SQL Server (Denali)-CTP1

I downloaded the SQL Server Denali CTP1 version fro MSDN and began the installation process. The first thing i came across was that my OS was not up to the required level. I found out based on the requirements that if one has vista then SP2 needs to be applied. Once the SP2 was accomplished went through the setup process. It was very similar to the setup of sql server 2008 R2 version. On completion of the setup launched the Management studio, in the splash screen it displayed Powered by Visual Studio at the right hand corner. It gave an indication that the UI of SSMS is going to be more tied in with visual studio 2010. I have just begun to play around with queries in Denali,one of features that has been enhanced is Intellisense, there are more options in the Intellisense menu. I will planning to provide more updates as i explore the features of Denali. I also installed the BIDS, Integration services and reporting services components of denali.

SSRS-Report Portal...

I recently installed SQL Server 2008 on my laptop which included SSAS,SSIS and SSRS. I installed SSRS in the native mode configuration. I had to work on developing reports in SSRS and deploy the reports. I developed the Reports in BIDS and was ready to deploy the reports on my localhost report portal. When I tried to deploy the reports i got an error saying my account did not have access to the portal. I launched Internet Explorer as an Administrator and I was able to get to my localhost report portal. Once i got to the site, there were two tabs contents and properties. I clicked on the properties tab and added my account as a Content manager and saved the settings. Once this was complete, I went back to BIDS and deployed the report, the report was successfully deployed to my report portal.

Error Handling...

One of the aspects in T-SQL development, especially with writing stored procedures is Error Handling. It is important to trap errors, log the errors and provide a proper exit from a stored procedure. One of concepts which was introduced in the .NET framework, has been incorporated into T-SQL. It is the BEGIN TRY..END TRY and BEGIN CATCH..END CATCH block. this feature allows one to keep the code blocks within the stored procedure modular. Here is an example of the use of TRY CATCH block within the stored procedure.
      INSERT INTO tablea
      SELECT col1,col2,col3 FROM testtable
      INSERT INTO table_error_log
     SELECT ERROR_NUMBER() AS ErrorNumber,
      ERROR_SEVERITY() AS ErrorSeverity,
      ERROR_STATE() as ErrorState,
      ERROR_LINE () as ErrorLine,
      ERROR_PROCEDURE() as ErrorProcedure,
      ERROR_MESSAGE() as ErrorMessage

One of the neat things while using the CATCH block is the availability certain standard functions which provides the Error Procedure and Error Message. These functions can provide valueable information about the Error.
