One of my developers ... part of a very long piece of SQL near the end ... lots of inline views ... and this creative piece of code:

(

SELECT POC.PO_ID, POC.LINE_ITEM_PO, POC.COMMENT_PO, POC.DATE_ADD_COMMENT
FROM PO_COMMENT POC
WHERE (POC.PO_ID,POC.LINE_ITEM_PO,POC.ROW_TIMESTAMP) IN
(SELECT A.PO_ID,A.LINE_ITEM_PO,MAX(A.ROW_TIMESTAMP)
FROM PO_COMMENT A
WHERE A.TYPE_PO_COMMENT='LE' GROUP BY A.PO_ID, A.LINE_ITEM_PO) ) T193

Plus of course ... PO_COMMENT is a very big table ... Received on Fri Dec 14 2012 - 01:55:26 CET
