Here is an example, based on your message you care about the foreign key at the bottom.
CREATE TABLE dept
(deptno number(2)
CONSTRAINT dept_deptno_pk PRIMARY KEY
,dname varchar2(14)
,loc varchar2(13));
CREATE TABLE emp
(empno number(4)
CONSTRAINT emp_empno_pk PRIMARY KEY
,ename varchar2(10)
,job varchar2(10)
,mgr number(4)
...
,deptno number(2)
CONSTAINT emp_deptno_fk
REFERENCES dept(deptno))
