You need to start using Exception coding in your sql.

Basiclly ...

Begin
  ....
  coding
  ...
Exception
  When Error
  Then

Do this
End;

Encase your sql statements in the begin/exception/end construct and code accordingly. Here is an example. In this case, on thye update statement, if I encounter an error, I go to the Exception block. This block does not bother about specific errors, which you can do, I just handle ever error the same. I set some variables and call my error handling routine, update_log_error. Look at some of the Oracle books under EXCEPTIONS. The ORACLE PL/SQL PROGRAMMING book by Steven Feurstein is a real good source for this.

Begin

     Update prov$.prof_fed_tax_ids
     Set tax_id_status = 'INVALID'
     Where prov_id    = cur_inv_pfti_rec.prov_id
       and fed_tax_id = cur_inv_pfti_rec.fed_tax_id;
   Exception
     When Others
     Then
       v_ongoing_load_id       := cur_inv_pfti_rec.ongoing_load_id ;
       v_external_prov_id      := cur_inv_pfti_rec.external_prov_id;
       v_external_grp_id       := ''                               ;
       v_external_agree_id     := ''                               ;
       v_ongoing_table_name    := 'ONGOING1_PROF_FED_TAX_IDS'      ;
       v_ongoing_column_name   := ''                               ;
       v_ongoing_default_value := ''                               ;
       v_discard_value         := ''                               ;
       v_discard_status        := 'FATAL'                          ;
       v_discard_reason        := sqlerrm                          ;
       update_log_error
         (
           v_ongoing_load_id,
           v_external_prov_id,
           v_external_grp_id,
           v_external_agree_id,
           v_ongoing_table_name,
           v_ongoing_column_name,
           v_ongoing_default_value,
           v_discard_value,
           v_discard_status,
           v_discard_reason
         );

End;
