Joining together five tables
Allright, I am stuck on a problem.
I have about 5 database tables. One table has a list of campaigns, another has a list of ad groups, another has a list of ads, another has a list of in clicks, another has a list of leads, and another has a list of lead status. Each table also has other columns. For example, in clicks has an ad_id and column account, and the lead status table has a lead id, buyer, and amount. Each table a column with an id associated with another table id.
So I'm trying to get my data into the following format
campaign keyword count(keyword) sum(amount) buyer
bing-auto rap 15 45 david
google-auto honda 10 30 chris
Basically, it's every successful lead grouped by keyword and campaign.
However, I just can't seem to solve th开发者_高级运维is problem.
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
I know this is not a good explanation, and my above query is not good, but I'm a little stuck on how to proceed. Can anyone help point me in the right direction.
EDIT: Here's the table schema.
CAMPAIGN
id name trafficsource createdate
20 hip hop bing 2001-08-16
21 rap bing 2001-08-18
AD GROUPS
id name campaignid createdate
15 jayz 20 2001-08-16
16 eminem 21 2001-08-18
ADS
id headline adgroupid
13 cool is cool 15
14 wow, great 16
IN CLICKS
id keyword adid createdate
205 his name 13 2001-08-16
206 whoa 14 2001-08-18
LEADS
id in_click_id create_date
300 205 2001-08-16
301 206 2001-08-18
LEAD STATUS
id lead_id success amount buyer
501 300 0 5 jack
502 300 1 15 jill
Something like this?
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
Remarks
Don't use LIKE
for datefields, use BETWEEN startdate AND enddate
.
If you use LIKE %....
you will not be able to use an index.
Try and use LIKE cghxgs%
, that way you will be able to use an index.
If you need to do index text matches, use full text indexes with the MATCH AGAINST
syntax.
This will only work on MyISAM tables however....
