I am learning from this Question but facing issues with many operations in between:

doctrine 2 query builder and join tables

Below is my Questions. I am looking for help in my previous question too.. Thanks for those who helped me in solving the issues.

I am creating a big Query in Doctrine 2.3, The operations are not familiar to me.But I learnt with the help of many persons. Currently I am facing issue with Inner Joint between 3 tables.

My Joint:

SELECT *
FROM user AS u
LEFT JOIN source AS s ON u.user_source_fk=s.source_id
LEFT JOIN area AS a ON s.source_node_fk = a.area_id;

The above Query is what I am trying to convert in Doctrine.

I tried to give the query as like this but it is not working:

SELECT a FROM Ipf\Model\User u LEFT JOIN Ipf\Model\Sources ON u.user_source_fk=s.source_id LEFT JOIN Ipf\Model\Area aa ON s.source_node_fk = aa.area_id;

How My Original Query will be:

1 Doctrine JOIN Query:

SELECT *
FROM user AS u
LEFT JOIN source AS s ON u.user_source_fk=s.source_id
LEFT JOIN area AS a ON s.source_node_fk = a.area_id;

SELECT * FROM user WHERE 
(`user_name` like '%TOM%' OR `user_name` like '%AN%' and `login_datetime` BETWEEN '2013-01-01 00:00:00' and '2013-02-31 23:59:59') OR
NOT ( --NOR
   (`user_name` like '%PHP%' OR `user_name` like '%BA%' and `login_datetime` BETWEEN '2013-02-01 00:00:00' and '2013-03-31 23:59:59') OR
   (`user_name` like '%SUN%' OR `user_name` like '%MOON%' and `login_datetime` BETWEEN '2013-03-01 00:00:00' and '2013-04-31 23:59:59')
) OR
NOT ( --NAND
   (`user_name` like '%RAJ%' OR `user_name` like '%MUTH%' and `login_datetime` BETWEEN '2013-04-01 00:00:00' and '2013-06-31 23:59:59') AND
   (`user_name` like '%BAG%' OR `user_name` like '%LAP%' and `login_datetime` BETWEEN '2013-05-01 00:00:00' and '2013-07-31 23:59:59')
)

I want to do Inner Joint to the Query with the above Query that is Inner Joint with Operators Refer:Multiple Query in Doctrine with NAND,NOR,NOT,AND Operators

How to Join the tables and execute the Query?

2 Doctrine Query Generation:

$qry = $this->manager()->createQueryBuilder()
        ->from($this->entity, 'e')
        ->select('e');


// (`user_name` like '%TOM%' OR `user_name` like '%AN%' and `login_datetime` BETWEEN '2013-01-01 00:00:00' and '2013-02-31 23:59:59')
$expr1 = $qry->expr()->andX(
    $qry->expr()->orX(
       $qry->expr()->like('e.user_name', '%TOM%'), 
       $qry->expr()->like('e.user_name', '%AN%')
    ),
    $qry->expr()->between('e.login_datetime', '2013-02-01 00:00:00', '2013-02-31 23:59:59')
);

//(`user_name` like '%PHP%' OR `user_name` like '%BA%' and `login_datetime` BETWEEN '2013-02-01 00:00:00' and '2013-03-31 23:59:59')

$expr2a = $qry->expr()->andX(
    $qry->expr()->orX(
       $qry->expr()->like('e.user_name', '%PHP%'), 
       $qry->expr()->like('e.user_name', '%BA%')
    ),
    $qry->expr()->between('e.login_datetime', ''2013-02-01 00:00:00'', '2013-03-31 23:59:59')
);

// (`user_name` like '%SUN%' OR `user_name` like '%MOON%' and `login_datetime` BETWEEN '2013-03-01 00:00:00' and '2013-04-31 23:59:59')
$expr2b = $qry->expr()->andX(
    $qry->expr()->orX(
       $qry->expr()->like('e.user_name', '%SUN%'), 
       $qry->expr()->like('e.user_name', '%MOON%')
    ),
    $qry->expr()->between('e.login_datetime', '2013-03-01 00:00:00', '2013-04-31 23:59:59')
);

// combine expr2a and expr2b with OR as $expr2

$expr2 = $qry->expr()->orX($expr2a, $expr2b);


// (`user_name` like '%RAJ%' OR `user_name` like '%MUTH%' and `login_datetime` BETWEEN '2013-04-01 00:00:00' and '2013-06-31 23:59:59')

$expr3a = $qry->expr()->andX(
    $qry->expr()->orX(
       $qry->expr()->like('e.user_name', '%RAJ%'), 
       $qry->expr()->like('e.user_name', '%MUTH%')
    ),
    $qry->expr()->between('e.login_datetime', ''2013-04-01 00:00:00'', '2013-06-31 23:59:59')
);

// (`user_name` like '%BAG%' OR `user_name` like '%LAP%' and `login_datetime` BETWEEN '2013-05-01 00:00:00' and '2013-07-31 23:59:59')
$expr3b = $qry->expr()->andX(
    $qry->expr()->orX(
       $qry->expr()->like('e.user_name', '%BAG%'), 
       $qry->expr()->like('e.user_name', '%LAP%')
    ),
    $qry->expr()->between('e.login_datetime', '2013-05-01 00:00:00', '2013-07-31 23:59:59')
);

// combine expr2a and expr2b with OR as $expr2

$expr3 = $qry->expr()->andX($expr3a, $expr3b);


// final query essentially WHERE expr1 OR NOT(expr2) OR NOT(expr3)
$qry->where($expr1)
    ->or($qry->expr()->not($expr2))
    ->or($qry->expr()->not($expr3));

How can I Modify to Achieve the Above Query with JOIN Operation?

Can some one help me to solve my issue. Its nightmare for me in doctrine....

The complex part of you query is actually the WHERE so you should be able to just add the joins with little issue.

$qry = $this->manager()->createQueryBuilder()
        ->select(array('e', 's', 'a'))
        ->from($this->entity, 'e')
        ->leftJoin('e.sources', 's')
        ->leftJoin('s.node', 'a');

And then you would do the rest of your query logic as is pretty much.

The one thing that needs to be mentioned is that in DQL you are dealing with Entities and their properties as opposed to tables and columns.

So in my example e.sources needs to be the mapped property name for the UserSource entity/collection on your User entity. Likewise, s.node needs to be the mapped property name of the Area entity/collection on UserSource.
