Answer 1

assuming that your select has attributes uniquely defining the result set wrt to the contents of your target table before insertion, you can apply the following 2 steps:

 Insert into target_table
 select *
  from source_table
 where yada yada yada
   and characteristic_yada
     ;

update target_table
   set col1 = current date
 where characteristic_yada
     ;

 commit;

make sure to issue both commands inside the same transaction as shown. also be aware that characteristic_yada must be aplicable to source and target table alike and that the suitability of characteristic_yada needs to be checked before each application of the statements unless they refer to pks/aks of the taregt table
