Parameters use &#8220;?&#8221; as a placeholder, and when executing the pre-processing statement, specific parameter values are passed in. For example:<\/p>\n<pre class=\"post-pre\"><code>PREPARE stmt FROM 'SELECT * FROM customers WHERE id = ?';\r\nEXECUTE stmt USING @customer_id;\r\n<\/code><\/pre>\n<p>In the above example, stmt is the name of the prepared statement and @customer_id is the value of the parameter.<\/p>\n<p>By using prepared statements, SQL injection attacks can be avoided, increasing the security of SQL statements.
