Multi-threading has nothing to do with multi-processing (multiple
instances). SQLite always works from multiple processes (if OS
permits; note: Windows is a

Hi all.
I have some customer that are executing more instances of my windows app
that use Sqlite as database,
so more instances of my app works on the Sqlite database on the same time.
My question:
I am using the last standard Sqlite3 lib generated from the amalgamation,
Do I need to activa

If I BEGIN a transaction and perform a number of INSERTS, UPDATES, and
DELETES, then do a SELECT, will the data selected be the original
unmodified data?
In other words, do I need to COMMIT before I see the changes reflected in
a SELECT?
I can see use cases where I'd desire both behaviors. 1)

Hi Jean-Christophe no no, I had two problems with the wrong syntax and the
problem with the sqlite wrapper. The syntax matches now, for the crash of
the command I will set QNX a ticket. Learned a lot -:), thank you all, and
all the best for the new year.

Hey,
i found the solution for the utf-8 encoding problem:
i used the:
wchar_t chAppWinTextUnicode[MAX_PATH] = { 0 };
::*GetWindowTextW*(hWnd, chAppWinTextUnicode, MAX_PATH);
int nSize = *WideCharToMultiByte*(/*CP_UTF8*/, 0, chAppWinTextUnicode,
-1, NULL, 0, NULL, NULL);
char* pchBuffer= (char*)

In the desperate hopes that the first email either didn’t send or just got
lost in the flurry, I am asking my question a second time.

Hi,
I want to sort Special Characters,Digits, Latin and Greek
Characters(language independent sorting order) using ICU collation.
The sorting order shall be approached by separating the character set into
three groups:
a. special characters (i.e. +, -, &, Space, etc.)
b. digits (0-9)
c. Latin
