Question

Suppose I have table in Ms Access with following information:

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

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

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

Answer 1

You need a function to do the concatenation.

Microsoft Access condense multiple lines in a table

Example using your data:

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;
