ITransaction::Abort

OLE DB Programmer's Reference

Aborts a transaction.

HRESULT Abort(    BOID    *pboidReason,    BOOL     fRetaining,    BOOL     fAsync);

Parameters

pboidReason: [in]
A pointer to a BOID that indicates why the transaction is being aborted. If this is a null pointer, no reason is provided.
fRetaining: [in]
Whether the abort is retaining or nonretaining.
Note A retaining commit or abort should not change the characteristics (isolation level, isolation flags, transaction options) of the transaction. The new unit of work retains the same characteristics as the committed work.
fAsync: [in]
When fAsync is TRUE, an asynchronous abort is performed and the caller must use ITransactionOutcomeEvents to learn the outcome of the transaction.

Return Code

S_OK: The transaction was successfully aborted.
XACT_S_ABORTING: An abort operation was already in progress. This call was ignored.
XACT_S_ASYNC: An asynchronous abort was specified. The abort operation has begun, but its outcome is not yet known. When the transaction is complete, notification will be sent by ITransactionOutcomeEvents.
E_FAIL: The transaction failed to abort for an unspecified reason.
E_UNEXPECTED: An unexpected error occurred. The transaction status is unknown.
XACT_E_ALREADYINPROGRESS: A commit operation was already in progress. This call was ignored.
XACT_E_CANTRETAIN: A retaining abort is not supported, or a new unit of work could not be created. The abort succeeded, and the session is in auto-commit mode.
Abort was called on a distributed transaction with fRetaining set to TRUE.
XACT_E_CONNECTION_DOWN: The connection to the transaction manager failed. The transaction state is unknown.
XACT_E_INDOUBT: The transaction status is in doubt. A communication failure occurred, or a transaction manager or resource manager has failed.
XACT_E_NOTRANSACTION: The transaction cannot be aborted because it already had been implicitly or explicitly committed or aborted. This call was ignored.
XACT_E_NOTSUPPORTED: fAsync was TRUE on input, and asynchronous abort operations are not supported.

Comments

The following table shows how the values of fRetaining and DBPROP_ABORTPRESERVE affect the rowset state and transaction mode.

DBPROP_ABORTPRESERVE	fRetaining	Rowset state after abort	Resulting transaction mode of session
FALSE	FALSE	zombie	implicit/auto-commit
FALSE	TRUE	zombie	explicit/manual-commit
TRUE	FALSE	preserved	implicit/auto-commit
TRUE	TRUE	preserved	explicit/manual-commit
