ORA-00913: too many values Error (Even though I have checked my table and entries) - oracle10g

Here's is the table :
create table Student(
student_id char(6) primary key,
name varchar(10) not null,
department char(20),
grade char(6),
percentage smallint,
contact_no char(12),
address varchar(50)
);
This is what I'm inserting :
insert into Student
values ('ST-01','Zain','coe','A+',74,'9999777865','New Delhi');
Why ORA-00913: too many values error when I'm not inserting extra values ?

What is wrong with this Query ? PostgreSQL

I want to create 3 tables and join them with foreign keys. Unfortunately, it doesn't work and I have no idea where is a mistake.
CREATE TABLE Students (
Student_Id SERIAL PRIMARY KEY,
Name VARCHAR (20) NOT NULL,
Surname VARCHAR (30) NOT NULL,
Date_of_Birth DATE NOT NULL,
Phone INT NOT NULL UNIQUE,
Email VARCHAR(225) NOT NULL UNIQUE,
Course_Id INT
FOREIGN KEY (Course_Id) REFERENCES Course (Course_Id)
);
CREATE TABLE Course (
Course_Id SERIAL PRIMARY KEY,
Student_Id INT NOT NULL,
Teacher_Id INT NOT NULL,
Category VARCHAR (30) NOT NULL,
FOREIGN KEY (Student_Id) REFERENCES Students (Student_Id)
);
CREATE TABLE Teachers (
Teacher_Id SERIAL PRIMARY KEY,
Name VARCHAR (20) NOT NULL,
Surname VARCHAR (30) NOT NULL,
Phone INT NOT NULL UNIQUE,
Salary INT NOT NULL,
Course_Id INT NOT NULL,
FOREIGN KEY (Teacher_Id) REFERENCES Course (Teacher_Id)
);
I should create a Foreign Key to join all three tables.
I get this error every time: relation "course" does not exist
I can't find where is the mistake. Please help.

It appears like you are attempting to crate a many-to-many (M:M) between Students and Teachers with Course as the resolution table. You are close, however, your definition sets up bi-directional relationships. This is normally not necessary. Define Students and Teachers without the FK to Course. Then define Course with a FK to each.
create table students (
student_id serial primary key
, name varchar (20) not null
, surname varchar (30) not null
, date_of_birth date not null
, phone int not null unique
, email varchar(225) not null unique
);
create table teachers (
teacher_id serial primary key
, name varchar (20) not null
, surname varchar (30) not null
, phone int not null unique
, salary int not null
);
create table course (
course_id serial primary key
, student_id int not null
, teacher_id int not null
, category varchar (30) not null
, foreign key (student_id) references students (student_id)
, foreign key (teacher_id) references teachers (teacher_id)
, unique (student_id, teacher_id)
);
If you must define bi-directional FK in Students and Teachers then create the tables without the FK then use alter table after Course is defined to add the FK and make them DEFERRABLE INITIALLY DEFERRED. Necessary for eventual Inserts.
alter table teachers add column course_id int references course(course_id) deferrable initially deferred;
alter table students add column course_id int references course(course_id) deferrable initially deferred;

When I run this code a syntax error keeps appearing but I am unable to find where it would be

When I run this code, I receive a very vague syntax error: database: syntax error at or near "(". I am unable to find where this syntax error would be.

Thanks!

INT(10) is not valid datatype:
a_animal_cost INT(10)
There are other issues as well, you have to fix this.

You have a number of errors in your code. When running PostgreSQL only lists the first one, which in this case is the line a_animal_cost INT(10),. Integers are a fixed size so it is wrong to attempt to specify a size for it.
Also do not use char(1) for Yes ('Y') No ('N') fields. PostgreSQL has a native boolean data type for this purpose, so use it.
When deleting tables, you need to delete the lowest tables in the hierarchy first (foreign key etc).
Finally, you can chain multiple inserts as values together.
Putting all this together, I would recommend that you use something like this:
DROP TABLE IF EXISTS animal_adoption_history;
DROP TABLE IF EXISTS animal;
DROP TABLE IF EXISTS customer;

I get error as "duplicate key value violates unique constraint "

