problem with [SqlException (0x80131904): Invalid object name 'dbo.TableName'.]

Question

I was looking in google and stackoverflow and i did not find the answer, how can I connect to my database table through that connection string in VS 2010 ?

<add 
  name="ArticleDBContext" 
  connectionString="Data Source=mssql3.webio.pl,2401;Initial Catalog=db_name;Persist Security Info=True;User ID=db_user;Password=passwd;Pooling=False"
  providerName="System.Data.SqlClient"
 />

I always get error: problem with [SqlException (0x80131904): Invalid object name 'dbo.TableName'.]

I know that 'dbo' is SCHEMA , i don't need it, how can I change that ?

i use mvc and EntityFramework

and the code is like this:

in models :

public class Article
{
    public int ID { get; set; }
    public string Title { get; set; }
    public DateTime CreateDate { get; set; }
    public string tekst { get; set; }
}

public class ArticleDBContext : DbContext
{
    public DbSet<Article> Articles { get; set; }
}

and in controller :

public ViewResult Index()
    {
        return View(db.Articles.ToList());
    }

the example is taken from http://www.asp.net/mvc/tutorials/getting-started-with-mvc3-part4-cs

Solution

i found that answer and it helped !

MSSQL: Change tables owner to dbo with sp_changeobjectowner

Sometimes there is a need to change all tables in the database to be owned by dbo for maintenance or to fix up accidental errors. All tables owned by dbo schema is usually best practices in the database application development with MSSQL while we can meet different approaches in real life...

The following small SQL code snippet goes through all user tables in the database and changes their owner to dbo. It uses sp_changeobjectowner system stored procedure:

DECLARE tabcurs CURSOR
FOR
SELECT 'SOMEOWNER.' + [name]
  FROM sysobjects
 WHERE xtype = 'u'

OPEN tabcurs
DECLARE @tname NVARCHAR(517)
FETCH NEXT FROM tabcurs INTO @tname

WHILE @@fetch_status = 0
BEGIN

EXEC sp_changeobjectowner @tname, 'dbo'

FETCH NEXT FROM tabcurs INTO @tname
END
CLOSE tabcurs
DEALLOCATE tabcurs
