    1. COSorry, but the fact that you say "i need the sum logic in a separate temporary variable like below", doesn't mean at all that doing this is needed. You need either to provide a realistic example that convinces the reader that this is necessary, or otherwise just use the solutions that have been proposed. Two solutions have been given, that produce exactly the wanted output, without capturing the sum in an intermediary variable. This proves that such capturing is unnecessary -- unless you convince us to the opposite.

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).
