|current_spid||smallint||Shows the system process id (SPID) for the current SQL Server's connection. Is not nullable.|
|request_type||nvarchar(60)||Shows the I/O request packet (IRP) type.

|request_state||nvarchar(60)||Shows the state of the I/O request in NSO. Possible values are REQ_STATE_RECEIVED, REQ_STATE_INITIALIZED, REQ_STATE_ENQUEUED, REQ_STATE_PROCESSING, REQ_STATE_FORMATTING_RESPONSE, REQ_STATE_SENDING_RESPONSE, REQ_STATE_COMPLETING, and REQ_STATE_COMPLETED. Is not nullable.|
|request_id||int||Shows the unique request ID assigned by the driver to this request. Is not nullable.|
|irp_id||int||Shows the unique IRP ID. This is useful for identifying all I/O requests related to the given IRP. Is not nullable.|
|handle_id||int||Indicated the namespace handle ID. This is the NSO specific identifier and is unique across an instance. Is not nullable.|
|client_thread_id||varbinary(8)||Shows the client application's thread ID that originates the request.

|client_process_id||varbinary(8)||Shows the process ID of the client application if the client application runs on the same machine as SQL Server. For a remote client, this shows the system process ID that is working on behalf of the client application. Is nullable.|
|handle_context_address||varbinary(8)||Shows the address of the internal NSO structure associated with the client's handle. Is nullable.|
|filestream_transaction_id||varbinary(128)||Shows the ID of the transaction associated with the given handle and all the requests associated with this handle. It is the value returned by the get_filestream_transaction_context function. Is nullable.|
