Follow the video method: -> field(['name' => "name", 'salary'] ) will prompt an unsupported data expression. If you change "name" to English or use "field('name as name" , salary')" there is no problem. May I ask what is the reason?

You can set the alias directly using a string

Well, there is no problem with the string, but there is a problem with the array mode setting. After looking at it, it seems to be a problem with the framework source code. The regular expression only filters English characters. Later put the framework in library/think/db/build/Mysql.php This line in: if ($strict && !preg_match('/^[\w\.\*]+$/', $key)) { Changed to: if ($strict && !preg_match('/^[\x{4e00}-\x{9fa5}\w\.\*]+$/u', $key)) { That's it.

But in your video tutorial, there is no problem if you use arrays directly. I don’t know how you set it up :)
