Hello Mark
Thank you for your answer.
Actually what I'm trying to convert is not the jdbc results but the parameters for the query prepared statement.
Let say I have a query like this one:
select *
from employees
where emp_number in (${par_emp_number})
The ${par_emp_number} parameter must be an interger list of employee numbers because the type of the emp_number attribute of the employe table is number. In the policy I get the employee numbers in a comma separated string like "100,200,300,400,500" which I split with the split assertion. In this way I get a string multivalued variable. I tried then to convert it in a int multivalued one like you suggest, but unfortunately the conversion string to int fails.
Regards,
John
