How to implement Transactions (COMMIT / ROLLBACK) using SQL SERVER.

preview_player
Показать описание
In this video, I will introduce transactions in SQL server. We will learn about how to recover your data using the ROLLBACK command, how to save your changes permanently to the database using the transaction COMMIT command.

We will look at how BEGIN TRANSACTION affects other users, and how SQL Server has given us some tools to work around these obstacles.

Show example of the Dirty Read situation.
