What are the potential pitfalls of using dynamic SQL queries in PHP scripts for updating database records?

Using dynamic SQL queries in PHP scripts for updating database records can lead to SQL injection vulnerabilities if user input is not properly sanitized. To prevent this, it is important to use prepared statements with parameterized queries to ensure that user input is treated as data and not executable code. 

// Using prepared statements to update database records safely
$stmt = $pdo->prepare("UPDATE table SET column = :value WHERE id = :id");
$stmt->bindParam(':value', $value);
$stmt->bindParam(':id', $id);
$stmt->execute();
