SQL Server 2012 Master Data Services Error: The required .svc handler mappings are not installed in IIS.

Microsoft SQL Server 2012 Release Candidate 0 (RC 0) has a confirmed issue with Master Data Services configuration. The following error is raised by the Master Data Services Configuration Manager when launched:

Before creating an MDS web application, you must correct the following errors:
Internet Information Services (IIS) is not configured on this server.
The required .svc handler mappings are not installed in IIS. For more information, see http://go.microsoft.com/fwlink/?LinkId=226284.
For web application requirements, see http://go.microsoft.com/fwlink/?LinkId=215355.

This issue has been communicated to Microsoft via Connect ID: 701993 and is documented in the Technet Article “Troubleshoot Installation and Configuration Issues (Master Data Services in SQL Server 2012)”

The Workaround

After several days trying to figure out the issue, today I received notice from Reagan Templin (LinkedIn | Twitter), technical writer for Microsoft, that the MDS Team has identified the issue. This issue will NOT be fixed in the current RCO but will be fixed in the RTM version. The error can be replicated under the following conditions:

1. Configuring Master Data Services on a server that is not joined to a Windows domain
2. Running Master Data Service Configuration Manager with a local account (non-domain user) on a server joined to a Windows domain.

The workaround is simply to join the server to a Windows domain and launch Master Data Services Configuration Manager with a domain account that has administrator privileges. In my case,  after I joined the server to a domain I was able to complete by MDS configuration.

Many thanks to Reagan Templin for her above and beyond customer service. She followed up on this issue directly with the MDS Team after I posted a message on Twitter about the issue I was having and kept me posted with updates towards resolving the issue.

SQL Saturday 86 BI Edition Tampa 2011: Afterthoughts

Wow! Just Wow! That’s all I can say to describe how great SQL Saturday 86 was on November 5th in Tampa, FL . I got so much positive feedback from every attendee, speaker and sponsor. Food was great, sessions were amazing, speakers were first class!  I have to say thanks to everyone for attending, speaking, sponsoring and helping out with these great event put together by the Tampa Bay Business Intelligence User Group officers and volunteers.

Organizing Committee & Volunteers

I cannot take personal credit for this event. It was truly a team effort. Somewhere I read that in order to be successful you need to surround yourself with talented & driven individuals that are committed to your same goals.

Speakers

Our speakers were world class speakers to say the least. The speaker roster included Microsoft MVPs, field engineers and evangelists and other professionals that committed their time and paid for their own travel to support our event. We had just a few speakers that cancelled for personal, health or work-related conflicts. We still want to express our appreciation to them for willing to support our event as well. Thankfully, we managed to secure alternate speakers who did a great job even though it was last minute. Thank your SQL Saturday #86 Speakers!

Sponsors

Our sponsors made our event a quality and epic event by sponsoring with cash, items and swag to giveaway. Thanks to them we were able to sponsor great Cuban food from LATAM restaurant, coffee and donuts throughout the day, swag and raffle prizes and provide our speakers with a thank you dinner.

To all our sponsors thank you for supporting our SQL Server and Business Intelligence Community!

Panel of Experts

In this event I decided to put together a panel of experts to discuss several topics relating to SQL Server and Business Intelligence as well as a discussion of what’s new in the upcoming release of SQL Server 2012. The Panel of Experts took place at LATAM restaurant right after lunch. Our panel of experts included:

• Adam Jorgensen, Pragmatic Works (Twitter | LinkedIn | Blog)
• Brian Mitchell, Microsoft (Twitter | LinkedIn | Blog)
• Sanjay Soni, Microsoft (Twitter | LinkedIn| Blog)
• Michael Antonovich, Orange County School District (Twitter | LinkedIn | Blog)

We invited our sponsors to briefly talk about their products and services and prizes they were giving away during the event. Following our sponsors I decided to recognize Andy Warren, MVP and PASS (Website) Board of Directors, for his contributions to the SQL Server community, SQL Saturday creation and 100 SQL Saturday milestone.

BI BootCamp pre-conference

Along with our free SQL Saturday #86 event we hosted a paid pre-conference titled “BI BootCamp” presented by SQL Server MVP and SSAS Maestro Instructor Adam Jorgensen. We exceeded our goal with 33 attendees paid attendees, all of which gave very positive feedback of Adam’s presentation. I did a star appearance, helping Adam present a section on SSRS Reports using OLAP cubes as a source.

