View 1 RepliesI have MyDB.dbml in my Models folder that was created by dragging tables from Server Explorer. I'd like to make some changes to the design of those tables. Before I do that, how do I get the dbml to refresh itself?
I do expect to have to fix code where field definitions change & that's okay. I just don't want to have to start over from scratch.

View 3 RepliesI used SQLMetal to generate a DBML file, which worked fine. The problem is that since this DBML file is so big (185,000 lines at 840Kb) it takes literally hours to load in VS2008. What is the recommended way to resolve this? I tried using a third party tool call SqlMetalInclude to break the DBML up into multiple data contexts, but that tool generates only designer.cs files, not dbml files.

View 7 RepliesLinqtoSQL / asp.net MVC / C#
Ok, here is the problem:I drag and drop my database table into dbml, so i have new table diagram on dbml.For example, I have User table which has two columns(ID, NAME)Then something.design.cs automatically generates User class and definitions for ID, and NAME.
for example: [Code]....above code is automatically generated onto something.designer.cs then I made change on something.designer.cs :
[Code]....
then i added new column in database table named "Password" if i delete old diagram in dbml and drag new table, it re-writes whole something.designer.cs file, so i lose all codes i wrote before.I googled it and people say about Partial class, but i dont know how to use partial class.

I have a MVC project that has a Linq to SQL dbml class. It is a table called Clients that houses client information. I can easily get the information to display in a View using the code I followed in Nerd Dinner but I have added a stored procedure to the dbml and it's result set is of IQueryable, not IQueryable. I need to convert IQueryable to IQueryable so I can display it in the same View. The reason for the sproc is so I can pass a search string tothe sproc and return the same information as a full list but filtered on the search. I know I can use Linq to filter the whole list but I don't want the whole list so I am using the sproc.
Here is the code in my ClientRepository with a comment where I need to convert. What code goes in the commented spot.
public IQueryable<Client> SelectClientsBySearch(String search)
{
IQueryable<SelectClientsBySearchResult> spClientList = (from p in db.SelectClientsBySearch(search) select p).AsQueryable();
//what is the code to convert IQueryable<SelectClientsBySearchResult> to IQueryable<Client>
return clientList;
}

View 1 RepliesHow do I create a schema.ini file from a tab delimited file?
I have this so far:
[myFile.txt]
ColNameHeader=True
Format=TabDelimited
CharacterSet=ANSI
I think I need something like this after my last line from above:
Col1=first TEXT width 150
My text file has 7 columns, the first row is the header row. The data comes from a Micosoft SQL Server Database where the fields are of the following types:
int
nvarchar(MAX)
nvarchar(50)
I have a table of users called Users
And a view called UsersActive that filters out deactivated users.
When I create my DBML, I drag the Users table in, then I change the property on the table to point to UsersActive.
This works well, until the DBML gets re-created.
Does anyone know how to fix this?

Is there a quick and easy way to update my LINQ dbml files?Right now, if I update a Stored Procedure, I need to open the dbml designer file, delete the old SP, save, drag and drop the new SP, and save again. Dont' get me wrong, this isn't "hard"... just with all the fancy new technology out there, it would be nice to be able to just right-click and hit "update".
View 2 Repliesi'm worried about doing this since my changes will be overwritten when the dbml file is auto generated again (as they often are).
i'm thinking of doing a partial class and writing out the same properties to annotate them, but worried that it will complain about duplicates, and the reason i can't even experiment brings me to the second part of my questions...
... that, the expandable arrow on my dbml file listing is missing, right clicking and selecting "View Code" just displays an empty partial class as below...
Partial Class FPDataContext
End Class

I have two connection strings (both in Web.Config: CS_Local and CS_Production) for my DBML (Linq to SQL). In my Global.Asax/Application_Start I run some production preparation methods if the request is non-local (!HttpContext.Current.Request.IsLocal).
