tough time with cursors

I am getting an error to which I am sure is because of a subquery within a cursor declaration. That may sound way wacked out to someone who knows what they are doing, but I was told that you cannot have a variable that hasn't been set yet in the cursor declaration, so I wasn't sure on another way to do it.

Here is the code.

Code:

	--cursor declaration
	cursor c_rentalInvoices is 
		select rid.invoice_number, rid.date_returned
		from rental_invoices ri, rental_invoice_details rid 
		Where 
			ri. member_number = Select member_number From members Where last_name = p_lastName AND first_name = p_firstName
			And
			ri. invoice_number = rid.invoice_number;

Thanks for any help that you can give me

you can use the subquery into declaration of cursors, see the following example:

create or replace function no_of_employee(p_deptno in number)
return number is

cursor c_emp is
select * from emp
where deptno = (select deptno from dept where deptno=p_deptno);

begin

return null;

end;
/

so there doens't really seem to be anything missing from the cursor that I am using then. Hmm I guess that is a good thing, I just have to look elsewhere for the problem.

Thanks for the help
