Question

I am coding a social network and I need a way to list the most used trends, All statuses are stored in a content field, so what it is exactly that I need to do is match hashtag mentions such as: #trend1 #trend2 #anothertrend

And sort by them, Is there a way I can do this with MySQL? Or would I have to do this only with PHP?

Thanks in advance

Answer 1

I think it is better to store tags in dedicated table and then perform queries on it.
So if you have a following table layout

trend | date

You’ll be able to get trends using following query:

SELECT COUNT(*), trend FROM `trends` WHERE `date` = '2012-05-10' GROUP BY trend

18  test2
7   test3
