How can you obtain the SQL generated code by Linq ?

Perharps it is obvious but .. I am new with Linq to SQL.

Cheers

Check out this post on how you can have all of the SQL executed by LINQ to SQL in the output window in Visual Studio. This is what I do on my project and it works great.

LINQPad is also a handy tool for this sort of thing… think of it as a lightweight version of SQL Server Management Studio for LINQ to SQL.

In MSDN Library, I found 2 another solutions (easier) :

Dim db As New NorthwindDataContext

Console.WriteLine(”solution 2 : msdn”)
db.Log = Console.Out

Dim q = From c In db.Customers _
From o In db.Orders() _
Where (c.CustomerID = o.CustomerID) _
And c.Country = “France” _
Order By c.CustomerID _
Select o.OrderID, o.ShipCity, c.CustomerID

DataGridView1.DataSource = q

Console.WriteLine(”solution 3 : msdn”)
Dim dc As Common.DbCommand = db.GetCommand(q)
Console.WriteLine(vbNewLine & “Command Text: ” & vbNewLine & dc.CommandText)

These 3 solutions run only with Linq (use db.Log).

The syntax of the second solution seems strange to me :
db.Log = Console.Out
In fact, we send to the console the result of the log of db, I think that :
Console.Out = db.Log
would be more logical

I think it is also possible to do that with SQL Profiler but I don’t know how to use it.

It works fine but now I want something like this
If (selectedProduct!=null )
{
CatGridview.visible=true;
CatGridview.datasource= selectedProduct;

}
Or empty or what ever condition that tell me that there is any value in selectedProduct
So help me out on this how can I make sure that there is any value or not
