How to Support Java 6, 8, 9 in a Single API
With jOOQ 3.7, we have finally added formal support for Java 8 features. This opened the door to a lot of nice improvements, such as: Creating result streams try (Stream<Record2<String, String>> stream = DSL.using(configuration) .select(FIRST_NAME, LAST_NAME) .from(PERSON) .stream()) { List<String> people = stream.map(p -> p.value1() + " " + p.value2()) .collect(Collectors.toList()); } Calling statements asynchronously … Continue reading How to Support Java 6, 8, 9 in a Single API
