BeginTransaction Method
Questa caratteristica verrà rimossa a partire da una delle prossime versioni di Microsoft SQL Server. Evitare di utilizzare questa caratteristica in un nuovo progetto di sviluppo e prevedere interventi di modifica nelle applicazioni in cui è attualmente implementata.
The BeginTransaction method explicitly marks the start of a transaction unit.
Sintassi
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);
Osservazioni
Use the BeginTransaction, CommitTransaction, and RollbackTransaction methods to implement application-defined transaction units.
Nota
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.
