A Simple COUNT
The count method returns the number of matching rows, rather than the rows themselves. Here is an example of a simple COUNT query:
// Select the table
$table = db('mytable');
// Query the database
$count = $table->count()
->where('user','=','Evan')
->execute();
You can use the total method to count all the rows in a table:
$count = $table->total();