Thanks to Mike Wells for (Twitter | LinkedIn | Blog) for taking pictures throughout the event. You can see more event pictures at:

The CASE of the missing non-NULL T-SQL Error: None of the result expressions in a CASE specification can be NULL.

Recently, while doing some data scrubbing for a customer I got an interesting error in SSMS with one of my CASE statements. The error received was:

None of the result expressions in a CASE specification can be NULL.

It was a long T-SQL script (and a long night) and could not understand the error message. After a couple minutes BinGling (Google +Bing) around the web, I still could not find the root cause, so I decided to comment out every single CASE statement and run one by one until I pinpointed the offending syntax.

 

To my surprise, the issue was very simple, yet undocumented. The T-SQL syntax I was writing was somewhat as follows:

 

SELECT ProductID,

CASE WHEN SerialNumber like ‘X%’ THEN NULL

WHEN SerialNumber = ‘0’ THEN NULL

WHEN SerialNumber = ‘-‘ THEN NULL

WHEN SerialNumber = ‘Unknown’ THEN NULL

END AS SerialNumber_Clean

FROM tblProduct

 

After executing this script the error mentioned above is raised. The same error is raised even if we rewrite the script as a simple CASE statement:

 

SELECT ProductID,

CASE SerialNumber

WHEN ‘0’ THEN NULL

WHEN  ‘-‘ THEN NULL

WHEN ‘Unknown’ THEN NULL

END AS SerialNumber_Clean

FROM tblProduct

 

So what if we add an ELSE statement as follows:

 

SELECT ProductID,

CASE WHEN SerialNumber like ‘X%’ THEN NULL

WHEN SerialNumber = ‘0’ THEN NULL

WHEN SerialNumber = ‘-‘ THEN NULL

WHEN SerialNumber = ‘Unknown’ THEN NULL

ELSE NULL

END AS SerialNumber_Clean

FROM tblProduct

 

We still get the same error. The issue as the raised error describes can be narrowed down in that you cannot explicitly return NULL for every resulting expression. There must be at least one non-explicit NUL in the resulting expression. For example, we can rewrite the script correctly as follows:

 

SELECT ProductID,

CASE WHEN SerialNumber like ‘X%’ THEN NULL

WHEN SerialNumber = ‘0’ THEN NULL

WHEN SerialNumber = ‘-‘ THEN NULL

WHEN SerialNumber = ‘Unknown’ THEN NULL

ELSE SerialNumber

END AS SerialNumber_Clean

FROM tblProduct

 

As you can observe, adding an ELSE statement that does not return another explicit NULL makes the script work and as a matter of fact, should be the correct syntax. Interestingly, ELSE is not necessary to make the script valid. The script will run even without an ELSE expression, but only if at least one of the resulting values is not an explicit NULL. The following script runs successfully (notice no ELSE):

 

SELECT ProductID,

CASE WHEN SerialNumber like ‘X%’ THEN NULL

WHEN SerialNumber = ‘0’ THEN NULL

WHEN SerialNumber = ‘-‘ THEN NULL

WHEN SerialNumber = ‘Unknown’  THEN NULL

WHEN SerialNumber = ‘No Serial’ THEN ‘Non-Serialized Product’

END AS SerialNumber_Clean

FROM tblProduct

 

Books on Line should include this caveat on their documentation. http://msdn.microsoft.com/en-us/library/ms181765.aspx

 

The following sections should be modified as follows:

THEN result_expression

Is the expression returned when input_expression equals when_expression evaluates to TRUE, or Boolean_expression evaluates to TRUE. result expression is any valid expression. If no else_result_expression is specified or if else_result_expression is set to return an explicit NULL, at least one result_expression has to be specified to return a non-explicit NULL.

 

ELSE else_result_expression

Is the expression returned if no comparison operation evaluates to TRUE. If this argument is omitted and no comparison operation evaluates to TRUE, CASE returns NULL. else_result_expression is any valid expression. The data types of else_result_expression and any result_expression must be the same or must be an implicit conversion and at least one of them should be specified to return a non-explicit NULL.
