Speaking at VSLive again down in Orlando, Florida. Should be a great show. I am speaking on SQL Server 2005 topics, hope to see you there.

TSQL Enhancements
Stephen Forte, Corzen, Inc.
10:30 a.m.

By now you have heard that you can write stored procedures in C# and VB . NET for SQL Server 2005. Does that mean TSQL is dead? NO! A lot has changed in the world of TSQL with the next version of SQL Server. See how efficient you can become with the new TSQL enhancements. You can crosstab in seconds with the PIVOT statement, perform recursive queries much easier with Common Table Expressions, manipulate XML data easier with the XML datatype and aggregate with ease using the new TOP functions. Report with ease with ranking functions. We’ll take a look at the new TSQL enhancements, data types, and the like. We’ll also look at how to choose between CLR Stored Procedures and TSQL.

Data Analysis Using Ranking and Windowing Functions
Stephen Forte, Corzen, Inc.
11:45 a.m.

SQL Server 2005 adds the functionality of a ranking expression that can be added to your resultset that is based on a ranking algorithm being applied to a column that you specify. This will come in handy for reporting and in .NET applications for paging and sorting in a grid as well as many other scenarios. We’ll explore the ROW_NUMBER() function, which assigns a running count to each row and compare it to RANK() and DENSE_RANK(). Use these functions to solve complex SQL Problems. Then we’ll look at custom percentile ranking using NTILE() and look at business and academic applications of NTILE. Lastly, we’ll apply windowing functions to all of the four ranking functions with PARTITION BY to perform hard code aggregate functions. 


 Mobile Enterprise Applications with SQL Server 2005 Mobile Edition
Stephen Forte, Corzen, Inc.
4:30 p.m.

Using SQL Server 2005 Mobile Edition and Visual Studio 2005, Microsoft has made developing applications for the Windows SmartPhone and Pocket PC devices as easy as developing conventional Windows and Web applications. The .NET Compact Framework and SQL Server Mobile give you full functionality on the device with the ability to perform Merge Replication with a back-end SQL Server. This session will help you leverage your existing .NET and SQL Server to build mobile enterprise applications from scratch that can dynamically update a backend SQL Server or work offline and synchronize later.

I know that all my firends in Pakistan read my blog, and let me say my heart goes out to you. You and your country really touched me on my most recent visit.

While most of my firends are safe in Karachi, I had to search for Saqib Ilyas in Lahore, much closer to the epicenter. Thankfully he is ok.

My buddy Fahad Majeed reports about the earthquake here.

You can donate here.

SQL Server 2005 allows you to store XML in a native data type. That is cool, however, having XML in the database is almost useless unless you can query the elements and attributes of the XML data natively. XQuery becomes very useful when you can use it to search based on the values of a particular element or attribute. The xml.exist() function accepts an XQuery as input and returns 0, 1, or NULL, depending on the result of the query; 0 is returned if no elements match, 1 is returned if there is a match, and NULL is returned if there is no data to query on. For example we will verify if a node exists in this particular XML string of classes.


Set @XML='


   <class name="SQL Server Index"/>

   <class name="SQL Precon"/>



Select @XML.exist('/classes')


The code above returns a 1 since the “classes” element exists in the XML variable. If you change the XQuery expression to search for an XML node that does not exist like,  Select @XML.exist('/dogs), then it will return 0.

You can see this in action as part of a CHECK CONSTRAINT. SQL Server will not allow you to use an xml.exist as part of a CHECK CONSTRAINT. So you have to first create a user defined function (UDF) to perform the action. This UDF accepts an XML field and retunes the value of an xml.exist() method looking for an instance of < Orders'>:

USE AdventureWorks


CREATE FUNCTION dbo.DoesOrderXMLDataExist        

(@XML XML)                    

RETURNS bit                       



RETURN @XML.exist('/Orders')   




            To use this UDF as a CHECK CONSTRAINT, just create a table and pass the column you want to apply the constraint to the UDF you just created.

--create the table using the function



   xOrders XML NOT NULL Default '<Orders/>'

 CONSTRAINT xml_orderconstraint


Its that simple, now you have a rule enforced on that column making sure that an <Order> element is added to this table.