I'm working on a data warehouse. I have 4 table on public schema they are customer, product, addressee and orders
Then I created this tables on my olap schema
CREATE TABLE olap.time
(
idtime SERIAL NOT NULL PRIMARY KEY,
year integer,
month integer,
week integer,
day integer
);
CREATE TABLE olap.addressees
(
idaddressee integer PRIMARY KEY NOT NULL,
name varchar(40) NOT NULL,
zip char(6) NOT NULL,
address varchar(60) NOT NULL
);
CREATE TABLE olap.customers
(
idcustomer varchar(10) PRIMARY KEY ,
name varchar(40) NOT NULL,
city varchar(40) NOT NULL,
zip char(6) NOT NULL,
address varchar(40) NOT NULL,
email varchar(40),
phone varchar(16) NOT NULL,
regon char(9)
);
CREATE TABLE olap.fact
(
idtime integer NOT NULL,
idaddressee integer NOT NULL,
idcustomer varchar(10) NOT NULL,
idfact integer NOT NULL,
price numeric(7,2),
PRIMARY KEY (idtime, idaddressee, idcustomer),
FOREIGN KEY (idaddressee) REFERENCES olap.addressees(idaddressee),
FOREIGN KEY (idcustomer) REFERENCES olap.customers(idcustomer),
FOREIGN KEY (idtime) REFERENCES olap.time(idtime)
);
After the creating tables I run these queries
INSERT INTO olap.time (year, month, week, day)
SELECT date_part('year', date), date_part('month', date), date_part('week', date), date_part('day', date)
FROM public.orders
GROUP BY public.orders.date
ORDER BY public.orders.date;
INSERT INTO olap.addressees(idaddressee, name, zip, address)
SELECT idaddressee, name, zip, address
FROM public.addressee;
INSERT INTO olap.customers (idcustomer, name, city, zip, address, email, phone, regon)
SELECT idcustomer, name, city, zip, address, email, phone, regon
FROM public.customer;
And then I try to do these set of query
INSERT INTO olap.fact (idtime, idaddressee, idcustomer, idfact, price)
SELECT olap.time.idtime, olap.addressees.idaddressee, olap.customers.idcustomer, COUNT(*), public.orders.price
FROM (((public.orders
INNER JOIN olap.time ON (date_part('year', public.orders.date) = olap.time.year AND date_part('month', public.orders.date) = olap.time.month AND date_part('week', public.orders.date) = olap.time.week) AND date_part('day', public.orders.date) = olap.time.day)
INNER JOIN olap.addressees ON public.orders.idaddressee = olap.addressees.idaddressee)
INNER JOIN olap.customers ON public.orders.idcustomer = olap.customers.idcustomer)
GROUP BY olap.time.idtime, olap.addressees.idaddressee, olap.customers.idcustomer, public.orders.price;
After running last set of queries I got error
ERROR: syntax error at or near "duplicate"
LINE 1: duplicate key value violates unique constraint"
What can the problem be? Thanks in advance

How do you create the table structure in PostgreSQL to make a many-to-many relationship

my example so far I would like to know how to create a many to many relationship with these.
CREATE TABLE accounts (
id SERIAL,
first_name VARCHAR(50),
last_name VARCHAR (50),
username VARCHAR (50),
password VARCHAR (500),
account_Type VARCHAR (10),
bday VARCHAR (50),
PRIMARY KEY(id)
);
CREATE TABLE bank_account(
id SERIAL,
account_number INTEGER PRIMARY KEY,
account_balance INTEGER
);

you can create a table like this one:
CREATE TABLE bank_account_accounts(
id serial primary key,
accounts_id integer,
bank_account_id integer
);

Hello I'm pretty new to PostgreSQL so I trying to create a one to one relationship between the tables account and bank_account

I tried using a foreign key, but it still shows them as being separate and not connected is there something I'm missing here, my goal was to originally link the persons name to the account_balance.
CREATE TABLE accounts (
id SERIAL,
first_name VARCHAR(50),
last_name VARCHAR (50),
username VARCHAR (50),
password VARCHAR (500),
account_Type VARCHAR (10),
bday VARCHAR (50),
PRIMARY KEY(id)
);
CREATE TABLE bank_account(
id SERIAL,
account_number INTEGER PRIMARY KEY,
account_balance INTEGER,
CONSTRAINT bank_users
FOREIGN KEY (id)
REFERENCES accounts(id)
ON DELETE CASCADE
);
INSERT INTO accounts (
first_name,
last_name,
username,
password,
account_Type,
bday)
VALUES ('bob', 'john', 'bob#gmail.com', crypt('bob1',gen_salt('bf')),'Manager', '01/01/1985'),
('Tom', 'lin', 'tom#gmail.com', 'tom1', 'Manager', '5/23/1990');
INSERT INTO bank_account(
account_number,
account_balance)
VALUES ('1234', '50000'),('4332', '100000');
