• Accessing System Databases/Tables using LINQ to SQL? 2 answers

I'm trying to write an application which I can point at different databases and look at the database's schema, that is, tables and their column's properties, relationships, constraints, etc. I've been looking into the LINQ to SQL method GetTable(), but this appears to return nothing;

1. To update a row in the database. Query the database for the row to be updated. Make desired changes to member values in the resulting LINQ to SQL object. Submit the changes to the database. The following example queries the database for order #11000, and then changes the values of ShipName and ShipVia in the resulting Order object.
2. In LINQ to SQL, the data model of a relational database is mapped to an object model expressed in the programming language of the developer. When the application runs, LINQ to SQL translates the language-integrated queries in the object model into SQL and sends them to the database for execution.
3. I am trying to update a the database via Linq-to-SQL. I have a table named Staff_Time_TBL which has 9 columns. I am trying to update a single columns record on potentially multiple rows. My LINQ query is as follows. It grabs data from column Section_Datafrom a specified date to another specified date and from a single employees Number.
4. It will work if you have a timestamp in that table. The problem here - the update query will be bloated (all columns will be set) and by working in disconnected mode - you lose the advantages of LINQ (deferred loading) and stay with an object representation of a table.

What am I doing wrong!?

In SQL, I would do this: UPDATE dbo.Person SET is_default = 0 WHERE person_id = 5 Is there a way to do this in LINQ? Update records using LINQ. LINQ query on.

var model = new AttributeMappingSource().GetModel(typeof({YourDataContext})); return model.GetTables().ToList();

Edit to my original solution:

The problem is that you don't have entities SchemaDataContext, so there are no mappings at all. But if you don't have entities in SchemaDataContext anyway, you really shouldn't use an ORM.

Here is a simpler solution, without Linq to SQL:
