What common syntax errors should PHP developers be aware of when writing database queries?

One common syntax error that PHP developers should be aware of when writing database queries is forgetting to properly escape input data to prevent SQL injection attacks. This can be solved by using prepared statements with placeholders for dynamic data. Another common error is not properly handling errors or exceptions that may occur during the query execution. 

// Example of using prepared statements to prevent SQL injection
$stmt = $pdo->prepare("SELECT * FROM users WHERE username = :username");
$stmt->bindParam(':username', $username);
$stmt->execute();
