doctrine: many to many relation with join table: how to add WHERE condition

I have three tables:

Clients: (id, name, ...)

Files: (id, filename, type, data)

and join table:

Clients2Files (id, id_clients, id_files, created_at, deleted_at)

in php class Clients I want to get access to all client's files, but only to the files that hasn't been deleted (in sql speak WHERE deleted_at IS NULL)

Now I have code like this (in entity class Client), which selects all (even deleted) files:

/**                                                                         
* @ManyToMany(targetEntity="File")                                          
* @JoinTable(name="Clients2Files",                                  
*      joinColumns={@JoinColumn(name="id_clients", referencedColumnName="id")},
*      inverseJoinColumns={@JoinColumn(name="id_files", referencedColumnName="id")}
*      )                                                                    
*/                                                                          
private $files;

How can I add condition WHERE deleted_at IS NULL to this doctrine code? To select only files that are not "deleted".

The annotations you added don't actually "SELECT" anything. All they do is tell Doctrine about your objects and their relations. What you want to do is:

$qb = $em->createQueryBuilder();
$qb->select('clients, files')
   ->from('Clients', 'clients')
   ->join('c.files', 'files')
   ->where('files.deleted_at IS NULL');

If you find yourself doing this often, and are using Doctrine 2.2+, you can take a look at filters: http://docs.doctrine-project.org/projects/doctrine-orm/en/latest/reference/filters.html
