Hi Chris,
First of all, thank you for keep trying to help me, it's much appreciated 
I've started one of the problem database manually and I got this with dbinfo:
C:\Users\PeterDV.VARTEC-ADM\Desktop>"C:\Program Files (x86)\Sybase\SQL Anywhere
9\win32\dbinfo.exe" -c "userid=DBA;password=stef;eng=BANDENM&W"
Adaptive Server Anywhere Information Utility Version 9.0.2.3198
Database : W:\TOP\DATA\BANDENM&W\BANDENM&W.DB
Log file : none
Log mirror: none
Compressed: No
Page size : 8192
Encrypted : No
Strings padded with blanks for comparisons: No
Respect letter-case when comparing: No ('A' equal to 'a')
Collation sequence: 1252LATIN1 (Code Page 1252, Windows Latin 1, Western)
Java classes installed: No
Database checksums enabled: No
I don't know if this is the right way to check it? Since in my java code the database is started from within another database ...
As for the other query, I now get a result: an empty resultset
