    <p>If look at the <a href="http://docs.doctrine-project.org/projects/doctrine-orm/en/latest/reference/annotations-reference.html#annref-joincolumn" rel="nofollow">documentation</a> of <code>@JoinColumn</code></p> <p><em>This annotation is <strong>used in the context of relations in @ManyToOne, @OneToOne fields</strong> and <strong>in the Context of @JoinTable nested inside a @ManyToMany</strong>. This annotation is not required. If its not specified the attributes name and referencedColumnName are inferred from the table and primary key names.</em></p> <p>So as you are using <code>ManyToOne</code> relation your relation definition would be,</p> <pre><code>/** * @var Users * * @ORM\ManyToOne(targetEntity="Users") * @ORM\JoinColumn(name="useridx", referencedColumnName="idx") */ private $useridx; </code></pre> <p><b>Edit: </b></p> <p>If you want to get datas from user side then you have to create <a href="http://docs.doctrine-project.org/projects/doctrine-orm/en/latest/reference/association-mapping.html#one-to-many-bidirectional" rel="nofollow">OneToMany</a> relation. e.g</p> <p>In Datas.php</p> <pre><code>/** * @var Users * * @ORM\ManyToOne(targetEntity="Users", inversedBy = "datas") * @ORM\JoinColumn(name="useridx", referencedColumnName="idx") */ private $useridx; </code></pre> <p>And in Users.php add following line,</p> <pre><code>/** * @ORM\OneToMany(targetEntity="Datas", mappedBy="useridx", cascade={"persist"}) */ protected $datas; </code></pre> <p>And then do a <code>doctrine:generate:entities</code> command. To do operations on relation check <a href="http://docs.doctrine-project.org/projects/doctrine-orm/en/latest/reference/working-with-associations.html" rel="nofollow">this</a> doc entry.</p>

    1. COThanks for the reply. I already did this (as you can see in my Datas.php). The fact is i have to fetch two tables in one select. To be more clear, when i get User from Users table i want to also fetch Datas that related to this user (lets say useridx = 1). In your example (which is same as with mine) i only get User 1 from Users table. I had to fetch Datas table at the same time using $user->getDatas()->getPhrase();

    3. CO`$user->getDatas()` returns a [Collection](http://www.doctrine-project.org/api/common/2.2/class-Doctrine.Common.Collections.Collection.html) object. You have to iterate through the collection to get phrases of each collection

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
