• Spatial data from shapefiles (for T-SQL Tuesday #006)

  - by Rob Farley

  I’m giving a presentation on May 12th at the Adelaide .Net User Group, around the topic of spatial data, and in particular, the visualization of said data. Given that it’s about one the larger types, this post should also count towards Michael Coles’ T-SQL Tuesday on BLOB data . I wrote recently about my experience with exploded data , but what I didn’t go on to talk about was how using a shapefile like this would translate into a scenario with a much larger number of shapes, such as all the postcode...(read more)

• getting bone base and tip positions from a transform matrix?

  - by ddos

  I need this for a Blender3d script, but you don't really need to know Blender to answer this. I need to get bone head and tip positions from a transform matrix read from a file. The position of base is the location part of the matrix, length of the bone (distance from base to tip) is the scale, position of the tip is calculated from the scale (distance from bone base) and rotation part of the matrix. So how to calculate these? bone.base([x,y,z]) # x,y,z - floats bone.tip([x,y,z])

• Difference between DISTINCT and VALUES in DAX

  - by Marco Russo (SQLBI)

  I recently got a question about differences between DISTINCT and VALUES in DAX and thanks to Jeffrey Wang I created a simple example to describe the difference. Consider the two tables below: Fact and Dim tables, having a single column with the same name of the table. A relationship exists between Fact[Fact] and Dim[Dim]. This relationship generates a referential integrity violations in table Fact for rows containing C, which doesn’t exist in table Dim. In this case, an empty row is virtually inserted...(read more)

• Byobu not displaying correct CPU temptrature

  - by aserwin

  I have an AMD FX 8120 proccy that is overclocked to 4100Mhz. Since the overclocking, Byobu and other temprature reading apps (Conky, etc) do not read the temprature accurately. I can see the correct temp in the bios, and with no overclocking everything inside of Gnome reads correctly. Why should this be? It is (seemingly) obviously an issue with Ubuntu (or perhaps Gnome?). Has anyone else experienced this?

• Using another browser than w3m for reading HTML helpfiles?

  - by NES

  I'm using fish as shell. The internal help is based on html files and when i type help, it opens w3m to view this help files. Since w3m is not my default browser i wonder where this configuration to start w3m for this is stored. I'd like to read the helpfiles with another browser. How can i setup another one for this purpose or perhaps where are the helpfiles located so i can open them manually in the browser.

• Why is Internet Explorer the only browser to be referred to by version when talking about compatibility?

  - by Rue Leonheart

  Whenever I read something or hear someone talking about HTML5, CSS and JavaScript support, they always refer to Internet Explorer with the version number such as Internet Explorer 6, and Internet Explorer 9. But they only refer to Google Chrome, Firefox, Safari and others without version numbers. Shouldn't they also specify the version number in which certain web technologies are incompatible for other browsers instead of just Internet Explorer?

• How many per-core licenses do I need?

  - by GavinPayneUK

    With SQL Server 2012, your licensing requirements can chose to use or be required to use a per-core model depending on the edition you’re deploying. This is a change to previous editions which used a per-CPU socket model that made counting how many per-CPU licences you needed easier – cores and HyperThreading didn’t influence the CPU socket count.  Any complications which people did have typically came from running SQL Server in a virtualised environment, was a vCPU a socket or did licensing...(read more)

  In a previous post about changed system objects in Denali , I talked about the changes to memory-related DMVs due to underlying changes in the memory manager.

• Yet another use of OUTER APPLY in defensive programming

  - by Alexander Kuznetsov

  When a SELECT is used to populate variables from a subquery, it fails to change them if the subquery returns nothing - and that can lead to subtle bugs. We shall use OUTER APPLY to eliminate this problem. Prerequisites All we need is the following mock function that imitates a subquery: CREATE FUNCTION dbo.BoxById ( @BoxId INT ) RETURNS TABLE AS RETURN ( SELECT CAST ( 1 AS INT ) AS [Length] , CAST ( 2 AS INT ) AS [Width] , CAST ( 3 AS INT ) AS [Height] WHERE @BoxId = 1 ) ; Let us assume that this...(read more)

• Database Maintenance Scripting Done Right

  - by KKline

  I first wrote about useful database maintenance scripts on my SQLBlog account way back in 2008. Hmmm - now that I think about it, I first wrote about my own useful database maintenance scripts in a journal called SQL Server Professional back in the mid-1990's on SQL Server v6.5 or some such. But I digress... Anyway, I pointed out a couple useful sites where you could get some good scripts that would take care of preventative maintenance on your SQL Server, such as index defragmentation, updating...(read more)

• Using jQuery to customize the styles in table cells

  - by Chris Hammond

  Originally posted on ChrisHammond.com I was trying to do some work with the Form and List module in DotNetNuke today and I needed to apply some custom styles to the LIST view of a module, without going in and creating a full XSL template for the module to use, I wanted to style the default table based grid view. In order to customize this view though I needed to do some custom jQuery that runs after the table is loaded, the jQuery then goes through and looks for columns, and based on the number of...(read more)

• Rounding functions in DAX

  - by Marco Russo (SQLBI)

  Today I prepared a table of the many rounding functions available in DAX (yes, it’s part of the book we’re writing), so that I have a complete schema of the better function to use, depending on the round operation I need to do. Here is the list of functions used and then the results shown for a relevant set of values. FLOOR = FLOOR( Tests[Value], 0.01 ) TRUNC = TRUNC( Tests[Value], 2 ) ROUNDDOWN = ROUNDDOWN( Tests[Value], 2 ) MROUND = MROUND( Tests[Value], 0.01 ) ROUND = ROUND( Tests[Value], 2 )...(read more)

• Finding a Payment Gateway?

  I have a client who would like to sell glass pipes online. The problem I run into is with the payment gateway. Glass pipes fall into two categories drug paraphernalia or tobacco product. This leads me to here and asking: Does anyone know of a payment gateway that will process payments for glass pipes?

• Slides and demo code for Columnstore Index session

  - by Hugo Kornelis

  Almost a week has passed after SQLBits X in London , so I guess it’s about time for me to share the slides and demo code of my session on columnstore indexes. After all, I promised people I would do that – especially when I found out that I had enough demos prepared to fill two sessions! I made some changes to the demo code. I added extra comments, not only to the demos I could not explain and run during the session, but also to the rest, so that people who missed the session will also be able to...(read more)

The product is still being developed and your early feedback can make a difference. When you click Download Registration Certificate...(read more)

• PowerPivot FILTER condition optimizations

  - by Marco Russo (SQLBI)

  In the comments of a recent post from Alberto Ferrari there was an interesting note about different performance related to the order of conditions in a FILTER call. I investigated about that and Jeffrey Wang has been so nice to give me some info about actual implementation that I can share on a blog post. First of all, an important disclaimer: PowerPivot is intended to make life easier, not requiring the user to think how to write the order of elements in a formula just to get better performance....(read more)
