Hello,

I am not really familar with Macstuff.
In Qt there is something like qDebug. QDebug sends Debugmessages
to stderr. Perhaps you start sqlitebrowser from the commandline

If you haven't already, go to the bottom of the main
page at sqlite.org and click on the link to the wiki;
then click on contents.

Hi,
not but you could ask there:
www.qtforum.org.
SqliteBrowser is written with the Qt toolkit. So the people there
will help you.
There are also a few guys from the
correct example:
##
F::FSqlite sql;
sql.sqliteConnect( "testdb" );
sql.sqliteQuery( "SELECT * FROM table" );
while( mySqlObject.dataSetIsLeft( ) ) {
cout << sql.result[ "col_1" ]
cout << sql.result[ "col_2" ]
}
Is anyone aware of a web-based admin utility for SQLite similar to
phpMyAdmin? I found one...
.http://sqlitemanager.sourceforge.net/
...but it is not in English and doesn't look very impressive.

Hello,
perhaps you know: At the moment I am developing a CGI framework
with C++. Now I have implemented a sqlite class. You can do
something like this:
##
F::FSqlite sql;
sql.sqliteConnect( "testdb" );
sql.sqliteQuery( "SELECT * FROM table" );

Same thing:
SELECT * FROM tbl ORDER BY random() LIMIT 1;
works for me.

That will make it O(NlogN) instead of O(N**2).
