SQLXML 4 - How to specify a relationship on repeating element of global complex type

Posted By:      Posted Date: May 22, 2011    Points: 0   Category :

I have tried to create a sample showing the issue.  Basically we have multiple elements that use a global complex type.  This complex type has a repeating element and, therefore, should have another relationship specified for it.  I've tried specifying two relationships on the "Phone" element that reference their respective parents, but that does not work.  Is this scenario supported in SQLXML using SchemaGen?

<?xml version="1.0" encoding="utf-16"?>
<xs:schema version="1.0" xmlns:xs

Parent-Child relationship on a Type 2 (SCD) Dimension

For a Type 2 slowly changing dimension (SCD) such as Employee with a Parent-Child relationship, how do you handle the explosion of new rows when a high ranking employee has an attribute change?   It will require terminating the high ranking employee row and adding a new current row with a new surrogate key. Then every employee row below this employee will also have to be terminated and a new current row added with the new surrogate key of the parent.   This will have to be performed 1 level at a time so the subordinate rows will have the new surrogate key of their immediate parent.   For a large organization such as 20,000 employees, this will result in a dimension with hundreds of thousands rows in a relatively short time.   Is there a better way to model this?

'Frame' TargetType does not match type of element 'PlaceHolderControl'

Hi. I'm trying to modify ControlTemplate for WPF Frame control. I extract Frame ControlTemplate  using blend. When I try to compile my app I get the following error: 'Frame' TargetType does not match type of element 'PlaceHolderControl'. Any ideas why?

External Content Type - Read List Operation - "Cannot find a collection element of a supported type.


I'm trying to define External Content Type Operations for an External Content Type. I can add a Connection, Type "WCF Service" no problem. And I can define a "New Read Item Operation" using that connection.

But I can't define a "Read List Operation". I get the following error message, in the Return Parameter Configuration: "Cannot find a collection element of a supported type..." it goes on to say - see the help documentation for supported types. I can't find any help documentation on this.

I've tried returning different types in the provider web service but keep getting the same error. What are the supported types the web service can return?

The reading I've done suggests that you can connect to a non-MS web service using a connection type of "WCF Service". Is this correct? If it is what's the best soap format the web service provider should use - Doc/Literal?



Circular Reference with Complex Type


I have created a webservice that returns a complex type.  This is the xml that is returned from the webservice:

<NinjaRouteEntity xmlns="http://tempuri.org/">
  <Entity NinjaRouteID="1" xmlns="">
    <EntityCollectionReference PropertyName="PointCollectionViaNinjaRouteVector">
        <Entities />

MessageContract/XMLSerializer - Known Type not being named with its element name when passed as obje


Okay, I've just deleted my first post since I was having issues with editting a post with codeblocks.  Trying once more.

I'm new to WCF and I am trying to write a webservice that must follow a specific XML format.  Because of this, I found that I had to drop DataContractSerializer since I must be able to use attributes.  I now have the <XMLSerializerFormat> attribute on my servicecontract for this purpose and I have laid out the schema I need by using a Class with Public Properties and the <Serializable()> attribute where appropriate.  I have one service endpoint that has several different schemas that it may accept.  I have a base class with derived classes for this purpose.  This also works well from what I can see as the test client and webservice are talking to each other just fine.  However, the client that will be using the service is non-WCF and must have the elements named specifically in order to handle them.  The problem arises when the service is serializing the derived classes.  The structure of each class works perfectly, however, the name of the element is not the name of the element I have assigned it.  It is most likely because of the way that I pass the information back and forth to the service and the fact that I do not know what the object actually is when it is passed into or out o

'Window' not type of element 'WindowInstance' Error


I've been teaching myself WPF for about a week now, so I'm sure this is something easy.
I have made a project to contain my 'Themes' for a window.  Assembly= libThemes   Namespace= Theme_Library

casting to complex type


I'm trying to figure out how to use the combobox item object collection.  Given the code below, how can I put a term in the "Cast<?>" statement to get my anonymous types back?  Or, is there a completely different way to do it?  Can I explicitly cast 'a'?

var citiesbox = new ComboBox();
ComboBox.ObjectCollection objects_to_store = new ComboBox.ObjectCollection(citiesbox);
objects_to_store.Add(new { cityid = 1, cityname = "Eugene" });
objects_to_store.Add(new { cityid = 2, cityname = "Portland" });
objects_to_store.Add(new { cityid = 3, cityname = "Salem" });

var citycode_from_db = 2;

citiesbox.SelectedItem = from a in citiesbox.Items.Cast<?>
             where a.cityid = citycode_from_db
             select a;

Complex Matrix column data with different data type

I have a data like this

drop table #table
select 34 as A,17948 as B,0.19 as C,19 as D,16145 as E,'Jan' as Period into #table
Insert into #table
select 26 as A,14206 as B,0.18 as C,19 as D,13411 as E,'Feb' as Period
union all
select 38 as A,13037 as B,0.21 as C,18 as D,14974 as E,'Mar' as Period
select * from #table

From this #table i want the view as below format and is doable thru matrix report option in SSRS,but the problem i am running is that i cannot get in this type of data type format. If you look into it,i have column with header 'Jan' and it has data in different data type e.g money,number,percentage. I need to maintain this data type in order to do the calculation after it generates the report on excel spreadsheet. If i use the varchar for the column, it is not usable to me in the final report and i cannot do the calcualtion. Any workaround will be highly appreciated.

Using Complex Type with Stored Procedure in EF4.0??


Hi All,

Playing with my new toy, VS2010.

  1. Created a .NET 4.0 Web App.
  2. Added Entity Data Model, SPTestModel.edmx, using local AdventureWork SQL Server database, included all tables and one stored procedure.
  3. From the Model Browser>Add Function Import>Choose Stored Proc>Get Column Info>Create New Complex Type>Return a Collection of New Complex Type>OK
  4. Add new WFC Data Service
    1. namespace SPTestDataService
          public class SPTestDataService : DataService<SPTest.AdventureWorksEntities>
              // This method is called only once to initialize service-wide policies.
              public static void InitializeService(DataServiceConfiguration config)
                  config.SetEntitySetAccessRule("*", EntitySetRights.AllRead);
                  config.DataServiceBehavior.MaxProtocolVersion = DataServiceProtocolVersion.V2;

QUESTION: How do I use the stored procedure?? The complex type mapped to it is ju

DataAnnotation with .edmx complex type


I have a problem.

In edmx Contact entity PersonalInfo complex type is defined with property FullName and Title.

In view the code is

<div class="editor-label">
                <%: Html.LabelFor(model => model.PersonalInfo.FullName) %>
            <div class="editor-field">
                <%: Html.TextBoxFor(model => model.PersonalInfo.FullName) %>
                <%: Html.ValidationMessageFor(model => model.PersonalInfo.FullName) %>

Got buddy class like
    public partial class Contact

    public class ContactValidation

        public string FullName { get; set; }

When I submit form get an error of mapping but if I take FullName out of complex type than form is working fine.
How I validate FullName if it is in Complex type?

An Entity Relationship Diagram Example

An Entity Relationship Diagram conveys a lot of information with a very concise notation. The important part to keep in mind is to limit what you're reading using the following technique:

Choose two entities (e.g. Company and Employee)
Pick one that you're interested in (e.g. how a single Company relates to employees)
Read the notation on the second entity (e.g. the crow's feet with the O above it next to the Employee entity).

TreeSelector : playing with generics and type inference

create a generic way to define a selection starting from a tree of objects, the most simpler way as possible.

Let's start with the beginning...
Here is a very simple little interface defining a node of the tree, basically, a value and the references to the child nodes.
