我想做这样的事情：
SET @row_number = 0;
SELECT @row_number := 1 as row_number,* FROM `users`;
我需要的是：
* + row_number
上述声明让我误以为*。
如果我替换所有列名而不是*，那么它可以正常工作。
像这样：
SET @row_number = 0;
SELECT @row_number := 1 as row_number,Id, Name,UserName,LastName FROM `users`;
但我不想输入所有列名。
有没有解决方案？

当你说*时，你必须告诉MySQL你所指的是什么表。
SET @row_number = 0;
SELECT @row_number := 1 as row_number, `users`.* FROM `users`;
或者，您可以切换@row_number和*。
SET @row_number = 0;
SELECT *, @row_number := 1 as row_number FROM `users`;

尝试
SET @row_number = 0;
SELECT @row_number := 1 as row_number,`users`.* FROM `users`;
