id = l.id 
       INNER JOIN lead_status AS ls ON ls.lead_id = ls.id
       INNER JOIN ads AS a ON ic.ad_id = a.id
       INNER JOIN ad_groups AS ag ON a.ad_group_id = ag.id
       INNER JOIN campaigns AS c ON ag.campaign_id = c.id;
WHERE ic.create_date LIKE '%2011-08-19%' 
GROUP BY ic.keyword 
ORDER BY COUNT(ic.keyword) DESC

顺序是：SELECT .. FROM ... JOIN ... WHERE ... GROUP BY .. HAVING .. ORDER BY .. LIMIT

Answer 2

所有INNER JOIN条款都必须在FROM和WHERE条款之间。在同一查询中使用INNER JOIN之后的WHERE语法无效。

正如波希米亚人指出的那样，你也有一个语法错误：Innner应该是INNER（你有一个到多个n个字符。）
