The IN operator is used to filter records based on a list of values. It is a simpler way to use multiple OR conditions.

Examples with Tamil Kings

1. Using IN with Multiple Values

SELECT * FROM tamil_kings_auto_increment
WHERE king_name IN ('Raja Raja Chola', 'Rajendra Chola I');

2. Using NOT IN

SELECT * FROM tamil_kings_auto_increment
WHERE king_name NOT IN ('Karikala Chola', 'Vijayalaya Chola');

Best Practices

• Use IN to simplify queries with multiple OR conditions.
• Be mindful of the performance impact when using IN with large lists of values.

Key Takeaways

• The IN operator filters records based on a list of values.
