Mysql + QT
Very simple an SQL statement
Sprintf (buff, "delete from fuel_log where id=% d", slt_id);
Prompt deleted successful operation, also can not query delete records, after I shut down the software, in the open again, again query, delete data remains strong,
Delete, again a second time before geodesic remove out of the database,
Sometimes one can delete, really confused,,,
The younger brother new to this, I don't know whether to submit enforcement order? How to solve this problem,? Thank you for your attention

This operation: add a new record, and then deleted, can appear the above situation,
But if: after add records, close the connection and the software, the restart software, and deleting records, so that we can, why?
