Question

好吧，我遇到了问题。

我有大约5个数据库表。一个表格包含广告系列列表，另一个表格包含广告组列表，另一个表格包含广告列表，另一个表格包含点击次数列表，另一个表格包含潜在客户列表，另一个表格包含潜在客户状态列表。每个表还有其他列。例如，点击中包含ad_id和列帐户，并且潜在客户状态表具有潜在客户ID，买方和金额。每个表都有一个id与另一个表id相关联的列。

所以我试图将我的数据变成以下格式

campaign   keyword   count(keyword)   sum(amount)   buyer
bing-auto  rap        15                45           david
google-auto honda     10                30           chris

基本上，它是按关键字和广告系列分组的每个成功线索。

但是，我似乎无法解决这个问题。

SELECT keyword, COUNT(keyword) FROM in_clicks AS ic
       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;
       INNER JOIN lead_status AS ls ON l.id = ls.id
       INNER JOIN leads AS l ON ic.in_click_id = l.id  
WHERE ic.create_date LIKE '%2011-08-19%' AND ic.location NOT LIKE '%Littleton%'
GROUP BY ic.keyword ORDER BY COUNT(ic.keyword) DESC

我知道这不是一个好的解释，我上面的查询并不好，但我有点坚持如何继续。任何人都可以帮助我指出正确的方向。

编辑：这是表格架构。

这样的东西？

SELECT 
  c.name as campaign
  , ic.keyword
  , count(ic.keyword) as keycount
  , sum(ls.amount) as total_amount
  , group_concat(ls.buyer) as buyers
FROM in_click ic 
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)
INNER JOIN lead_status AS ls ON (l.id = ls.id)
INNER JOIN leads AS l ON (ic.in_click_id = l.id)
WHERE ic.create_date BETWEEN 2011-08-01 and 2011-08-31
      AND ic.location NOT LIKE 'test%'
GROUP BY ic.keyword
ORDER BY keycount

<强>说明
不要将LIKE用于日期字段，请使用BETWEEN startdate AND enddate 如果您使用LIKE %....，则无法使用索引尝试并使用LIKE cghxgs%，这样您就可以使用索引如果需要进行索引文本匹配，请使用带有MATCH AGAINST语法的全文索引这只适用于MyISAM表....
