The Bit Bucket

When you first make a connection to the new LocalDB edition of SQL Server Express, the system files, etc. that are required for a new version are spun up. (The system files such as the master database files, etc. end up in

C:\\Users\\<username>\\AppData\\Local\\Microsoft\\Microsoft SQL Server Local DB\\Instances\\LocalDBApp1) 

That can take a while on a slower machine, so this means that the default connection timeout of 30 seconds (in most client libraries) could be exceeded.

One of the things that I have been pestering the SQL team to do is to name their updates according to what is contained in them. For example, instead of just:

sqlncli.msi 

What I’d prefer is that the file was called something like:

SQLServerNativeClient2k8SP1CU3x64.msi

So I normally rename them as soon as I receive them, to avoid confusion in future. However, today I found that doing so caused me a problem. After renaming the file, and installing it, the installation failed with the error:

It’s great to see that volume 2 of MVP Deep Dives is now available and will be distributed at the PASS summit next week. I’m really sad that I won’t be at the book signing next week but I’d encourage you all to get along, order a copy and have it signed.

A huge thanks has to go to Kalen Delaney for her management of this project and a big thanks to my fellow editors Louis Davidson, Brad McGehee, Paul Nielsen, Paul Randal, and Kimberly Tripp for their efforts. A special mention for Paul Nielsen whose ideas and spirit around volume 1 that have continued into this new volume.

Part of the value in the ongoing evolution of the T-SQL language is that we are moving further and further towards being declarative rather than prescriptive ie: we are able to tell SQL Server what we want, rather than how to do it. Over time, that raises more and more possibilities for the optimizer to work with us to achieve a better outcome.

For example, note the following query against the AdventureWorksDW database:

With SQL Server, there often seems to be an over-emphasis on the items that provide bullet points for the marketing brochure. Yet, small but useful changes to the product can make a more profound impact on DBAs/developers than the new items that are highlighted by those bullet points.

One of the things I loved about Reporting Services in SQL Server 2008 R2 is the amount of focus they provided on ease of use. In particular, the addition of data bars, lookup functions, pagination control, rendering targets in expressions, domain scope, etc. made a huge difference to anyone that really needs to build reports.

We end up staying in Sydney several times per year, either for training or mentoring/consulting work. When we do, one of the hotels that we really like is the Westin. I would find it hard though, to list all the reasons why I like it. (There are some things I don’t like about it too but that’s a topic for another day).

But one of the things that has always surprised me, each and every time I eat breakfast there, is how sharp the knives are. Clearly, someone must be assigned to sharpen them, or they replace them very regularly (unlikely). Alternately, one of the staff members might have been passionate about it and it was an individual thing but we stayed about 160 nights in hotels last year and I can tell you that most hotels (big or small) don’t bother doing this.

I really liked the addition of the WITH EXECUTE AS clause when defining stored procedures and functions, to change the execution context, just for the duration of the stored procedure or function. For example:

CREATE PROC SomeSchema.SomeProc

WITH EXECUTE AS USER = ‘Fred’

AS

… 

I’d also used the EXEC AS clause to temporarily change my execution context during testing. For example:

EXEC AS USER = ‘Fred’;

-- Try some code here while running as Fred

One thing I love about T-SQL is that every day I seem to find another way to use it that wasn’t immediately obvious to me. I was reading the SQL Server Denali documentation and noticed that in the definition of the EXEC command that it said you could execute a stored procedure or scalar function using EXEC.

While I’d obviously used it to call a stored procedure, it had never dawned on me that you could use EXEC to call a scalar UDF, so I had to try it. Sure enough, it’s obviously worked for a long time. Here’s an example of a function and calling it as I would have in the past:

I’ve been doing some work with PowerPivot and SharePoint/Excel Services this week. I wanted the user interface to have slicers for:

• Year
• Month
• Day

But I wanted the slicer to be preselected for the current month. There is no property on the slicers to set a default value. I read a number of websites and the suggestion was to use VBA code to set the value. This works but if you want to have the VBA code run at workbook open, you have to create a macro-enabled workbook, and these are not supported by Excel Services.

Ola has updated his index optimization scripts again. The update relates to logging to a table.
