  • Ranking with PowerPivot – a different approach

    - by Marco Russo (SQLBI)
    Alberto Ferrari wrote an interesting post about a “different approach” in creating a ranking measure with PowerPivot . If you know DAX or you read our book , you will find that a DAX expression can solve the issue. However, such a formula is more complex than necessary. The next version of PowerPivot might have more built-in DAX functions and should solve the ranking need with a simpler formula. In the meantime, it is interesting to know a different approach that relies on Excel skills instead of...(read more)

  • Highlighting repeating groups in SSRS 2008 R2 charts

    In a typical bar chart, the height of the bars represents the value of the data along the X axis and the Y axis represents the category of the data point. All these values can be classified in logical groups depending upon the logic used for analysis. One general requirement that arises in the case of repeating groups, is to highlight these groups without representing it on the X or Y scale. In this tip we will look at how to address this requirement.

  • Rules of Holes #7: Some Will Look Down on You.

    - by ArnieRowland
    I've been extoling the Rules of Holes, hoping to give you both courage to get out of your Hole, and solace for having allowed yourself to get in a Hole in the first place.

So this brings us to Rules of Holes #7: When you are in a hole, some will look down on you. Only a few will offer their hand, and of those,...(read more)

  • A marketing view of SQLBits

    - by simonsabin
    One of the most enjoyable things about SQLBits is reading all the blog posts/reviews after the event. We are normally fortunate enough not to have pissed anyone off and so the posts are generally positive. Most pieces are from attendees however this piece is from a wife of a sponsor http://iknowmarketing.wordpress.com/2012/04/02/events-community-vs-commercial/ . Its a nice piece for us as it highlights how we work and that how we focus on making the event personal for all those involved. We deal...(read more)

  • Visual Studio 2010: Is it possible to force editor to use ANSI rather than UTF-8?

    - by Mark Redman
    I am having issues with some files in automated processes, specifically with batch files and sql files. Visual Studio seems to create these as UTF-8 rather than ansi and adds some kind of special characters to the beginning of the file (I think this is a called a pre-amble) This breaks running batch files and running swl files through osql.exe. I have had issues myself in the past in creating text files using C#, but can get around that through encoding. However its seems a bit strange I cant use Visual studio to create batch files and sql files in a database project for automation.

  • Search For a Query in RDL Files with PowerShell

    - by AllenMWhite
    In tracking down poorly performing queries for clients I often encounter the query text in a trace file I've captured, but don't know the source of the query. I've found that many of the poorest performing queries are those written into the reports the business users need to make their decisions. If I can't figure out where they came from, usually years after the queries were written, I can't fix them. First thing I did was find a great utility called RSScripter , which opens up a Windows dialog...(read more)

  • What's better for deploying a website + DB on EC2: 2 small VM or a large one?

    - by devguy
    I'm planning the deployment of a mid-sized website with a SQL Server Standard DB. I've chosen Amazon EC2 to deploy it. I now have to choose between these 2 options: 1) get 2 small instances (1 core each, 1.7 GB of ram each): one for the IIS front-end, one for running the DB. Note: these "small instances" can only run the 32-bit version of Win2008 Server 2) a single large instance (4 cores, 7.5 gb of ram) where I'd install both IIS and the SQL Server. Note: this large instance can only run the 64-bit version of Win2008 Server What's better in terms on performance, scalability, ease of management (launch up a new instance while I backup the principal instance) etc. All suggestions and points of view are welcome!

    During weekend maintenance, members of the support team executed an UPDATE statement against the database on the OLTP Server.

  • Rules of Holes #1: Stop Digging

    - by ArnieRowland
    You may have heard of the 'First Rule of Holes'. It goes something like this: " When you suspect you might be in a hole, stop digging. " That seems like obvious, and good advice, but what does it really mean? How does the Rule of Holes apply to you? How does it apply to your job? When things are not going right, stop doing the "same ol', same ol'" You find yourself involved in doing the same type of coding over and over. Maybe it's time to stop, step back, take a little time and learn something new....(read more)

    If you’ve had your ear to the twitter ground you will have seen that the provisional agenda for SQLBIts has been put online. http:// sqlbits .com/information/agenda.aspx You will also notice that we have put on a little weight.

  • How selective do we need to be for an index to be used?

    - by TiborKaraszi
    You know the answer already: It depends. But I often see some percentage value quoted and the point of this post is to show that there is no such percentage value. To get the most out of this blog post, you should understand the basic structure for an index, i.e. how the b+ tree look like. You should also understand the difference between a clustered and a non-clustered index. In essence, you should be able to visualize these structures and searches through them as you read the text. If you find...(read more)

  • SSDs at PASS 2012

    - by jchang
    There were 7 companies exhibiting SSD products as PASS this year, and one with a product to support SSD storage. This is not counting Dell, EMC and HP who have SSD products, but were at PASS for other reasons. This shows that many have aspirations with the hope that market leadership is not yet firmly set. The products fall into the following: PCI-E SSDs (Fusion-io, LSI, Virident) SSD SAN (Violin, TMS, Whiptail) SSD caching (LSI, GridIron) I am inclined to be of the opinion that SSD market is not...(read more)

  • Summarising and Bubbling of KPI data

    - by simonsabin
    Something I’m very conscious of when delivering a  BI solution is being able to show the facts in a concise way but also not to hide whats going on. I was reminded of this when I looked at the weather today. Everywhere they are reporting weather warnings for the south east and so I though I’d check on the BBC website http://news.bbc.co.uk/weather/forecast/4281?area=AL5 Looking at that I thought we are going to miss the worst of it, just like a few weeks ago. However from previous experience...(read more)

  • MS Access 2007 end user access

    - by LtDan
    I need some good advise. I have used Access for many years and I use Sharepoint but never the two combined. My newly created Access db needs to be shared with many users across the organization. The back end is SQL and the old way to distribute the database would be placing the db on a shared drive, connecting their PC ODBC connections to the SQL db and then they would open the database and have at it. This has become the OLD way. What is the best (and simpliest) way to allow the end users to utilize a frontend for data entry/edit reporting etc. Can I create a link through SharePoint and the user just open it from there. Your good advise is greatly approciated.
