Randall:

You can't use a subquery in a SET. You might try the following:

     > UPDATE  lp_test_table lp1
     > SET NEXT_OB_TMSTMP  = ob_tmstmp
     >  WHERE ob_tmstmp = (SELECT min(OB_TMSTMP) FROM  lp_test_table lp2
     >                        WHERE lp2.lead_num = lp1.lead_num
     >                               AND lp2.OB_TMSTMP > lp1.OB_TMSTMP);

My only concern about your code would then be whether or not you have an ob_tmstmp greater than the current one.
