LINQ query with multiple joins, problem

Posted By:      Posted Date: August 27, 2010    Points: 0   Category :ASP.Net

I am using a LINQ query with multiple joins, the last join does not return any values even though values exist in the database. Below is my code.

when the query returns suiteNameTrg and SuiteTypeTrg are empty, all other values are returned correctly.

string suiteNameTrg = string.Empty;
            string suiteTypeTrg = string.Empty;
            using (DataClassesDataContext db = new DataClassesDataContext())
                    var productQuery = from assets in db.ASSETs
                    join relocatableUnits in db.RELOCATABLE_UNITs on assets.RUID equals relocatableUnits.RUID into assets_units
                    from relocatableUnits in assets_units.DefaultIfEmpty()
                   join build in db.BUILDINGs on assets.BUILDING_ID equals build.BUILDING_ID into assets_bins
                   from build in assets_bins.DefaultIfEmpty()
                   join test in db.TEST_SUITEs on assets.TEST_SUITE_ID equals test.TEST_SUITE_ID into test_bins
                   from test in test_bins.DefaultIfEmpty()
                    join testTrgt in db.TEST_SUITEs on assets.TARGET_TEST_SUITE_ID equals testTrgt.TEST_SUITE_ID into testTrgt_bins
                    from testTrgt in testTrgt_bins.DefaultIfEmpty()

                    select new

Is there a way to query entity based on multiple filter criteria? WCF Data Services, Linq to Entiti


Instead of:

DW_CMSOPEN dwc = new DW_CMSOPEN(new Uri("http://acctdev02/WCFDataService/EmployeeService.svc"));

dwc.Credentials = System.Net.CredentialCache.DefaultCredentials;

var employees = from emp in dwc.Employees 
             where emp.DEPT == "123"
             select emp;

I'd like the linq query to resemble:

var employees = from emp in dwc.Employees
              where emp.DEPT // in {"123", "456", etc}
              select emp;

SQL Query Multiple rows Top problem.

This is a simplified example of my problem.
I have a Product table, and a ProductSupplier table.  A Product can have multiple Suppliers; these suppliers are ordered according to a sort order field and each has an associated price for the Product.

I want to run a query to return all my products, along with their first supplier and the cost against this supplier.

Currently the only way I can do this is by performing select statements in the manin select clause to retrieve the supplier information.

Help with SQL query to Linq (VB.Net)



I am facing problems converting a relatively complex SQL query to a LinqToSQL statement. There are lots of examples on the web, but none involve 'joins' + 'where' + 'group'

Here is my query I am trying to use Linq for :

select Customers.CustomerID,          
       count(*) as NumOfOrders,         
       sum(Customers.BillingAmount) as BillingAmount,      
       sum(Orders.OrderTotal) as OrderTotal  
From Customers 
left outer join Orders on Customers.CustomerID = Orders.CustomerID
Where Customers.Name = @username	  
      and Customers.LastLoggedIn > @fromdate	  
      and Customers.LastLoggedIn < @throughdate	  
      and Customers.ZipCode = @zipcode 
group by Customers.CustomerID

I need help converting this to a LinqToSql for VB.Net

Thank you very much!

Multiple Submit Connection Problem


Hello everyone,

I have an InfoPath form with two Submit Connections. One of them is a regular submit connection to a SharePoint Document Library. The other is a submit connection to the UpdateListItems web Service.

I have one button using rules that submits the forms fields to the Document Library. Some of those fields have data validation rules like entry must be four digits, and field cannot be blank.

The other submit button uses rules to submit an XML template to the UpdateListItems Template. My problem is that even though this second button does not have the first submit connection as an action, the form will still check all of the forms fields to see if they violate the validation rules before it will submit to the Web Service.

How do I tell InfoPath to ignore the validation rules when I only want to submit to the Web Service? I want the user to be able to enter data into the XML template fields and submit to the Web Service, even if some of the rest of the fields are blank. Right now if any of the other fields fail validation it prevents submittal to the web service even if the fields that failed validation are not being submitted to the web service.

Thanks for any advice that can be offered,
Bill Hurt
