An example of an AI chatbot conversation about foreign keys in databases.
What are some examples of foreign keys in databases?
Foreign keys are used to link tables in a relational database. For example, in a database with a 'Customers' table and an 'Orders' table, the 'Orders' table might have a foreign key that references the 'CustomerID' in the 'Customers' table.
Can you give me another example?
Sure! In a 'Students' table and a 'Courses' table, the 'Courses' table could have a foreign key that references 'StudentID' from the 'Students' table, indicating which student is enrolled in which course.
How do foreign keys enforce referential integrity?
Foreign keys ensure that the value in the referencing table matches a value in the referenced table, preventing orphaned records.
What happens if a foreign key constraint is violated?
If a foreign key constraint is violated, the database will reject the operation that caused the violation, ensuring data integrity.
