Trigger ignore all exceptional handling in SP

Informix version : 12.10.FC6AEE Platform : Linux Requirement: 1) Invoke of the following stored procedure happens on INSERT TRIGGER level and it need to be at trigger level. I had written a stored procedure with exceptional handling. Sample Code =========== create procedure fn_ins_tevoc ( _p_ev_oc_id integer, _p_user_id varchar(50), _p_ev_mkt_id integer, _p_ev_id integer, _p_hcap_value decimal(12,2), _p_hcap_score integer, _p_cashout_avail decimal(12,2), _p_bir_cashout_avail decimal(12,2), p_debug smallint default 0 ) define nrows integer; define l_var_created_tm datetime year to second; define l_var_created_by varchar(18,10); define l_var_last_updated datetime year to second; define l_var_updated_by varchar(18,10); define l_var_ev_type_id integer ; define l_var_ev_class_id integer ; define l_var_class_category varchar(16) ; define l_tabname varchar(100) ; define l_change_keys smallint ; define sql_err int; define isam_err int; define error_info char(70); define l_msg varchar(255) ; if p_debug = 1 then set debug file to "/tmp/fn_ins_tevoc.TRC"; trace on ; end if begin on exception set sql_err, isam_err, error_info let l_msg = "where ev_oc_id=" || trim(to_char(_p_ev_oc_id)) ; execute procedure log_error(p_op="INSERT", p_tabname=l_tabname, p_cond=l_msg, p_err="isam_err=" || to_char(isam_err) || " sql_err =" || to_char(sql_err),p_aff_module="pop_tevoc_full_details", p_from_mesg="" ); --raise exception sql_err, isam_err, error_info ; RAISE EXCEPTION -208, 0; end exception with resume ; --Calculate the required fields execute procedure get_ev_class_n_type_id(_p_ev_id,"FROM tevoc where ev_oc_id="|| to_char(_p_ev_oc_id)) into l_var_ev_class_id, l_var_ev_type_id ; let l_var_class_category = get_category_evtab (_p_ev_id,"FROM tevoc where ev_oc_id=" || to_char(_p_ev_oc_id) ) ; let l_var_created_tm = current ; let l_var_created_by = user ; let l_var_last_updated = l_var_created_tm ; let l_var_updated_by = l_var_created_by ; let l_tabname = "tevoc_full_details" ; --if not exists (select ev_oc_id from tevoc_full_details where ev_oc_id = _p_ev_oc_id) then insert into tevoc_full_details ( ev_oc_id,user_id,ev_mkt_id,ev_id,hcap_value,hcap_score,cashout_avail,bir_cashout _avail,ev_type_id,ev_class_id,class_category,created_tm,created_by,last_updated, updated_by) values ( _p_ev_oc_id,_p_user_id,_p_ev_mkt_id,_p_ev_id,_p_hcap_value,_p_hcap_score,_p_cash out_avail,_p_bir_cashout_avail,l_var_ev_type_id,l_var_ev_class_id,l_var_class_ca tegory,current,user,null,null); --end if -- Of not exists end -- Of begin if p_debug = 1 then trace off ; end if end procedure ; Invoke from trigger =================== create trigger tmp_insert_tevoc insert on tevoc referencing new as _new for each row ( execute procedure "informix".fn_ins_tevoc(_p_ev_oc_id= _new.ev_oc_id ,_p_user_id= _new.user_id ,_p_ev_mkt_id= _new.ev_mkt_id ,_p_ev_id= _new.ev_id,_p_hcap_value= _new.hcap_value ,_p_hcap_score= _new.hcap_score , ,_p_cashout_avail= _new.cashout_avail ,_p_bir_cashout_avail= _new.bir_cashout_avail,p_debug= 1 )); Issue 1) According to IBM official site ( http://www.ibm.com/support/knowledgecenter/en/SSGU8G_12.1.0/com.ibm.sqls.doc/ids _sqs_1351.htm ) it mentioned the following : No ON EXCEPTION Support in Triggered Actions The ON EXCEPTION statement has no effect when it is issued from an SPL routine in the following calling contexts: in a trigger routine, in the Action clause or the Correlated Action clause of a trigger on a table, in the Action clause of an INSTEAD OF trigger on a view. When a UDR includes ON EXCEPTION in any of these contexts, the database server ignores the ON EXCEPTION statement. Observation ----------- 1) If I insert a new record in into target table(tevoc) it trigger take effects and it failed on "insert into tevoc_full_details". i) the exceptional is not being trigger ii) the record is being rejected on tevoc table as well. Questions 1) Is that a way to get the exceptional handling to take effect even it is being called from trigger? 2) Is that a way to get the record inserted (at tevoc table) in event of observation ii) above happen ? Appreciate your input.
