Any of those help I want to use orderBY on several Columns, but they should act like one single column. The table looks something like that: , Try to add order column in select statement and then order by it.
code :
$qb = $em->createQueryBuilder();
$qb
    ->select('entity', 'COALESCE(col1, col2) as orderCol')
    ->from('Namespace/Entity', 'entity')
    ->orderBy('orderCol', 'DESC')
doctrine:
    orm:
      entity_managers:
        default:
          dql:
            string_functions:
              IF: DoctrineExtensions\Query\Mysql\IfElse 
$qb = $em->createQueryBuilder();
$qb
    ->select('entity', 'IF(col1, col1, col2) as orderCol')
    ->from('Namespace/Entity', 'entity')
    ->orderBy('orderCol', 'DESC')

Does that help In my symfony project, I have two entites Product.php and Configuration.php. , Try with this one :
code :
$qb->select('p')
   ->from('Product','p')
   ->leftJoin('p.configurations','c')
   ->having('COUNT(c.id) = 0') // check if the collection is empty
   ->groupBy('p.id');

With these it helps I have a large repository method wich generates a regular query at backend, some of the paramaters I pass to that repository method are the max-results, firs-result, order-by and order-by-dir in order to control the total of records to display, pagination and the order of the records. The problem is when I am in some configuration ex.(4th page, max-results:10, first-result:40), this should give me the 40th to 50th records of +1000 records in database but only is returning -10 records from +1000 records. , As from comments posting this as an answer

around this issue If you use ORM go with ORM one. Otherwise you should just use DBAL. Below you can find some details about what they actually do.
DBAL stands for Database Abstraction Layer. It tries to abstract as much of the database specific stuff like drivers or query syntax, so they can be interchangeable without the need for altering your code.
