Entity Framework - how to join tables without LINQ and with only string?


Hi all,

I have a question about Entity Framework. Please answer if you know answer on this. I have such query :

    String queryRaw =
        "SELECT " +
        "p.ProductName AS ProductName " +
        "FROM ProductEntities.Products AS p " +
        "INNER JOIN CategoryEntities.Categories AS c " +
        "ON p.CategoryID = c.CategoryID ";
    ObjectQuery<DbDataRecord> query = new ObjectQuery<DbDataRecord>(queryRaw, entityContext);
    GridView1.DataSource = query;

Particularly I want to join few tables in one query, but I can NOT use LINQ and can NOT use ObjectQuery with objects mapped to DB fields inside my query. Because each entity creates dynamically. So this is what i can NOT use :



The question is can I use something like this instead of using objects?

query.Join ("INNER JOIN CategoryEntities.Category ON p.CategoryID = c.CategoryID ");

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;

join 3 table in LINQ



i use Default membership provider for my membership

to get data from my database i use  Entity Data Model

now i want to write a Linq to get data from all 3 tables

can you help me to know how to write this guerry



Multiple database support with Entity Framework

One of the features introduced in Entity Framework is being database independent. Which mean each database provider can support Entity Framework by implementing its provider.

This feature allows you build applications independent from the underplaying database provider. In this post I'm going to show how to build an application that support multiple databases using same conceptual model made by Entity Framework.

Data Points: Deny Table Access to the Entity Framework Without Causing a Mutiny


Julie Lerman shows database administrators how to limit access to databases from the Entity Framework by allowing it to work only with views and stored procedures instead of tables-without impacting application code or alienating developers.

LINQ Sorting After Goup w/ Table Reference


Having a little trouble here.  I am taking a table (Articles) and grouping all the results by the key that references another table (ArticleSectionCategories).  I then want to sort these results by the OrderBy field of the referenced table (ArticleSectionCategory.OrderBy).  This is what I am using right now but it is not working.  Any thoughts?


                var GroupedArticles = from A in DC.Articles
                                     where A.PackagesId == packageId
                                     group A by A.ArticleSectionCategoriesId into G
                                     select G.OrderBy(C => C.ArticleSectionCategory.OrderBy);


Entity Data Model and database view returning the same columns as there are in a table


When adding a stored procedure into the Entity Data Model I can select whether the procedure returns a scalar, a (new) complex type or one of the entity types I already defined. 

How do I do something similar for a view?

I mean assuming I have a view like this

CREATE VIEW FilteredFoos as SELECT Foo.* FROM Foo join ... WHERE ...

(that is a view that implements some involved filtering, but returns all columns from one table) how do I add it to the project so that I can use the entity set, but get the Foo objects, not some new FilteredFoo objects.

var foos = myDB.FilteredFoos.Include("Bar").ToList();

foreach (Foo foo in foos) { ...

Thanks, Jenda

Linq to sql does not return appropriate multiple result sets with "If exists" conditions in the stor


Hello All,

I have a stored proc that returns 4 resultsets, they are in the format.

LINQ query with multiple joins, problem


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

VS 2010: no Entity Framework or LINQ support for SQL Server 2000 SQLOLEDB connection?

Hello, I'm working with Visual Studio 2010 and for Data Connections am connecting to a SQL Server 2000 production database. When I try to drag a table to a .dbml file, the Object Relational Designer says, "The selected object(s) use an unsupported data provider."If I try to create an .edmx file via Generate from database, then the alert is, "This server version is not supported. You must have Microsoft SQL Server 2005 or later."So VS 2010 has no support for the Data Entity Framework or LINQ when connecting to a SQL Server 2000 database? If that is the case, what is the best data access strategy for this scenario?
