BOF() is an XBase iterative function, nothing to do witrh SQL ensembly

conceipt.

Somewhere, excluding it.

However; it is always possible to replace this lack of logic.

If we consider the previous example :

[VFP]

CREATE CURSOR test ;

(lib c(10),mt i)

INSERT INTO test VALUES ("john",10)

INSERT INTO test VALUES ("jennifer",15)

INSERT INTO test VALUES ("stella",25)

INSERT INTO test VALUES ("sophia",40)

INSERT INTO test VALUES ("greg",50)

INSERT INTO test VALUES ("jeff",20)

[/VFP]

It is possible to "create a rank" according to a choosen order.

Let's do it. We choose to order "mt" values :

[VFP]

SELECT xx.lib, xx.mt, COUNT(yy.mt) as rank ;

FROM test xx, test yy ;

WHERE xx.mt <= yy.mt ;

GROUP BY xx.lib, xx.mt ;

ORDER BY xx.mt DESC, xx.lib DESC

[/VFP]

Once upon this order is made, we can determine

a numeric distance delta (your question) from

BOF() or EOF().

The final request beeing trivial,

i would't offense your professional side

by giving you tricks on me.

Gérard.
