WordPress的DB錯誤：多個主鍵定義

當我嘗試激活我的自定義插件，我收到以下錯誤：WordPress的DB錯誤：多個主鍵定義

WordPress database error Multiple primary key defined for query ALTER TABLE temp CHANGE COLUMN id id int(11) UNSIGNED AUTO_INCREMENT PRIMARY

private function runDbMigration_20() { 
    $sql = "CREATE TABLE " . PREFIX . "subscribers (
    id int(11) UNSIGNED AUTO_INCREMENT PRIMARY KEY,  
    name tinytext NOT NULL, 
    email text NOT NULL, 
      secretkey text NOT NULL,

      onedaymailsent int(1) NOT NULL DEFAULT 0, 
      wbstartingmailsent int(1) NOT NULL DEFAULT 0, 
      replaymailsent int(1) NOT NULL DEFAULT 0, 
      temp_id int(11) NOT NULL,

      attended int(1) UNSIGNED NOT NULL DEFAULT 0 
)" . $this->CHARSET_COLLATE . ";"; 
    return $this->calldbDelta($sql); 
}

請，能有人幫助我如何解決這個問題？

問題是不是在你引用的代碼出現。該問題似乎與「ALTER TABLE」（而不是「CREATE TABLE」）和TEMPORARY表（不是永久的）有關。你的MySQL服務器記錄查詢和/或你能找到代碼在臨時表上調用ALTER TABLE的位置嗎？ – barrycarter

感謝您糾正我。我將在MYSQL服務器上啓用日誌查詢，並將查找ALTER TABLE代碼所在的路徑@barrycarter – Himani

添加PRIMARY KEY（ID）最後解決錯誤
