Hello,
The merge statement is really missing in sqlite...
Is there any plan to integrate this SQL 2003 syntax in sqlite?
Best regards,

Hi, ALL,
Consider this:
std::string query = ;
if( ( result = sqlite3_prepare_v2( handle, query, -1 stmt, 0 ) ) != SQLITE_OK )
{
// Should there be call to sqlite3_finalize. I.e. can I safely assume
that since it failed all memory is not being allocated
}
Thank you.

SQLite does have this form of the INSERT statement:
INSERT (OR REPLACE/IGNORE) INTO table1 SELECT * FROM table2
Do you have specific requirements for the UPDATE

neither on MSVC neither on MinGW.

Hello SQLite users,
I was wondering, if closing the database connection after each transaction is a
good idea.
Possibly I've missed the thread concerning this topic. If this is true, please

Otherwise, can anybody give a reliable advice to do it in this or that way. I
If the database files are being handled as a document, what I would suggest
then is to use SQLites Backup API, and work off of the backup API.

This means that the user is going to be free to do whatever they want with
the file in their documents directory. When

One possibility has to be that your one problem user is on 32-bit Windows. Are
you sure that's not the case?
Did you try using the sxstrace tool? Here's good documentation for how to do so

perhaps, this can help:
1) download zip with latest SQLite DLL from http://sqlite.org/download.html;
2) unzip it to c:\temp;

4) if there is already sqlite3.dll in Windows\System32 and it's locked,
