[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

One query is producing the below table :-

answer |  count  |  avg
  a1       3         14
  a2       2         10

How to convert this to a single row table ?

count | avg_a1  | avg_a2
  5       14       10
 
Regards,
Arup Rakshit
