Just out of curiosity: Maybe someone can report the result of 'SELECT 5 / 2;'
on MySql, SQLServer, and others?

Hello Dennis & Jay,
thanks for your detailed answers. I do understand your arguments and they make
good sense for typed DB engines, but for the case of SQLite3 I dare to differ.

What didn't you like about SQLiteManager? I have found the developer
very responsive to bug fixes, requests and patches, so I would recommend
detailing things that you didn't like or didn't work correctly for you
and sending it to him.
At the time that I was actively looking, I found it to be

Hi,
does anybody know whether a code example for
User-defined Collating Sequences in C exists, and
where I can find such an example.
Or even better has somebody already implemented such a

In the C language, which sqlite is written in, performs math this way:
If mixing types the operands are converted to the most precise type and the
operation
evaluated.
=> SELECT 5 / 2;
is: integer operation integer
the most precise type is integer, so it's strictly integer math.

Hello,
I have a database file placed onto a NTFS LAN based local server.
Application's on different machines tries to access this database file and
update it frequently.
I am using Christian Werner's ODBC Driver. I am facing "Database is locked"

Hi,
I'd like to know how could I customize the features of sqlite and compile it
in a dll like the one I use in my .net app that is the one that I've download
pre-compiled from the sqlite website.
