When using DATE_FORMAT in MySQL queries, what are some common pitfalls to avoid?

When using DATE_FORMAT in MySQL queries, one common pitfall to avoid is not properly escaping the date format string. This can lead to SQL injection vulnerabilities. To solve this issue, always use prepared statements with placeholders for the date format string. 

// Avoid SQL injection by using prepared statements with placeholders for DATE_FORMAT
$dateFormat = "Y-m-d";
$stmt = $pdo->prepare("SELECT DATE_FORMAT(date_column, :format) FROM table_name");
$stmt->bindParam(':format', $dateFormat);
$stmt->execute();
