I am creating a table within my database in Netbeans (Java DB).
I have created the database and I am connected to it.
This is my first and only table:

and the error I am receiving is this:

I am an amateur when it comes to databases and I have tried searching high and low to find what I'm doing wrong. I've tried:
- Changing the table name to all lower case, all capitals and how it is now too.
- Changing the primary key.
- Changing the column names.
- Changing the size of the column uid (which is fixed to 0 unless the data type is changed - I assume for obvious reasons this is correct anyway)
Where am I going wrong?
