    <p>Using MySQL, i'm selecting a list of songs in spanish that i would like to sort. Here's a list of names that is returned by the query:</p> <ul> <li>¡Decirevilla!</li> <li>Alhambra</li> <li>123 pasitos</li> <li>África</li> <li>Arroz</li> <li>Decir</li> </ul> <p>The sorted list should look like this:</p> <ul> <li>123 pasitos</li> <li>África</li> <li>Alhambra</li> <li>Arroz</li> <li>¡Decirevilla!</li> <li>Decir</li> </ul> <p>After all of the research i've read, i've concluded that there is no reasonable way to achieve this using MySQL. I've tried collation, charset, etc... but there is no way the character ¡, ?, etc... can by sorted accordingly to my desired result. Even the Á is not sorted the way i want to...</p> <p>Question 1: Is this a reasonable conclusion?</p> <p>I believe the only way to achieve this is by passing the results to an array in php and then sort the array using a custom function... all this using the function usort (need to sort by value and i don't care about maintaning the key association). Something similar to this:</p> <pre><code>function normalize($a, $b) { if ($a == $b) { return 0; } return ($a &lt; $b) ? -1 : 1; } $tracks = array(); while ($row = $result-&gt;fetch_assoc()) { $tracks[] = $row; } usort($tracks, 'normalize'); </code></pre> <p>Question 2: Is this the best way to achieve a custom sorting?</p> <p>Here's where i'm hitting a wall:</p> <p>Question 3: I have no idea how to create the normalize function to sort the names accordingly to my needs. How do i ignore certain characters (¡, ?, ', !, ¿) and how do i replace other characters with the natural equivalent (Á -> A, É -> E, etc..) I believe that by ignoring certain characters and replacing others, i can achieve the sorting i'm loojing for...</p> <p>Question 4: All this make sense? Am i on the right path?</p> <p>Thanks in advance for all your advice. Marco</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.
