Using PHP and MySQL, I want to query a table of postings my users have made to find the person who has posted the most entries.
What would be the correct query for this?
Sample table structure:
[id] [UserID] 1 johnnietheblack 2 johnnietheblack 3 dannyrottenegg 4 marywhite 5 marywhite 6 johnnietheblack
I would like to see that "johnnietheblack" is the top poster, "marywhite" is second to best, and "dannyrottenegg" has the least
SELECT COUNT(*) AS `Rows`, UserID FROM `postings` GROUP BY UserID ORDER BY `Rows` DESC LIMIT 1
This gets the number of rows posted by a particular ID, then sorts though the count to find the highest value, outputting it, and the ID of the person. You'll need to replace the 'UserID' and 'postings' with the appropriate column and field though.
