Dear All,
Thank you to the member for fast reply
Are there anyone can give simple sample code in Visual C++,

Not for collations, just user defined functions. It is a bit of a pain to
deal with. I have the same issue in APSW but at least I can still report a

Unfornately I can't do that: it would mean I place a maximum size on a
work space allocated at creation for manipulating user strings, which
is taboo in my view.
This is for getting unaccented copies of inpu

Hi all,
I use an SQLite database w/ the rtree extension to hold information
about genetic polymorphism (snp's), based on UCSC's mapping work and
their mysql table dumps. My database is write-once, read from then
on.
One of the tables has almost 19 million rows. This is the table on
which I bui

The SEE extensions add a couple new API calls, specifically sqlite_key() and
rekey() functions to specify the password (or change the password) for an

Hi, I was using sqlite as a database for my program. My program is

My questions :
1. Are there problems if I add SEE ?
2. Do I have change a lot in my program ?
3. How
