Types in Yukon: Managed UDTs Let You Extend the SQL Server Type System

Posted By:      Posted Date: August 21, 2010    Points: 0   Category :ASP.Net

The next version of SQL Server, code-named "Yukon," will offer enhanced support for user-defined types (UDTs). Because UDTs can be managed by the CLR, you can represent a wide variety of data structures to create types not possible with previous versions of SQL Server. With UDTs you can more precisely control the kind of data your type accepts, resulting in better data management. This article explores UDTs in "Yukon" and covers their design and implementation.

Error Handling: Throwing Custom Exception Types from a Managed COM+ Server Application


Exception handling semantics in .NET are based on type, so you can create custom exceptions that have their own properties and methods. In .NET, exceptions are first-class citizens, and since they're the built-in error handling mechanism, all .NET-compliant languages must support exceptions. In addition, COM+ services are available to .NET code as Enterprise Services, so you can leverage exceptions in your Enterprise Services design.In this article the author describes custom exceptions, throwing exceptions across COM interop boundaries, and working with Enterprise Services.

No mapping exists from object type System.Web.UI.WebControls.Label to a known managed provider nativ

 I'm making the leap to move from vb.net to C#, and I'm getting this crazy error when I try to execute one sp, set a value, and then execute another sp based on the value.   Any suggestions??? proc_GetSectionDetails is my first stored procedure.  From that, I get a value for SectionID, and then use it for the second sp called  proc_GetSectionDetails protected void getSectionContent() { SqlConnection conn = default(SqlConnection); SqlCommand comm = default(SqlCommand); SqlDataReader reader = default(SqlDataReader); string connectionString = ConfigurationManager.ConnectionStrings["123"].ConnectionString; conn = new SqlConnection(connectionString); comm = new SqlCommand(); comm.Connection = conn; comm.CommandType = System.Data.CommandType.StoredProcedure; comm.CommandText = "proc_GetSectionDetails"; comm.Parameters.AddWithValue("SubSectionID", Request.QueryString["SubSectionID"]); conn.Open(); reader = comm.ExecuteReader(); if (reader.Read()) { lblName.Text = Convert.ToString(reader["SubSectionName"]); lblDesc.Text = Convert.ToString(reader["SubSectionDescription"]); Label SubSectionParentID = new Label();

No mapping exists from object type System.Xml.Linq.XDocument to a known managed provider native type



I am using XML in getting client data in 3-tier architecture, using XDocument in passing XML among layers.

But when I use it in inserting this XML in XDocument, it throws the following error:

No mapping exists from object type System.Xml.Linq.XDocument to a known managed provider native type. 

I am using the following code, it throws the exception at the bold line:

System.Security.SecurityException: Request for the permission of type 'System.Web.AspNetHostingPerm


Good Day all,

Having an issue with an outside user accessing my IIS7 box. I do not have this problem when running the website from my host machine. I found this post: Http://forums.asp.net/t/1371394.aspx. I assure you that this is not a solution because I am not storing any of my files on a network share. 

What do you think my approach should be. 

I already have read rights to IIS user to my BIN folder. 

Thanks for the help.

The type 'System.Data.Linq.DataContext' is defined in an assembly that is not referenced. You must



This is frustrating, and I don't know how to solve it.

I have a strange problem. I am adding a LinqDatasource object, and set the context:

        protected void LinqDataSource_ContextCreating(object sender, LinqDataSourceContextEventArgs e)
            e.ObjectInstance = new KaruselaDataContext(ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString);

Then I get this error:
The type 'System.Data.Linq.DataContext' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Data.Linq, Version=, Culture=neutral, PublicKeyToken=b77a5c561934e089'.


On web.config I already have this:
<add assembly="System.Data.Linq, Version=, Culture=neutral, PublicKeyToken=b77a5c561934e089"/>

NOTE: The datacontext is in a different project (DLL proect) where I added a refernce to System.Data.Linq.

is there another way adding a refernce to a web project? or only though teh web.config?

XML in Yukon: New Version Showcases Native XML Type and Advanced Data Handling


The next version of Microsoft SQL Server, code-named "Yukon," represents quite a few steps forward in the evolution of XML integration. Yukon supports native storage of XML data using the XML data type, which makes it possible to run native queries on XML data using the emerging industry standard XQuery language. Data integrity of the XML data type can be enforced through schema validation and XML-based check constraints, and special indexes can be defined that help speed up queries. In addition, Yukon has the built-in ability to expose its data through Web services. This article discusses these and other XML features of Yukon.

T-SQL in Yukon: Powerful New T-SQL Syntax Gives SQL Server a Programmability Boost


The T-SQL language in the upcoming version of SQL Server will provide more power and flexibility than previous versions. Additions and enhancements include error handling with the TRY/CATCH construct, SNAPSHOT isolation, and WAITFOR enhancements. Also important are the BULK rowset provider, common table expressions, recursive queries, PIVOT and UNPIVOT operators, and much more. This article introduces these features so readers will be ready for the next version of SQL Server.
