hi lists

can anybody help me for the flwng :

i need to do calculation dividing phy reads value/db block gets

i am following the principle

select decode(name,'physical reads',value)/decode(name,'db block gets',value)
from v$sysstat
where name in ('db block gets','physical reads')

just this query is returning notthing.

i tried with to_number function also, that is not also returning anything.

is there any trick to solve this.
