Sample Data Model (Departments and Employees) produces bad SQL. Missing semi-colon, and bad BLOB insert.

[neilfernandez]

Although this is uncoupled from APEX, there are a few basic data models we have preloaded. Testing, and realized that some do not work. Here is one that is broken:

departments /insert 4
   name /nn
   location
   country
   employees /insert 14
      name /nn vc50
      email /lower
      cost center num
      date hired
      job vc255

view emp_v departments employees

This is a simple departments and employees table with a view and some fake rows.

Here is the script it generates:

-- create tables

create table departments (
    id          number default on null to_number(sys_guid(), 'XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX') 
                constraint departments_id_pk primary key,
    name        varchar2(255 char) not null,
    location    varchar2(4000 char),
    country     varchar2(4000 char)
);


create table employees (
    id               number default on null to_number(sys_guid(), 'XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX') 
                     constraint employees_id_pk primary key,
    department_id    number                     constraint employees_department_id_fk
                     references departments,
    name             varchar2(50 char) not null,
    email            varchar2(255 char),
    cost_center      number,
    the_start        date,
    job              varchar2(255 char),
    image            blob
);

-- table index
create index employees_i1 on employees (department_id);




-- triggers
create or replace trigger employees_biu
    before insert or update
    on employees
    for each row
begin
    :new.email := lower(:new.email);
end employees_biu;
/

You can see the that view here is missing a ; and if you try to run this whole script, it fails with Error at line 22/1: ORA-00936: missing expression

Also the inserts ALL fail with : ORA-01465: invalid hex number

This is due to the image column being a blob and trying to insert 'N/A' into it. BLOB columns rather should just get null.
