Answer Posted / vamsi krishna
the reason behind this is rownum will be generated only
after selecting the row from the table.hence when you are
using inline views ,the outer select statement is having a
rownum and inner select statement is having a rownum,so due
to the ambiguity your query is not working.
i give the following change to ur query.
SELECT * FROM
(SELECT rownum as r1,TITLE FROM MOVIE )
WHERE r1 > 4;
