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

you can use the Quarter function to get a quarter from date:

select count(jobid) as jobcount, QUARTER(leaddate) as qt, YEAR(leaddate) as year
from jobs
where contactid='19249'
group by year,qt
