    <p>This is a quick mockup of the code you could use (it probably isn't working and has bugs in it, but it shows the way it could be done):</p> <pre><code>var CircularQueueItem = function(value, next, back) { this.next = next; this.value = value; this.back = back; return this; }; var CircularQueue = function(queueLength){ /// &lt;summary&gt;Creates a circular queue of specified length&lt;/summary&gt; /// &lt;param name="queueLength" type="int"&gt;Length of the circular queue&lt;/type&gt; this._current = new CircularQueueItem(undefined, undefined, undefined); var item = this._current; for(var i = 0; i &lt; queueLength - 1; i++) { item.next = new CircularQueueItem(undefined, undefined, item); item = item.next; } item.next = this._current; this._current.back = item; } CircularQueue.prototype.push = function(value){ /// &lt;summary&gt;Pushes a value/object into the circular queue&lt;/summary&gt; /// &lt;param name="value"&gt;Any value/object that should be stored into the queue&lt;/param&gt; this._current.value = value; this._current = this._current.next; }; CircularQueue.prototype.pop = function(){ /// &lt;summary&gt;Gets the last pushed value/object from the circular queue&lt;/summary&gt; /// &lt;returns&gt;Returns the last pushed value/object from the circular queue&lt;/returns&gt; this._current = this._current.back; return this._current.value; }; </code></pre> <p>using this object would be like:</p> <pre><code>var queue = new CircularQueue(10); // a circular queue with 10 items queue.push(10); queue.push(20); alert(queue.pop()); alert(queue.pop()); </code></pre> <p>You could of course implement it using array as well with a class that would internally use an array and keep a value of the current item index and moving that one.</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).
