Planning for tomorrow, today - database migrations

  • Editorial

I have been speaking to people about database migrations to the cloud a lot over the last few weeks. One thing that has jumped out at me is that we seem to focus on the process of moving data being the migration rather than one step in a larger process. Many people neglect the discovery […]

Greener Grass

  • Editorial

Before I start the whining (whinging if you prefer), let me just say I have the greatest job in the world. I'm exceedingly lucky to have it. I'm grateful as can be. And someone else (looking at you Tim) can get it when they pry it from my dead cold fingers. With that out of […]

Feeling your age? How would you know?

  • Editorial

As this idea is being born, I am sitting in a dueling piano bar and I have never felt so old ever. And I don’t mean physically. I have only recognized about 1/4 of the songs being played, and everyone just seems younger than me. Even the people I think are older seem younger as […]

New Year’s Day is probably the most positive day of the year when people, in all manner of situations, think back to the previous rotation around the earth and decide what they will do better this […]

The Pervasive Nature of Open Source

  • Editorial

This week there was a headline that said "Open Source Software Powers 96% of Modern Applications, New Study Finds" and if you stopped reading there, you might think, hey, it's not in the apps I work on. Or you might think that because you use OSS software, most of the world also does. Microsoft, Oracle, […]

Lies You Should Believe - Anything is possible

  • Editorial

We have all heard the saying I based this week's editorial on. It has been credited to Benjamin Franklin and goes like this, “You can do anything you set your mind to”. This is such a powerful way of thinking when you are starting a task. “I can do it, no matter what anyone says.” […]

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 in SQL Server 2022?
