Answer / jyothi
there is only one way to to re-arrange the table
that is views...
create view <view-name>as select <fields> from <tablename>
.........
for example..
create view vw as select empno,empdesig,empname,empcountry
from <tablename>...
(u can get message that is view created)
just display the data using viewname(vw)..

try this
create table emp1 as select
empno,empdesig,empname,empcountry from emp
this would creat a new table named as emp1 and
u can retrive the data from this table as of emp
but constraints,indexs which u have on emp table are
created on this emp1 table

Hi, Can anybody please explain me the flow of the below query. I am not able to understand how this query works. This query is for finding the Nth highest salary.. SELECT DISTINCT (a.sal) FROM EMP A WHERE &N = (SELECT COUNT (DISTINCT (b.sal)) FROM EMP B WHERE a.sal<=b.sal); If N = 2 then second highest salary will be the o/p. If N = 3 then third highest salary will be the o/p. and so on.. Thanks, Nitin
