could someone have a look at this for me, I can't seem to find why it is not working.

You missed a comma! This should work...

I get the error message:

How do I solve this?
Thanks.
You missed the pID column in student table. Try this:
CREATE TABLE Parent (
pID int IDENTITY(1,1) PRIMARY KEY,
FirstName varchar(50) NOT NULL,
LastName varchar(50) NOT NULL,
Email varchar(50) NOT NULL,
Address varchar(50) NOT NULL,
PersonalNumber int NOT NULL,
Phone varchar(50)
);
CREATE TABLE Student(

PersonalNumber int NOT NULL,
Phone varchar(50),
pID int,
FOREIGN KEY (pID) REFERENCES Parent(pID)
);
I have a problem with my first insert statement. I have searched online and nothing seems to help my understanding of this problem or how to fix it. When I execute the insert statement it gives me the message:
Error converting data type varchar to numeric.

I think there are a few different things going on here. First of all, you have a line that reads drop TABLE BOOKS before the insert, which will remove the table from the registry before you can add any rows to it.
Secondly, the numerics you're trying to insert are surrounded by quotes and SQL doesn't do very well with implicit conversions to begin with. Your ISBN should probably be a VARCHAR since it contains a leading 0, which will be dropped in the event it actually converts. So #marc_s is right, drop the quotes from all your numeric values to be inserted; this includes ISBN (currently), page number, and price.
I believe the error actually refers to what you have entered in the price field, which is $8.30. A numeric doesn't know how to read $ in SQL. Also, there is a data type that coners such needs called money. Drop the $ and change the data type of the price column to money and you should be OK.
Hope this helps.

I am getting this error message for the below code, however, can not see where the error is referring to. I thought that parenthesis referred to semicolons and commas. I assume there is something I am missing, any direction would be greatly appreciated.

I've spent a while trying to firgure it but but I can't see anything that would be causing this error. I'm thinking maybe something to do with the "Unique" statement.

Loan references Item, but you create Loan before you create Item. Create the Item table first.
