MySQL IN Operator
The IN operator in MySQL allows you to specify multiple values in a WHERE clause. It is useful when you want to retrieve rows that match any of the specified values.
Example:
SELECT * FROM products WHERE category IN ('Electronics', 'Clothing', 'Furniture');This query will retrieve all products whose category is either ‘Electronics’, ‘Clothing’, or ‘Furniture’.
Using Subquery with IN Operator:
The IN operator can also be used with a subquery to retrieve values from a subquery result.
SELECT * FROM products WHERE price IN (SELECT MAX(price) FROM products);This query will retrieve products with the maximum price from the “products” table.
The IN operator provides a concise way to filter rows based on multiple values in MySQL queries.
