123            CURRENT  130      2012-10-16 13:00:00.000
123            AVG      140      2012-10-16 13:00:00.000
123            MIN      100      2012-10-16 13:00:00.000

123, 130, 140, 100, 160 2012-10-16 13:00:00.000

Answer 1

select 
  devicename, 
  MAX(CASE WHEN Name = 'CURRENT' THEN value ELSE NULL END), 
  MAX(CASE WHEN Name = 'AVG' THEN value ELSE NULL END), 
  MAX(CASE WHEN Name = 'MIN' THEN value ELSE NULL END), 
  MAX(CASE WHEN Name = 'MAX' THEN value ELSE NULL END), 
  timestamp 
from table1
GROUP BY devicename, timestamp
