       1. SELECT * FROM ALL_CONS_COLUMNS A 
      JOIN ALL_CONSTRAINTS C ON A.CONSTRAINT_NAME = C.CONSTRAINT_NAME 
      WHERE C.TABLE_NAME = <your table> AND C.CONSTRAINT_TYPE = 'P'
   2.  SELECT * FROM ALL_CONS_COLUMNS A 
       JOIN ALL_CONSTRAINTS C  ON A.CONSTRAINT_NAME = C.CONSTRAINT_NAME 
       WHERE C.TABLE_NAME = <your table> AND C.CONSTRAINT_TYPE = 'R'

    1st is for primary key & 2nd one is for foreign key……….I think this may help you.
