&lt;p&gt;The &lt;a href=&quot;QSqlRelationalTableModel.html#QSqlRelationalTableModel(com.trolltech.qt.core.QObject, com.trolltech.qt.sql.QSqlDatabase)&quot;&gt;&lt;tt&gt;QSqlRelationalTableModel&lt;/tt&gt;&lt;/a&gt; class provides an editable data model for a single database table, with foreign key support.&lt;/p&gt;
&lt;p&gt;&lt;a href=&quot;QSqlRelationalTableModel.html#QSqlRelationalTableModel(com.trolltech.qt.core.QObject, com.trolltech.qt.sql.QSqlDatabase)&quot;&gt;&lt;tt&gt;QSqlRelationalTableModel&lt;/tt&gt;&lt;/a&gt; acts like &lt;a href=&quot;QSqlTableModel.html#QSqlTableModel(com.trolltech.qt.core.QObject, com.trolltech.qt.sql.QSqlDatabase)&quot;&gt;&lt;tt&gt;QSqlTableModel&lt;/tt&gt;&lt;/a&gt;, but allows columns to be set as foreign keys into other database tables.&lt;/p&gt;
&lt;p&gt;&lt;table align=&quot;center&quot; cellpadding=&quot;2&quot; cellspacing=&quot;1&quot; border=&quot;0&quot;&gt;
&lt;tr valign=&quot;top&quot; class=&quot;odd&quot;&gt;&lt;td&gt;&lt;img src=&quot;%2E%2E/images/noforeignkeys.png&quot; /&gt;&lt;/td&gt;&lt;td&gt;&lt;img src=&quot;%2E%2E/images/foreignkeys.png&quot; /&gt;&lt;/td&gt;&lt;/tr&gt;
&lt;/table&gt;&lt;/p&gt;
&lt;p&gt;The screenshot on the left shows a plain &lt;a href=&quot;QSqlTableModel.html#QSqlTableModel(com.trolltech.qt.core.QObject, com.trolltech.qt.sql.QSqlDatabase)&quot;&gt;&lt;tt&gt;QSqlTableModel&lt;/tt&gt;&lt;/a&gt; in a &lt;a href=&quot;%2E%2E/gui/QTableView.html&quot;&gt;&lt;tt&gt;QTableView&lt;/tt&gt;&lt;/a&gt;. Foreign keys (&lt;tt&gt;city&lt;/tt&gt; and &lt;tt&gt;country&lt;/tt&gt;) aren't resolved to human-readable values. The screenshot on the right shows a &lt;a href=&quot;QSqlRelationalTableModel.html#QSqlRelationalTableModel(com.trolltech.qt.core.QObject, com.trolltech.qt.sql.QSqlDatabase)&quot;&gt;&lt;tt&gt;QSqlRelationalTableModel&lt;/tt&gt;&lt;/a&gt;, with foreign keys resolved into human-readable text strings.&lt;/p&gt;
&lt;p&gt;The following code snippet shows how the &lt;a href=&quot;QSqlRelationalTableModel.html#QSqlRelationalTableModel(com.trolltech.qt.core.QObject, com.trolltech.qt.sql.QSqlDatabase)&quot;&gt;&lt;tt&gt;QSqlRelationalTableModel&lt;/tt&gt;&lt;/a&gt; was set up:&lt;/p&gt;
&lt;pre&gt;        model-&amp;gt;setTable(&amp;quot;employee&amp;quot;);

        model-&amp;gt;setRelation(2, QSqlRelation(&amp;quot;city&amp;quot;, &amp;quot;id&amp;quot;, &amp;quot;name&amp;quot;));
        model-&amp;gt;setRelation(3, QSqlRelation(&amp;quot;country&amp;quot;, &amp;quot;id&amp;quot;, &amp;quot;name&amp;quot;));&lt;/pre&gt;
&lt;p&gt;The &lt;a href=&quot;QSqlRelationalTableModel.html#setRelation(int, com.trolltech.qt.sql.QSqlRelation)&quot;&gt;&lt;tt&gt;setRelation&lt;/tt&gt;&lt;/a&gt; function calls establish a relationship between two tables. The first call specifies that column 2 in table &lt;tt&gt;employee&lt;/tt&gt; is a foreign key that maps with field &lt;tt&gt;id&lt;/tt&gt; of table &lt;tt&gt;city&lt;/tt&gt;, and that the view should present the &lt;tt&gt;city&lt;/tt&gt;'s &lt;tt&gt;name&lt;/tt&gt; field to the user. The second call does something similar with column 3.&lt;/p&gt;
&lt;p&gt;If you use a read-write &lt;a href=&quot;QSqlRelationalTableModel.html#QSqlRelationalTableModel(com.trolltech.qt.core.QObject, com.trolltech.qt.sql.QSqlDatabase)&quot;&gt;&lt;tt&gt;QSqlRelationalTableModel&lt;/tt&gt;&lt;/a&gt;, you probably want to use QSqlRelationalDelegate on the view. Unlike the default delegate, QSqlRelationalDelegate provides a combobox for fields that are foreign keys into other tables. To use the class, simply call QAbstractItemView::setItemDelegate() on the view with an instance of QSqlRelationalDelegate:&lt;/p&gt;
&lt;pre&gt;        QTableView *view = new QTableView;
        view-&amp;gt;setModel(model);
        view-&amp;gt;setItemDelegate(new QSqlRelationalDelegate(view));&lt;/pre&gt;
&lt;p&gt;The sql/relationaltablemodel&lt;/tt&gt; example illustrates how to use &lt;a href=&quot;QSqlRelationalTableModel.html#QSqlRelationalTableModel(com.trolltech.qt.core.QObject, com.trolltech.qt.sql.QSqlDatabase)&quot;&gt;&lt;tt&gt;QSqlRelationalTableModel&lt;/tt&gt;&lt;/a&gt; in conjunction with QSqlRelationalDelegate to provide tables with foreigh key support.&lt;/p&gt;
&lt;p align=&quot;center&quot;&gt;&lt;img src=&quot;%2E%2E/images/relationaltable.png&quot; /&gt;&lt;/p&gt;&lt;p&gt;Notes:&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;The table must have a primary key declared.&lt;/li&gt;
&lt;li&gt;The table's primary key may not contain a relation to another table.&lt;/li&gt;
&lt;li&gt;If a relational table contains keys that refer to non-existent rows in the referenced table, the rows containing the invalid keys will not be exposed through the model. The user or the database is responsible for keeping referential integrity.&lt;/li&gt;
&lt;/ul&gt;
