Difference between an implicit & an explicit cursor.?
Answer Posted / v.ramesh
Implicit cursor is taken care by oracle server only,when we write any statement or query in the SQL editor,in that case oracle server create some memory for that and do operation on that query and finally erase the space as well
in case of Explicit cursor,manually like we need to create the Cursor and open.fetch the data and close the cursor.
we have one more alternative for this,if we will create cursor we need to user FOR LOOP mechanism in this case all exlicit cursor are not needed i.e OPEN<FETCH<CLOSE
