For those who haven't heard already, the news is out that Microsoft SQL Server 2008 Katmai is planned to have Spatial support both Flat Earth - what we commonly think of when we think of projected data and standard spatial reference systems and original OGC SFSQL Standard, as well as Geodetic support primarily to deal with geometries that span the globe. This is expected to ship sometime probably in late 2008. They are a bit late considering PostGIS, Oracle Spatial, DB Spatial Blade and MySQL have already introduced spatial support in their database systems. Better late than never.
I've created this space here - mostly to collect interesting tid-bits on the debates, grumbles, hoorahs, and updates going on about this topic.
I have been a long believer in the power of GIS Spatial Analysis and predict that it will become mainstream and ubiquitous just as the web, relational databases, and browsers have become. I am proof of that since I am not a Geographer or GIS Analyst but a database administrator/Database application programmer and Systems Analyst who got involved in this area out of necessity. I predict in about a year or less, the separation between the GIS community as we know it and the general database programmer, BI, Engineer and Scientist crowd will be fused. The fact that Microsoft is finally introducing spatial in their commodity database will only reinforce that end. The revolution is going into full force.
These will be truly interesting times. Hopefully all factions can learn a lot from each other and no one will get hurt in the cross-fire except for some truly annoying people.
General Commentary on SQL Server 2008 Katmai Spatial
SQL Server 2008 Katmai June 2007 CTP is out
This is the third Community Tech Preview of Katmai.
Unfortunately it appears that this June 2007 CTP version is also lacking Spatial support based on Directions Magazine Interview with Ed Katibah, spatial program manager for SQL Server. So I guess probably a couple CTP versions later, we may see this promised feature. The interview with Ed Katibah is still worth a read to find out more details about the pending spatial enhancements and to see snippets of what sql using this new feature will look like.
Note the sql syntax of the new SQL Server 2008 spatial features takes the object-oriented approach verses the functional approach.
So you will be writing
Back to SQL Server 2008 topic
SELECT s.id, s.name, z.zipcode
FROM streets s, zipcodes z
WHERE s.shape.STIntersects(z.shape) = 1 AND
SELECT s.id, s.name, z.zipcode
FROM streets s, zipcodes z
WHERE STIntersects(s.shape, z.shape) = 1 AND
Warning: Major diversion from SQL Server 2008 Spatial topic coming up
I think I prefer the functional way in a system that allows functional overloading for these kind of use cases. When I was a devout Smalltalk programmer, I would have scoffed at anything that wasn't object-oriented and then I grew up a little and noticed situations when object-orientation was a hinderance. Then I became a java programmer and was offended by what I considered to be a misuse of object-orientation in certain cases. For some reason it worked in Smalltalk probably because of its dynamic typing and its proposition that not only were objects the most important thing, but they were the ONLY thing that existed. Because methods, blocks of code and classes themselves were objects and could be manipulated like any other, Smalltalk had an immense expressive power ideal for modeling and doing "think out of the box" like projects. I'm glad to see that Smalltalk is making a comeback.

Please note - in order to see the download link for the actual SQL Server 2008 CTP product, you have to register for the CTP program by clicking on the My Participation link on the SQL Server 2008 CTP page. It will ask you to first create a Microsoft passport account if you don't have one already. Registering is free of charge.
SQL Server 2008 July 2007 CTP is finally out with I think 1 hour to spare
This release still doesn't have any spatial support, but at least they have provided us with a nice diagram of what is in there. Take a look.
SQL Server 2008 November 2007 CTP is out and has spatial support
You can download the November CTP 2008 at Microsoft SQL Server 2008 CTP, November 2007.
If you don't want to go thru the hassle of installing SQL Server 2008 CTP or don't want to mess up any of your existing installs, you can use the Microsoft SQL Server 2008 Nov 2007 CTP Virtual 2005 VHD version available.
The books online for this CTP is available at SQL Server 2008 Books Online Community Technology Preview (November 2007)
In addition to the long awaited spatial support, the November CTP 2007 for SQL Server 2008 also contains ability to store large BLOBs of data to the NTFS file system and yet still query this portion of the file system as part of the database.
Big Uproar - Is it Lon/Lat or Lat/Lon?
In the news, there are rumbles going on about how Microsoft SQL Katmai violated common GIS convention by outputing WKB and WKT as Lat,Long instead of Long, Lat.
SQL Server 2008 February CTP is out and has spatial support
The Febraruary 2008 Katmai CTP was released on February 19, 2008. This version does not have the LongLat fixes that will make the GIS world happy. This CTP can be downloaded from
