From my comment at https://bugs.documentfoundation.org/show_bug.cgi?id=44854#c0 Upgrading the bundled HSQLDB to the latest 2.x would bring new features and better ANSI SQL support for embedded-in-odb-file databases. See e.g. bug 39872, and also support for "IS [NOT] DISTINCT FROM" comparisons. > i thought we use an old version of HSQLDB because its file format > changed and so if we upgrade then we create compatibility issues with > HSQLDB files embedded in ODB documents; is there more backward > compatibility nowadays? No, upgrade to HSQLDB will need a proper "file format changed" migration path. AFAIK, there was some feature branch of OpenOffice.org that had the beginnings of that, with a pop-up of "would you like to upgrade the database format now and lose backward compatibility with older versions of OpenOffice?". From my comment at https://bugs.documentfoundation.org/show_bug.cgi?id=44854#c0 The HSQL developers pledge to collaborate with us on that. See http://hsqldb.org/web/openoffice.html There is also a OO.org CWS with work on that, namely hsqldb19? -- Lionel _______________________________________________ LibreOffice mailing list LibreOffice@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/libreoffice
