Hi -

I've created the following SuperType object in Oracle :

CREATE OR REPLACE TYPE CT_CALC_UT as object (
ct_plant_nm varchar2(50),
ct_value number,
MEMBER function get_PlantNm return varchar2,
MEMBER procedure set_CT_Val(pi_ct_val in number)
) not final

and the following Type Body :

create or replace type body ct_calc_ut is

member function get_PlantNm return varchar2 is
v_plant_nm varchar2(50);
begin
v_plant_nm := self.ct_plant_nm;
return v_plant_nm;
end get_PlantNm;

member procedure set_ct_val(pi_ct_val in number) is
begin
ct_value := pi_ct_val;
end set_ct_val;

end;

Also, I've created the following subtype with it's own type body:

CREATE OR REPLACE TYPE CT_CALC_SP_UT UNDER CT_CALC_UT
(
Sed_Basins_in_service number(2),
Sed_Raw_flow_rate number(7,3),
Sed_flocc_free_cl number(7,3),
Sed_settled_free_cl number(7,3),
App_ph number(7,3),
Fltrs_free_cl number(7,3),
Fltrs_flow_rate number(7,3),
Fltrs_temp number(7,3),
Fltrs_ph number(7,3),
MEMBER function displayVals return varchar2
)

create or replace type body ct_calc_sp_ut is
member function displayVals return varchar2 is
....
...
...
...
...
v_ct_value := v_tot_LGiardia_Rmvl_Cred / v_log_giardia_removal_const

self.set_ct_val(v_ct_value); !!!! Error Message is Coming here !!!!!

....
....
end displayVals;

I keep getting an error message, Compilation errors for TYPE BOD
BMARINI.CT_CALC_SP_UT

Error: PLS-00363: expression 'SELF' cannot be used as an assignmen
target
Line: 138
Text: self.set_ct_val(v_ct_value);

Error: PL/SQL: Statement ignored
Line: 138
Text: self.set_ct_val(v_ct_value);

I'm not sure what is going on with this....I have seen plenty o
examples where an object type is being modified from within
procedure...and I'm prety stumped as to what is going on. If anyon
has any help...or ideas, please let me know.

Thanks
