This function is deprecated since 6.6. We strongly advise against using it in new code.
Executes a SQL statement on the database and returns a QSqlQuery 对象。使用 lastError () to retrieve error information. If query is empty, an empty, invalid query is returned and lastError () is not affected.
使用 QSqlQuery::exec () 代替。
