SYMPTOMS

Consider the following scenario. You use the SQL Native Client OLE DB provider to connect to an instance of Microsoft SQL Server 2005 in an application. In the connection, you start a transaction that enables the xact_abort option. After the option in enabled, SQL Server rolls back the transaction if a deadlock or an integrity violation occurs. Then, you try to abort the transaction. To do this, you call the ITransactionLocal::Abort method by setting the fRetaining flag of the ITransactionLocal::Abort method to TRUE.

In this scenario, you expect a new transaction to start in manual-commit mode after you abort the current transaction. Therefore, you expect that you can roll back the later TRANSACT-SQL statements after you call the ITransactionLocal::Abort method. However, you cannot roll back the later statements.

CAUSE

This issue occurs because the SQL Native Client OLE DB provider incorrectly switches the commit mode of the connection from manual-commit to auto-commit. Therefore, any changes in the later TRANSACT-SQL statements are immediately committed.
