Inserting values in a table from a view report in Application Express

Question

Hello.
I have several tables with the sql bellow:
Employee
CREATE TABLE "Employee"
(     "Employee_ID" NUMBER,
"Name" VARCHAR2(12) CONSTRAINT "NAME_EMPLOYEE_NN" NOT NULL ENABLE,
"Surname" VARCHAR2(10) CONSTRAINT "SURNAME_EMPLOYEE_NN" NOT NULL ENABLE,
"Address" VARCHAR2(50) CONSTRAINT "ADDRESS_EMPLOYEE_NN" NOT NULL ENABLE,
"Telephone" VARCHAR2(10),
"Personal_ID_Number" VARCHAR2(13),
"Date_of_Employment" VARCHAR2(10) CONSTRAINT "DATA_NN" NOT NULL ENABLE,
"Salary" NUMBER(6,0),
CONSTRAINT "Employee_ID_con" PRIMARY KEY ("Employee_ID") ENABLE,
CONSTRAINT "Employee_CON" UNIQUE ("Personal_ID_Number", "Telephone") ENABLE
Patient
CREATE TABLE "PATIENT"
(     "Patient_ID" NUMBER,
     "Name_Patient" VARCHAR2(13) CONSTRAINT "NAME_PAT_NN" NOT NULL ENABLE,
     "Surname_Patient" VARCHAR2(10) CONSTRAINT "SURNAME_PAT_NN" NOT NULL ENABLE,
     "ADSRESS_PATIENT" VARCHAR2(50),
     "TELEPHONE_PATIENT" VARCHAR2(10) CONSTRAINT "TEL_PAT_NN" NOT NULL ENABLE,
     "EMPLOYEE_ID" NUMBER CONSTRAINT "DENTIST_PAT_NN" NOT NULL DISABLE,
     CONSTRAINT "PK_PATIENT" PRIMARY KEY ("PATIENT_ID") ENABLE,
     CONSTRAINT "PACIENT_CON" UNIQUE ("TELEFON_PACIENT") ENABLE
ALTER TABLE "PATIENT" ADD CONSTRAINT "PATIENT_CON3" FOREIGN KEY ("Employee_ID")
     REFERENCES "Dentist" ("Employee_ID") ON DELETE SET NULL ENABLE
Appointment
CREATE TABLE "Appointment"
(     "Appointment_ID" NUMBER,
     "Employee_ID" NUMBER CONSTRAINT "NN_Dentist_Appointment" NOT NULL ENABLE,
     "Patient_ID" NUMBER CONSTRAINT "NN_PATIENT_Appointment" NOT NULL ENABLE,
     "Who_Made" NUMBER,
     "Who_Changed" NUMBER,
     "Who_Canceled" NUMBER,
     "Content" VARCHAR2(1000),
     "DATE" DATE,
     CONSTRAINT "PK_Appointment" PRIMARY KEY ("Appointment_ID") ENABLE
ALTER TABLE "Appointment" ADD CONSTRAINT "Appointment_CON" FOREIGN KEY ("Patient_ID")
     REFERENCES "PATIENT" ("Patient_ID") ENABLE
ALTER TABLE "Appointment" ADD FOREIGN KEY ("Employee_ID")
     REFERENCES "Dentist" ("Employee_ID") ENABLE
ALTER TABLE "Appointment" ADD FOREIGN KEY ("Who_Made")
     REFERENCES "Employee" ("Employee_ID") ENABLE
ALTER TABLE "Appointment" ADD FOREIGN KEY ("Who_Changed")
     REFERENCES "Employee" ("Employee_ID") ENABLE
ALTER TABLE "Appointment" ADD FOREIGN KEY ("Who_Canceled")
     REFERENCES "Employee" ("Employee_ID") ENABLE
Dentist
CREATE TABLE "Dentist"
(     "Employee_ID" NUMBER,
"Qualifications" VARCHAR2(50),
CONSTRAINT "RB_VRAB_STOMATOLOG_PK" PRIMARY KEY ("Employee_ID") ENABLE
ALTER TABLE "Employee_ID" ADD CONSTRAINT "Dentist_CON" FOREIGN KEY ("Employee_ID")
REFERENCES "Employee" ("Employee_ID") ON DELETE CASCADE ENABLE
I'm trying to make an application in Oracle Application Express and I've tried making an SQL report using the following SQL query:
CREATE OR REPLACE FORCE VIEW "Appointment_REPORT" ("DOCTOR", "PATIENT", "Content", "Date") AS
select concat(concat(v.name,' '),v.surname) as doctor, concat(concat(pa.name_patient,' '),pa.surname_patient) as pactent, p.content, p.date
from Appointment p, Amployee v, Patient pa
where
v.employee_id=p.employee_id
and p.patient_id=pa.patient_id
The SQL works fine and gives me lovely results in my report. However, I don't know how to link the SQL to my actual Appointment table. Deleting, updating or creating new appointments through this view is impossible because I get the following error Unexpected error, unable to find item name at application or page level.
I understand how to make a form on the Appointment table but given how that table contains lots of primary keys (numbers) it's not preferable for the user to have to deal with that.
Can I have some help with linking the two and making it functional?
Thanks in advance.

AVOID using Reserved Words like "DATE" as column or table names!

Any table can have only ONE Primary Key.
Can I have some help with linking the two and to which "two" do you refer?
making it functional?Since you have told us what functionality is desired or expected,
I don't know what might be a solution.
