I keep getting a missing right or left parenthesis error when I try to create my tables with a foreign key, but when I remove the foreign key my code has no problem creating the tables. I need the code to run with the foreign keys.

The degree table is the only table where I don't get an error.
Should I use an alter table instead after I create all the tables or is there another way to solve my problem?
edit: updated code
I think your most immediate issue is with the Department table not having a comma between the two CONSTRAINT clauses. You might also run into issues with your Position table's CONSTRAINT clause referencing the Position table instead of the Employee table, although honestly I don't think you need that relationship defined at all since the Employee table already has a foreign key constraint with Position. And like what was stated earlier, your table definitions aren't in the right order so you have some tables referencing other tables before those others are created.
Give this a shot to see if the syntax works. I've added the column definition for the foreign key in Position, put parentheses around the foreign key column name in the CONSTRAINT clause, and removed the space between Department and the left paren in the CONSTRAINT clause. If this script works, make the same changes to your other table defs.
CREATE TABLE Department(
Dept_Name varchar(255) Primary Key, --primary key
Dept_Phone_Num numeric(35) not null
);
CREATE TABLE Position(
Position_Name varchar(255) not null Primary Key, --primary key
Position_Salary decimal(10, 2) not null,
Employee_num numeric(35) not null,
Dept_Name varchar(255) not null,
CONSTRAINT fk_Dept_Name FOREIGN KEY (Dept_Name) REFERENCES Department(Dept_Name) --foreign key
);
In this database I have created 7 tables but in my last 2 tables, the billing and the product_billing table, I need to add foreign keys, I have used the method below but getting two different errors on each table when executing.
This is my code:

I got these errors and it will not process- I think I have problem with my foreign key but I am not sure.
Msg 1769, Level 16, State 1, Line 40
Foreign key 'EmpOrdFK' references invalid column 'EmployeeID' in referencing table 'ORDER'.
Msg 1750, Level 16, State 0, Line 40
Could not create constraint or index. See previous errors.
There's no column EmployeeID in the ORDER table, so:
EmpOrdFK FOREIGN KEY(EmployeeID) REFERENCES EMPLOYEE(EmployeeID)
which says, create a foreign key in which Order.EmployeeId references Employee.EmployeeId, can't work.
Did you want to add an EmployeeId column to Order?
(There's also no CustomerId in Order, so the next line
CONSTRAINT CustOrdFK FOREIGN KEY (CustomerID)
would have failed too, except it never got to run because of the first error.)
You probably want to add EmployeeId and CustomerId to the Order table.
When you are mapping foreign key from Order table to Employee table, you have to map on common column in both tables. If you look at order table, which is missing employeeId in
that table.
And also don't call it as ORDER table. ORDER is reserved keyword in SQL server.

Attached is my attempt at creating a database for the following entity relationship diagram. But I keep getting the following error:
"SQL0538N FOREIGN KEY "ADVISOR_STUDENT" does not conform to the
description of the parent key of table or nickname "KISHANPA.STUDENT".
SQLSTATE=42830"
for these 4 tables: advisor, prereq, teaches, takes. The rest of the tables seem to work fine. It would be greatly appreciated if someone can guide me int eh right direction. Thanks

Your problem is on your key for student. You must have the same column to join tabes whith FK. Modify you table student like this :
create table student (sid char(9) not null, name varchar(30) not null, tot_cred smallint, dept_name varchar(30) not null, constraint student_key primary key (sid), constraint student_dept foreign key(dept_name) references department on delete no action);
The docs say this:
A foreign key references a primary key or a unique key in the same or
another table. A foreign key assignment indicates that referential
integrity is to be maintained according to the specified referential
constraints.
Your "advisor_student" references "sid", but that is not the primary key. You would need to include the department or change the design.
Your primary keys don't match your schema diagram for several tables.
Instructor, student, and course all have dept_name in the primary key in your DDL, but according to the Schema diagram, and logically as well, this field should not be a part of the primary key for any of those tables. In addition, the primary key of section does not match the Schema diagram. It should be (course_id, sec_id, semester, year) You have a lot of extra fields in there. That will cause problems with the foreign key constraints on teaches and takes.
Finally, the time_slot file both in the schema, and in the DDL have what I would call a questionable, given no other input, primary key. Should just be time_slot_id to my mind, then you can build a foreign key from section to time_slot as well.
