Hi Thomas,
I read about this new hdb interface, but in fact the code is much bigger than this example, so, I still need to plan this refactoring.
The funny thing is that, even in the web catalog "/sap/hana/ide/catalog/" this error regarding the charset occurs (now on SP9 - SP8 was also fine).
Anyway, thanks for the fast answer.
Schönes Wochenende.
