SQL server profiler not showing LINQ To Sql queries

Question

I am trying to view SQL generated by Linq to SQL in the SQL Server Profiler (2005).

I can see the sql sent to the server from anything except for linq to sql.

I'm betting that I need to change event selections for the trace, but not sure what else to select.

I am currently only selecting this: SQL:StmtCompleted - TextData & SPID

I don't want to use data context logging nor the SQL Debug Visualizer. I need to use the profiler.

Why can I not see the LINQ to SQL queries?

Thanks.

EDIT

I added SQL:BatchCompleted and that hasn't helped.

EDIT 2

I added the event RPC:Completed which is found under the Stored Procedures category in event selection. This worked!

You need RPC call - the queries are executed as exec_sql.

Figures...I'd still expect stmt completed to work surprised it doesn't – JoshBerke Apr 08 '09 at 13:02

For SQL Server Profiler 2017 (v14.0.17099) add the RPC:Starting property like so: Menu \ File \ Properties \ Events Selection \ Stored Procedures \ [X] RPC:Starting. Run – Micah Epps Jul 26 '19 at 13:00

Are you including enough of the options in the SQL Profiler to see the BatchCompleted events, too?

There is also an option in the data context class to enable log in the client side. When log is enabled is possible to see the queries.

Had the same problem and none of the solutions above worked for me.

What worked for me was adding ToList() enumerator to the query.

Before:

var data = null == id ?
                   (from ...
                    select new
                    {
                        ...
                    })
                :
                   (from ..
                    select new
                    {
                        ...
                    });

After:

var data = null == id ?
                   (from ...
                    select new
                    {
                        ...
                    }).ToList()
                :
                   (from ..
                    select new
                    {
                        ...
                    }).ToList();

foreach (var obj in data)
{
   xxx = obj.somename; --> now you can see the sql query in Profiler
