RE: Need help with SQL query

["Chris Payne" <CPayne@xxxxxxxxxxxxxxx>]

Lets say you have 

John     Smith    25         60000

John     Smith    40         20000

John     Smith    20         15000

As the only contents of your file, which record do you want back? If we
get the John Smith with the highest salary, or the John Smith with the
highest age we will be down to one John Smith and it will be meaningless
to narrow it down further.

Subject: Need help with SQL query

I am trying to figure out a query that needs to display rows of grouped
data
based on max values of two columns.

 

Here is an example.

 

Fname  lname   age       salary

----------  ---------   ----        --------

John     Smith    39         20000

John     Smith    38         20000

John     Smith    40         15000

Adam    Apple    20         25000

Adam    Apple    21         25000

Adam    Apple    19         18000

 

I need to return one line from each group (one john smith and one Adam
Apple) based on highest salary and age.  For john Smith, highest Salary
is
20000 and then highest age is 39, so the row returned would be John
Smith 39
20000.  For Adam Apple it would be Adam Apple 21 25000.

 

I can get it narrowed down to rows grouped with highest salary, but then
I
can not think how to get it to narrow it down another level and only
display
the one with the larger age number after that.
