What is the default isolation level (SQL Server 2008)

Posted By:      Posted Date: August 29, 2010    Points: 0   Category :Sql Server
Hi, My database settings are: SET ALLOW_SNAPSHOT_ISOLATION ON READ_COMMITTED_SNAPSHOT ON Does this mean I don't have to explicitly have: Set Transaction Isolation Level Read Committed for each proc, i.e. because I have the two settings at the database level there is no need set the Transaction Isolation Level in each proc or does this need to be done as well as the database level settings.

On SQL_Latin1_General_CP1_CI_AS SQL Server 2008 Default Collation


Collation is one of the most confusing features of SQL Server. BOL 2008 states that backward compatibility is the only reason to go with SQL collation. I thought previously it is just smart to stay with the default Microsoft offers unless there is a real good reason to choose a different collation.

So is the default SQL_Latin1_General_CP1_CI_AS  (Case Insensitive, Accent Sensitive) a good choice? (Assume the installation is brand new SQL Server 2008)

Related links:

SQL Server offers the SQL_Latin1_General_CP1_CI_AS collation as the default collation for server installations.

For backward compatibility, the default English-language (US) collation is SQL_Latin1_General*.

Can I configure the default isolation level for all my SSRS reports.


By default connections to SQL Server are made Read Committed. However in a lot of situation this can result on locking of other users when a big SSRS report is executing. Is there a way to configure my SSRS server that it will connect by default with isolation level Read Uncommited to the database.

At this moment you need to specify the transaction isolation level in every dataset of the report. This will result in problems of somebody forget to specify. By configuring this on server or connection level, you know for sure that all reports are executing with Read Uncommitted.

More information about this topic canbe found on my blog: http://www.keepitsimpleandfast.com/2010/11/bad-performance-and-lockings-occur-ad.html



Will full or differential backup break LSN chain if compatibility level = 80 in SQL Server 2005/2008

My understanding is that full or differential backup will not break LSN chain starting in SQL Server 2005.  However, I'm not sure whether this applies to databases with compatibility level 80 in SQL Server 2005/2008 or not.

Seven reasons to care about SQL Server 2008 R2

Microsoft begins to fully realize its vision of SQL Server as an information platform and not "just" a database. Hence the main theme for this release -- at least according to Microsoft -- is self-service BI. The PowerPivot plug-ins for Excel 2010 and SharePoint 2010 are easily going to make the biggest splash of all the new features, not least because they're the most complete. But then, SQL Server 2008 R2 isn't strictly necessary for PowerPivot for Excel, which works with plenty of other data sources.

sql server 2008 adventureworks database


dear Friends

For my MCTS 70 -433 examination, I recently installed sql server 2008 and installed the sample databases too. but my issue is, in that book they have mentioned a database called "AdventureWorks2008" and the nice thing is I don't have a such a database with me in my sql server 2008. 

And the query is 

-- MERGE Statement
USE AdventureWorks2008
MERGE INTO	Sales.SalesOrderDetailHistory AS SODH
USING Sales.SalesOrderDetail AS SOD
ON SODH.SalesOrderID = SOD.SalesOrderID
AND SODH.SalesOrderDetailID = SOD.SalesOrderDetailID
INSERT (LineTotal, SalesOrderID, SalesOrderDetailID, CarrierTrackingNumber, OrderQty
, ProductID, SpecialOfferID, UnitPrice, UnitPriceDiscount
, rowguid, ModifiedDate, Cancelled)
VALUES(LineTotal, SalesOrderID, SalesOrderDetailID, CarrierTrackingNumber, OrderQty
, ProductID, SpecialOfferID, UnitPrice, UnitPriceDiscount
, rowguid, ModifiedDate, DEFAULT)
UPDATE SET SOHD.Cancelled = 'True'
OUTPUT $action , inserted.* ;	

Please help me to overcome this issue and let me know where can I download that database too.

Thanking you

happy Coding

Word Automation Issue in Windows Server 2008 Hosting



The problem I am posting here is that I was facing nearly 2 weeks around. Any body comes with this stuff please help.

Word Automation in sample ASP.NET(C#) application.

I am using Microsoft.Office.Inetrop.Word Assembly for automation. Here I am reading a XXX.dot template file and fill the contents with dynamic data.

When i am executing my code in localhost:someportnumber the automation is working fine and I could get expected result and when I am hosting in my inetmgr(Windows XP is my OS) it is also working fine.

But the problem is that when I am hosting in my production server(Windows Server 2008 Standard Edition) I am not able to perform automation and results in the following error.

Data: System.Collections.ListDictionaryInternal
Message: Word has encountered a problem.
Source: Microsoft Word

The code gets failed in the following line:

ApplicationClass wordApp = new Microsoft.Office.Interop.Word.ApplicationClass();

Document wordDoc = wordApp.Documents.Add(ref oTemplate, ref oFalse, ref oMissing, ref oMissing); // Error in this line

I cannot able to proceed further. Can anybody please help me in solving this issue?

Thank you.

No ASPNET User in Windows Server 2008?


I have been looking everywhere online regarding this, but have not found a clear answer.


I have an ASP.Net app running on Windows Server 2008, it's basically a reporting app using Crystal Reports. I have encountered a roadblock in regards to rendering some pages. When I run the app in Visual Studio(on the same 2008 machine) everything works perfectly. Yet when I publish it and run it live the reports will not display correctly, I get a message saying Failed to render page.


I looked this error up in the Crystal Reports website and the fixes they have there refer to giving the windows "aspnet" user full access rights to certain folders on the machine. I would be happy to do this, however there is no aspnet user in Windows Server 2008.


I installed the server and set its role to be Web Server. I also checked all the options regarding ASP.Net and IIS 6 compatibility. Yet there is no ASPNET username anywhere.


Did I set the server up wrong? or do I have to do something within ASP.Net to  create this user and then give it rights? 

Not working on Windows Server 2008




I had the CSS friendly adapters working great on our old server (windows server 2003 - 32bit) and now we have moved to a 64 bit environment and now I can not get the CSS friendly adapters to work.

We are using SharePoint 2007.

Is there another work thru for 64bit environment.

I notice windows server 2008 has a directory  C:\Windows\Microsoft.NET\Framework64 would I be using the browser file in this directory???

Please help!

Under the Table: Programming with FileStreams in SQL Server 2008


There's always been disagreement about whether large blobs, such as document and multimedia items, should be stored in the database or file system. In SQL Server 2008 you don't have to choose; filestream storage provides the best of both approaches.

Problem opening dotnet 1.1 projet on 2008 web server


 We recently upgraded to a 2008 development web server and I installed all the stuff to get dot net 1.1 app working on the server.  I can host them and they work.  My problem is that when I try to open one in VS 2003 I get the following error.  I set up the web server the same as my previous one, and I think a long time  ago I got this error when we set up current one but do not remember how to resolve it.  So I moved my project files from the old server to the new server and then I get these errors. 


The web Server reported the following error when attempting to create or open the Web Project located at the following url: Http://localhost:/MobTracker. 'Http/1.1 500 server error
