Ok, thankyou for your replies
@Igor: I think you misunderstood. I only have one connection to the
database (provided by the JDBC driver). I only care about and use that
one connection (no other applications access the database). I was
wondering if database trigger could be used to notify the appli
Thanks, I've tried that, but to no avail.
Maybe a bit of background, our applaiction generates its froms from the
database layout, this is so it can be used for a variety tasks. It talks
to mysql and sqlite, so I was trying to keep the code as generic as
possibe.
I have a procedure - prepareStatem

I imagine you could make the trigger call a user function which notifies
the application...

Hi,
I am developing a p2p application (in Java) which has a SQLite
database attached. I am currently using the sqlitejdbc JDBC driver for
database access.
Ideally, I want SQLite to notify the application whenever a change is
made in the database, so it can propagate the change to other peers.

Use PreparedStatement setBytes method.
No need to convert to base64.

Hi, I've been tearining my hair out trying to figure out how store my
image data in sqlite using Java. I think the best way to go is just store
the base64 encoded string in the column, but I can for the life of me get
a prepared statement for that to work.
Can anybody show me how they are storing

According to SQLite sources:

Hi Tom,
Whilst not knowing much about the process, I have a recollection about
something in the documentation that said if sqlite thought that there
was a potential for deadlock the busy handler was never even called.
Could that explain this ?
Cheers
