错误：SQLSTATE [42S22]：找不到列：1054 CakePHP

Question

我一直在搜索我尝试访问CakePHP烘焙页面时出现的问题的一些答案，而且我仍然收到此错误：

错误：SQLSTATE [42S22]：未找到列：1054未知列＆＃39;方坯。 USER_ID＆＃39;在＆＃39;字段列表＆＃39;

这是Cake创建的查询

SELECT `Billet`.`id` AS `Billet__id`, 
`Billet`.`created` AS `Billet__created`, 
`Billet`.`updated` AS `Billet__updated`, 
`Billet. user_id` AS `Billet__ user_id`,
`Billet`.`title` AS `Billet__title`, 
`Billet`.`tags` AS `Billet__tags`, 
`Billet`.`content` AS   `Billet__content`, 
`Users`.`id` AS `Users__id`, 
`Users`.`username` AS `Users__username`, 
`Users`.`password` AS `Users__password`, 
`Users`.`name` AS `Users__name`,
`Users`.`lastname` AS `Users__lastname`, 
`Users`.`birthdate` AS `Users__birthdate`, 
`Users`.`email` AS `Users__email` FROM `billet`
`Billet` INNER JOIN `users` `Users` ON `Users`.`id` = (`Billet. user_id`) LIMIT 20 OFFSET 0

执行查询的代码由Cake直接烘焙，因此我没有任何行显示查询是如何完成的。

Answer 1

您在此行上缺少刻度线，并且AS名称中有一个额外的空格：

`Billet. user_id` AS `Billet__ user_id`,

应该是

`Billet`.`user_id` AS `Billet__user_id`,

这一行也是如此：

`Billet` INNER JOIN `users` `Users` ON `Users`.`id` = (`Billet. user_id`) LIMIT 20 OFFSET 0

应该是

`Billet` INNER JOIN `users` `Users` ON `Users`.`id` = (`Billet`.`user_id`) LIMIT 20 OFFSET 0
