How do I use rollback in SQL?
An example of an AI chatbot conversation about using rollback in SQL to undo transactions.
How do I use rollback in SQL?
You can use the ROLLBACK statement to undo transactions in SQL. It reverts the database to the last committed state.
Can you give me an example of how to use it?
Sure! If you start a transaction with BEGIN TRANSACTION, you can execute some SQL commands, and if you want to undo them, just use ROLLBACK;.
What happens if I don't use rollback?
If you don't use ROLLBACK, any changes made during the transaction will be permanently saved once you issue a COMMIT.
Are there any scenarios where I shouldn't use rollback?
Yes, if you are sure that the changes made are correct and you want to keep them, you should use COMMIT instead.
