What is a rollback in SQL?
An example of an AI chatbot conversation about rollback operations in SQL databases.
What is a rollback in SQL?
A rollback in SQL is a command used to undo transactions that have not yet been saved to the database.
When would I need to use a rollback?
You would use a rollback if an error occurs during a transaction, or if you want to discard changes made during a session.
Can you give me an example of how to use rollback?
Sure! If you start a transaction with BEGIN TRANSACTION, make some changes, and then decide to undo them, you can use ROLLBACK to revert those changes.
Is there a way to see what changes would be rolled back?
Yes, you can use the SAVEPOINT command to set a point in your transaction. You can then roll back to that point instead of the entire transaction.
