Question

我有此查询，该查询使用联接从主数据库和用户数据库的主表中提取数据。

SELECT 
  `user_details`.`id` AS `masterid`, 
  `user_details`.`emailaddress`,
  `user_details`.`is_login` as `userstate`, 
  `user_details`.`fullname` as fullname, 
  `user_details`.`securitytemplate`, 
  `user_details`.`registered`, 
  `user_details`.`isactive`, 
  `users`.`id` AS `userid`,
  `users`.`profilepicture` AS `userpic`,
  security.templatename 
FROM 
  (SELECT * FROM `gs_master`.`user_details` 
  WHERE `gs_master`.`user_details`.`db_identifier`= 136) AS `user_details` 
  LEFT JOIN gs_db_136.`users` 
    ON `user_details`.`emailaddress` = `users`.`email` 
  JOIN gs_db_136.`security_templates` AS security 
    ON security.id = `gs_master`.`user_details`.securitytemplate 
ORDER BY 
  fullname ASC

奇怪的是它在我的Centos机器上运行，但不会在我的本地主机上运行。我已经更新了数据库，并且所有表都存在。如果直接在localhost表上查询，则会得到结果，所以我不确定是否会是什么？我猜这一定与不同机器上允许的语法有关吗？

我得到的错误是：

＃1054-“子句”中的未知列“ gs_master.user_details.securitytemplate”

任何帮助，我们将不胜感激。

这可能是您尝试获得的：

SELECT 
  `user_details`.`id` AS `masterid`, 
  `user_details`.`emailaddress`,
  `user_details`.`is_login` as `userstate`, 
  `user_details`.`fullname` as fullname, 
  `user_details`.`securitytemplate`, 
  `user_details`.`registered`, 
  `user_details`.`isactive`, 
  `users`.`id` AS `userid`,
  `users`.`profilepicture` AS `userpic`,
  security.templatename 
FROM 
  (SELECT * FROM `gs_master`.`user_details` 
  WHERE `gs_master`.`user_details`.`db_identifier`= 136) AS `user_details` 
  LEFT JOIN gs_db_136.`users` 
    ON `user_details`.`emailaddress` = `users`.`email` 
  JOIN gs_db_136.`security_templates` AS security 
    ON security.id = `user_details`.securitytemplate 
ORDER BY 
  fullname ASC

查询不会在本地主机上运行
