Re: SQL Cartesian Product with CakePHP find
Yes, you can use union in cake 3, paginating union queries is tricky as the different databases will interpret the ORDER BY and LIMIT differently. Waht you need to to in that case is passing a select * form (all union queries) to the paginator and it will work.

Re: SQL Cartesian Product with CakePHP find
I would do a raw query, as Cake 2 does not support using derived table queries. You can use Cake 3, though.
