Re: Problems with "order by clause"

Hi Barry,

I forgot to point out that the oracle and sapdb results I got via JDBC
differed from
the results I got directly in SQL-Plus resp. SQL-Studio:

Tralala
tralala
tralal

This led me to the assumption, that JDBC is doing some kind of
formatting or something (?).
To speak clearly:
The results I get in a db console under oracle, sapdb and PostgreSQL are all
the same, while the JDBC results differ in the way described below. This
is what seems
really weird to me...

Looking forward to any further suggestions,

Erik
