I have a Jobs and a Companies table, and I want to extract 20 jobs that meet the following criteria:
- Jobs only from two (2) named companies
- There can at most be 10 jobs per company
I have tried the following SELECT with UNION DISTINCT, but the problem is that the LIMIT 0,10 applies to the whole result set. I want it to apply to each of the companies.
If there aren’t 10 jobs per company, then the query should return all the jobs it finds.
SELECT c.name, j.title, j.`desc`, j.link FROM jobs_job j INNER JOIN companies_company c ON j.company_id = c.id WHERE c.name IN ('Company1') UNION DISTINCT SELECT c.name, j.title, j.`desc`, j.link FROM jobs_job j INNER JOIN companies_company c ON j.company_id = c.id WHERE c.name IN ('Company2') ORDER by name, title LIMIT 0,10
I am new to MySQL, so realise there may be a smarter way to do this instead of with UNION, so any suggestions for improvements are definitely welcome.
