How do I group a date field to get quarterly results in MySQL?

Question

I have a job table that holds jobs and leaddate is the field for the job entry.

The result I want to get is the number of jobs I have in each quarter. My query count

Answer 1

I think this should do the job:

SELECT YEAR(leaddate) AS year, QUARTER(leaddate) AS quarter, COUNT(jobid) AS jobcount
  FROM jobs
 WHERE contactid = '19249'
 GROUP BY YEAR(leaddate), QUARTER(leaddate)
 ORDER BY YEAR(leaddate), QUARTER(leaddate)
