"ORA-01733: virtual column not allowed here" when inserting into a view - sql

Question

I created a view called "view_employee" like this:
CREATE VIEW view_employee AS
SELECT employee.surname || ', ' || employee.name AS comp_name, employee.sex, sections.name AS section_name, employee_age
FROM sections, employee WHERE employee.section = sections.sect_code;
And I would like to insert data into the table using the view, like this:
INSERT INTO view_employee VALUES ('Doe, John', 'm', 'Marketing', 34);
Here are the tables' columns and constraints:
create table sections(
sect_code number(2),
name varchar2(20),
income number(5,2)
constraint CK_sections_income check (income>=0),
constraint PK_sections primary key (sect_code)
);
create table staff(
ident number(5),
document char(8),
sex char(1)
constraint CK_staff_sex check (sex in ('f','m')),
surname varchar2(20),
name varchar2(20),
address varchar2(30),
section number(2) not null,
age number(2)
constraint CK_staff_age check (age>=0),
marital_status char(10)
constraint CK_employee_marital_status check (marital_status in
('married','divorced','single','widower')),
joindate date,
constraint PK_employee primary key (ident),
constraint FK_employee_section
foreign key (section)
references sections(sect_code),
constraint UQ_staff_document
unique(document)
);
The error message I get when attempting to insert is the following:
Error starting at Command Line: 1 Column : 1
Error report -
SQL Error: ORA-01733: virtual column not allowed here
01733. 00000 - "virtual column not allowed here"

How could I insert those values into the table using the view? Thanks in advance.

Answer 1

A view must not contain any of the following constructs. So, it can be updateable.
A set operator
A DISTINCT operator
An aggregate or analytic function
A GROUP BY, ORDER BY, MODEL, CONNECT BY, or START WITH clause
A collection expression in a SELECT list
A subquery in a SELECT list
A subquery designated WITH READ ONLY
Joins, with some exceptions, as documented in Oracle Database
Administrator's Guide.
