Question

Is there any solution to find number of values Grouped by MySQL groupby query. Following is my Query.
$groupBy = 'PropertyViewer.ip_address';
$this->paginate = array("group"=>array($groupBy),"order"=>array("PropertyViewer.id desc"));

I need to find how many values grouped in each case.

Answer 1

I think all you need is the COUNT() aggregate function in your SELECT query:

SELECT COUNT( ip_address) as num_values
     FROM PropertyViewer
GROUP BY PropertyViewer.ip_address
ORDER BY PropertyViewer.id desc
