SaveTransaction Method
This feature will be removed in a future version of Microsoft SQL Server. Avoid using this feature in new development work, and plan to modify applications that currently use this feature.
The SaveTransaction method marks a point within a transaction, that controls conditional application of the RollbackTransaction method.
Syntax
object
.SaveTransaction(
Savepoint
)
Parts
object
Expression that evaluates to an object in the Applies To list.Savepoint
String naming the transaction midpoint. The string must be valid for use as a Microsoft SQL Server identifier.
Prototype (C/C++)
HRESULT SaveTransaction(SQLDMO_LPCSTR SavepointName);
Remarks
Any open SQL Server transaction can be committed in its entirety, rolled back in its entirety, or rolled back to a midpoint in the transaction identified by the user. Only work within the transaction unit done after the marking of a midpoint is rolled back to the midpoint when a rollback operation is performed naming the midpoint. After rollback to a midpoint, the transaction is considered open and must be closed by either committing work or rolling back the entire transaction.
Each midpoint within a transaction can be named uniquely and then uniquely referenced in a rollback operation. When a midpoint is not named uniquely, a rollback indicating the point affects that work done within the transaction and occurring after the most recent use of the name.
Note
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 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.
