Let me repeat that, because I know it is a very common mistake. That does *NOT* work. The only thing that will protect you from a phantom read is a transaction with the isolation level "serializable". According to the relevant standards, transactions should default to the isolation level "serializable" and you should be right. However, most databases default to "read committed", and therefore will not protect you from phantom reads. Explicitly adding isolation="serializable" is required.
