INSERT statements gives me different errors - sql

Question

I'm trying to run a file which contains INSERT statements. The statements will either give me an not enough values error or unique constraint error.
Below is my create table statement:
CREATE TABLE PART
(PNum VARCHAR(25) NOT NULL,
PName VARCHAR(75) NOT NULL,
PUnitPrice NUMBER(7,2) NOT NULL,
ComponentOf VARCHAR(25),
CONSTRAINT PART_PKEY PRIMARY KEY(PNum),
CONSTRAINT PART_FKEY FOREIGN KEY(ComponentOf)
REFERENCES PART(PNum)
};
CREATE TABLE MANUFACTURER
(MName VARCHAR(50) NOT NULL,
MAddress VARCHAR(100) NOT NULL,
MPhone VARCHAR(25) NOT NULL,
CONSTRAINT MANUFACTURER_PKEY PRIMARY KEY(MName),
);
CREATE TABLE PART-MANUFACTURED
(MDate DATE,not null
PNum VARCHAR(25) NOT NULL,
MName VARCHAR(50) NOT NULL,
Quantity NUMBER(10) NOT NULL,
CONSTRAINT PART-MANUFACTURED_PKEY PRIMARY KEY(MName,PNum,MDate),
CONSTRAINT PART-MANUFACTURED_FKEY1 FOREIGN KEY(PNum)
REFERENCES PART(PNum),
CONSTRAINT PART-MANUFACTURED_FKEY2 FOREIGN KEY(MName)
REFERENCES MANUFACTURER(MName)
);
CREATE TABLE CUSTOMER
(CNum VARCHAR(25) NOT NULL,
CName VARCHAR(75) NOT NULL,
CType VARCHAR(20) NOT NULL,
CONSTRAINT CUSTOMER_PKEY PRIMARY KEY(CNum),
CONSTRAINT CHECK_CType
CHECK(CType IN (‘INDIVIDUAL,’INSTITUITION’))
);
CREATE TABLE ORDERS
(CNum VARCHAR(25) NOT NULL,
PNum VARCHAR(25) NOT NULL,
OrderDate DATE NOT NULL,
OrderQuantity NUMBER(7,2) NOT NULL,
CONSTRAINT ORDERS_PKEY PRIMARY KEY(CNum,PNum,OrderDate),
CONSTRAINT ORDERS_FKEY1 FOREIGN KEY(CNum)
REFERENCES CUSTOMER(CNum),
CONSTRAINT ORDERS_FKEY2 FOREIGN KEY(PNum)
REFERENCES PART(PNum)
);
Below is the statement that gives me the not enough values error:
INSERT INTO PART
VALUES('S001','System-Economy',1100,null);
INSERT INTO PART
VALUES('M001','Monitor-17 inch',250,'S001');
For the unique constraints error, I believe i have to insert the data in order of their primary and referencing keys right?
So what do I need to change in order for the the insert statements to work?

Answer 1

I dont see any error on Insert. The problem is with your create table. Plenty to correct. Try this
CREATE TABLE PART ( PNUM VARCHAR ( 25 ) NOT NULL,
PNAME VARCHAR ( 75 ) NOT NULL,
PUNITPRICE NUMBER ( 7, 2 ) NOT NULL,
COMPONENTOF VARCHAR ( 25 ),
CONSTRAINT PART_PKEY PRIMARY KEY ( PNUM ),
CONSTRAINT PART_FKEY FOREIGN KEY
( COMPONENTOF )
REFERENCES PART ( PNUM ) );
CREATE TABLE MANUFACTURER ( MNAME VARCHAR ( 50 ) NOT NULL,
MADDRESS VARCHAR ( 100 ) NOT NULL,
MPHONE VARCHAR ( 25 ) NOT NULL,
CONSTRAINT MANUFACTURER_PKEY PRIMARY KEY ( MNAME ) );
CREATE TABLE PART_MANUFACTURED ( MDATE DATE NOT NULL,
PNUM VARCHAR ( 25 ) NOT NULL,
MNAME VARCHAR ( 50 ) NOT NULL,
QUANTITY NUMBER ( 10 ) NOT NULL,
CONSTRAINT PART_MANUFACTURED_PKEY PRIMARY KEY
( MNAME, PNUM, MDATE ),
CONSTRAINT PART_MANUFACTURED_FKEY1 FOREIGN KEY
( PNUM )
REFERENCES PART ( PNUM ),
CONSTRAINT PART_MANUFACTURED_FKEY2 FOREIGN KEY
( MNAME )
REFERENCES MANUFACTURER ( MNAME ) );
CREATE TABLE CUSTOMER ( CNUM VARCHAR ( 25 ) NOT NULL,
CNAME VARCHAR ( 75 ) NOT NULL,
CTYPE VARCHAR ( 20 ) NOT NULL,
CONSTRAINT CUSTOMER_PKEY PRIMARY KEY ( CNUM ),
CONSTRAINT CHECK_CTYPE CHECK
( CTYPE IN ('INDIVIDUAL', 'INSTITUITION') ) );
CREATE TABLE ORDERS ( CNUM VARCHAR ( 25 ) NOT NULL,
PNUM VARCHAR ( 25 ) NOT NULL,
ORDERDATE DATE NOT NULL,
ORDERQUANTITY NUMBER ( 7, 2 ) NOT NULL,
CONSTRAINT ORDERS_PKEY PRIMARY KEY
( CNUM, PNUM, ORDERDATE ),
CONSTRAINT ORDERS_FKEY1 FOREIGN KEY
( CNUM )
REFERENCES CUSTOMER ( CNUM ),
CONSTRAINT ORDERS_FKEY2 FOREIGN KEY
( PNUM )
REFERENCES PART ( PNUM ) );
INSERT INTO
PART
VALUES
( 'S001',
'System-Economy',
1100,
NULL );
INSERT INTO
PART
VALUES
( 'M001',
'Monitor-17 inch',
250,
'S001' );
