Set new value for VO attribut

Question

I have function in package on database which is param is String and return value is also String(VARCHAR2).
That function calculate some field on db and return a result.That is OK
I made VO in my AM.
"SELECT package_name.func_name("string") from dual" and that is OK also.
When I start that module I recive valid result from database based on string which I passed to function.
And that works fine.
Question :
How can I change value or how can I set new value for the package_name.func_name(variable) in VO
during runtime in my application ? ^^^^^^^^

JDeveloper 9.0.3.988 1. When using stored procedures it would be better to use it in following way:
Connection conn = //get it some how
CallableStatement cs = conn.prepareCall("{call myPackage.do_something(?)}");
cs.registerOutParameter(1, java.sql.Types.VARCHAR);
cs.execute();
2. You could parameterize it like this:
CallableStatement cs = conn.prepareCall("{call " + packageName "." + funcName + "(?)}");
cs.registerOutParameter(1, java.sql.Types.VARCHAR);
cs.setString(1,"someString");
cs.execute();
String result = cs.getString(1);
where packageName and funcName are defined elsewhere
