Answer
Use the EXPLAIN statement before your SQL query.
EXPLAIN provides insights into how a database executes a query, showing if indexes are used. This helps optimize query performance. For example, running `EXPLAIN SELECT * FROM products WHERE price > 100` reveals if an index on the 'price' column is utilized.
