Hello,

 I want to count and select multiple items in a table.

 I want to select members who opened more than 15 threads in the last 15 days.

 Threadid - userid - dateline are the column names.


How can i select and list these userids?

This will do:

SELECT *, COUNT(*) as num_threads FROM `table` WHERE  DATE_SUB(CURDATE(),INTERVAL 15 DAY) <= dateline  GROUP BY `userid` HAVING num_threads > 15 ORDER BY aantal DESC

Open in new window


I'm not sure what kind of value you have in dateline but let me know if this doens't work so you can give me some more detail on that field.
