error: value larger than specified precision allowed for this column - sql

Question

I am creating tables based on the SQL Developer, however, got couple problems from my code:
My table can be established one by one, but cannot run as a whole and get error:
ORA-00922: missing or invalid option
When I am trying to insert values, get the error:
ORA-01438: value larger than specified precision allowed for this column
I have no idea about how these two error come from and everything look like fine on my code.
create table FACULTY (
faculty_id VARCHAR(25),
fac_name VARCHAR(25),
office VARCHAR(25),
salary NUMBER(9,2),
primary key (faculty_id)
)
create table student (
student_id VARCHAR(25),
std_name VARCHAR(25),
home_phone CHAR(12),
total_credits NUMBER,
gpa NUMBER(1,2),
advisor_id VARCHAR(25),
PRIMARY KEY (student_id),
foreign key (advisor_id) REFERENCES FACULTY (faculty_id)
)
INSERT INTO student table, I have already insert values successfully for FACULTY table;
insert into student
values('111111111', 'Marcus', '21-4748363', 0, 3.11, '90421');
For 1st question:
Error report -
ORA-00922: missing or invalid option
00922. 00000 - "missing or invalid option"
For 2nd question:
Error starting at line : 40 in command -
insert into student
values('111111111', 'Marcus', '21-4748363', 0, 3.11, '90421')
Error report -
ORA-01438: value larger than specified precision allowed for this column

Answer 1

For 1st question
Use semicolon ; after the first table definition.
For 2nd question
You should define your table like this:
create table student (
student_id VARCHAR(25),
std_name VARCHAR(25),
home_phone CHAR(12),
total_credits NUMBER,
gpa NUMBER(3,2),
advisor_id VARCHAR(25),
PRIMARY KEY (student_id),
foreign key (advisor_id) REFERENCES FACULTY (faculty_id)
)
For gpa column it should be NUMBER(3,2) instead of NUMBER(1,2) to support 3.11 Value.
