DataSource Controls :: How To Return A Single Row Where There Is A One To Many Relationship
Jun 23, 2010
I have 2 tables. Table_A has one to many relationship with Table_B.
For example. Table_A has an ApplicantKey and in Table_B I am storing (Resume_name and CoverLetter_name for the Applicant). Joined by ApplicantKey
Now when I join them and execute the query obviously it returns me two rows. But what I want is that it should return only one row with Columns like Resume_name, CoverLetter_Name

A co-worker of mine just came back from a SQL Server Reporting Services class (we are using SQL Server 2005). In that class they were told that if they had a one to many relationship that they would have to flatten the results into one row of the resultset in order to show the 'many' portion of the relationship. For example, my company has two tables:Jobs Notes/Memo'sor each Job we can have 0 or more Notes/Memo's.According to my co-worker the Report Server must have each of the Notes/Memo's in one row of the resultset. That we therefore have to flatten the list of Notes into Note1, Note2, Note3...etc fields.Is this correct? How would I handle a situation where I didn't know how many Notes there were?

I need to know if I've done something wrong, or if the message I'm getting is nothing about which to be alarmed.I'm getting "The relationship '....' has columns that are not part of the key of the table on the primary side of the relation ship which is not supported, the relationship was excluded.
I built four tables, each with one foreign key. I'm assuming I haven't done anything wrong or unusual with my four tables (SQL statements generating the tables are shown below).However, I don't get any lines connecting tables together and all the examples I've seen today seem to have no problem with drawing the connecting lines all over the place.

For context: First of all, I am new to LINQ, as I have been using SubSonic for quite some time now.
I have two tables, Users, and Affiliates. They both have a very typical schema. The FK that joins them is the UserId field, which is in the Affiliates table. I want to create a LINQ query that pulls the Username from the Users table using the AffiliateId value. The AffiliateId is a primary key of the Affiliates table.
I have tried to accomplish this using many variations of the following code:
[Code]....
In the above query, I expect to get a single row result set. However, I instead receive the entire table of results.
How can I make this work? I have yet to see an example or article out there to do what I am trying to do.

I have 3 tables User, role and UserInRole THe entity frame work made entities for User and Role and I have successfully made a join with the user and role entities using user.add(role); but I can't seem to get it to remove the link (I want to retain the user and role just remove their association).
using (ProviderEntities context = new ProviderEntities())
{
User u = context.User
.Where(n => n.ApplicationName == application)
.Where(n => n.Username == username).First();
Roles r = context.Roles
.Where(n => n.ApplicationName == application)
.Where(n => n.RoleName == roleName)
.First();
r.User.Remove(u);
context.SaveChanges();
}
The oposite worked when I did r.User.Add(u); but it wont let me now remove it after it been created. Driving me mad as I can't see where I have gone wrong.

I still have plenty to learn about SQL... I'm pretty sure what I want to do is possible, but I'm getting lost in the syntax.
I have two tables:
TABLE A: [ID] [Name]
TABLE B: [ID] [TableA.ID] [intValue] [intTypeID]
There are 3 pieces of information I want:
Total Sum(TableB.intValue)
Sum(TableB.intValue) WHERE intTypeID = 1
Sum(TableB.intValue) WHERE intTypeID = 2
Getting one of those pieces is simple: SELECT a.ID,a.Name,SUM(b.intValue) WHERE a.ID = x GROUP BY a.ID,a.Name
I assume I need some kind of JOIN, but I can't seem to get it..

I have a products table whereby I want to return a single row via a product id and use it as a data object.
I have used a .xsd dataset and a product class where I return a dataset and add the values into the product object that I created but I don't like having to write code like
"Product[0].ProductDescription" to get the product description. Is there a way of returning is straight as an object rather than a dataset?

a FormView that is linked to SqlDataSource1a Repeater control (inside the formview) that is linked to SqlDataSource2 Thus representing a simple "1 to many" or "parent/child" relationship in the database!
SqlDataSource1 is simple in that it just retrieves a straight set of records from a table and they are displayed back in the FormView (nothing special happening there).
SqlDataSource2 has parameters that filter the contents of the repeater based on the record that is shown in the Formview. This would normally be simple enough to set up by setting the parameter to the formview.selectedvalue property.
HOWEVER - THE PROBLEM ARISES...
The formview has multiple DataKeyNames because the table that the SqlDataSource1 links to has a compound key. So to filter the Repeater correctly SqlDataSource2 needs to map 3 parameters to 3 data key values in the formview.
I've tried setting the SqlDataSource2 parameters to:
<SelectParameters>
<asp:ControlParameter ControlID="FormView1" Name="Parameter1" PropertyName="DataKey(0)" />
<asp:ControlParameter ControlID="FormView1" Name="Parameter2" PropertyName="DataKey(1)" />
<asp:ControlParameter ControlID="FormView1" Name="Parameter3" PropertyName="DataKey(2)" />
</SelectParameters>
but it doesn't seem to like that approach. I'm expecting the answer is something similar .

i develop a c# windows application. My database is sql server 2008 exp. i want lock single row for user select it for update. for example;
userA - Connection a (connection id 52);
user select a single row (select * from t1 with(rowlock?, updlock?,or what) where id=1) and bind data to form fields (texbox, checkbox,combobox etc.). (there is no problem)
userB - Connection b (connection id 54);
userB can select all other rows from t1 (where id=2 or 3 or anything) but not id=1. when userB select * from t1 where id=1 system generate an exception with (you cannot select this row because it is updated. Updated users connection id is 52.)
when userA (connectionid52) close form or commit changes then userB can select id=1.
i am read few documents (transacions, rowlock,updlock, concurrency violation optimistic,pessimistic) but i couldn't understand.
