We just reticently received a update to an .net application from a vendor. When our client machines (Windows XP) run the app we receive 2 different date formats returned from an post insert table trigger. The correct format is 'DD-MON-YY' in which a couple machines still return and the others return the format 'YYYY-MM-DD HH24:MM:SS'. I've tried setting the NLS_Date Format with no success. Any suggestions?
