BEGIN

BEGIN is used in SQL to start a transaction, which is a sequence of one or more SQL operations that are executed as a single unit. A transaction ensures that all operations within it are completed successfully before any changes are committed to the database. If any part of the transaction fails, the ROLLBACK command can be used to undo all changes made during the transaction, maintaining the integrity of the database. Once all operations are successfully completed, the COMMIT command is used to save the changes. Transactions are crucial for maintaining data consistency and handling errors effectively.
