What are the potential pitfalls of not specifying the order in a MySQL query?

When the order is not specified in a MySQL query, the results may be returned in an unpredictable order, leading to inconsistent or incorrect data being displayed to the user. To avoid this issue, always specify the desired order using the ORDER BY clause in your SQL query.

$query = "SELECT * FROM table_name ORDER BY column_name ASC";
$result = mysqli_query($connection, $query);

if($result){
    while($row = mysqli_fetch_assoc($result)){
        // Process the data
    }
} else {
    echo "Error: " . mysqli_error($connection);
}

mysqli_close($connection);
