Thanks for the question Ron.

After messing-up with LEAD part-1 the other day, this question was easy to solve :-)

Thanks for the question

Will someone please explain example C in english

CREATE TABLE T (a int, b int, c int);
GO
INSERT INTO T VALUES (1, 1, -3), (2, 2, 4), (3, 1, NULL), (4, 3, 1), (5, 2, NULL), (6, 1, 5);

SELECT b, c,
LEAD(2*c, b*(SELECT MIN(b) FROM T), -c/2.0) OVER (ORDER BY a) AS i
FROM T;



I am very confused over the first parameter 2*c

I reviewed John Arnott's fine explanation in the previous question and was able to figure it out from that.

Nice question.

Thanks for the 2012 question! These functions are similar to ones that QlikView has in their query language for referencing the previous or next row in a set. Very handy. Too bad I cannot take advantage of these since none of my production systems are on 2012 yet. Crying

Nice question, and easy.

But I suspect a sales manager who noticed that goals were being set like that would not be happy - fancy giving the salesman who made the best sales last month the target of achieving just last months worst performance this month!
