    <p>Allows basic access to a MySQL database.</p>
    <p>This node uses the <b>query</b> operation against the configured database. This does allow both INSERTS and DELETES.
    By it's very nature it allows SQL injection... so <i>be careful out there...</i></p>
    <p><b>msg.topic</b> must hold the <i>query</i> for the database, and the result is returned in <b>msg.payload</b>.</p>
    <p>Typically the returned payload will be an array of the result rows.</p>
    <p>If nothing is found for the key then <i>null</i> is returned,</p>
    <p>The reconnect timeout in milliseconds can be changed by adding a line to <b>settings.js</b>
    <pre>mysqlReconnectTime: 30000,</pre></p>
