Indeed. Well, my fault. However until @gunter_hick asked, i didn't even realize, that i use 2 different SQLite instances. Hence, i still suppose, that this particular topic should be mentioned in Overview section of LuaSQLite3 Documentation. http://lua.sqlite.org/index.cgi/doc/tip/doc/lsqlite3.wiki#overview *I hope it's not an 'off topic', since lua.sqlite.org is a subdomain of sqlite.org
