Nesting allows one
transaction
to initiate other transactions. These nested transactions are
initiated using the Begin(
) method of the
Transaction object, which returns a reference to a
new transaction object. However, rolling back this transaction rolls
back only the nested transaction and not the entire transaction.
Nested transactions aren't supported by the SQL
Server .NET data provider although savepoints can be used with that
data provider to accomplish a similar result. The OLE DB provider for
SQL Server also doesn't support nested transactions.
