Is it possible for foxpro in sql statement to fill the winners_name column base on condition maximum score and id with different names - sql

Question

Is it possible for foxpro in sql statement to add and fill a winners_name column base on condition maximum score and id with different names.
I have created a sql statement but it was not supported by foxpro, is there other alternative to do this rather than using a loop (I like sql statement for faster result even in 50k row lines)
SELECT * , ;
(SELECT TOP 1 doc_name FROM Table1 as b1 WHERE ALLTRIM(b1.id) = a.id ORDER BY b1.score DESC, b1.id) as WINNERS_NAME ;
FROM Table1 as a
I have only 1 table, with columns [ name, id, score ]
A sample table would be like this
NAME | ID | SCORE |
BEN | 101 | 5 |
KEN | 101 | 2 |
ZEN | 101 | 3 |
JEN | 103 | 4 |
REN | 103 | 3 |
LEN | 102 | 5 |
PEN | 102 | 4 |
ZEN | 102 | 3 |
The result would be like this (winners_name is tag on ID)
NAME | ID | SCORE | WINNERS_NAME
BEN | 101 | 5 | BEN
KEN | 101 | 2 | BEN
ZEN | 101 | 3 | BEN
JEN | 103 | 4 | PEN
REN | 103 | 3 | PEN
LEN | 102 | 5 | LEN
PEN | 103 | 5 | PEN
ZEN | 102 | 3 | LEN

Answer 1

Try this approach:
SELECT
a.NAME,
a.ID,
a.SCORE,
b.WINNERS_NAME
FROM Table1 a
INNER JOIN
(
SELECT t1.ID, t1.NAME AS WINNERS_NAME
FROM
(
SELECT ID, SCORE, MIN(NAME) AS NAME
FROM Table1
GROUP BY ID, SCORE
) t1
INNER JOIN
(
SELECT ID, MAX(SCORE) AS MAX_SCORE
FROM Table1
GROUP BY ID
) t2
ON t1.ID = t2.ID AND
t1.SCORE = t2.MAX_SCORE
) b
ON a.ID = b.ID
ORDER BY
a.ID;
