MySQL count from one table while joining another - mysql

Question

I don't know if it's just been a long day or what, but I cannot figure out the query that I need to run here. We have two tables - One for leads generated and one for reports. The leads table has basic lead info, along with the Source (Campaign) of the lead. However, we need to know the number of leads that an ACCOUNT has received within a date range. Here is the relevant table structure:
client_leads:
id
source
date
client_reports:
account
campaign
date
The 'source' column contains the same values as the 'campaign' column. So, how would I achieve the following:
Say there are 10 leads in the leads table, each with the campaign that generated the lead. There are 10 accounts in the reports table, each with hundreds of campaigns. I need to list each account and how many leads it has in the leads table.
I just can't get the logic straight in my head. I've tried everything that I can think of and it's just not working out for me. If you need further explanation, let me know. I'm trying to describe the problem to the best of my ability.

Answer 1

SELECT cr.account, cr.campaign, cr.date, COUNT(cl.id) AS number_of_leads
FROM client_reports cr
LEFT JOIN client_leads cl
ON cl.source = cr.campaign
GROUP BY cl.source
