Suppose I have a table T that has, among its columns, the fields X and Y,
where Y is an integer, and multiple rows with the same value of X are
possible. I want to select the rows corresponding to the greatest values of
Y for each value of X. E.g. suppose that T is
X Y Z
a 1 eenie
a 3 meenie
a 2 miny
b 4 moe
b 0 catch
...the result of the desired query would be
a 3 meenie
b 4 moe
TIA!
