SQL Server – ROLLBACK TRANSACTION

It is used to rollback the last transactions, if transactions not commit.

Syntax:

ROLLBACK;

Let’s understand with an example:

Step 1: Sample data as below:

Step 2: Now, delete all records from Students Table using BEGIN TRAN command.

Query:

BEGIN TRAN T1
DELETE Students
--T1 : is Transaction name
--Execute both query together

Step 3:  Now all records has been deleted.

SELECT * FROM Students

Step 4: But we used BEGIN TRAN before SQL Query statement, so it holds the transaction until the transaction is either committed or rolled back.

Step 5:  Now we rolled back the Transaction.

ROLLBACK TRAN T1

Step 6: check again the table all records rolled back or not?

SELECT * FROM Students

As you saw, all records rolled back successfully!
