In August 2009 I wrote a tip concerning checklists for third-party applications running against Microsoft SQL Server. I thought it was a good time to revisit the topic and provide an added bonus: a requirements document that you can download and customize for your own uses.

It came as a surprise to many of us when Microsoft pulled from it's hat a rabbit in the form of an exciting, radical, language that offers an effective alternative to the Object-oriented orthodoxy. The creative force behind this language, F#, turns out to be a brilliant Cambridge-based Australian called Don Syme, already well known for his work on generics in .NET. F# has taken the specialised power of ML and OCaml and developed a versatile general-purpose .NET language. We sent Richard Morris across the road to investigate.

It is important to ensure that SQL code is laid out the best way for the team that has to use and maintain it. Before you work out how to enforce a standard, one has to work out what that standard should be for the application. So do you dive into detail or create an overall logic to the way it is done?

Fabiano launches into a sound technical explanation of the way that the query optimiser works in SQL Server with a mention of Brazilian Soccer stars and young ladies on Copacabana beach. You'll never quite think of statistics, execution plans, and the query optimiser the same way again after reading this, but we think you'll understand them better.

It would be nice if we could use the DBCC PAGE command to see exactly what it is stored at the page level, however, in order to do this we need to find a way to correlate the results returned from a SELECT statement with the physical data location. Is that possible? The answer is: YES. All we need to do is use the sys.fn_physLocFormatter function. In this tip, I will cover how to use this undocumented function.

'Help, my database ate my disk drives!'. Many DBAs spend most of their time dealing with variations of the problem of database processes consuming too much disk space. This happens because of errors such as incorrect configurations for recovery models, data growth for large objects and queries that overtax TempDB resources. Rodney describes, with some feeling, the errors that can lead to this sort of crisis for the working DBA, and their solution.

I have some data in a table:
CREATE TABLE #test_data

SELECT *
FROM OPENJSON(
(
SELECT t.* FROM #test_data AS t FOR JSON PATH
)
) t; See possible answers
