-- use rownum
-- here i consider only first 2 rows.

dbadmin@mutation_mutation > select rownum,deptno from dept;

    ROWNUM     DEPTNO
---------- ----------
         1         10
         2         20
         3         30
         4         40

dbadmin@mutation_mutation > create table another_dept as select deptno from dept where rownum < 3;

Table created.

dbadmin@mutation_mutation > select * from another_dept;

    DEPTNO
----------
        10
        20

dbadmin@mutation_mutation >

If you want the first 100 records in a specific order
here is the query else it will pick randomly 100 records.

select * from(select rownum rn, col1,col2, from (select col1, col2 ... ,rownum rn,
from table1
order by col1.... ))
where rn < 1
