Hi SQLite users
Thank you for your attention - I am just hoping for some clarification
of usability of SQLite.
Referring to: http://www.sqlite.org/whentouse.html
- SQLite works well in websites
- Other RDBMS may work better for Client/Server applications
- SQLite will work over a network file
Good thought, but
1. I set the connection
2. get the array
3. dump it in the sheet
4. and then close the connection.
The crash happens at number 2.
I am sure I must be overlooking something simple here. The trouble is that
this error is not consistent.

I am not an expert on SQLite - but if you are running separate
websites from your multiple servers, then why not use 4 instances of
SQLite ?? That is unless the websites need to share the same
database/tables.
If they do need to share the same database/tables, then PostgreSQL or
MySQL
Thanks for replying Phil...
Actually I am not running separate websites - but I have to deploy to
multiple webservers which will all serve the same pages. Each webserver
will have their own copy of the SQLite code, but they need to load the
data from a network file server to share the same data.
And this is when I'll step back and listen to the experts...
Since it is a low-load situation, file/record locking on SQLite seems
like it would be acceptable to me.
As for data corruption - that's bad -- very bad. However, with
automated backups some degree of comfort may be realized.
I'd be _extremely_ leery of doing this on a network store. In theory,
it should work just fine, but bridging theory and practice may very
well cost you many sleepless nights. sqlite is in many ways easier
than mysql, but mysql isn't _that_ much harder to use, and it just
won't have this class
That's what I'm talking about! It's good to get the perspective from
your setup, Phil. I'm beginning to get the picture.

corruption seems almost impossible when

By separate files, do you mean that each user has their own data store?
If so, why not do the same thing with SQLite? If each user has a unique

That's the principle I am currently using, but that functionality is

Ok - it looks like the network file system is the main problem. That is
what introduces the risk of database corruption, and 'quickly' too!
SQLite apparently locks perfectly well and maintains integrity through
concurrent access but the network file system is likely to break.
