Transpose poorly designed table in Access 2000 query

[Flopper]

Greetings,

I'm attempting to transpose a poorly designed table into a query but without much luck.

The table contains an ID field and 20 additional fields containing dates (Dt1 to Dt20).
ID[tab][tab][tab]Dt1[tab][tab][tab]Dt2[tab][tab][tab]Dt3[tab][tab][tab]Dt4[tab]

I need to tranpose the table to show a row for each Dt field. i.e.
Id[tab]Dt1
Id[tab]Dt2
Id[tab]Dt3
Id[tab]Dt4

How can this be achieved? I know it can be done by multiple single line queries and union statements but this seems inefficient.

Any help truly appreciated.

Thanks

inefficient or not, i think that's the only way

Try a union query like:

SELECT ID, Dt1 as TheDate, 1 as DateNum
FROM tblPoorlyDesigned
UNION ALL
SELECT ID, Dt2, 2
FROM tblPoorlyDesigned
UNION ALL
SELECT ID, Dt3, 3
FROM tblPoorlyDesigned
UNION ALL
SELECT ID, Dt4, 4
FROM tblPoorlyDesigned
UNION ALL
---etc---
SELECT ID, Dt20, 20
FROM tblPoorlyDesigned;
