Question

I have a mysql database with the schema with fields

username, timestamp

where timestamp is the date of last activity.

I would like to construct a query in mysql that will give me the number of records, broken up by month, for a specific user.

Thanks.

You’re question is posted as number of users per month, but I think you mean number of records per month from a given user. The query you want is:

Select CAST(CONCAT(YEAR(`timestamp`),'-',MONTH(`timestamp)) AS CHAR) as `month`, COUNT(*) as `hits` FROM db.table WHERE `username`='<the_username>'  GROUP BY `month`;
