Hi All,

In case of using GROUP BY in SQL-SELECT, The Last record of criteria
is selected for each group though there is no aggregate field.
But I heard it's unreliable. Here is my code.

** because records are not inserted in the order of date,
** select all records from table sorted by desired order
** before real SQL.
** Though mytable has INDEX for custid+dtos(date) and I open
** with proper order with another alias, SQL only tells phisically
** saved last record.

lcAlias=SYS(2015)
select custid,date,debt,custid+dtos(date);
FROM myTable ;
where date < someday;
into cursor (lcAlias) order by 4

** get the last debt of each custid
select custid,MAX(date),debt from (lcAlias);
GROUP BY CUSTID into cursor myCursor
** select custid,date,debt from (lcAlias);
** GROUP BY CUSTID into cursor myCursor

Though I can have the last debt and date per custid correctly,
I'm not so sure My way is correct.
And in ther 2nd-Query, Regardless of using MAX() I have the
same result. I need an advice what is the most reliable way
to get the last record of some specific order.

Any comments would be appreciated.
