Question

Ok so I don’t think the question is as simple as the title suggests but here goes …
I have this query:

SELECT age.*, job.id FROM age, job WHERE ((age.aid = job.id) AND (age.aid='$id'))

this basically joins the two tables age and job and gets matching rows

but now I need to find the most common age stored in row guess under the table age

DB layout

Table: age

rows: aid – guess

Table: job

Rows: id

From what I have found searching I need to use count()

eg:

SELECT guess, COUNT(guess) AS countguess FROM age GROUP BY guess ORDER BY countguess DESC LIMIT 1

but how can I merge the 2 queries together?

Answer 1

You could do something like this

SELECT age.aid, job.id, age.guess, COUNT(age.guess) AS countguess 
FROM age, job 
WHERE ((age.aid = job.id) AND (age.aid='$id')) 
GROUP BY guess 
ORDER BY countguess DESC
