I have a table that has a series of dates along with an ID:
A 3/6/1987 12:00:00 AM
A 4/1/1988 12:00:00 AM
A 4/28/1989 12:00:00 AM
B 3/6/1987 12:00:00 AM
B 4/1/1988 12:00:00 AM
I would like to find the maximum A that is before say 04/27/1988.
This does not work, and I cant figure out why:
Select max(My_date) from Mytable
where MY_ID = 'A'
and My_date < str_to_date('04/27/1988')
group by MY_ID
it always just gives me the max() record
