multiple LEFT JOINs do not work as expected

Hi, We have a hierarchical data set of organisations in the database, where each organisation stores a reference to it parent organisation. I'm trying to find all organisations 2 levels under a root organisation, e.g. where organisation.parentOrg is the root or organisation.parentOrg.parentOrg is the root. The query also contains a number of other predicates and it is built dynamically using Criteria API. It could be looking for other number of levels, 2 is just an example. The test query looks like this: ... The root organisation has null as it's parent. The log generated when I run this against the DB is attached. Could you ...

Is there an update on running ObjectDB purely in-memory?

Hi, I know that this has been asked, but the last time seems to be two years ago, so I'd like to know whether there is a change or an outlook regarding the topic: Is it possible, or planned, to run ObjectDB purely in-memory, without a any file on disk? Note that "file on RAM disk", which was proposed in the past, is not an option for the application I have in mind. It would need to be true in-memory mode, as supported by SQL databases like H2 or SQLite. Thanks, David #1 2015-10-09 09:23 Hi, I know that this has been asked, but the last time seems to be two years ago, so I'd like to know ...

How to configure where the ODB is stored?

Hi, The documentation is lacking in this respect. How do I configure where the ObjectDB database file is stored. I need to know where it is so I can inspect it with 'database explorer'. The docs say to set it to "$objectdb/db/points.odb" and that this defaults to "the installation directory of ObjectDB". BUT... I DIDN'T INSTALL OBJECTDB - my maven build downloaded it and embeded it. So, where is this file stored??? Also, the contents of the DB don't seem to be persisted between AppServer restarts.  ... but i find  log folder in the path defined for objectdb.home but  the ...
