Hello World!
Welcome to the channel "CodeWithAbby". I am from INDIA and make videos of different technical topics. These videos are made based on my research and idustry experience of more than 20 years.
I am going to cover the below topics in this video:
1. What is the importance of SQL constraints
2. Why do we need SQL constraints ?
3. What are all SQL constraints available
4. Detailed explanation of each one of them
5. NOT NULL, UNIQUE, PRIMARY KEY , FOREIGN KEY, DEFAULT, CHECK, INDEX,
6. Explaining master table and transaction table
7. Explaining how ON DELETE CASCADE works
At the end of this session , you would be able to build your understanding on creating any kind of constraints on table and fieds. This is going to help you design your DB efficiently to provide integrity, efficienty and consistency.
Stay tuned....
Stay updated!
Regards,
Abby
