The Orders table is working but the Order_Items table is not working show error ORA_00903. I had change many other names, but it still show the error ORA-00903: invalid table name.
Your foreign key constraint is incorrect:
CONSTRAINT ITE_ORD_FK FOREIGN KEY(ORDER_NO)
REFERENCES ORDER(ORDER_NO)
^
You have named the referenced table ORDER instead of ORDERS.

Assuming this is the order you're creating your tables, this is likely your problem:
CREATE TABLE Store (
...
CONSTRAINT Manager_FK FOREIGN KEY (Manager_ID)
REFERENCES Manager (Manager_ID)
...
You're referencing a table in your table definition that doesn't exist yet.
Here is a logical model that I have.
Below are table structures and their constraints
Doctor
CREATE TABLE doctor (
doctor_id NUMBER(4) NOT NULL,
doctor_title VARCHAR2(2) NOT NULL,
doctor_fname VARCHAR2(50),
doctor_lname VARCHAR2(50),
doctor_phone CHAR(10) NOT NULL
);
ALTER TABLE doctor ADD CONSTRAINT doctor_pk PRIMARY KEY ( doctor_id );
Procedure
CREATE TABLE procedure (
proc_code NUMBER(5) NOT NULL,
proc_name VARCHAR2(100) NOT NULL,
proc_description VARCHAR2(300) NOT NULL,
proc_time NUMBER(3) NOT NULL,
proc_std_cost NUMBER(7, 2) NOT NULL
);
ALTER TABLE procedure ADD CONSTRAINT procedure_pk PRIMARY KEY ( proc_code );
ALTER TABLE procedure ADD CONSTRAINT proc_name_unq UNIQUE ( proc_name );
Admission
CREATE TABLE admission (
adm_no NUMBER(6) NOT NULL,
adm_date_time DATE NOT NULL,
adm_discharge DATE,
patient_id NUMBER(6) NOT NULL,
doctor_id NUMBER(4) NOT NULL
);
ALTER TABLE admission ADD CONSTRAINT admission_pk PRIMARY KEY ( adm_no ); --surrogate key
ALTER TABLE admission ADD CONSTRAINT admission_nk UNIQUE ( patient_id,
adm_date_time );
Admission Procedure
CREATE TABLE adm_prc (
adprc_no NUMBER(7) NOT NULL,
adprc_date_time DATE NOT NULL,
adprc_pat_cost NUMBER(7, 2) NOT NULL,
adprc_items_cost NUMBER(6, 2) NOT NULL,
adm_no NUMBER(6) NOT NULL,
proc_code NUMBER(5) NOT NULL,
request_dr_id NUMBER(4) NOT NULL,
perform_dr_id NUMBER(4)
);
ALTER TABLE adm_prc ADD CONSTRAINT adm_prc_pk PRIMARY KEY ( adprc_no ); --surrogate key
ALTER TABLE adm_prc ADD CONSTRAINT adm_prc_nk UNIQUE ( adprc_date_time,
adm_no );
ALTER TABLE adm_prc
ADD CONSTRAINT admission_admprc FOREIGN KEY ( adm_no )
REFERENCES admission ( adm_no );
ALTER TABLE adm_prc
ADD CONSTRAINT doctor_performadmprc FOREIGN KEY ( perform_dr_id )
REFERENCES doctor ( doctor_id );
ALTER TABLE adm_prc
ADD CONSTRAINT doctor_requestadmprc FOREIGN KEY ( request_dr_id )
REFERENCES doctor ( doctor_id );
Item Treatment
CREATE TABLE item_treatment (
adprc_no NUMBER(7) NOT NULL,
item_code CHAR(5) NOT NULL,
it_qty_used NUMBER(2) NOT NULL,
it_item_total_cost NUMBER(8, 2) NOT NULL
);
ALTER TABLE item_treatment
ADD CONSTRAINT item_treatment_pk PRIMARY KEY ( adprc_no,item_code);
ALTER TABLE item_treatment
ADD CONSTRAINT admprc_itemtreatment FOREIGN KEY ( adprc_no )
REFERENCES adm_prc ( adprc_no );
ALTER TABLE item_treatment
ADD CONSTRAINT admprc_itemtreatment FOREIGN KEY ( adprc_no )
REFERENCES adm_prc ( adprc_no );
ALTER TABLE item_treatment
ADD CONSTRAINT item_itemtreatment FOREIGN KEY ( item_code )
REFERENCES item ( item_code );
In a fictitious hospital, every time an admission procedure is completed for a patient admission, the lead doctor who performed the procedure is recorded under the perform_dr_id in adm_prc table. Even if a team of doctors perform the procedure, only the lead doctor is recorded.
The hospital now wishes to record all the doctors who performed in the admission procedure including an Ancillary doctor (assisting doctor).
I have altered the adm_prc table to include ancillary doctors
ALTER TABLE ADM_PRC ADD ANCILLARY_DR_ID NUMBER(4);
ALTER TABLE ADM_PRC
