<para>

This level is different from Read Committed in that a query in a

repeatable read transaction sees a snapshot as of the start of the

first non-transaction-control statement in the

<emphasis>transaction</>, not as of the start

of the currentquery within the transaction. Thus, successive

of the currentstatement within the transaction. Thus, successive

<command>SELECT</command> commands within a <emphasis>single</>

transaction see the same data, i.e., they do not see changes made by

other transactions that committed after their own transaction started.
