Question

Lets say I have data in two tables. In one I have Order ID and Order Date. In the other I have Order ID, Description and Value. I know how to do simple SELECTs but what would I use to output something like this?

Order ID | Order Date | Description                     | Value
1234     | 10/07/2009 |                                 |
         |            | Orderline description goes here | 53.49
         |            | Orderline description goes here | 25.63
         |            | Orderline description goes here | 21.64
12345    | 11/07/2009 |                                 |
         |            | Orderline description goes here | 12.37
         |            | Orderline description goes here | 13.86
         |            | Orderline description goes here | 17.79

Supposing you maintain a foreign key constraint between TABLE1 and TABLE2 on ORDER_ID field….

SELECT t1.ORDER_ID as [ORDER ID],
       t1.ORDER_DATE as [ORDER DATE],
       t2.DESCRIPTION,
       t2.VALUE
FROM 
       TABLE1 t1 INNER JOIN TABLE2 t2 ON
              t1.ORDER_ID = t2.ORDER_ID

Then on the GUI ignore the repeating values…

OR you can take UNIONS…

SELECT ORDER_ID as [ORDER ID],
       ORDER_DATE as [ORDER DATE],
       NULL as DESCRIPTION,
       NULL as VALUE
FROM TABLE1
     ORDER BY ORDER_ID

UNION ALL

SELECT NULL as [ORDER ID],
       NULL as [ORDER DATE],
       DESCRIPTION,
       VALUE
FROM TABLE2
     ORDER BY ORDER_ID

but you still have to do few thing on the GUI.
