select id, pid, name (SELECT max(saved) WHERE pid = 2.pid) AS max_date, (SELECT min(saved) WHERE pid = 2.pid) as min_date
from property property1
where saved = (select max(saved) from property where pid = property1.pid)
ORDER BY max_date;
Does this sound better...?
Bear in mind this is from an oracle guru...
Anyway, will check this out when I get home and have a db to play around with.

I am sure I could do that, but really wanted to package it neatly into a query.
Programming is being done in PERL

dbix::searchbuilder::handle::mysql
DBIx::SearchBuilder::Handle::mysql(3pm) User Contributed Perl Documentation DBIx::SearchBuilder::Handle::mysql(3pm)NAME
DBIx::SearchBuilder::Handle::mysql - A mysql specific Handle object
SYNOPSIS DESCRIPTION
This module provides a subclass of DBIx::SearchBuilder::Handle that compensates for some of the idiosyncrasies of MySQL.
METHODS
Insert
Takes a table name as the first argument and assumes that the rest of the arguments are an array of key-value pairs to be inserted.
If the insert succeeds, returns the id of the insert, otherwise, returns a Class::ReturnValue object with the error reported.
SimpleUpdateFromSelect
Customization of "SimpleUpdateFromSelect" in DBIx::SearchBuilder::Handle. Mysql doesn't support update with subqueries when those fetch
data from the table that is updated.
DatabaseVersion
Returns the mysql version, trimming off any -foo identifier
CaseSensitive
Returns undef, since mysql's searches are not case sensitive by default
SimpleDateTimeFunctions
Returns hash reference with specific date time functions of this database for "DateTimeFunction" in DBIx::SearchBuilder::Handle.
ConvertTimezoneFunction
Custom implementation of "ConvertTimezoneFunction" in DBIx::SearchBuilder::Handle.
Use the following query to get list of timezones:
SELECT Name FROM mysql.time_zone_name;
Read docs about keeping timezone data up to date:
