[SOLVED] Grouping data by time intervals to make graphs

Recommended Posts

Hi All,

 

does anyone know any efficient way to group mysql data into 'bins' of time interval? What i want is to show a profile over time of how many times someone's page has been visited. Each time someone visits, they get added to a mysql database. So it's basically a collection of timestamps.

 

I'd like to be able to say

January: 10

Feb: 12

March: 5

 

etc etc....

 

Would it be best as part of the mysql query? or does php have some magic up its sleeve?

 

Thanks all!

Probably best in mysql with COUNT and GROUP BY

 

Something like

SELECT YEAR(datefield) Y, MONTH(datefield) M, DAY(datefield) D, COUNT(*) Cnt FROM yourtable GROUP BY YEAR(datefield), MONTH(datefield), DAY(datefield)

GROUP BY sort the results of an aggregate function such as count into groups based on charactaristics of the results. In your case, a characteristic of a timestamp is the month. MySQL understands this and can sort by year, month, day, hour, minute, etc.

The query MatthewJ posted should work for what you are trying to accomplish.
