I made a change to a stored proc, and now this code is complaining:

Procedure or function 'AgentFormList_Get' expects parameter '@ClientID', which was not supplied.

The error is valid, there are a few more parameters to supply after I updated the stored proc.  Do I edit this DataContext form code manually?  It looks like it was computer generated.

		[global::System.Data.Linq.Mapping.FunctionAttribute(Name="dbo.AgentFormList_Get")]
		public ISingleResult<AgentFormList_GetResult> AgentFormList_Get([global::System.Data.Linq.Mapping.ParameterAttribute(Name="AssetID", DbType="Int")] System.Nullable<int> assetID, [global::System.Data.Linq.Mapping.ParameterAttribute(Name="AssetSID", DbType="Int")] System.Nullable<int> assetSID)
		{
			IExecuteResult result = this.ExecuteMethodCall(this, ((MethodInfo)(MethodInfo.GetCurrentMethod())), assetID, assetSID);
			return ((ISingleResult<AgentFormList_GetResult>)(result.ReturnValue));
		}
		

Open in new window



I've not done much with LINQ.

How do I get everything updated so that LINQ uses the updated stored procedure, etc?

From what I've known, this procedure was done through SQLMetal. It's  a command-line tool called SQLMetal that generates entity classes, properties, and associations automatically.

You can use that tool to regenerate the stored procedure you've made some update by running the SQLMetal tool on the database.

To get you started, you can run this on the SQLMetal tool: (By the way, I found my SQLMetal.exe file in this location: C:\Program Files (x86)\Microsoft SDKs\Windows\v8.0A\bin\NETFX 4.0 Tools)

sqlmetal /server:pc-ferracchiati /DATABASE:People /user:sa
         /password:sapass /sprocs /code:People.cs

Open in new window

Change the server, database, username & password accordingly.

To give you an idea on how to use the SQLMetal tool, follow this: SQLMetal tool guide

Tell me how it goes.

I have the same directory path:

C:\Program Files\Microsoft SDKs\Windows\v7.0A\bin\NETFX 4.0 Tools

How can I know for sure if the file was generated using SQLMetal or some other way?

Is there a way to do this through the Visual Studio IDE (the GUI environement) instead of via the command line?

You will know if it was when you'll try to compare the generated results of the file based on the parameter /code:"filename.cs" to the one you have.

Yes there is. First of all, create a batch file to execute the SQLMetal command passing in server, database, user, password parameters required for the program. Second, there is a step by step process that you can add into your Visual Studio IDE to automate the task:

Thank you for this information.

I managed to get a hold of one of the other developers and asked him their process for updating LINQ / datacontext etc.

Here are the steps he gave me:

1)  Double-click on the .dbml file
2)  When it opens, delete the existing data class.
3)  Open the Server Explorer
4)  Find the modified Stored Proc
5)  Drag it over to the list of data classes

This will update everthing so that if there are more (or fewer) params expected this will get updated everywhere.
