I have a table of orders with multiple date columns (Department finished dates). I’d like to query the table and return a unique line for each match of a specified date and give a reference to why that line was selected.

So from this table:

OrderID   OrderName   Date1      Date2      Date3
456       feh         5/1/2011   6/1/2011   3/1/2011
487       meh         12/1/2010  2/1/2011   8/1/2011

If queried for any date greater than 4/1/2011 I would like to return:

456       feh         5/1/2011     Date1
456       feh         6/1/2011     Date2
487       meh         8/1/2011     Date3

The data is in MS Access and I’m not sure if this is possible at the query level or would require subreports to produce.

Thanks much for the help!

    Try this to get your last column:

    Select OrderID, OrderName, Date1 as SelDate, 'Date1' as Reason
  from table where date1>'4/21/2011'
UNION ALL  
Select OrderID, OrderName, Date2 as SelDate, 'Date2' as Reason
  from table where Date2>'4/21/2011'
UNION ALL  
Select OrderID, OrderName, Date3 as SelDate, 'Date3' as Reason
  from table where Date3>'4/21/2011'

    Also note that I changed the alias of the SelDate column–even though it’s not critical (in Access) when it’s an alias, you really should avoid naming columns with Reserved Words.
