making subquery or query like mysql jointure

Thursday 22 September 2016 5:36:21 pm

I spend my time since a begin this projet on ez to find the right and goods tutorials and good documentations for eZ5...Now as I success to render a bundle controler where I want in my pagelayout template.
Now I would like to make a query and a subquery to 2 differents content-type one I call categories and second content_category. The second is linking to categories or to another content_category normaly I other framework I could usually make a join and a recursive request in Mysql how doing that with eZplatform framework ?!
In normal case I use Msql command join and I could have the array I need. But with eZplatform is it possible to make a fake of this kind of jointure ??? For the moment I success to make 2 query first one to get catgories and second to get category_content and is id content_categories id but have trouble in my template to render the id I get. I'm tired and boring explore all forum about Ez where we don't know if is specific answer for eZ4 or eZ5... 
There is anyone who could explain me how to do a 2 query with a join between two content type or to tell how to construct a good eZrender array content from my own array result to give to my controler template and have in twig template a good eZrender field...????
thanks to all
