Cancels all updates, insertions, and deletions for the current transaction and ends the transaction.
Call Rollback to cancel all updates, insertions, and deletions for the current transaction and to end the transaction. The current transaction is the last transaction started by calling StartTransaction.
Note: Before calling Rollback, an application may check the status of the InTransaction property. If an application calls Rollback and there is no current transaction, an exception is raised.
Note: ReadCommitted isolation level is used in multi-user mode.
