hi,
try this query
Instead of grouping by t.pos_date group by TO_CHAR(T.POS_DATE, 'Month')
SELECT DISTINCT TO_CHAR(T.POS_DATE, 'Month') Month,count(*) Date_rec,sum(t.amount) amount,
t.Asset, avg(t.amount) avg_ora_col,Sum(t.amount)/ count(*) "Normal Average"
from pos t
group by TO_CHAR(T.POS_DATE, 'Month'),t.asset
hope this will work
Regards,
