Hello,
we are currently running the H2-database successfully on Android using
multiple apps to acces it via the mixed-mode.
Occasionally we get an error when opening the database: The file seems to
be locked.
Restarting the device (and thus all apps accessing the database) leads to
the exceptio
I don't really understand all the details, but could it be a problem if
other processes access the database at the same time?
If so, is there a way to tell H2 to not allow new connections (and close
all connections except the current one)?

Hello,
we are currently using H2 on Android for accessing from multiple processes.
In order to allow backups and recovery of the database in case of

Hi!
I'm seeing the same issue on 1.4.187. It happens intermittently and I'm not
able to find a way to easily reproduce it. This is definitely a blocker for
us so I'm going to revert back to an older version for now.

Hi,
for a project I need to know the syntactical differences between H2SQL and
PostgreSQL. Has somebody already done this?
Note: I am not planing to simply convert databases from this to that, so
something like Flywaydb is not what I am looking for...
Thanks,

to iterate all rows, calculate the value and then update a single row and

I couldn't find an example or way to do this via a stored procedure. But
maybe an update via a fetch logic is also possible.
What is the fastest to implement such a complex update?

Hi list,

Well, thats not possible, because the file is created with user
permissions only. So no one else can delete it.
The lock-file is also completely disable-able.

If the database is used by (system)user A, the log-files owner is user
A. Now, if (system)user B tries to open the db, h2 tries to delete the
old log file which is not possible because A is the owner, and not B.

What sort of tools do people use for visual data modeling with H2?
It would be great to have a tool which allowed the developer to draw E/
R diagrams, and visually build queries - and then output DDL for H2.
I'm currently evaluating Toad Data Modeler - which doesn't
specifically support H2, and
