If your user account has autotrace configured by the DBA, you can use the "SET AUTOTRACE ON STATISTICS" command to turn on execution statistics reports on query statements. The tutorial exercise bellow shows you a good example:

SQL> CONNECT HR/retneciyf

SQL> SET AUTOTRACE ON STATISTICS

SQL> SELECT E.LAST_NAME, E.SALARY, J.JOB_TITLE
  2  FROM EMPLOYEES E, JOBS J
  3  WHERE E.JOB_ID=J.JOB_ID AND E.SALARY>12000;

LAST_NAME             SALARY JOB_TITLE
----------------- ---------- -----------------------------
King                   24000 President
