Remarks

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

Note  SQL-DMO implements objects that can be used to automate Microsoft® SQL Server™ 2000 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.
