SQL Server

  • Using Hyper-V and PowerShell to Create the Perfect Developer Workstation

    So the second challenge I faced after unboxing and plugging in my new workstation at Purple Frog Systems was software. Having customers using all versions of SQL Server from 2005 onwards I didn’t want to tie myself to a particular version locally and I also didn’t want the hassle of running lots of different SQL Server services all on the same host operating system. Especially if I wanted to use Windows 10 as my host, which as we…

  • My Introduction to the SQL Server Community

    Once I was blind, but now I see! In the early part of 2015 (I think) a work colleague and friend suggested that on Thursday evening I attend the SQL Server Midlands User Group. The event was completely new to me, I’d never before ventured outside my professional comfort zone, or even had any appreciation that there was such a gathering about SQL Server locally. Anyway, I registered and got some more details. The event was currently ran…

  • Excel doesn’t open CSV files correctly from sp_send_dbmail

    A nice little nugget today for anyone who uses SQL dbmail to send data in csv attachments. Sometimes, depending on your language settings, CSV files don’t open correctly in Excel. Excel ignores the ‘,’ and puts all data in column A. You then have to go through the hassle of closing the file and opening it throug the flat file wizard.   There’s a very nice solution to this that I found in this thread. It’s to…

  • Analysis Services Tabular or Multidimensional? A performance comparison

    Can SSAS Multidimensional be faster than SSAS Tabular for distinct counts on large datasets? We’ve all seen how fast the SSAS Tabular model can work – it’s an in-memory, heavily compressed analytics database. However you may have seen my previous posts on Tabular and NUMA, which show that at the moment Tabular is limited to a single CPU. This obviously limits its scalability and maximum performance. The situation A large…

  • LogParser Performance Inserting into SQL Server

    Recently I’ve been using LogParser a lot to import log files, such as W3C logs from an IIS web server. The distasteful format of these files is made palatable by the awesomeness that is LogParser; it just takes care fo it for you. (Check out this SQLBits session on LogParser by Jonathan Allen (Twitter | Blog) for a good intro to LogParser) However I’ve been suffering with very poor performance with large files, so started to…

  • Rock Paper Scissors Lizard Spock

    I want to share with you some genius level work by Phil Quinn (blog | twitter), who is furthering the boundaries of SQL Server.   Phil has taken the spatial drawing code from an earlier Frog-blog and used it to create a fully functional Rock Paper Scissors Lizard Spock game, just using the power of SQL Server. Not even the brightest boffins at Microsoft could ever have imagined that SQL Server would be able to provide such an awesome…
