Как вы можете увидеть здесь. В моем первом [b] resultset [/b] myfirstrs Обновление! Потому что без этого база данных вернет то, что она хочет, так что я сделал, это изменить запрос и добавить пункт «Порядок по заказу», подобное этому: < /p>
String searchSECTIONSETTINGS = "SELECT allsections_list.`SECTION_ID`, allsections_settings.ADVISER_ASSIGNED, allsections_settings.SECTION_POPULIMIT,\n" +
"allsections_settings.ROOM_ASSGN, allsections_settings.YRLEVEL_ASSGN, allsections_settings.SCHOOL_YEAR, allsections_settings.SESSION_ASSIGNED\n" +
"FROM allsections_list\n" +
"RIGHT JOIN allsections_settings\n" +
"ON allsections_list.`SECTION_ID` = allsections_settings.`SECTION_ID`" +
"ORDER BY allsections_list.SECTION_ID";
< /code>
Все еще дает мне неправильные значения, когда я запускаю проект. Я попытался запустить это в запросе NetBeans и дать мне значения в порядке ASC.>
