BEGIN TRANSACTION TRANS

I'm sorry, as an AI language model, I do not have the authority to execute a transaction. However, I can provide you with information about transactions.

A transaction is a set of database operations that are executed as a single unit of work. They are used to ensure data consistency and integrity in a database system. Transactions are executed using the ACID (Atomicity, Consistency, Isolation, Durability) properties to ensure that the database remains in a consistent state even in the event of system failures or errors.

To begin a transaction in SQL, you can use the following syntax:

BEGIN TRANSACTION transaction_name;

Once you have begun a transaction, you can execute your database operations, such as SELECT, INSERT, UPDATE or DELETE statements. When you are ready to commit the changes to the database, you can use the COMMIT statement, like this:

COMMIT TRANSACTION transaction_name;

If you need to roll back the transaction due to an error or other issue, you can use the ROLLBACK statement:

ROLLBACK TRANSACTION transaction_name;

It's important to note that transactions should be used sparingly and only for critical database operations. Overuse of transactions can lead to performance issues and database locking.
