I'd like to create an XML file(based on the above tables mentioned) which I'd like to bind to a treeview control, but I'm not sure how to do that.

i have a form view that takes fields from two tables 'Contract' and 'volunteers', however because i used a query builder,i have to input an insert statement. How do i create an insert statement for two tables in one query?
View 4 RepliesI have a table that contains item data. If the item is a particular type further information exists to describe the item. The additional information isn't that heavy however the number of records in relation to the main file will be quite small (less than
5%).
So I have 2 scenarios:1) Put the additional data in the main table and take tha hit on storage
2) Create an additional table and link the 2 together
If we were talking huge amounts of data I can understand that 2) would be the obvious choice but given the simplicity should 1) be a consideration?
If 2) is the answer - is it possible to create a dependency between the 2 tables when the item is 'that' particular type. In other words wnsure the addition data is populated for the required items and not others.
I have a set of keywords (about 1000 keywords), and I want to build a wide table, up to 1000 columns:
+each column corresponding to a keyword
+each row will represent an article document, which each cell will be the frequency of the keyword in the document
How to do that in a programmatically way? (e.g., using Linq and C#)
I do have a details view, which insert data to a database table using SQL Datasource. Now i need the data to be inserted in to 2 tables instead of one.
View 1 RepliesI am using Entity Frameowrk as the ORM. I am new to MVC and trying to develop a samll module as a learning project.
Now I am stuck with an issue for which I can't seem to find out answer on web. The issue is :
I have two tables mapped as entities - Tenant_Definition and Contact
Tenant_Definition { Tenant_ID , Desc, Contact_ID}
Contact {Contact_ID, Company_Name,Company_Address,Person_Name, Person_Phone_Mobile}
My View has to present a form that shows Tenant Desc and Contact related fields. The index view works fine and shows the desired values.
But, the create view isn't working out. In the create view, i am planning to do -
1. creating a new contact entity instance and saving it in db
2. Then creating a new tenant entity instance using the new contact_id and save it to the DB.
However, the code doesn't seem to be inserting any value inside Contacts table. It inserts null value.Below is the code snippet of my Create Controller -
[HttpPost]
public ActionResult Create(FormCollection collection)
{
var newContact = new Contact();[code]....
I have an entity object as model input in my view. Not sure if it's the best approach, but I use the object references to get values from a related object.Let's say I've got a car entity and a manufacturer entity.Here's how it would look in my view
[Code]....
I've get a nullreferenceexception where the car entitity does not have a reference towards manufacturer. I'd like to output a " " if no manufacturer exists.
Is there a way to create the required Membership tables/SPs for Oracle? Just what aspnet_regsql does. Something like aspnet_regORACLE :).

View 9 RepliesWe are working in a new N-Layered application with EF4 as ORM. As a requirement, we need to give support for both SQL Server and Oracle existing databases.
Our wish was to build a single EDMX model and then generate our business entities from a TT file.
The main problem was that database providers may generate different .NET types from our database field types. In this case, we'll have different EDMX models and then different auto-generated entities, which is more or less the same as have two different applications.
I don't know if we could have different SSDL files with specific database information (one for Oracle and another one for SQL Server) in separete files and share CDSL and MSL information for both databases.
Would be this solution possible?
Someone knows some other way to work with Oracle and SQL Server using EF4?

Error i am facing is :
Msg 8668, Level 16, State 0, Line 2
Cannot create the clustered index 'RateViewIndex' on view 'NoteToPass.dbo.RateView' because the select list of the view contains an expression on result of aggregate function or grouping column. Consider removing expression on result of aggregate function or grouping column from select list.
May I know in SQL Server, what is the similar syntax for %TYPE in Oracle, i.e. the variable defined will follow the data type defined in the database column?
View 3 RepliesI am using Reporting Services to render a report directly to PDF. It requires that I use two web references: ReportExecution2005.asmx and ReportService2005.asmx. The performance on web references seems really poor. Since my web server (IIS7) and my SQL Server (2008) are on the same box, is there a way I can reference them directly? If not is there any way I can explicitly cache them or something. First load is really really slow, second load is perfectly acceptable.
View 2 RepliesI have a website in which code on the production server runs no problem. The same code on my local machine or test server produces the mess seen at the end. The exact same code. Additionally, upon trying to preview any of the table adapters in the dataset I get "DataSet1.thename could not be previewed. The provider is not compatible with the version of Oracle client"
The app is SQL Server. It always has been. It has never used Oracle. Does anyone have any insight on how to fix this? As it is now I can't do anything with my dataset. I can't edit anything in there because of this complaint about Oracle.

View 4 RepliesI have an user control placed on a content page. The content correctly receives the session variables. In the user control I have the following
1. The pageload fires and the text box is correctly set.
<script runat="server">
protected void Page_Load(object sender, EventArgs e)
{
if (Session["app_id"] != null)
{
txtAppId.Text = Session["app_id"].ToString();
}
</script>
2. I have datagrid in the usercontrol which has a binding variable tied to a control parameters as follows
<asp:SqlDataSource ID="SqlDataSourceMain" runat="server"
ConnectionString="Myconnectionstring"
ProviderName="MyProvider" SelectCommand="select
last_name,first_name
from applications
where (id = to_number(:pAppId))">
<SelectParameters>
<asp:controlparameter name="pAppId" controlid="txtAppId" propertyname="Text" />
</SelectParameters>
<SelectParameters>
<asp:controlparameter name="pAppId" controlID="txtAppId" propertyname="Text"
Direction="InputOutput" Type="Int32" ConvertEmptyStringToNull="True" />
I tried the following, same error
</SelectParameters>
<asp:SessionParameter
ConvertEmptyStringToNull="True"
DefaultValue="0"
Direction=" InputOutput "
Name="pAppId"
SessionField="app_id"
Size="integer"
Type="String" />
</asp:SqlDataSource>
For some reason the select parameter pAddId is getting set to null and get the following error when the content page is loaded If I hard code the value it works RA-01036: illegal variable name/number Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
