Always defer *sql.Rows.Close and consult with Err (#844)
* Always defer *sql.Rows.Close and consult with Err database/sql.Rows.Next() makes sure to call Close only after exhausting result rows which would NOT happen when returning early from a bad Scan. Close being idempotent makes it a great candidate to get always deferred regardless of what happens later on the result set. This change also makes sure call Err() after exhausting Next() and propagate non-nil results from it as the documentation advises. Closes #764 Signed-off-by: Kiril Vladimiroff <kiril@vladimiroff.org> * Override named result parameters in last returns Signed-off-by: Kiril Vladimiroff <kiril@vladimiroff.org> * Do the same over new changes that got merged Signed-off-by: Kiril Vladimiroff <kiril@vladimiroff.org> Co-authored-by: Neil Alexander <neilalexander@users.noreply.github.com>
