Please do not submit the same bug more than once. An existing bug report already describes this very problem. Even if you feel that your issue is somewhat different, the resolution is likely to be the same. Because of this, we hope you add your comments to the original bug instead. Thank you for your interest in MySQL. Duplicate of Bug #27210

No, this is not a duplicate of #27210. This is a very different bug which is present in all versions of mysql and with all storage engines.

This is definitely not a bug. The statement is called INSERT ... ON DUPLICATE KEY UPDATE. Its semantic is: 1. try to insert a row. 2. if the insert operation returns an error "DUPLICATE KEY" perform update. Apparently the customer needs a different semantics: 1. try to insert a row. 2. if the insert operation returns ANY errorperform update.
