Re: Transaction ISOLATION LEVEL - have I missed something?

Hi David, and thanks for getting back to me.

Ah, yes, it now makes perfect sense...

All statements in a transaction which is READ COMMITTED sees the data
as of CLOCK_TIMESTAMP() and all statements in a transaction that is
SERIALIZABLE see the data as of TRANSACTION_TIMESTAMP().

At least, that's how I understand it now - my error was not
double-checking my function definitions.
