使用 UNION ALL 查询在 FROM 子句中出现语法错误

Question

我有一个 Union All 查询，我目前正在从中运行生成表查询。我试图将它们合并为一件事，并让联合所有查询也只是制作表格。我在这里动态学习，任何人都在尝试 INTO 方法，我可以将其作为一个生成表来工作，但是一旦我添加 UNION ALL，我就会得到语法错误。

对我做错的任何帮助将不胜感激。

MS Access 用所有荒谬、无用的括号来制造噩梦。如果您将查询复制到文本编辑器中，例如免费的 Notepad++，它会突出显示开始和结束分隔符，这将使这样的工作变得更加容易。

我不知道这是否会做你想做的事，但它应该会清除你当前遇到的语法错误。
