how to bind treeview in web from table having ParenId relation?
my table structure... Id, Name, ParentID.
I want to show Name as Node Text.
I have an application which has rows of data in a relation database the table needs a status which will always be either Not Submitted, Awaiting Approval, Approved, Rejected Now since these will never change I was trying to decide the best way to implement them I can either think of a Status enum with the values and an int assigned where the int is placed into the status column on the table row.
Or a status table that linked to the table and the user select one of these as the current status.
I can't decide which is the better option as I currently have a enum in place with these values for the approval pages to populate the dropdown etc and setup the sql (as it currently using to Approved and submitted for approval but this is dirty for various reasons and needs changed).
Wondering what your thought on this were and whether I should go for one or the other.
If it makes any difference I am using Entity framework.
how can i select a record from A table and insert into B table using linq?

I have 3 tables (ShoppingCart, Data, Temporary) in database (Entities) I have no problems in getting data into ShoppingCart. I also know how to transfer data from columns in table ShoppingCart into columns of table Temporary (like EngName, CartID, Date, Quantity etc. - see code below) But I do not know how to multiply Quantity in table ShoppingCart by Price stored in table Data and save it into table Temporary. I think the problem is that I do not know, how to select coressponding row in table Data (see "var myCart2" in my code below) which holds the Price value for EngName previously selected by ("var myCart" also visible in the code). protected void Submit(object sender, EventArgse)
{
using (Entities
db = new Entities())
{
try
{
String
cartId = GetShoppingCartId();
var myCart = (from
cc in db.ShoppingCart
where cc.CartID ==
cartId select
cc);
foreach (ShoppingCart
item in
myCart)
{
int
i = 0;
if
(i < 1)
{
string
engname = item.EngName;
var myCart2 = (from

where c.EngName ==

c);

I have two tables in a database and I want to select one value from one of that table. For that I want to pass one value and if that value stored in the table I want pick the id representing the value in the next table.
That means the operation is that first I select a row of data from first table by using a user control in that row there is a value (example "apple") and I want pass that value("apple") to the second table. In the second table the value ("apple") having a id (example "australian") and I want that the query search for that id ("australian") and show that in the text box.
[code]....
Imagine that this is the two tables using a usercontrol I select first a row from first table and I want to pass that value "apple" to second table and find out the id of "australian" (that is equivalent id for apple in the second tabl ) from the second table and show that in a text box.
I am quite new to LINQ, and I am stuck with this probably basic problem, but haven't been able to find a solution, so I thought I could ask here.
So, I have this repository where I put my functions for data accessing, and now I need to write a function to get all the applicants that have applied for this particular advertisement, and their values too. Now, the values are stored in a separate M:N table, where every row consists of the applicantID,advertisementID and value. I just wanna append the value to every applicant that I show, so that it would look like a Ranking List.
However, I do not seem to know how to select just the name column from the Applicant table, and just the Value column from the ApplicantValue table.
And there's this Iqueryable interface that further confuses me...
Here's my function to get the Applicants only:
[Code]....
Now, if I try to add to the definition of the type two columns, it says that it only messes with types, i.e. one type should be passed. So I figured I would do a ViewModel and then pass it, like this
[Code]....
and then in the function I have no idea how to pass the values:

I am trying to find out how to select a row of data from a table, where a column contains a keyword (from a querystring)

View 4 RepliesI would like to know if there is a way I can select a checkbox and this would add an end date to another table? I have 2 tables Staff_Tasks, this has the checkbox set up as an int, 1 or 0, and the other Jobs which has a field end_date. So when the user clicks on a checkbox it will add this end_date as today's date. The end_date is never displayed, its just stored in the database. I am not even sure if this is something that can be done as an SQL query or if it will be done in my back-end code? I am writing in C#. Does anyone have a little more information?

View 2 RepliesI have a Web site live and running now. I am using the Subsonic to handle the database connections etc. I am getting time out expired error while updating a table (say Employee). When I check sp_who2, I see the suspended connection for the PID which is updating with a block by anothor pid, so I run the profiler and found out when ever this suspended connection occur, the blocked pid is a select statement on the view (say ActiveEmployees, which is the same as the table but with some where conditions).

I have a table that stores User messages
Looks Like This:

It Has a FromUserID and ToUserID
Because Employees are Identified through EmployeeID and Customers are identified through CustomerID, I needed to use UserID's so Employees can leave messages for employees and Customers and Customers can leave messages to employees and other Customers 1-2 and 2-1
My Quandry is this, How Do I retrieve the information if the UserID might be a Customer or Might be an Employee, when the UserID could be from one of two tables
ie
How Would I Write?
SELECT wms.FromUserID, ed.FirstName, ed.LastName FROM ed INNER JOIN wms ON wms.FromUserID = ed.UserID
OR SELECT wms.FromUserID, cd.FirstName, cd.LastName FROM cd INNER JOIN wms ON wms.FromUserID = cd.UserID

I have partitioned a table and it has been partitioned according to an account id. ie also rows that have accountid =1 will be in A partition and all rows that have accountid = 2 will be in B partition. so now if i execute a query with where condition accountid =1 sql server will search only in A partition. Suppose if i add another condition to it ie where accountid=1 and place="aaa" will this query search only A partition or the entire table?
View 3 RepliesI need to execute a stored procedure and show the value it returns as a usertype column in a selection list. Eventually this select statment will be converted into a stored procedure, so basically the stored procedure will be called in another stored procedure. I can't quite get the syntax correct.
