I have a few PDA benchmarks at:

They are for the SQLite ADO.NET 2.0 wrapper of course, but they can give you
a rough idea.

Hi,
Does anyone have experience use SQLite on a Palm or Pocket-PC handheld?
I want the speed of an indexed database. I need faster data access than I get
from the Palm files on my Palm Tungsten T3. I can give more details, but the
main point is, as I sai, I nee help using SQLite on hanhels.

How do I subtract two dates and get the answer in minutes?

If you're not part of the solution, you're part of the precipitate.
So I first had these commands:
create table blah (b INTEGER, c INTEGER);
insert into blah values(400,300);
insert into blah values(360,250);
select a,max(b-a) from blah where c=a and a > 200 and a < 500;
That didn't work: 'a' doesn't exist. So I looked in the help and changed the
last line to
I tried without using a bound column name, that took care of it. Thanks

Anish,
So my problem of retrieving 1,000,000 random records 1,000,000 times
works fine for 15 bytes. But it is taking too long a time for 1k
records. It is almost taking 102 seconds for retrieving 50,000 records
of size 1k. Can u suggest me a way for reducing the time taken for the
same? I
Actually, I thought it would fix my problem but it seems like it persists.
What seems to happen is that the generate parse.h file stops at token ID
#136. I can hack my way through although it does not make sense to me why
TK_SPACE would not be generated from the parse.y file.
In case it makes

Alas, it's nowhere near so simple. There will be other processes that
*can* be writing the file at the same time, so we still need an
advisory locking mechanism.
In case you were wondering, we're trying to implement row-level
access control (using views and triggering write operations

Since locking will require me to invoke (slow) IPC mechanisms, I
don't want to send any more lock messages off to my lock server than
absolutely necessary; any suggestions on how I should approach that?
Try to look at the os_win.c file

I'm working on a system in which I'm using SQLite to open a number of
database files and to perform operations on aggregate views of those

The problem I've got is, some of the files I want SQLite to open and
SELECT from, I can only acquire read access to. And the

Hi Dennis,
I corrected one problem of mine, but is left with another. As
you told me, I tried creating index for the seq_number. But I came to
know that if we are creating a table and assigning primary key to a
particular column (here seq_number), we do not want to create index for
that

Is the database really corrupt, or are you getting

truely corrupt or not by running

I will check this.

Hi,
I think the simplest solution would be to put a spatial index on top of the
B-tree, that's what e.g. Oracle does in their Spatial Cartridge.
Basically you store the index data in relations and index these relations by
B-trees.
In this case, you do not have to change
