आप इसे ऐसे ही क्यों कर सकते हैं:
order by ImpFile DESC, ImpTime desc
नहीं, आप जो दिखा रहे हैं उसका परिणाम नहीं है। इसका परिणाम यह होता है:
Import12 2012-05-16 09:55:37.387
Bart Import12 2012-05-16 09:55:37.387
Sasha Import12 2012-05-16 09:55:37.387
John Import12 2012-05-16 09:55:37.383
Imp01 2012-05-16 09:54:02.477
Ann Imp01 2012-05-16 09:54:02.477
Mark Imp01 2012-05-16 09:54:02.477
Sam Imp01 2012-05-16 09:54:02.477
देखें यहां उदाहरण के लिए

मेरे पास आपके लिए एक सुझाव है। शायद कुछ ऐसा:
परीक्षण डेटा
DECLARE @T TABLE(Name VARCHAR(100),ImpFile VARCHAR(100),ImpTime DATETIME)
INSERT INTO @T
([Name], [ImpFile], [ImpTime])
VALUES
('Sam', 'Imp01', '2012-05-16 09:54:02.477'),
('Ann', 'Imp01', '2012-05-16 09:54:02.478'),
('Mark', 'Imp01', '2012-05-16 09:54:02.477'),
('John', 'Import12', '2012-05-16 09:55:37.384'),
('Bart', 'Import12', '2012-05-16 09:55:37.387'),
('Sasha', 'Import12', '2012-05-16 09:55:37.385');
