You can use ROLLBACK TRANSACTION to erase all data modifications made from the start of the transaction or to a savepoint. It also frees resources held by the transaction. This does not include changes made to local variables or table variables. These are not erased by this statement.
COMMIT permanently saves the changes made by the current transaction. ROLLBACK undo the changes made by the current transaction. 2. The transaction can not undo changes after COMMIT execution.
The ROLLBACK Command This command can only be used to undo transactions since the last COMMIT or ROLLBACK command was issued. Following is an example, which would delete those records from the table which have the age = 25 and then ROLLBACK the changes in the database.
By using Sequence Containers (Sequence, For Loop, ForEach Loop) in SSIS, you can make use of a property called TransactionOption. This allows you to specify the transactional behaviour of the tasks in your package, and the package itself to rollback if any tasks fail.
For example, if you stick your tasks in a Sequence Container and set TransactionOption=Required, and configure all Tasks within the Container to TransactionOption=Supported, they will all join the transaction started in the Sequence Container, and if any fail, the transaction will be rolled back.
You can read an explanation of the TransactionOption property here and/or follow the walkthrough here to see how to implement this.
