JetBeginTransaction3 Function

Windows

Last modified: October 25, 2012

Applies to: Windows | Windows Server

The JetBeginTransaction3 function causes a session to enter a transaction and create a new save point. This function can be called more than once in a single session to create additional save points. These save points can be used to selectively to keep or discard changes to the database.

The JetBeginTransaction3 function was introduced in the Windows 8 operating system.

JET_ERR JET_API JetBeginTransaction3(
  __in          JET_SESID sesid,
  __in          int64 trxid,
  __in          JET_GRBIT grbit
);

Parameters

sesid

The session to use for this call.

trxid

An optional identifier supplied by the user to identify the transaction.

grbit

A group of bits that that specifies zero or more of the call option values listed in the following table.

Value

Meaning

JET_bitTransactionReadOnly

The transaction will not modify the database. If an update is attempted, that operation will fail with JET_errTransReadOnly response code. This option is ignored unless it is requested when the given session is not already in a transaction. This option is available in versions of the Windows operating system starting with Windows XP.

Return value

This function returns the JET_ERR data type with one of the return codes listed in the following table. For more information about the possible Extensible Storage Engine (ESE) errors, see Extensible Storage Engine Errors and Error Handling Parameters.

Return code

Description

JET_errSuccess

The operation completed successfully.

JET_errClientRequestToStopJetService

It is not possible to complete the operation because all activity on the instance associated with the session has ceased as a result of a call to the JetStopService function.

JET_errInstanceUnavailable

It is not possible to complete the operation because the instance associated with the session has encountered a fatal error that requires that access to all data be revoked to protect the integrity of that data.

This return code is returned by versions of Windows starting with Windows XP.

JET_errNotInitialized

It is not possible to complete the operation because the instance associated with the session has not been initialized yet.

JET_errRestoreInProgress

It is not possible to complete the operation because a restore operation is in progress on the instance associated with the session.

JET_errSessionSharingViolation

The same session cannot be used for more than one thread at the same time. This error is returned by versions of Windows starting with Windows XP.

JET_errTermInProgress

It is not possible to complete the operation because the instance associated with the session is being shut down.

JET_errTransTooDeep

A new transaction cannot be started because the session is already at the maximum save point depth allowable by the database engine.

On success, the provided session will be inside a transaction. If the session was previously inside a transaction, a new save point will be created.

On failure, the transactional state of the session will remain unchanged. No change to the database state will occur.
