First column holds the givin datetime from my table and the second column should show the datetime from first row but 12 hours before. for example: '2011-12-31 09:00' '2011-12-30 21:00' '2011-12-31 12:15' '2011-12-30 00:15' ... looks simple but datetime was not sufficient for this in my research. Very thanks for your help.
