i'm not sure how to explain so I'll try and write out an example.

I'm currently using an access database with a table in the following format

  • 1 A B C D
  • 2 A B C D

I'm trying to perform a query that will provide me with an output in the following format:

  • 1 A
  • 1 B
  • 1 C
  • 1 D
  • 2 A
  • 2 B
  • ....

Currently this will be performed on a Access Db but later on it will need to be converted to a SQL Server query.

I'm not that fluent in SQL so any help would be welcome :)

Thanks!

This will work wit Access and SQL-Server

SELECT ID, A AS Fieldx
FROM tbl 
UNION ALL
SELECT ID, B
FROM tbl 
UNION ALL
SELECT ID, C
FROM tbl
UNION ALL
SELECT ID, D
FROM tbl;

specific for SQL-Server:

SELECT ID, FieldX FROM 
   (SELECT ID,A,B,C,D   FROM tbl) p
UNPIVOT
   (FieldX for dummyID in (A,B,C,D)) as dummyField

  • Thanks for the info! Looking from the examples this looks very promising :) My only concern is with the "generic" query because this would become a really big one depending on the amount of columns. I have read something about a "Transform" function which would be similar to Pivot, do you happen to have knowledge of this for Access? – Dirk R. Dec 25 '12 at 19:59
  • You can find examples here ewbi.blogs.com/develops/2005/01/access_sql_tran.html msdn.microsoft.com/en-us/library/office/… but if I got you right you are searching for the opposite. – bummi Dec 25 '12 at 20:26
  • That indeed seems to be the opposite of what I'm trying to do. ( Same for Crosstab ) I should be able to do what I need to do with the union all and hope that they move the data to a SQL DB soon :) – Dirk R. Dec 25 '12 at 22:06
