Anyone knows where I could download the precompiled binary of version 3.3.4

Hi !
I'm getting a lots of "database is locked" (code:5).
My app keeps giving up on one machine, it might be that
there is a network problem but I not 100% sure.
Anyway, when the app hangs all the other machines
including the machine where the database file is get

Mark,
Actually this wasn't broached at that time, because when the

stored as strings, so it was natural to

Hi all,
I *think* that sqlite3_close behave strangly.
I use version 3.3.7 on Linux (Fedora Core 5).
What I do is to open a database, and start a transaction in it. Then,
without ending the transaction, open again the database and simply close it.
I found out, that the inner sqlite3_close

As far as I know, all technologies which transfer data between machines
(e.g. RPC), languages (e.g. JNI) or wear the cross platform crown (e.g.
SQLite) have some sort of data definition.

I made a database of little pictures, which includes x und y coordinates and
a blob (between 100 and 8000 bytes in size, one blob, total db size 180MB).

I hackish method might be something like this:
struct s
{
...
};
struct s myS;
char buf[sizeof(s)*2]; // *2 as base64 encoding will be approx 33% bigger.
base64_encode( , buf, sizeof(s) );
INSERT INTO table ( myTextField ) VALUES ( 'buf' );
then retrieval is the opposite.
