In SQL Server 2005 and later, the information in the TextData column captured for the RPC:Starting and RPC:Completed events is also available in the BinaryData column. For performance reasons, it is more efficient to include the BinaryData column and omit the TextData column, when adding these events to the trace. If the BinaryData column is included, Profiler will extract the text from that column and display it in the lower event details pane, even if the TextData column was not included for the event.
However, a problem occurs when the trace does not contain ANY events with the TextData column. If such a trace is open in Profiler, the TextData column is not displayed in the grid, and the text information associated with the RPC:Starting and RPC:Completed events is not displayed in the lower event detail pane, even though the information is available in the BinaryData column.
