Transactions: INSERT, UPDATE, and DELETE

Relational databases support transactions so a group of operations either completes entirely or rolls back. A single write statement also begins and commits implicitly in many simple cases.

Your Task

Insert a new user into the users table with the name Dana, email dana@example.com, and age 26. The query should report that one row was affected.
