Question

How can i look at generated sql query by LINQ? I tried LINQPad but as i understood i have to write LINQ statements into LINQPad.

Any ways without SQL Profiler?

I use it here:

public IEnumerable<PeopleTalesCategory> GetAllCategories()
{
    return _dataContext.PeopleTalesCategories.OrderBy(c => c.PositionInMenu).ThenBy(c => c.NameAn);
}

If you are using Linq To Sql you can use a StringWriter to get the Sql generated by the Linq To Sql. Here is an example that setup to the DataContext the Log and execute a simple query to finally show in sqlLinqToSql.Text the SQL.

DataClasses1DataContext db = new DataClasses1DataContext();
StringWriter sw = new StringWriter();
db.Log = sw;

this.gridLinqToSql.DataSource = db.Customers.Where(c => c.CustomerID.StartsWith("A"));
this.gridLinqToSql.DataBind(); //Here is when the Linq query will be executed.

sqlLinqToSql.Text = sw.GetStringBuilder().ToString();

If you are using Linq To Entity, it’s different. You need to call from the ObjectQuery the ToTraceString():

var cust = (from c in context.Customers select c);
string sql = ((ObjectQuery)cust).ToTraceString();
