Updating Long Field

Hi:

   I need to know how I can compute the results of adding two fields in    oracle e.g. given below.

	table : Employee
                emp_address VARCHAR2(2000)
                emp_resume  VARCHAR2(2000)
        
        table : temp_emp
	        emp_add_resume LONG;

   I need to have a trigger on table Employee which concatenates the    emp_address and emp_resume fields and inserts a record into the    temp_emp.emp_add_resume field.

   Since oracle VARCHAR fields has a limit of 2000 the result of the    concatenatation will be greater than the limit.    As far as I know PL/SQL variables cannot exceed 2000 characters,    I would like to know how this can be done...

   Thank you in advance...
