IMHO 180 mln rows is no small deal even for a big database - especially
considering you have got text column in it.

Is it possible (if so how) to programmatically determine version of
sqlite that is in use?
Ie something like this: select @@version
The reason I ask is because I have some .NET code that uses Mono as
run-time, and it seems that in some cases Mono picks some other sqlite
DLL than the one
of inserted rows, so instead of: DELETE + INSERTS, you will
have INSERTS + UPDATE. You will need to truncate table once in a while
or even drop/create it.

No, sqlite3 uses database-level locking, either one process can

Any plans for internal queueing of queries waiting for their turn to
write rather than just return database locked?

Any wrapped or API that loads row values into a hash, and if some

exactly the same names then they would overwrite information in the
hash.

This is your problem.
Each thread should use an isolated connection.

Hi all,
Today I had database corruption (running v3.0.7 on Windows using ADO

anti-locking wrapper on top). All of a sudden queries stopped working
with error returned

death since

Hi all,
This is my first post here, so I'd like to express thanks to Mr D.
Richard Hipp for creating
such a great small database!
Now here is my question -- it appears that it is not possible to update
table
while doing join with other tables, something I got so used to with
"big" databases.
