What happens when you do a SQL query where the IN clause is empty?

For example:

Will MySQL

Answer 1

If you are using that query in an application and you pass dynamically a list of objects to the query, I should not call to the database to do a select with an impossible value, I should return an empty list without calling to the database query, directly.

Because it has no sense to do a query that you know that is empty before calling it.
