Hi: Using foxpro, I have a table as follows:

ID Name
------ --------------------
1234 Fred
5678 Robin
2345 Bertha
2345 Bertha Smith
5678 Robin Jackson

I am trying to figure out an SQL query that will identify the people with the longest names, and as a side answer: the number of rows that contain
the same ID. Thank you, Steve

This gets me into the ballpark and I suspect that foxpro can do this:

SELECT r1.id, r1.name, LEN(ALLTRIM(r1.name)) as l, COUNT(r1.id) ;
FROM aan as r1 LEFT JOIN aan as r2 on r1.id = r2.id .and.;
LEN(ALLTRIM(r2.name)) < LEN(ALLTRIM(r1.name)) .or.;
LEN(ALLTRIM(r1.name)) > LEN(ALLTRIM(r2.name));
GROUP BY r1.name, r1.id

But I can't figure out what count(ID) is doing, how to return the number of rows per ID, or how to limit my results
to the rows that have the longest names?
