I have a file contains some numbers in UNIX, i need to create a table in Oracle and those numbers that are in UNIX text file insert into Oracle table.

Please Give a solution for this....

you need to use sql*loader

Use oracle_loader load txt,csv,dat file into oracle table but
u need to define a oracle directory here mydir is oracle directory ,
and also ur file will be under oracle directory path

Example

create table emp_ext (empno number(8), ename varchar2(30),sal number, hiredate date)
organization external ( type oracle_loader default directory mydir
access parameters ( records delimited by newline fields terminated by ',' )
location ('emplist.csv') ) parallel 5 reject limit 200;
