I am having a hard time getting an output from a table.
Here is the table creation
CREATE OR REPLACE TYPE FULL_MAILING_ADDRESS AS OBJECT
( STREET VARCHAR2(80),
CITY VARCHAR2(80),
STATE CHAR(2),
ZIP VARCHAR2(10));
CREATE TABLE CUSTOMER
(
FULL_ADDRESS FULL_MAILING_ADDRESS
);
INSERT INTO CUSTOMER VALUES (FULL_MAILING_ADDRESS('55 SOUTH','ARLINGTON','VA','2222'));
when I do select on the table I don't get the values instead I get
[ORACLE.FULL_MAILING_ADDRESS]

I'm running the following SQLite workaround to add a primary key to a table that did not have one. I am getting a datatype mismatch on
INSERT INTO cities
SELECT id, name FROM old_cities;
However, the fields have exactly the same type. Is it possible that his happens due to running the queries from DbBrowser for SQLite?
CREATE table cities (
id INTEGER NOT NULL,
name TEXT NOT NULL
);
INSERT INTO cities (id, name)
VALUES ('pan', 'doul');
END TRANSACTION;
PRAGMA foreign_keys=off;
BEGIN TRANSACTION;
ALTER TABLE cities RENAME TO old_cities;
--CREATE TABLE cities (
-- id INTEGER NOT NULL PRIMARY KEY,
-- name TEXT NOT NULL
--);
CREATE TABLE cities (
id INTEGER NOT NULL,
name TEXT NOT NULL,
PRIMARY KEY (id)
);
SELECT * FROM old_cities;
INSERT INTO cities
SELECT id, name FROM old_cities;
DROP TABLE old_cities;
COMMIT;
You have defined the column id of the table cities to be INTEGER, but with this:
INSERT INTO cities (id, name) VALUES ('pan', 'doul');
you insert the string 'pan' as id.
SQLite does not do any type checking in this case and allows it.
Did you mean to insert 2 rows each having the names 'pan' and 'doul'?
If so, you should do something like:
INSERT INTO cities (id, name) VALUES (1, 'pan'), (2, 'doul');
Later you rename the table cities to old_cities and you recreate cities but you do something different: you define id as INTEGER and PRIMARY KEY.
This definition is the only one that forces type checking in SQLite.
So, when you try to insert the rows from old_cities to cities you get an error because 'pan' is not allowed in the column id as it is defined now.
I am trying to create a basic table using subtypes and insert some data into this in Oracle Express 11g.
My table is successfully created but i am having issues with inserting data.
The result of my insert statement always throws back an error 'SQL Error: ORA-00904: "BRANCH_PHONE": invalid identifier'.
The column which shows up in the error message is always the column which is at the end of the insert statement, despite the column existing in the table. I have tried the following code:
create type addressType as object(
street varchar2(20),
city varchar2(20),
postCode varchar2(8))
not final
/
create type branchType as object(
branchID int,
branch_address addressType,
branch_phone int(11))
not final
/
create table Branch of branchType(
constraint branch_pk primary key(branchID));
/
insert into Branch values (
branchID('2364'),
addressType('12 Rooster','Atlantis','A13 4UG'),
branch_phone('01316521311'));
I would really appreciate any ideas.
I made some changes, including changing the branch_phone to varchar2. A Phone number, while is "numbers" is not a data type of number. it is a string of characters. Also you were passing branchID as a string, but you are declaring it as a number, so changed that also. BranchID and branch_phone are primitive data types, so no constructor needed.
create type addressType as object(
street varchar2(20),
city varchar2(20),
postCode varchar2(8))

/

branchID int,
branch_address addressType,
branch_phone varchar2(11))
not final
/
create table Branch of branchType(
constraint branch_pk primary key(branchID));

insert into Branch values (
branchtype(2364,
addressType('12 Rooster','Atlantis','A13 4UG'),
'01316521311') )
I have three tables customer_cars, bookings, and replaced_parts ad below:
CREATE TABLE customer_cars(
pk_car_id NUMBER(11) NOT NULL,
car_plate_number VARCHAR2(15) NOT NULL
);
CREATE TABLE bookings(
pk_booking_id NUMBER(11),
fk_car_id NUMBER(11),
);
CREATE TABLE replaced_parts(
pk_parts_id VARCHAR2(25),
fk_booking_id NUMBER(11),
replaced_parts parts_varray_type
);
CREATE OR REPLACE TYPE parts_type AS OBJECT (
name VARCHAR2(25),
price NUMBER(10),
);
/
CREATE TYPE parts_varray_type AS
VARRAY(40) OF parts_type;
/
I am trying to get parts name from parts_varray_type of a car. All i have is car_plate_number. Using this plate number i want to find pk_car_id in customer_cars and then that pk_car_if id should match with fk_car_id in bookings to find bookings_id. Then the found booking id should match with fk_booking_id in replaced_parts to get the parts_name.
INSERT INTO customer_cars (pk_car_id, car_plate_number)
VALUES(200000,'5651L');
INSERT INTO bookings(pk_booking_id, fk_car_id)
VALUES(700000,200000);
INSERT INTO replaced_parts (pk_parts_id, fk_booking_id, replaced_parts)
VALUES(700000,600000,
parts_varray_type(
parts_type('CLUTCH', 2000)));
Above is the insert statements. Now using plate number '5651L' i want to display clutch , 2000 from parts parray type.
Something like:
SELECT..
FROM..(Usings joins or any other methods)
WHERE pk_car_id = '5651L';
It should display name and price from parts varray type.
I spend lot of time searching where i made the mistake but i was unable to find it when its going to insert the last record there is a error message showing "ORA-00936: missing expression" How to solve this please help me

It'll be great if someone can help me D:
(This is all based on my very limited knowledge of Oracle's object-relational technology. Some of it may be wrong, and there's likely a simpler way to do this.)
As I understand it, a REF must point to an actual row. You must create some data before you can create some data. Since there are so many circular references you'll have to go back later and update everything. But hopefully this is enough to at least get you started.
--Create some rows to reference.
insert into campusClub4(cid) values(1);
insert into department4(code) values('A');
--Insert regular columns first.
insert into student4(pid, firstName, lastName, dob, status)
values('10', 'alex', 'smith', to_date('31-MAY-1998', 'DD-MON-YYYY'), 'FRESH');
--Add references with an update.
update student4
set memberOf = (select ref(campusClub) from campusClub4 campusClub where cid = 1)
,major = (select ref(department) from department4 department where code = 'A')
where pid = '10';
--Verify data
select pid, firstname, lastname, dob, status, deref(memberOf), deref(major) from student4;
--This would be a simpler method, but it doesn't work and I don't understand why.
insert into student4(pid, firstName, lastName, dob, status)
values('10', 'alex', 'smith', to_date('31-MAY-1998', 'DD-MON-YYYY'), 'FRESH'
,(select ref(campusClub) from campusClub4 campusClub where cid = 1)
,(select ref(department) from department4 department where code = 'A')
);
But I strongly recommend that you NEVER DO THIS. Inserting data into a table should not be this difficult. Object Relational databases are probably a bad idea. And Oracle's implementation of it sucks. You'll get ORA-600 errors and "invalid" tables all over the place with this stuff (e.g. I just got an ORA-600 from cross joining campusClub4 and department4 with only one row in each). And nobody will know how to use your data.
