This option is similar to \gset, except that it is able to store all results from combined SQL queries into separate variables. If a query returns multiple rows, the last result is stored and if a query returns no rows, nothing is stored. While on it, add a TAP test for \gset to check for a failure when a query returns multiple rows.
