GCP Bigquery 导致无法识别的名称和不明确的列

Question

我对 SQL 有疑问，非常感谢您的帮助。我有一个 SQL，这实际上很好用。不幸的是，运行时会创建一个新列。这是自动创建的，称为“Material_1”。这导致无法再调用普通列“Material”（“歧义名称错误”）。但是，如果我 select Material_1，我会得到另一个错误：“无法识别的名称”是指 Material 吗？我非常强烈地认为排名与它有关，但我尝试将它从 >1 设置为 >=2 或类似的小调整没有成功。

Answer 1

empf.* EXCEPT (Faktura_Key) 这导致了错误。 f.Material AS empf_Material 解决了问题
