Hi all,
    I have a table emp. using where condition can i get the result 
Take the example below.

select ENAME,ORIG_SALARY from employee where (ename='Tom' and 
orig_salary=2413)or(orig_salary=1234 )

if the fist condition(ename='Tom' and orig_salary=2413) is satified then 10 
rows will be returned, for the second condition (orig_salary=1234 ) there 
are 20 rows will be returned.
The order of display should be

The first 10 rows then
next 20 rows.
Thanks & Regards,

In response to
