Hello Everyone !
Welcome to the channel "Code With Abby". "CodeWithAbby" is the one stop solution for all your technical needs. I (at Code With Abby) 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.
This is one video from the series Tuesday Talks With Abby. In this video I am going to discuss with you one important questions asked by Google. The question is What is the purpose of the FOREIGN KEY constraint in SQL? How does it ensure data integrity?. I am also going to answer the follow up question i.e. What are ON DELETE and ON UPDATE actions in a FOREIGN KEY? Explain with examples.
