    1. COAre your service and your client running on the same machine? This is definitly a network related error, so i guess your service is not running or does not bind the port 8010. Open a command prompt and try to connect with "telnet localhost 8010" on the machine where your service is running. If you don't get a connection, your service is definitly not listening on port 8010.

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).
