嗨我这个代码有问题。首先不工作，但第二个是，我认为问题在于左（）与作为任何人都可以帮助我如何解决它？谢谢： - ）

Answer 1

尝试使用不同的别名

SELECT Left(Code,3) As Code_new, Count(Left(Code,3)) As CPC 
INTO newtable 
FROM TEST  
GROUP BY Left(Code,3)

Answer 2

问题是您的第一列没有column name。您需要提供一些名称，您无法创建没有列名称的表

SELECT Left(Code,3) as L_CODE, Count(Left(Code,3)) As CPC 
INTO newtable 
FROM TEST  
GROUP BY Left(Code,3)
