I have two different tables what they have required from me to join them in one view and to make form on it which allow the user to search...when i told them that this can not be done becuase the field are different they told me that i can put where no same fiel select null..Is this is correct
for example
if i want to combine the value of two table employee and other
if i use the following statment
select emp_id as "id", emp_office_id as "office from employee
union all
select other_id as "id" , null as "office" from other ;

Is emp_office_id a number?
null defaults to varchar2
try:
select emp_id as "id", emp_office_id as "office" from employee
union all
select other_id as "id" , to_number(null) as "office" from other ;
And can you have a read of the orafaq forum guide and follow what it says about formatting posts in future please.
