我正在尝试在访问中运行查询，但我不断收到一条错误消息，阻止我运行它。是查询太大还是我的电脑太慢了？这是一台非常旧的计算机，所以我认为这是最有可能的情况，也是戴尔。当我不选择 DISTINCT 时查询有效，但当我选择时查询无效。但是，我得到了太多重复，所以我需要 DISTINCT。

错误信息

无法完成查询。查询结果的大小大于数据库的最大大小（2GB）或者磁盘上没有足够的临时存储空间来存储查询结果

(1) 当您在 Access 查询设计器中进行查询时，您必须在表之间画一条线以通过主键连接它们。哪个，我猜你不能去，因为...

(2) 导入数据的方式对数据库模式没有意义。一方面，它们的方式（每个表一项研究，我猜是“名称”字段）与设计合理的数据库相距甚远，以至于毫无用处。

例如，30 多个这样的表：

  • 表名=[研究的名称]
    由特定数据项命名的表是设计错误的死板。您应该能够在不更改表结构的情况下输入新数据。因此，数据库表更贴切地以其中的数据类型命名
  • 表包含：铂。名字，（其他东西）。没关系。

(3) 另一方面，它应该是非常简单的。您不需要任何连接。

  • 一张名为 StudyParticipants 的表。
  • 2+ 字段：StudyName、Pt_Name、（其他字段）
  • [如果你真正开始编程，你会有其他表格，例如，'studies'等]

(4) 我猜这样的设计不是因为你想要那样，而是因为这就是导入的方式。您可能有一个电子表格，每个研究都有一个标签。我也可以说出来，因为名字字段略有不同。

如果你想使用数据库，那是行不通的。你最好写一个宏来循环你的excel表。

(5) 如果要正确导入，则必须先创建一个表，其中的列与任何工作表上所有可能的列匹配。然后，您必须一次导入一张工作表，每次发生时，对于与工作簿中工作表的选项卡名匹配的整个工作表的数据库的 StudyName 字段。

一个可悲的预测，这是真的。

当然，在执行所有这些操作之前，您可以创建一个查询，尝试将它们全部合并到一个大表中（使用 AS 子句将不同的名称字段重命名为一个），然后在 union'd 上运行查询看法。

评论太大了：

我正在努力寻找看起来像这样返回的结果的含义：

[ECOG 2809 ICORG 11-04].Title   [Anti-Mullerian AMH_SVU_1].Name [Tarceva Biomarker ICORG 11-21].Name    ...
-----------------------------   ------------------------------- ------------------------------------
null                            null                            null
A                               null                            null
A                               A                               null
...
G                               G                               F
G                               G                               G

似乎没有任何关系。

您能否向我们展示一个表模式、一些示例数据和所需的输出？您可能必须考虑表和列的名称来弥补数据。我想知道您的数据是否以无意义的方式导入 Access？
