Hi Jose,
thanks for your explanations. :)
AFAIR it is a good practice to separate OLTP and OLAP databases. In this
case you do not impact interactivity and feel free to
rotate/transform/reformat data as you wish.

It is unlikely that szQuery string is 512 characters long. So you
instruct SQLite to compile a long string of garbage. sqlite3_prepare

It's not an error. It's a success code meaning that you've reached the
end of resultset. If you get that on the very first call to
sqlite3_step, it means your resultset is empty - there are no rows
Yes, I can open the file created on the server on my laptop. No, I haven't
changed anything on the server that would have caused this. Even when I run

I far as i know you compile with php5-pdo-sqlite, but this was only tested
