SQL Server Database Project with SSDT

SQL Server Developer Tool also known as SSDT is a new Microsofft Tool debuting with Denali which is in CTP3. You need to install 'Juneau' to take advantage of this tool in Visual Studio. My previous post did not use the SQL Server Database project which was targeting DENALI but only previous versions. LocalDB is a feature of Denali which is to SQL Server as Cassini (the localhost in Visual Studio web applications) is to IIS.
Visual Studio 2010 does support LocalDB provided the new SQL Server Developer Tool (SSDT) is installed. After installing SSDT you need to create a SQL Server Database project as shown.

The SQL Server Database that is used within the project is the LocalDB. Here you can call up the table designer using Add Table as shown.

LocalDB table design in VS 2010 SP1

LocalDB is a feature of Denali CTP3 SQL Server Express. While you can connect to LocalDB, a file based database file, the designer data designer which is invoked from Data | Add New shown below does not support creating objects in SQL Server versions beyond SQL Server 2008 within the VS 2010.

It is interesting however; one can create database objects in SQL Server Express 2011 (presently Denali CTP3 Express) as seen in this image.

One can conclude therefore that VS 2010 SP1 needs some kind of upgrade before it can provide UI support for designing database objects in LocalDB.


The LocalDB has to be created directly in the application that uses the application instance of this database and not via the the connection in the Server Explorer.

Note added 9/14/2011
The upgrade that is needed is to install SSDT with the present code name 'JUNEAU'

SQL Express 2011 on the horizon

Presently it is Denali CTP3 Express from none other than Microsoft. A lightweight edition of Denali CTP3 which will eventually be released as SQL Server 2011 Express (I guess) like the other express editions of this great software. This is a 'made for web developers and asp.net developers" edition and make sure you download and enjoy working with it.
From the MSDN link here, http://msdn.microsoft.com/en-us/evalcenter/hh230763.aspx you can download Denali CTP3 Express edition which takes you to https://www.microsoft.com/betaexperience/pd/SQLDENEXPPRE/enus/ where you can make your choices as to version and language. Of course you need to register. The options are the same and one of the choices includes the tools as well.
The top features from the MSDN site are copied over here:
• Same database engine as other versions of SQL Server.
• Supports 10 GB of storage per database.
• Backup and restore with ease.
• Compatible with all editions of SQL Server and SQL Azure.
• Designed to work with Visual Studio and ASP.NET.
• Available with a graphical management tool.
• Offers reporting capabilities, full-text search, and spatial support.
What else do you need to test drive exccept the will?

Link to be bookmarked if you are using SQL Servers

You often come across a problem in your interaction with SQL Servers and you may often wonder where to go for help. This link gives you a list of other links that points in the right direction. Google, Bing or Yahoo search may ultimately lead you to the correct place, but why not look this one up first.

Build error related to SQL Express in Microsoft LightSwitch

The following message still shows up sometimes while creating and building Microsoft LightSwitch applications. This has not been rectified in the recently released RTM version as seen in the next paragraph.
Error    1    An error occurred while establishing a connection to SQL Server instance '.\SQLEXPRESS'.
Failed to generate a user instance of SQL Server due to a failure in starting the process for the user instance. The connection will be closed.    C:\Program Files\MSBuild\Microsoft\VisualStudio\LightSwitch\v1.0\Microsoft.LightSwitch.targets    157    10    BusinessTypeTest

However a work around exists which works very well. Here is the work around as suggested by Steven Hoag in his forum post.

  • Stop SQL Express from Control Panel
  • Close all LightSwitch apps
  • Move to the following location:
C:\Users\jay\AppData\Local\Microsoft\Microsoft SQL Server Data\SQLEXPRESS
  • Delete all the files in the SQLEXPRESS Folder.

However when you come to the step of deleting the files you may still get an error, that the files are being used by the SQL Server (despite the fact that you stopped SQL Express in the Control Panel).

To remove them go to the task master (Ctrl+Alt+Del) and bring up the WindowsTask Master window as shown.


Click End Process.


Click End Process for sqlserver.exe in the next window.

Now you can delete all files in the SQLExpress folder

After this start SQLEXPRESS and the previous application which threw the error should build without this error.

SQL Azure - July 2011 Service Release

In order to improve performance and scaling an update is in process spanning all the global data centers. The upcoming enhancements are not released but will be announced towards the end of the year. This is an important release as it targets the underlying engine. It is also important as it provides a common ground for SQL Azure and the near future release of SQL Server 11 - presently known with the code name  'Denali'.

The new release will support multiple data base administrators (Ye! Windows Azure is not going taking away your jobs, you just need to upgrade your skills). Also much better support for spatial data types making it a perfect fit for location aware apps both mobile and immobile.

