So you have a Table, let's say joined Sales Order Detail with Part, and Inventories and you need to get the most recent SO for each part number. How would you write the query?

Here is a simplified schema:

CREATE TABLE [dbo].[Part]
(
   [part_no] VARCHAR(5)
  ,[rev] CHAR
  ,[on_hand] TINYINT
  ,[safety_stock] TINYINT
  ,[so_no] VARCHAR(5)
  ,[so_date] DATETIME
)




INSERT [dbo].[Part]
SELECT '12345', 'A', 10, 15, 'S1234', '12/14/2009' UNION ALL
SELECT '12345', 'A', 10, 15, 'S1233', '10/01/2009' UNION ALL
SELECT '12345', 'A', 10, 15, 'S1232', '08/02/2009' UNION ALL
SELECT '12346', '',  5, 0, 'S1231', '08/01/2009' UNION ALL
SELECT '12347', '-', 0, 0, 'S1230', '10/20/2009' UNION ALL
SELECT '12347', '-', 0, 0, 'S1229', '07/15/2009'
