Ms Access Query:通过查询连接行

问题描述

假设我在 Ms Access 中有包含以下信息的表:

Suppose I have table in Ms Access with following information:

ColumnA ColumnB
1       abc
1       pqr
1       xyz
2       efg
2       hij
3       asd

我的问题是，如何将第二列中的值连接到基于第一列的行值.我想要的查询结果如下:

My question is, how can I concatenate the values in the second column to a row value based on the first column. The query results that I want is as follows:

ColumnA ColumnB
1       abc, pqr, xyz
2       efg, hij
3       asd

我想通过查询来实现这一点.有人能帮我实现这个吗?

I want to achieve this through a query. Can someone help me attain this?

推荐答案

您需要一个函数来进行串联.

You need a function to do the concatenation.

Microsoft Access 在表格中压缩多行

使用您的数据的示例:

Select T.ColumnA
  , GetList("Select ColumnB From Table1 As T1 Where T1.ColumnA = " & [T].[ColumnA],"",", ") AS ColumnBItems
From Table1 AS T
Group By T.ColumnA;
