3.7 How to use CASE Statement in SQL | SQL Full Course for Beginners | By Carl Huff

Описание: In this video I will be showing you how to use the CASE Statement.
2023
The CASE expression goes through conditions and returns a value when the first condition is met (like an if-then-else statement). So, once a condition is true, it will stop reading and return the result. If no conditions are true, it returns the value in the ELSE clause.

If there is no ELSE part and no conditions are true, it returns NULL.
