Ah! I found my fault in the test code.
The delete performance was measured incorrectly, so I re-examed the
performance. It still shows outstanding performance compared to insert
performance, but it is a reasonable gap.

One things to bear in mind is will you need to query data across all users?
Perhaps a report or some stats for all users?
If so, this is much more problematic if you have one DB per user, since you
would need to ATTACH all the separate files to enable the query to work. A
single DB file, such
select avg((select 100 union select 200))
Returns 100
I would have expected 150? Am I being thick or is it a bug?

Adding to the free list will touch each page at most once, and thus
caching adds no benefit (and has no loss for a smaller cache.)
Inserting may touch each page multiple times, for such operations as
rebalancing the tree.

Surely not FILE_SHARE_WRITE! You don't want other processes writing
the database while you're copying it.
1) I make 1 DB having data for so many users.
2) I make seperate DB for each user
Second approach implies that you'd have to do your own database files
(users) management when adding/removing users. It also means you

Mikey,
Try this instead:

You are passing a table to avg (and it ignored all but the first
Actually, I have just realized that I indeed cannot use BEGIN IMMEDIATE to
do the locking because it has to be locked from the process that has no
SQLite in it...
And you already delievered the exact answer of how to do it!
Thanks a lot!

Andrew,
If you are asking about case insensitive name comparisons, then there is
a way. You must declare the name column in your table to use the NOCASE
collation.

greatly if i could also get the offset out of the query. So i can then
calculate the next offset and limit. For example:

You can test this requirement using the sqlite3 command line utility.
