So basically, it seems, ROLLBACK, COMMIT or END would all do nicely in this
particular context. Hopefully I'll never need to worry about locking etc

Interesting. That sounds like exactly what I need. I'm curious, did
the patch somehow arise from my query, or is the timing of the query
and the patch just coincidental?
Also, how soon would you expect this patch to make it into an
"official build"? I've never built SQLite from the sources

1. Review your oracle 10g db and fix the "HUGE I/O" issues.
2. Why not do the lookups using oracle? Allocate the extra 5 gig to the oracle
buffer cache.
3. If you want good lookup performance, try to use the Array level interface
so that you don't need to take multiple trips (context switch)
Can you consolidate your multiple binaries to a Single Binary?
Then Use threading and sqlite's shared caching to perform the Lookups and
updates.
That way the cache wouldn't get invalidated???
Someone else here correct me if this is a bad idea!!!

We have implemented a decimal arithmetic module to handle money in
Sqlite. It uses the regular SQL definitions and maintains precison and
scale. The data are stored as TEXT and in "display format", right
aligned with leading spaces so that they display without editing or
radix transformation

Until now, our users were mostly single-hosts, and the few who did share
an SQLite database through a shared drive had a small database and very low
concurrency. But a couple of new ones have a DB that's about 50MB, running
on a 10Mbps LAN... and an INSERT takes about 10 seconds :-/
