Everything you need to safely test, rollback, and commit changes — just like a pro.

🧠 Why This Matters

Ever accidentally deleted or updated critical production data?

Backups are great, but they take time. What if you could instantly undo your last change?

That’s where Transactions, Savepoints, and Implicit Transactions come in.

🔹 What Is a Transaction?

A Transaction is a logical unit of work. It ensures either all changes happen, or none do — keeping your data consistent and safe.

Basic commands:

• BEGIN TRANSACTION
• ROLLBACK TRANSACTION
• COMMIT TRANSACTION

✅ Safe Delete Template

Copy this template before executing any risky DELETE/UPDATE:

BEGIN TRANSACTION;

-- Step 1: Preview
SELECT * FROM YourTable WHERE <your-condition>;

-- Step 2: Delete or update
DELETE FROM YourTable WHERE <your-condition>;

-- Step 3: Check how many rows were affected
SELECT @@ROWCOUNT AS RowsAffected;

-- Step 4: Decision time!
-- COMMIT TRANSACTION;   -- Everything's good
-- ROLLBACK TRANSACTION; -- Oops, undo!

📝 Replace YourTable and <your-condition> with your query.
