The Wisdom Department

Steve Jones talks about the way business ought to run, with more long term goals and objectives taking precedence over short term revenue. One idea that might help us is having a wisdom department that looks forward and tries to grow the business for the long term.

Question of the Day

Estimated Rows

I have two calls to the GENERATE_SERIES TVF in this code:

SELECT   TOP 10 gs.value
FROM     GENERATE_SERIES(1, 10) AS gs
ORDER BY NEWID ()
OPTION (RECOMPILE);
go
DECLARE @a int = 10;
SELECT   TOP (@a) gs.value
FROM     GENERATE_SERIES(1, @a) AS gs
ORDER BY NEWID ()
OPTION (RECOMPILE);
In the actual query plans, what is the estimated number of rows for each batch?
