Welcome to Practical Session 3 of my Oracle SQL Developer Hands-On series!
In this session, we will work with some very useful SQL commands that help you modify and manage data in your database:
✅ ALTER — to change table structure
✅ UPDATE — to update data in your tables
✅ DELETE — to remove data
✅ COMMIT — to permanently save changes
✅ ROLLBACK — to undo uncommitted changes
We’ll be continuing with the students table from the previous session — and practice each command step-by-step with clear examples.
This is a great practical session for beginners and testers who want to build confidence in writing SQL queries for real-world scenarios.
