你可以QSqlQuery::size()用来获取行QSqlRecord::count()数和列数：
QSqlQuery qry;
qry.prepare("SELECT * FROM someTable");
qry.exec();
qDebug() << "Number of Rows: " << qry.size();
qDebug() << "Number of columns: " << qry.record().count();

Mamba is a new state space model architecture showing promising performance on information-dense data such as language modeling, where previous subquadratic models fall short of Transformers. It is based on the line of progress on structured state space models, with an efficient hardware-aware design and implementation in the spirit of FlashAttention.
