Excuse me for posting a similar question. Please consider this:
date value
18/5/2010, 1 pm 40
18/5/2010, 2 pm 20
18/5/2010, 3 pm 60
18/5/2010, 4 pm 30
18/5/2010, 5 pm 60
18/5/2010, 6 pm 25
19/5/2010, 6 pm 300
19/5/2010, 6 pm 450
19/5/2010, 6 pm 375
20/5/2010, 6 pm 250
20/5/2010, 6 pm 310
The query is to get the date and value for each day such that the value obtained for that day is max. If the max value is repeated on that day, the lowest time stamp is selected. The result should be like:
18/5/2010, 3 pm 60
19/5/2010, 6 pm 450
20/5/2010, 6 pm 310
The query should take in a date range like the one given below and find results for that range in the above fashion:
where date >= to_date('26/03/2010','DD/MM/YYYY') AND date < to_date('27/03/2010','DD/MM/YYYY')
