Question

Given the database…..

ID     Name     item_order     Manager
1      ted      2                N
2      bob      5                N
3      tony     1                Y
4      fred     3                N
5      william  4                N 
6      george   6                Y
7      cade     8                N
8      matt     7                N

I would like to be able to select managers Id prior to the current non managers name. So for example the result for bob would be tony or 3.

I can figure out how to do this with two requests

SELECT MAX( item_order) AS parent
FROM tablename WHERE item_order < 5 && Manager =  'Y'

The result from that I would make another select by the item_order. Is there a way to do this all in one select?

Answer 1

SELECT * FROM tablename
WHERE Manager = 'Y'
AND item_order = (SELECT MAX(item_order) AS parent
                  FROM tablename 
                  WHERE item_order < 5 
                  AND Manager =  'Y') AS t
