Is it possible to update a CURSOR in which we have used JOIN on 2 tables ORDERS and TRANSACTIONS? Why or Why not? How can we proceed to UPDATE any of these tables?
When we use JOIN on one (self join) or more table inside a cursor declaration then a read-only cursor will be created. We cannot update the read-only cursor.
If we want to update any of the tables used in the JOIN then we have to declare a separate cursor for all the tables and an individual logic has to be built in order to update each DB2 table.
