Linq存儲過程插入沒有結果

我試圖用存儲過程與Linq To SQL插入數據。我沒有收到任何錯誤消息，我的數據也沒有插入。代碼是在VB中，因爲我也在這個項目中使用XML。Linq存儲過程插入沒有結果

代碼

 Using db As New booksDataContext() 

     db.testprocedure("kkk") 
     db.SubmitChanges() 

     End Using

存儲過程

ALTER PROCEDURE testprocedure 

(
@test varchar(50) 
) 

AS 
BEGIN 
INSERT INTO test (testcolum) 
VALUES (@test) 
END

我能本身它會在這個功能時，我調試和它的返回0

<Global.System.Data.Linq.Mapping.FunctionAttribute(Name:="dbo.testprocedure")> _ 
Public Function testprocedure(<Global.System.Data.Linq.Mapping.ParameterAttribute(DbType:="VarChar(50)")> ByVal test As String) As Integer 
    Dim result As IExecuteResult = Me.ExecuteMethodCall(Me, CType(MethodInfo.GetCurrentMethod,MethodInfo), test) 
    Return CType(result.ReturnValue,Integer) 
End Function

我已經做了選擇作品perfekt所以它沒有錯datacontext

Sub SelectAllBooks() 

    Dim db As New booksDataContext() 

    For Each book In db.SelectBooks("Madde") 

     Dim title = book.title 
     Dim author = book.author 
     Dim genre = book.genre 
     Dim price = book.price 
     Dim publish_date = book.publish_date 
     Dim description = book.description 
     Dim bookid = book.bookid 


     Console.WriteLine(title & " " & author & " " & genre & " " & price & " " & publish_date & " " & description & " " & bookid) 

    Next 
    Console.ReadLine() 
End Sub

謝謝您的幫助
