The better you understand how to use them, the more effectively you can ensure the integrity of your data. Transactions are an invaluable tool when trying to maintain data consistency and reliability across your database. Although the examples are fairly basic, they should help you understand what it takes to create a transaction and what types of behavior you can expect. To this end, I provide you with several examples that demonstrate how MySQL transactions work and why they’re important. The purpose of this article is to introduce you to the basics of transactions, so you have a better understanding of how to get starting using them when writing your SQL code. There are many aspects to transactions, however, far more than can be covered adequately in a single article.

Transactions play a pivotal role in ensuring the integrity of MySQL data, which is why database developers should have a good foundation in how they work. Otherwise, MySQL commits the changes to the database and then terminates the transaction. If any statements within a transaction fail or do not achieve their desired results, the changes can be rolled back and the database returned to its original state, as it existed prior to starting the transaction. MySQL transactions provide an effective method for executing multiple statements as a single unit, making it possible to safely modify data, while preventing concurrent users from updating the same data or overwriting changed data.
