Convert SQL query to Ruby help

I need to query my database table to find which employee has the most support tickets related to them. I can do this just fine using this MySQL query开发者_运维问答:

SELECT employee_id, COUNT(id) AS number_of_tickets FROM tickets GROUP BY employee_id ORDER BY number_of_tickets DESC LIMIT 1;

How would write this in Ruby-on-Rails?

Thanks very much for your assistance.

I use Ruby version 1.8.6, Rails version 2.2.2 and MySQL Server version 5.0.

Try this:

Ticket.find(:all, :select => 'employee_id, count(id) as number_of_tickets',
            :group => 'employee_id' , :order => "number_of_tickets Desc", :limit => 1 )

Or directly use:

Ticket.find_by_sql('select...... ' )