ADD CONSTRAINT DOCTOR_PERFORM_ANCILLARY FOREIGN KEY ( ANCILLARY_DR_ID )
REFERENCES DOCTOR ( DOCTOR_ID );
I need to change the structure of the database is such a way that, there should be multiple records for the same admission procedure as there can be many doctors assisting in a single admission procedure. For example, I should be able to insert the following records in adm_prc table
adprc_no adprc_date_time adprc_pat_cost adprc_items_cost adm_no proc_code
request_dr_id perform_dr_id ancillary_dr_id
-----------------------------------------------------------------------------------------------------------------------------
1 14/03/2019 100 100 1234 1234
10 10 12
1 14/03/2019 100 100 1234 1234
10 10 13
However, this violates primary key constraint adm_prc_pk
I'm stuck at this point and unable to proceed further. Would appreciate if someone could point me in the right direction.
You should create a new satellite table (say ADM_PRC_DR_DTLS) to hold adprc_no and corresponding dr_id details.
adprc_no of ADM_PRC_DR_DTLS would refer to the ADM_PRC's adprc_no as a Foreign Key.
I have to write a query with the following criteria:
Write a query to list the title and artist of ONLY the items that have been ordered. Only list each title once.
Here are the CREATE tables that were made that cannot be changed.
CREATE TABLE artists
(
artist_id INT NOT NULL,
artist_name VARCHAR(30),
CONSTRAINT artist_pk PRIMARY KEY (artist_id)
);
CREATE TABLE items
(
item_id INT NOT NULL,
title VARCHAR(50) NOT NULL,
artist_id INT NOT NULL,
unit_price DECIMAL(9,2) NOT NULL,
CONSTRAINT items_pk PRIMARY KEY (item_id),
CONSTRAINT items_fk_artists
FOREIGN KEY (artist_id) REFERENCES artists (artist_id)
);
CREATE TABLE orders
(
order_id INT NOT NULL,
customer_id INT NOT NULL,
order_date DATE NOT NULL,
shipped_date DATE,
employee_id INT,
CONSTRAINT orders_pk PRIMARY KEY (order_id),
CONSTRAINT orders_fk_customers
FOREIGN KEY (customer_id) REFERENCES customers (customer_id),
CONSTRAINT orders_fk_employees
FOREIGN KEY (employee_id) REFERENCES employees (employee_id)
);
Here is what I have done for my script.
SELECT
items.title, artists.artist_name, orders.order_date
FROM
items
JOIN
orders
JOIN
artists;
Please let me know how I can consolidate.
You should say the structures of tables with respect to keys between tables.

I have Assignment due in which i'm stuck on a question.
Add a “Sales Detail” table to your database. This table is related to the Orders and Products tables. It shows the product and quantity ordered at least (add other fields if you wish but explain why you added them on your paper).
There is no description of this table on the diagram provided. Use your best database design skills here!
Create Table SalesDetail

SaleDetailID int,
ProductID char(5),
ManufactureID char(3) not null,
OrderNo int,

REFERENCES Products(ProductID)
My Error is I can not get it to link SalesDetail table to Products table.

The table Products has a composite key (ManufactureID, ProductID), so you cannot uniquely identify a product by just the ProductId. Therefore you have to create a composite foreign key that references to both ManufactureId and ProductID:
Alter Table SalesDetail
Add FOREIGN KEY (ManufactureId, ProductID)
REFERENCES Products(ManufactureID, ProductID)
ProductID is not a primary key like the error says. In your code
PRIMARY KEY(ManufactureID, ProductID)
This creates a primary key that both of those columns combined.
The primary key for Products is (ManufactureID, ProductID). So the SalesDetail table should contain both these columns, and both should be part of the foreign key constraint:
Alter Table SalesDetail
Add FOREIGN KEY (ManufactureID, ProductID)
REFERENCES Products(ManufactureID, ProductID)
