IS there static variables in oracle 9i??

Question

Hi,
I have a requirement.
I am establishing an orcale 9i connection from my .net application.
Now I am calling an SP and it has a global count variable initialized to 0, and It fetches a count of * from one table and also there are other functionality that the SP does.
Now I want to persisit this count variable's value , so that next time the SP is called ( in the same connection), I will make a check that if the count variable is not 0 then dont execute the query to populate the count variable.
Normally in java, .net etc... we can create static variables for this purpose.
Can the same be done in PL/SQL?
If not what would be the alternative?
Thanks folks.
