32-Bit ODBC Drivers in Windows Server 2008 R2

Lately I’ve been taking advantage of my MSDN subscription (thanks to Ken Simmons‘ competition last month) and playing with some new technologies, initially experimenting with Windows Server 2008 R2. If you hadn’t heard prior to launch period, Microsoft made 2008 R2 64-bit only – probably the right decision to make but whilst the software industry is still making a transition from 32-bit to 64-bit there are bound to be some niggles here and there.

Being a database guy, one of the issues I noticed right away was that the ODBC Data Source Administrator accessible via Control Panel / Administrative Tools is the 64-bit version and can only be used to setup connections for 64-bit ODBC drivers. Not only was the 64-bit version missing the Postgres driver I had just installed, there were no drivers at all other than SQL Server…

It turns out that there are are two, entirely identical ODBC tools and the one that most of us will end up using initially (unless we’re lucky enough to have an all 64-bit architecture) is kept in the basement that is the c:\Windows folder. The 32-bit ODBC Data Source Administrator can be found by going to the Start Menu, selecting Run and executing c:\Windows\SysWOW64\odbcad32.exe as follows…

Once launched, you’ll see a tool that appears to be identical in every way, except that the ‘missing’ ODBC drivers are now available…

Please note that you can’t run both 32-bit and 64-bit tools at the same time so please make sure you close the 64-bit one first, it’s also worth bearing in mind that if you’re running 32-bit applications they will probably be looking for 32-bit DSNs so even if you can get a 64-bit driver for your data source it doesn’t mean that it’s the right thing to do.

As much as I understand Microsoft’s decision to stop developing 32-bit operating systems, a little bit of a helping hand during the transition period would’ve been nice - perhaps a second shortcut in the Administrative tools folder and the ability to run them simultaneously?  The whole thing seems like a confisuing mess in their own words…

The 32-bit version of the ODBC Administrator tool displays 32-bit system DSNs, 32-bit user DSNs, and 64-bit user DSNs. The 64-bit version of the ODBC Administrator tool displays 64-bit system DSNs, 32-bit user DSNs, and 64-bit user DSNs.  

To maintain backward compatibility, no resolution for this problem is currently available… to work around this problem, use the appropriate version of the ODBC Administrator tool.

I’ve made my own shortcuts to the 32-bit version and if you’re like me and constantly diving in and out of ODBC Administrator then you’ll probably want to do the same.

My Favourite SQL Server Features

SQL Server MVP Ken Simmons is offering the chance to win one of three MSDN subscriptions on his blog, I thought I’d join in by writing a post describing my favourite features of SQL Server.

The ‘big ticket’ item for me is SQL Server Integration Services. For those of you stumbling across this post from non-SQL backgrounds SSIS is Microsoft’s ETL tool and has been bundled with the database engine since SQL Server 2005. Essentially SSIS allows you to extract data from (or deliver data to) a range of ODBC, OLE DB, ADO.NET or flat file data sources including Oracle, DB2, MySQL, Excel, CSV files and of course – Microsoft SQL Server. Along the way you can make use of a range of tasks and components that allow you to transform the data and perform operations such as looping, FTP, Email, Lookup Values, Data Mining, Aggregation, Process Dimensions and many many more .  There are alternatives out there but many are prohibitively expensive for the small-medium enterprise (e.g. Informatica, BODI) – that SSIS comes bundled with SQL Server still astonishes me to this day.

As for my favourite ‘little’ features I’d have include:

Linked Servers, a few people give it a bad rap since they can be misused but I’ve made great use of Linked Servers to simply data assurance processes and join data in queries running across both MySQL and Sybase data sources in a single statement.

Copy and Paste Coloured SQL, I’m not sure if it’s just because I’m used to Management Studio but I often struggle to read SQL if it’s not coloured-in. Colouring SQL improves readability and since SQL Server 2005 I’ve enjoyed the ability to copy and paste directly from Management Studio into emails or word documents and retain the coloured keywords, it makes documentation much more interesting.

Common Table Expressions, it took me a while to get into the swing of using CTEs and then for a while I probably over-used them before settling down. They’re often a great way to make statements with nested subqueries much more readable and much more elegant in design but whenever I go back to SQL Server 2000 or MySQL I really miss CTEs.

SQL Server Express, it might be a bit of a cheat to include an edition as a feature but the fact that the core SQL Server database engine is available for free is brilliant and allows a lot more people to try out SQL Server and see the difference between a slick GUI like Management Studio Express vs the MySQL toolset.

Intellisense, I couldn’t resist choosing this as one of the more modern features I love about SQL Server. Once you’ve gotten used to it Intellisense makes trotting out T-SQL statements a breeze and you know what? It just feels cool, albeit in a really geeky sense of the term.

How to Identify your SQL Server Version and Edition

I was just updating the Software Asset Register at my company and to do so I had to look at all of the SQL Servers in the business and find out the version and importantly the edition (Standard vs. Enterprise).   

