38 -# by passing KDbQuerySchema object to KDbConnection::executeQuery() or KDbConnection::prepareQuery();
41 -# by passing raw query statement string to KDbConnection::executeQuery() or KDbConnection::prepareQuery();
49 The cursor can also be positioned after the last record (if any) with moveNext() -- then eof() equals true.
64 - Do not use delete operator for KDbCursor objects - this will fail; use KDbConnection::deleteCursor()
