    <p>Depending on the concrete code <code>typeid</code> returns different things. Additionally <code>name()</code> can return anything (including making the first letter uppercase or removing *), it is only for debuging. Now I have a few different posible answers what <code>typeid(animal).name()</code> can return.</p> <p>Version 1 <code>animal</code> is a class name:</p> <pre><code>struct animal { virtual ~animal() {} }; struct dog : animal {}; struct cat : animal {}; struct bird : animal {}; int main() { std::cout &lt;&lt; typeid(animal).name() &lt;&lt; std::endl; // animal return 0; } </code></pre> <p>Version 2 <code>animal</code> is a typedef to <code>Animal</code>:</p> <pre><code>struct Animal { }; struct Dog : Animal {}; struct Cat : Animal {}; struct Bird : Animal {}; int main() { typedef Animal animal; std::cout &lt;&lt; typeid(animal).name() &lt;&lt; std::endl; // Animal return 0; } </code></pre> <p>Vesion 3 <code>animal</code> is a pointer:</p> <pre><code>struct Animal { }; struct Dog : Animal {}; struct Cat : Animal {}; struct Bird : Animal {}; int main() { Dog d; Animal* animal=&amp;d; std::cout &lt;&lt; typeid(animal).name() &lt;&lt; std::endl; // Animal* return 0; } </code></pre> <p>Version 4 <code>animal</code> is a object:</p> <pre><code>struct Animal { }; struct Dog : Animal {}; struct Cat : Animal {}; struct Bird : Animal {}; int main() { Animal animal; std::cout &lt;&lt; typeid(animal).name() &lt;&lt; std::endl; // Animal return 0; } </code></pre> <p>Version 6 <code>animal</code> is a reference to a <strong>non polymorphic</strong> objcet:</p> <pre><code>struct Animal { }; struct Dog : Animal {}; struct Cat : Animal {}; struct Bird : Animal {}; int main() { Dog d; Animal&amp; animal=d; std::cout &lt;&lt; typeid(animal).name() &lt;&lt; std::endl; // Animal return 0; } </code></pre> <p>and version 7 <code>animal</code> is a reference to a <strong>polymorphic</strong> object:</p> <pre><code>struct Animal { ~virtual Animal() {} }; struct Dog : Animal {}; struct Cat : Animal {}; struct Bird : Animal {}; int main() { Dog d; Animal&amp; animal=d; std::cout &lt;&lt; typeid(animal).name() &lt;&lt; std::endl; //Dog return 0; } </code></pre> <p>As others have written it's better not to rely on <code>name()</code>. But without some code it's not easy to say what's correct.</p>

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
