Display SQL Query used by entity framework

Sometimes you may need to look at the command, that’s created from your i.e. LINQ query and sent to database. Let’s say you have query like this:

1
2
var q = from m in e.master
           select m.t.Length;

You can cast the q into ObjectQuery and use the ToTraceString method to see the query:

1
Console.WriteLine(((ObjectQuery)q).ToTraceString());

This will show you the query, that’s sent to store you’re using (mainly relational database). Neat and easy.
