MySQL - 不能按值排序

Question

所以我想在数据库中从最高到最低排序值。 它现在唯一能做的就是随机加扰所有结果，这意味着它只会在中间放置100以下，在顶部放置1。

<?php
$con=mysqli_connect("localhost","username","password","table");
// Check connection
if (mysqli_connect_errno()) {
  echo "Failed to connect to MySQL: " . mysqli_connect_error();
}

$result = mysqli_query($con,"SELECT * FROM playerdata ORDER BY Gold");

while($row = mysqli_fetch_array($result)) {
  echo $row['Username'];
  echo " " . $row['Gold'];
  $row['Unique_ID'];
  echo "<br>";
}

mysqli_close($con);
?>

Answer 1

SELECT * FROM playerdata ORDER BY Gold DESC

Answer 2

Mysql不按值排序，但 Mysql根据类型按值排序。 如果我们举个例子：您的表格TABLE1包含两列C1和C2，C1为INT且C2为{ {1}}我们有一套：

VARCHAR

所以

C1    C2
1     1
2     2
10    10

显示

SELECT * from TABLE1 ORDER BY C1 DESC

但

C1    C2
10    10
2     2
1     1

将显示

SELECT * from TABLE1 ORDER BY C2 DESC

因此请注意您的架构和数据。
