An example of an AI chatbot conversation about SQL data validation techniques.
How can I validate data in SQL before inserting it into a database?
You can use constraints like NOT NULL, UNIQUE, and CHECK to validate data in SQL. Would you like examples?
Yes, please provide examples of these constraints.
Sure! A NOT NULL constraint ensures a column cannot have a NULL value. A UNIQUE constraint ensures all values in a column are different. A CHECK constraint allows you to specify a condition that must be met for the data to be valid.
Can I use triggers for data validation as well?
Absolutely! Triggers can be used to enforce complex validation rules before data is inserted or updated.
