I've just checked, and there is no ExecutionLog2 table in my ReportServer database. There is an ExecutionLog table there, though, and so I checked that out. I ran the report from the Intranet website using this systax:

select * from ExecutionLog order by TimeStart DESC

but it didn't show the execution of the .RDLC report. In fact, the last report in that table is from earlier this month, so I suspect that when a report is run using a .RDLC file, it doesn't effect the ReportServer.