The one thing that needs to be done on your side is the following: you should get hold of the latest version of SQL Server Management Tools, because the version number will change. Many users of lower versions might have already noted this while trying to connect to 'Denali' from older versions. The links to get the latest updates available in SQL Server 2008 R2 SP1 are:

    * SQL Server Management Studio (http://www.microsoft.com/download/en/details.aspx?displaylang=en&id=26727)
    * SQL Server Management Studio Express(http://www.microsoft.com/download/en/details.aspx?displaylang=en&id=26729)

If you are using SMO (SQL Server Management Objects) then you should get the
Cumulative Update package 7 for SQL Server 2008 R2                                                              (http://support.microsoft.com/kb/2507770)
When all is said and done your version of SSMS should have a version greater or equal to 10.50.1777.0 in order not to have connectivity issues.

This one is for SSMS that came with SQL Server 2008 R2: No good!

This one is for SSMS installed when CTP1 'Denali' was installed:

Clearly if I use the above I should not have any connectivity problems.

If you are a DBA trying to upgrade your skills to understand SQL Azure, my book is a must read. You could get a free copy by sending an email to me at mysorian@gmail.com with 'SQL Azure' in the subject line. Who knows you may be lucky and get a book or a ebook in the raffle.

Review of my SQL Azure book from a SQL Azure developer

Anton Staykov (http://www.staykov.net) was a frequent visitor to the SQL Azure Forum when SQL Azure appeared on the web. Anthony is a Microsoft MVP from Bulgaria. I was also a frequent visitor trying to learn from others about SQL Azure. Recently, I saw his review of my book (http://blogs.staykov.net/2011/03/sql-azure-enterprise-application.html) which described some positive aspects of my book. He was kind enough to permit me to reproduce his review to the visitors of my blog.
Here it follows:

SQL Azure: Enterprise Application Development reviewed
"As I blogged earlier this year, there are two books on Windows Azure from Packt publishing. I was personally involved as technical reviewer with one of them, and now I am sharing my feedback on the second.
Microsoft SQL Azure: Enterprise Application Development, is the second one from the "Azure" series. Published right after the "Microsoft Azure: Enterprise Application Development" the book is the perfect complement to it. Reading Microsoft SQL Azure, you will learn the basics of cloud services (i.e. what is a Cloud, what types of clouds are there and who are the big players). You will, of course catch up with Windows Azure, as it is briefly described, in case you missed the "Microsoft Azure" book.
Focusing on the SQL Azure service it self, the book covers all the steps required for you to leverage a cloud based RDMS. All the information you find there is well structured and accompanied with good number of screenshots and sample SQL statements. You will not miss any of the features delivered from SQL Azure. All the answers are there – what is the security model of SQL Azure; how to connect and execute queries against the cloud (how to use Sql Server Management Studio); how can you use Sql Server Integration Services (a.k.a. SSIS) and what are the limitations; how to sync your cloud data with on-premise data; what are the tools supported by SQL Azure; and more and more questions and answers. I could hardly find a question for SQL Azure that this book does not answer!
I would highly recommend this book as a complement to the "Microsoft Azure: Enterprise Application Development". These two books are the complete guide to develop application for the Microsoft's Cloud! "

It is still not too late you may enter the raffle and win a hard copy or a eBook. Just send an email to mysorian@gmail.com with SQL Azure in the subject line.

New article on the SQL Azure 'Houston' Project

 Read this 'How-to' article on the Packt Site.

The 'Houston' project was one of the incubation projects of the windows Azure cloud services. This project has entered into production and you will find it in the new Windows Azure Portal (https://windows.azure.com). All New services can be accessed from the 'Ribbon' under Common Tasks.


This article is about the 'Houston' project when it was still in incubation. You can still access the labs portal(http://www.sqlazurelabs.com/). In this article some of the features of this web based tool as well as how carry out few of the basic tasks are described. Houston project provided the following basic database management tasks:

•Authoring and executing queries
•Designing and editing database schema
•Editing table data

Readers are encouraged to read my comprehensive book on SQL Azure.  Also you may enter a raffle to win a copy of the book.

No connection to SQL Server Compact from Microsoft SQL Server 2011

There appears to be no way to connect to SQL Server Compact using the SSMS installed with SQL Server 2011 (Denali). There is however a menu item that indicates that one should be able to connect but it stops there. This menu item when chosen does not provide a SQL Compact Editor icon which used to be available in earlier versions.

The !sorry Mozilla you could not show this (Firefox Version 3.6.13.)!  button (the last item in the drop-down list) in the 'Connect to Server' window used to have an opening to the file system to find the SQL Server Compact files if there were any. But this not possible as you can only browse for servers and not files in the new SSMS.

What is the latest MySQL Version available?

The latest version for Windows (x86) version of MSI installer can be found here: https://dev.mysql.com/downloads/windows/installer/ ...
