I have 9 tables i need data out of.. 8 of those tables will always just return 1 row of fields that i need. the 9th table can contain many records.. So what i need is a few fields out of each of the 8 tables and then ALL records from the 9th table.. so i know that because there will be multiple records in the 9th table returned, that the fields i pull from the other 8 tables will contain duplicate information and thats fine since i will be displaying the individual records from table 9 on their own page..So everything could be for the same vendor, except for the date in the 9th table that contains specific dates and details about each record returned.When i review the execution plan im getting an yellow exclamation icon on a nested inner join and has this message as the warning: No Join Predicate
Here is what i have, but is returning incorrectly, way to may records, seems to be stuck in a loop.. then below that, i have one that returns the correct number of records, but everything except one column is duplicate, all the TR columns should be unique in the values stored in them.. the rest should all be duplicates, just because its the same vendor, so all the other information will be generic information about that record.
[Code]....
This FROM and WHERE return the correct number of records, but the fields are all duplicated except the last column with is transaction_date, seems that the 3 TR fields are being populated with the first records data or something.. not sure.
[Code]....

This question is regarding the ASP.NET webservice that i am creating using the DAL-BLL architecture for my final school project.I have a stored procedure, which is a select query with an inner join for 2 tables.Hence the stored procedure returns multi-table value. One of my DAL tableAdapter methods accesses this stored procedure. How do i retrieve the return value in the BLL? Do i have to create a class structure similar to the one supposed to be returned by the stored proc? or is there a direct way to achieve the same?
Here is some more information:I am using the SQL dataset (.xsd) in DAL. So i have a datatable called "Insurance", which has a tableAdapter. One of the queries in the adapter references to a stored procedure, which has an inner join. So my SP looks like:
ALTER PROCEDURE dbo.GetInsurancesPaged
(
@startRowIndex int,

I am new to MVC and am trying to join 2 SQL tables together and return them in a Json. One table is OutreachProgram. The other table is UserInfo. I want to return the rows from the OutreachProgram table that match on CenterID with the UserInfo table.
The code that exists now will pull all rows from the OutreachProgram table. I can't figure out how to add the UserInfo table to the query to make it work.
JsonGrid <OutreachProgram> grid =
new
JsonGrid<OutreachProgram>(db.OutreachProgram,
new
OutreachProgramFilter());
public Array GetItems(IQueryable<OutreachProgram>
source)
{ return (from r
in source.AsEnumerable()
select
new {
ID = r.OutreachProgramID, CenterID = r.CenterID, DateOutreachProvided = r.DateOutreachProvided.ToShortDateString(),
NameOfProvider = r.NameofProvider.ToString(),
}).ToArray();
}

I am having trouble with duplicate records. I tested .distinct() in several areas and nothing helps.
I got the search criteria from the PreviousPage. I then used this criteria to search QueryA.
I did a search using QueryA. I took the results, and put the IDs into an array.
I then did a search using QueryB, that matched the IDs in the array. QueryB is used for the ListView and to page records.
Using test records. QueryA results = 2 records. The array.length = 2. QueryB results = 3. ?
What am I doing wrong ?
Some of my Code:
myResults = (from r in QueryA
select r.ID).Distinct().ToArray();
totalrecords = myResults.Length; // = 2
using (ToHealthEN n = new ToHealthEN())
{

I want to get data from Projects(which have CourseId) and related CourseName from Courses table.
I have written following code:
var projects = from n in db.Projects
join c in db.Courses on n.CourseId equals c.ID
orderby n.Name
select new { Project = n, Course = c };
return View(projects.ToList());
and I get error:
The model item passed into the dictionary is of type 'System.Collections.Generic.List1[<>f__AnonymousType22[ProjectManager.Models.Project,ProjectManager.Models.Course]]', but this dictionary requires a model item of type 'System.Collections.Generic.IEnumerable`1[ProjectManager.Models.Project]'.
What I need to do in Controller and in View to display this data?

I want to be able to do a join query between my two tables Accounts and BankTransactions. This is a one to many relationship, there can be multiple BankTransactions per Account. I want to query this and display the account information including all the bank statements that are associated with it. I did a join in order to get it, but I am having trouble handling the model. I keep getting this error:
LINQ to Entities does not recognize the method 'System.Collections.Generic.List1[MatchGaming.Models.BankTransaction] ToList[BankTransaction](System.Collections.Generic.IEnumerable1[MatchGaming.Models.BankTransaction])' method, and this method cannot be translated into a store expression.

I know I'm missing something here but I can't figure out what it is. I've got a query joining three tables....accounts, payments, and a table linking the two (there is a M:M relationship).I'm trying to pull a list of all accounts in the account table that have a payment that needs to be resequenced, and also the maximum payment priority if there are any payments that haven't been fully paid. If all payments HAVE been fully paid, I want to return a 0.
It's that last bit of logic that I can't get right. If I include that in the where clause, I get only the accounts that have a payment that hasn't been fully paid. If I take it out, I get all the accounts I get, but I get the highest payment priority whether or not the payment has been fully met.
Here is the query....how do I include the where clause criteria but still include all accounts?
select distinct
bat.acct_id,
isnull(max(isnull(crt.pymt_priority, 0)), 0)[code].....

To write a join query with or condition. It means a query has two inner join, here it is possible to fetch the records, if one inner join is true and other is false. I got a record when only two join conditions are true.

I need to write a webservice that returns multiple rows from a table. I am familiar with return of a single object.
I am calling a stored procedure in the webservice that populates a data table.
I guess I need to define an object collection to be returned. Should this be an array or can I return the data table itself?

I have an update function in my data layer which is defined as:
public int UpdateRBTable(parameters ...) This calls a SQL Server Stored Procedure to perform an update function on the database.
The process does its job for updating the table. However, the stored procedure has a return value (which indicates how many rows were updated), but this return value is not returned to the application. The application always shows that a zero was returned from the stored procedure.

The website is over half way done and the functionality for the blog is (except for adding posts) is already implemented and working correctlyI have a SQLExpress 2008 backendBlog posts are rendered on the page with full HTML markup within a label control.
All of the above is done and working. Though I am essentially new to creating websites with ASP.NET, CSS and SQL, I am sure that I could simply carry on and make a login page with some controls that would allow me to add records (blog posts) directly to the database on the host server. However, I am fearful of doing this because I know that malicious code can be passed in this way. Also, because of my lack of knowledge, the only way that I know of to pass the code from a control to the database is to disable validation for the page the control is on. Without a doubt I do not want to do that.
So what are my options for getting blog posts into the database? Is it safest for me to fully create the post in html and update a copy of the database that resides on my local machine? If I do it this way, how can I merge the records from the database on the local machine with the records on the remote server?

In the procedure function, there will be queying several times based on conditions.
Suppose each query retrieves several records, can I caumulate those records in on table, then return that table.
Benifit I want to success here is that I want to save time, so instead of making several functions each has one query, each one requires a connection to databae, so it will take time.