I’d always used:  SELECT @@VERSION but I came across a Microsoft article showing an alternative:  How to Identify your SQL Server Version and Edition that shows another method using the SERVERPROPERTY() function.  As an example, I used the following: 

SELECT SERVERPROPERTY(‘MachineName’)    AS MachineName,
       SERVERPROPERTY(‘ServerName’)     AS ServerName,
       SERVERPROPERTY(‘ProductVersion’) AS Version,
       SERVERPROPERTY(‘ProductLevel’)   AS Level,
       SERVERPROPERTY(‘Edition’)        AS Edition,
       SERVERPROPERTY(‘IsClustered’)    AS IsClustered,
       SERVERPROPERTY(‘Collation’)      AS DefaultCollation,
       SERVERPROPERTY(‘LicenseType’)    AS LicenseType,
       SERVERPROPERTY(‘NumLicenses’)    AS NumLicenses 

You can read more about the possibilities of that on the MSDN SERVERPROPERTY() page.

Microsoft’s UK Tech Days: SQL 2008 R2

I enjoy going to SQL Server community events, I usually find they provide a refreshing look at what other people are doing and provide inspiration and ideas of what I could be doing myself.  Vendor-run events are different so I attended Microsoft’s SQL Server 2008 R2 Tech Days event with mixed expectations, not sure if it was going to overly marketing-heavy or whether it really would be worth taking a day out of the office.

Thankfully I was in luck, Microsoft did a great job of treading the line between promotion and information and whilst the intro and the first 5-10 mins of each take were quite marketing oriented the majority of the content was realistic and provided honest demonstrations of the product.  Also throughout the talks presenters were offering to answer questions via SMS or via the Twitter hash-tag #uktechdays, this was a great touch and even though there wasn’t time to answer all of the questions it really added to the interactivity of the event.

First up was Power Pivot, as a product it looks to be immensely powerful and provides lightning fast analytical capabilities though I imagine it needs a decent amount of RAM and an up to date processor to achieve it – the most amazing part is that it’s a free add-in for Excel 2010!  Essentially PowerPivot allows you to extract up to a million records from a database and perform in-memory analysis with that set of data, including combining it with other data sets, combining it with data in your spreadsheet, performing calculations, making summaries, etc.  It’s well worth taking a look at the demos, PowerPivot is a massive leap forward in Excel’s capabilities but to me it seems like a step backwards in terms of the centralised BI ‘single version of the truth’ concept – allowing users to rip a million rows out of the Data Warehouse, mix them up with other data sources and then send them around via email or even publish them via SharePoint.  As it goes the Share Point integration was also pretty remarkable, allowing other users to use published reports not only for viewing but also as a data source on which to build new reports – pretty ground breaking stuff but I’d hate to be the guy debugging a report based on a report based on a report based on… (you get where I’m going).  Overall I’d give PowerPivot a 5* rating for innovation but it seems that Microsoft is using a common tactic from Formula One – trying to get ahead of the competition by taking a contrary strategy, but will it turn out like Jenson Button in Shanghai (he won) or like Lewis Hamilton in Australia (he didn’t)?

After a relatively dry talk on virtualisation and Hyper-V Live Migration (impressive stuff but I’ve seen it before) the next talk was about Report Builder 3 and having never been a user of Reporting Services I thought I was just going to sit through it and twiddle my thumbs – I was wrong.  Having been knocking about in the BI world for about 8 years or so I can really say that this release of Report Builder really cements Microsoft’s position in Business Intelligence.  It’s still not very slick from a usability standpoint but the visualisations they’ve added are stunning and having been a long-time user of Business Objects the talk actually did make me think “how hard would it be to switch?” – since I have a mature installation the answer is very hard but it still made me think.  The most impressive visual elements were the Spark Lines, Data Bars and Indicators but the maps were also pretty good especially given that you can use ESRI shape files.

The next talk was “Maximising your existing hardware CPU, memory and disk” by Ramesh Meyyappan, I’ve seen Ramesh before at SQLBits and he’s always very good, very detailed and straight to the point.  It was a great talk, taking place mainly in Management Studio rather than PowerPoint and if you get the chance to see one of Ramesh’s talkes in the future you should definitely go (but have a cup of coffee first).  Following Ramesh’s rollercoaster of a talk was much more relaxing run-through of Microsoft’s ‘database in the cloud’ offering SQL Azure, a product I find extremely interesting but don’t have an immediate use for though I expect in time as the feature-set converges with SQL Server I will be changing my mind.  Next up was StreamInsight, R2′s Complex Event Processing (CEP) solution for analysing large data streams (10k rows/sec+) on the fly without touching the relational engine – it looks interesting but I don’t have those sorts of requirements at the moment so I don’t have much of a reaction.  The day was rounded off by a presentation by Andrew Fryer about Master Data Services, a difficult topic to present in a jazzy way but it looks very interesting and if it will integrate with the spaghetti-junction of systems floating around in most organisations it could do a lot to help us keep our data warehouses in line with corporate naming conventions, it sounds like a lot of fuss over a little issue but if you’ve ever actually tried to solve the problem yourself in a company with more than a couple of source systems you’ll understand how hard it can be.

All in all a good day, I’ll give a shout out to the staff at Jumbucks in Shepherd’s Bush where I had breakfast and bought a bagful of Australian confectionary and to the Vegetarian Chinese buffet over the road for providing me with much needed sustenance.
