Method queryRowScan

server/attach_timeout.go:115–119

queryRowScan runs a single-row query with the default attachStepTimeout and scans the result into dest. On timeout dest is NOT written; callers must treat a non-nil error as "value unknown" (all current callers do).

(query string, dest ...any)

// scans the result into dest. On timeout dest is NOT written; callers must
// treat a non-nil error as "value unknown" (all current callers do).
func (a *attachStepExecer) queryRowScan(query string, dest ...any) error {
	return a.run(attachStepTimeout, query, func(ctx context.Context) error {
		return a.db.QueryRowContext(ctx, query).Scan(dest...)
	})
}

// run executes fn (one DuckDB statement) under a timeout. See the
// attachStepExecer doc comment for the two-layer deadline semantics.
