An example of an AI chatbot conversation about SQL keys and their usage in databases.
What are some examples of SQL keys?
SQL keys are crucial for identifying records in a database. Examples include Primary Key, Foreign Key, and Unique Key.
Can you explain what a Primary Key is?
A Primary Key is a unique identifier for a record in a table. It ensures that no two rows have the same value in that column.
What about Foreign Keys?
A Foreign Key is a field in one table that links to the Primary Key in another table, establishing a relationship between the two.
Are there any other types of keys?
Yes, there's also the Unique Key, which ensures all values in a column are different, but unlike Primary Keys, it can accept nulls.
