Answer
PreparedStatements use query plan caching to improve performance.
PreparedStatements can significantly boost database performance by allowing the database to cache the query plan. This means that the database doesn't need to recompile the SQL statement each time it's executed, saving time and resources. For example, if you use a PreparedStatement to repeatedly execute a query like 'SELECT * FROM products WHERE category =?', the database can reuse the compiled plan for each execution, even if the parameter changes, leading to faster query execution.
