Hi, I need a little help understanding how to attack this problem. I need to find the max(date) of a field but I need that value later in my query.
If I select max(x.date_field) as special_date from (select date_field) from table where ...)x I get one row and column. But now I want to use that field in the rest of the query select y.*, max(x.date_field) as special_date from (select date_field) from table where ...)x from aTable y where y.somefield = special_date. The above only returns one row and one column the "special_date." How can I use the aggregate field "special_date" in the rest of the query? Or is there some other way?
