    <p>After running node for a long time I get this error. My program itself works perfectly fine. What does it really mean? I can't find anything about it. And most importantly how to prevent it?</p> <pre><code>Error: read ETIMEDOUT at errnoException (net.js:901:11) at TCP.onread (net.js:556:19) -------------------- at Query.Sequence (/nodejs/node_modules/mysql/lib/protocol/sequences/Sequence.js:15:20) at new Query (/nodejs/node_modules/mysql/lib/protocol/sequences/Query.js:12:12) at Function.Connection.createQuery (/nodejs/node_modules/mysql/lib/Connection.js:48:10) at Connection.query (/nodejs/node_modules/mysql/lib/Connection.js:100:26) at Socket.&lt;anonymous&gt; (/nodejs/server.js:23:12) at Socket.EventEmitter.emit [as $emit] (events.js:95:17) at SocketNamespace.handlePacket (/nodejs/node_modules/socket.io/lib/namespace.js:335:22) at Manager.onClientMessage (/nodejs/node_modules/socket.io/lib/manager.js:488:38) at WebSocket.Transport.onMessage (/nodejs/node_modules/socket.io/lib/transport.js:387:20) at Parser.&lt;anonymous&gt; (/nodejs/node_modules/socket.io/lib/transports/websocket/hybi-16.js:39:10) </code></pre> <p>I guess it has to do something with the <code>mysql</code> I'm using in my program because it refers to <code>Query.sequence</code> or something. <a href="https://github.com/felixge/node-mysql" rel="nofollow">https://github.com/felixge/node-mysql</a></p> <p>The only line I can refer to that causes this error is where I create a query:</p> <pre><code>database.query("SELECT * FROM `... </code></pre>

    1. COTCP packets got lost on the way from the MySQL server or perhaps the server crashed or was too busy. node-mysql is waiting for a response from the server (TCP.onread) but it took too long so it got bored and stopped waiting and told you that it timed out (ETIMEDOUT). The solution is to reconnect when that happens and reissue the query.

    3. COThe first parameter to the callback is `err`. If it exists, then there was an error. if `err.code === 'ETIMEDOUT'` then there was a timeout.

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).
