So you're wanting to FTP into the AS400 directly? That makes sense.
All you need to do is download the amalgamation to compile the shell. Just
sqlite3.c and shell.c
Hopefully you already know how to use the C compiler on your AS400.
Then transfer one of your sqlite databases over and ru
We just want to simplify the process. If pc goes down our files wont be
converted and its just another piece to troubleshoot. As400 can compile C so
that is an option. I don't think anyone has done something like this and
there is not much info on it.

Do you have a C compiler on the AS400 you can use?
I couldn't find anybody doing this so if you want to avoid the PC side you may
be on your own to build the shell.
I assume there's some logical reason for not doing the sql dump on the PC side?

Yesjust use the sqlite shell to .dump the database on whatever other
platform you have and copy the file over.
You need to do this in the shell.
.output sqlout.txt
.dump
.quit
If there's nothing crazy in the database it may well be 100% compatible with
db2.

It seems to me that this has the same effect as a memory mapped file would.

No we do not need an ongoing connection. The dump method would be fine but
does it have to first be run on the pc side. Anyone try compile sqlite3 to

For one of the message types (video frames), the blob size is ~100K; for

Any reason you can't just .dump your SQLite database and import into db2?
Or do you need an ongoing connection?
There's a guy in this thread that connected his Linux system to AS400 using PHP
but the .dump/import would be a lot easier.

The example of a CREATE TRIGGER statement from the help page is:

The use of BEGIN and END to wrap the statement leads me to believe that

Hi,
I'm using freelist_count pragma to test whether my sqlite db needs vacuuming.
I'm running intensive inserts and deletes to the DB very often.
I run the freelist_count pragma periodically and I get different values every
time - sometimes I get large number and sometimes I get 0 or 1.

expect that
the number of changes is null.

For the quick and dirty solution, I think you can use something like this to

not too sure about speed.
