Hi All,
by reading that the statements works for all of you, I thought that my problem has to do with the way I am entering the statement. Instead of copy & paste from an example within a Wiki page, I entered it manually into the SQL console and now it works also for me ;-)
Hence, the SQL console is not purely in ASCI mode that would eleminate any special formating options of other sources. My problem was that the single quote of my insert statement looks the same, as the it would appear from a keyboard. But it was not the case. Somehow the single quotes contained formating stuff. Anyway entering the entire insert manually worked in my case.
Thanks again for all your help. It helped really to know that it works for you and that HANA does not need any special escape sequence to insert special characters.
Best Regards.
Markus
