BeginTransaction Method

Diese Funktion wird in zukünftigen Versionen von Microsoft SQL Server nicht mehr bereitgestellt. Verwenden Sie diese Funktion beim Entwickeln neuer Anwendungen nicht, und planen Sie das Ändern von Anwendungen, in denen es zurzeit verwendet wird.

The BeginTransaction method explicitly marks the start of a transaction unit.

Syntax

object.BeginTransaction ( [ TransactionName ] )

Parts

• object
  Expression that evaluates to an object in the Applies To list.

• TransactionName
  Optional. A string naming the transaction.

Prototype (C/C++)

HRESULT BeginTransaction(
SQLDMO_LPCSTR szTransactionName = NULL);

Hinweise

Use the BeginTransaction, CommitTransaction, and RollbackTransaction methods to implement application-defined transaction units.

Hinweis

SQL Distributed Management Objects (SQL-DMO) implements objects that can be used to automate Microsoft SQL Server administration. Most administrative functions use data definition language (DDL) statements for their implementation. Generally, application-defined transaction units are not respected by DDL. Where SQL Server does not implement transaction space for DDL, SQL-DMO does not extend DDL by defining a transaction space.

In general, use the BeginTransaction, CommitTransaction, and RollbackTransaction methods only when submitting Transact-SQL command batches for execution by using methods such as ExecuteImmediate. It is suggested that you do not leave transaction units open, but either commit or roll back the unit when the command batch execution method is complete.
