What are the potential issues with using onMouseover in PHP for database column exchange?

Using onMouseover in PHP for database column exchange can lead to security vulnerabilities such as SQL injection attacks if user input is not properly sanitized. To solve this issue, it is important to sanitize user input before using it in SQL queries to prevent malicious code execution. 

// Sanitize user input before using it in SQL query
$column = filter_input(INPUT_GET, 'column', FILTER_SANITIZE_STRING);

// Use prepared statements to prevent SQL injection
$stmt = $pdo->prepare("SELECT * FROM table WHERE column = :column");
$stmt->bindParam(':column', $column);
$stmt->execute();
