Question

I have two tables

activity

id | regionId | method |

and region

id | name |

activity stores several different method strings, the one I’m most interested in being ‘logout’

What I need is to find the region that is logged out the most. I currently have this:

SELECT MAX(regionId) FROM activity GROUP BY regionId WHERE method='logout'

I’m guessing I need a count in there somewhere, but this query is over my head. Also, I would like it to return region.name instead of activity.regionId

Thanks

Try this:

SELECT regionId, COUNT(method) AS count FROM activity WHERE method = 'logout' ORDER BY count DESC LIMIT 1;

If you need the name instead of the region ID, you could do this:

SELECT region.name, COUNT(activity.method) AS count FROM region, activity WHERE region.regionId = activity.regionId AND activity.method = 'logout' ORDER BY count DESC LIMIT 1;
