Hi,
I have a table like this:
SQL> select * from test;
ID PRICE
---------- ----------
1 1
1 3
1 4
1 5
1 6
I need to get the second largest price and I was using
the ROWNUM.
For the following statement, the result makes sense:
SQL> select * from test where rownum < (select
count(*) -1 from test);
ID PRICE
---------- ----------
1 1
2 3
3 4
But the rest twos didn't return anything:
SQL> select * from test where rownum=(select count(*)
-1 from test); -- supposed to return 5 ???
no rows selected
SQL> select * from test where rownum > (select
count(*) -1 from test); -- supposed to return 6 ???
no rows selected
I vaguely remember that ROWNUM only works in < case,
why is that? Thank you!
