  • Imports LinqTest.LinqSql

    Public Class Formdemo

    Private db As New LinqSql.ProductDataContext()

    Private Sub Formdemo_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

     

    db.Log = Console.Out  'Add This Line to Your application , and you can view the Sql Statement in the OutPut Windows when Debug the Program

     

    'Dim emplist = From emp In db.Employees _

    ' Where emp.Id < 20 _

    ' Select emp

    'Me.EmployeeBindingSource.DataSource = emplist

     

     

    Dim emplist = db.ExecuteQuery(Of Employee)("select address,city,id,lastname,firstname,postalcode,title from employee where id<50")

    'Dim emplist = db.ExecuteQuery(Of Employee)("select * from employee where id<20")

    Me.EmployeeBindingSource.DataSource = emplist

     

    'Me.EmployeeBindingSource.DataSource = db.Employees

     

    End Sub

  • Hello Gordon,

    theres a tool for SQL Server thats called "Profiler". You can view every SQL Statement that is reveived by the Sql server.
    Of Course - you have to work a little with the Debugger to find that out.
    It's maybe not the most beautiful way, buts it works until you can find a way that suits better your needs.

  • Thansk very much Esrever,

    I have used the Sql Profiler before, but I dont want to used it in this Case,

    as you said, it will be the last solution if there is really no other ways to do it.

  • I beleve the request is how to look at the query in debug mode when querying against EDM in the same way you can with LINQ to SQL, as opposed to using SQL Profiler.

     

    The trick for it is to get tot eh ENtity Command tree and in there, is the TSQL.

     

    HEre's a previous thread that shows how to accomplish this.

  • In addition there is a new feature that will arrive with beta 3 of the entity framework (getting closer but still not quite ready yet) that will make this much easier...

    Any update on what this "feature" is and how to use it now that Beta 3 is out?

  • I believe this is implemented through a method named ToTraceString(). If I figure out how to use it before you do, I'll let you know. ;-) and vice-versa.

  • I have visual studio 2008 sp1 installed.

    Where's this new feature?

  • There is now a ToTraceString() method on both ObjectQuery and EntityCommand, which returns the store-provider's query statement.
