how to see generated sql from a linq query

Question

Just trying to get the sql that is generated by a linq query.

Answer 1

The easiest way i could suggest is to go with Database Log. Put Logafter initializing DataContext and you will be able to track whatever is done by EF on visual studio output window.

  DataContext db = new DataContext();
  db.Database.Log = generatedSQL =>
   {
      Debug.WriteLine(generatedSQL);
   };

Answer 2

Use SQL Profiler if you are using SQL Server as your database.

Answer 3

There are 3 ways do that.

1.You can use LINQPad.It's Free http://www.linqpad.net/

2.You can use SQL Server Profiler inside the Sql Server (Tools --> SQL Server Profiler)

3.You can use Visual Studio Debugger for Generate T-Sql.(with any visual studio version)

Answer 4

Another way

From the MSDN article How to: Display Generated SQL (LINQ to SQL)

Set the DataContext.Log Property to Console.Out and you'll see it in the console

Answer 5

With Linq2Sql

dc.GetCommand(query).CommandText

see http://msdn.microsoft.com/en-us/library/system.data.linq.datacontext.getcommand.aspx for more info.

But I usually use LinqPad
