Loading an extension by a select statement (with the "load_extension" SQLite3 function like above) has some limitations. If you need to, say, create other functions from an extension, use this method. $file (a path to the extension) is mandatory, and $proc (an entry point name) is optional. You need to call C<sqlite_enable_load_extension> before calling C<sqlite_load_extension>. Loading an extension by a select statement (with the "load_extension" SQLite3 function like above) has some limitations.
