An example of an AI chatbot conversation about SQL transaction rollback concepts.
What is a SQL transaction rollback?
A SQL transaction rollback is a command that undoes changes made in a transaction, reverting the database to its previous state.
When would I need to use a rollback?
You would use a rollback if an error occurs during a transaction, or if you decide not to proceed with the changes.
Can you give me an example of how to perform a rollback?
Sure! In SQL, you can use the command ROLLBACK; after a transaction to undo all changes made since the last BEGIN TRANSACTION;.
What happens if I don't use rollback after an error?
If you don't use rollback, the changes made during the transaction will be committed, potentially leading to data inconsistency.
