Salam, Thank you very much for your help, i think the problem was due to JDBC-4. i've reiterate the manipulation as you described with the JDBC-3, and now it's ok, so afterthat i switched back once again to JDBC4 and it's still ok.
I'll try to investigate the problem with another machine to see more clearly. Thank you again for your help and your time, Good luck ! -- Amine Arrahmane Achargui Effectiveness (“Do the right things”) Efficiency (“Do the things right”) Great to see that great projects choose to use great projects to become even greater -- Unsubscribe instructions: E-mail to users+h...@libreoffice.org Posting guidelines + more: http://wiki.documentfoundation.org/Netiquette List archive: http://listarchives.libreoffice.org/www/users/ All messages sent to this list will be publicly archived and cannot be deleted
