但是,如果在执行插入语句时数据库内部抛出了"ORA-1403: no data found"错误,那么数据库就不会返回新的行ID。这就导致了"DatabaseError: The database did not return a new row id. Probably 'ORA-1403: no data found' was raised internally but was 'hidden by the Oracle OCI library '."错误。如何解决解决"DatabaseError: The database did not return a new row id. Probably 'ORA-1403: no data found' was raised internally but was 'hidden by the Oracle OCI library '."错误的关键是要找出导致"ORA-1403: no data found"错误的原因,并修改你的代码使其不再导致这个错误。
