The IN operator is used to filter data matching any value in a list.
It simplifies multiple OR conditions in a query.
In my project, we used IN to extract orders from specific regions.
It works with numbers, strings, or dates.
IN improves query readability and reduces errors.
It can also be used with subqueries to filter dynamically.
This operator is useful for selective and efficient data extraction.
