Greetings,
I have an application that uses SQLite 3.3.2 right now, and I'm
looking to move to 3.5.2. The problem I have right now is that 3.5.2
can't open the 3.3.2 formatted database files. I know that the file
format changed, and then changed back, but I thought there was still a
way to get

Hello there,
I have a couple related questions:
1) Is anyone aware of any recent cases of SQLite DB corruption? We
upgraded from SQLite 3.3.6 to SQLite 3.4.1 a few months ago. In the
last couple days, we've encountered a couple cases of SQLite reporting
that a DB file had become corrupted
Most languages have the ability to kick off different threads that run in
the background. You can have a writer thread that dumps the queue and then
sleeps for another minute and then continues the loop. I don't know PHP,
but a quick search found that it does have a Thread class which I

I am using sqlite3 in a DAQ device. Data can be viewed on the unit using a
Rails enabled web server.
The data is being stored to the database every 1 to 5 seconds. I wanted to
leave the the database open for as long as teh application is running and
then use a IMMEDIATE, PREPARE-INSERT(x),
Hi All,
I could use your help in finding an optimal query for the following:

INSERT INTO "chain" VALUES(2,3);
INSERT INTO "chain" VALUES(3,4);

Dear Fred,
I am using SQLite always in conjunction with PHP for web applications.
To give you an idea about the possibilities :

- holds history for approx. 10.000 files with regards to accounting and
timesheets referenced to those files
- holds complete

I use static libraries and gcc. Just use --enable-static and you should
get the link library created.

You could maintain a queue in memory of all the data to be written, have
each page view queue up the new data and have a single db writer thread that
dequeues items and writes to the db. That way you get the benefit of
writing directly to the db, but do not have the extra overhead on each page
Size should not be a problem.
Thank you very much!

Hi,
the colors of the links are reversed: By default,
links that have not been visited are blue and visited
links are purple. The sqlite website makes visited links
green and unvisited links purple.
This is *very* confusing.

Hi all:
Instead the supplied DLL, I would like to statically link the SQLite
library in a new project, and I wonder if someone has build a SQLite static
library xxx.a using minGW in Windows and the sources/headers contanied in
the sqlite-source-3_5_2.zip
Any tips on that are welcome.
