Възможно е да няма прост отговор на основния въпрос. Предполагам, че се опитвате да пишете правилно адресите с главни букви на холандски и този въпрос е свързан с този друг въпрос от вчера.
Комбинирайки въпросите, досега има поне три специални случая:
'S GRAVENHAGE => 's Gravenhage
IJSLAND => IJsland
SON EN BREUGEL => Son en Breugel
INITCAP и дори NLS_INITCAP('...', 'NLS_SORT=xDutch') не успяват да се справят правилно с тях. Преди да започнете да кодирате, трябва да съберете всички изисквания. Това ли са единствените правила за изписване на холандски с главни букви или има много повече?
Отговорите, публикувани досега, могат да помогнат за разрешаването на едно конкретно изключение. Но има вероятност да не можете просто да комбинирате регулярни изрази и да ги разрешите всички. Тук може да искате да възприемете по-скоро подход отгоре надолу.
АКТУАЛИЗАЦИЯ
Въз основа на идеята на wolφi е възможно проблемът да се форсира грубо, като се използват всички съществуващи имена. NLS_INITCAP сам работи 95% от времето. Използване на 431 имена от електронната таблица на тази връзка възможно е да се състави списък от всичките 25 изключителни случая.
Изпълнете този оператор веднъж, за да създадете DECODE израз за обработка на всички нетривиални случаи:
