Quick Answer
Prepared statements: parse and plan the SQL once, execute many times with different parameters. Security: parameters are sent separately from the query (prevents SQL injection - no string interpolation). Performance: plan is cached in the session. In application code: most drivers use prepared statements by default when you pass parameters. At DB level: PREPARE stmt FROM "SELECT * FROM users WHERE id = ?"; EXECUTE stmt USING @id.
Answer
Prepared statements precompile SQL and prevent SQL injection by separating queries from data.
