Re: Deadlocks on inserts to the same table

Radu,

at a duplicate key error we must take a lock on the duplicate, because you have received information from the server that there is a duplicate row in the database. In locking, all information that you receive from the server must be protected with locks, the state in the server must be kind of 'frozen', so that you can trust it until you commit the transaction.

Best regards,

Heikki
