[sqlite] Database locked error with only one process?

I read around, and it seems that the consensus is it should only be locked during a multi-thread/multi-process update. However I encountered the error in a python script (single proc/single thread) that was the only reader/writer to the database. It seems that I forgot to con.commit() in a loop

I'm trying to figure out how SQLite3 would read the schema and data off the disk below. I read https://www.sqlite.org/fileformat2.html but didn't find what I was looking for. In college databases, we calculated the estimated number of blocks (512-byte device blocks) read given schema and

[sqlite] Error: no such column: When column exists!

So after further review, there is a 0xa0 (non-breaking space - ) character - a non-breaking space before the semi-colon. Thus making the column name analogous to ptn.TreatmentNoteID_; I guess it is functioning as intended? > Sent: Wednesday, July 15, 2015 at 3:53 PM > From: &q

Ok, I've dropped irrelevant tables, dropped the data, vacuumed, and am attaching the result. (Does this ML support attachments?) I was using v3.7.17, I tried the 3.8.5 and 3.8.10 releases, and all are the same error. > Sent: Wednesday, July 15, 2015 at 10:28 AM > From: "Donald Griggs" > To:

[sqlite] SQLite clusters?

I'm transitioning my job from embedded space to Hadoop space. I was wondering if it is possible to come up with a SQLite cluster adaptation. I will give you a crash course in hadoop. Basically we get a very large CSV, which is chopped up into 64MB chunks, and distributed to a number of nodes.