That was my time for a mile in the race this weekend down 5th Avenue. In some respects a mile that fast was harder than the marathon. Headed out to Redmond, Washington to visit the boys at Microsoft at the MVP Summit. Should have some good stories to tell in the old blog while I am out there.

This Sunday I am going to see the Dalai Lama speak at Rutgers University. The topic is “Peace, War, and Reconciliation.” I am curious to see how he approaches the topic of China and Tibet.


Not being a fan of Richard Gere I do find the Chinese occupation of Tibet wrong. I can say this having visited the region several times and spending a lot of time there making friends with the locals in Tibet, Bhutan and Nepal. I hope the Dali Lama speaks to this.

Three and a half years ago I scaled my first peak in the Catskills and was hooked to get into the exclusive Catskill 3500 club. The 3500 club is someone who has climbed all 35 peaks of 3500 feet elevation in the Catskills, including 4 of them twice in the winter. You may say, that is easy, but considering that 18 or so of them are trail less and the Catskills can have a foot of snow as early as October 1 and as late as May 1.


Well I did it! It did take me long enough since I got diverted by the mountains in Bhutan, Machu Picchu, Everest, Denali, Mt. Rainer (twice), Kilimanjaro and a marathon in some strange land of Antarctica.


So in all of those crazy treks, Nepal is my favorite country (people, scenery, Buddhist culture), Rainer is my favorite, and Kilimanjaro is the one most likely to do more than once.


In the Catskills, I would do almost any of the mountains over again (and will do a bunch this winter) and most likely will start climbing some peaks in the White Mountain Range in NH.


So here are the peaks:



Slide (2/9)

Balsam (2/24)

Hunter (6/2)

Southwest Hunter (6/2)

Black Dome (9/8)

Thomas Cole (9/8)

Blackhead (9/8)

Graham (9/29)

Balsam Lake (9/29)

Panther (11/10)

Blackhead (1/12)

Big Indian (3/13)

Eagle (3/13)

Westkill (3/23)

Table (4/19)

Peekamoose (4/19)

Indian Head (10/4)

Twin (10/4)

Sugarloaf (10/4)

Pleatu (10/4)

Katterskill High Peak (10/25)

Bearpen (10/26)

Vly (10/26)

Friday (5/15/05)

Rusk (7/16/05)

Halcott (09/17/05)

Back from China and ready to start the fall marathon season in New York along with the usual list of conferences, MVP Summits and the like.


A very quick synopsis on China, well it was pretty cool. Got to experience communism first hand (and made me not take for granted the freedoms I have as an American) and see some amazing historical, religious and cultural areas. I met so many everyday Chinese people, very excited to practice their English talking with me for hours and exchanging views and ideas.


While I went to several places in China (Beijing, Datong, Dunhuang, Xi’am, Shanghai, Hong Kong and Macau), I have to say two places really stuck out for me.



First is the Great Wall. It lives up to its reputation. It is steep, vast and goes on and on and on. I kept climbing on up, seeing in the distance a watchtower and figured to myself “well this watchtower should be the last one, I can then view over the other side of the mountain.” Then when I got there, there were just more and more and more. A truly amazing experience.


Second is the Yungang Caves, just outside of Datong in the Shanxi Province. These caves were carved out of a mountain by Buddhists 1500 years ago (yes 1500) and are a very special place-it was a bit of a pilgrimage for me. Started in 450 AD, Yungang is a relic of the Northern Wei Dynasty (386-534). It is a combination of Chinese and  Indian Gandhara Buddhist art. Chinese are not like the Buddhists in other parts of SouthEast Asia that are Theravada, the Chinese are Mahayana.


Anyway, I saw a ton of other great stuff, but don’t want to bore you all with the details. Time to get back to the Model View Controller Design pattern…..

Today we woke up and visited Mao’s Tomb. A brutal reminder that while economically free China is still a one party state without any elected government.


Climber the Great Wall, visited the Forbidden City and Summer Palace (which rocks), of course a visit to a Buddhist Lama temple rounded out some time in Beijing.


Now I am in Datong, where no English is spoken at all. Visiting some old Buddhist Caves and Monasteries tomorrow before off to Xiam to see the warriors.

(This does not suck)
