i have a database that has got tables with images and some of the tiles for the images is repeated and i want to eliminate the duplicates based on which imagery is oldest so as to remain with the newest images, i have run the following to get the duplicates from the database but do not know how to delete the row based on the age of the imagery
select "index",path from ngi_catalog_aug2012 where "index" in (SELECT "index" FROM ngi_catalog_aug2012 GROUP BY "index" HAVING ( COUNT("index") > 1 ) ) order by "index"
this gives results like
index path 2228BD_23 /data/ngi_old/images_30k_sid/2228/2228BD_23_498_469_12_0007_PAN_RECT.sid 2228BD_23 /data/ngi_old/images_30k_sid/2228BD/2228BD_23_498_469_11_0100_PAN_RECT.sid
and i would like to delete for instance the second row
