mysql – #1273 – 未知校对：’utf8mb4_unicode_ci’cPanel

2019-09-18 20:15:35 作者：互联网

我在本地计算机上有一个WordPress数据库,我想将其传输到cPanel上的托管phpMyAdmin.但是,当我尝试将数据库导入环境时,我不断收到此错误：

#1273 - Unknown collation: 'utf8mb4_unicode_ci'

我试过谷歌,我能找到的唯一解决方案是这个phpmysql error – #1273 – #1273 – Unknown collation: ‘utf8mb4_general_ci’,现在已经没有多少帮助了.我已经尝试清除cookie但它仍然无法正常工作.请帮忙！

解决方法:

我遇到了同样的问题,因为我们所有的服务器都运行旧版本的MySQL.这可以通过运行PHP脚本来解决.将此代码保存到文件并运行它输入数据库名称,用户和密码,它将从utf8mb4 / utf8mb4_unicode_ci更改为utf8 / utf8_general_ci

<!DOCTYPE html>
<html>
<head>
  <title>DB-Convert</title>
  <style>
    body { font-family:"Courier New", Courier, monospace; }
  </style>
</head>
<body>

<h1>Convert your Database to utf8_general_ci!</h1>

<form action="db-convert.php" method="post">
  dbname: <input type="text" name="dbname"><br>
  dbuser: <input type="text" name="dbuser"><br>
  dbpass: <input type="text" name="dbpassword"><br>
  <input type="submit">
</form>

</body>
</html>
<?php
if ($_POST) {
  $dbname = $_POST['dbname'];
  $dbuser = $_POST['dbuser'];
  $dbpassword = $_POST['dbpassword'];

  $con = mysql_connect('localhost',$dbuser,$dbpassword);
  if(!$con) { echo "Cannot connect to the database ";die();}
  mysql_select_db($dbname);
  $result=mysql_query('show tables');
  while($tables = mysql_fetch_array($result)) {
          foreach ($tables as $key => $value) {
           mysql_query("ALTER TABLE $value CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_ci");
     }}
  echo "<script>alert('The collation of your database has been successfully changed!');</script>";
}

?>
