SQL - Syntax Error (Problems with PK and FK) - sql

Question

I a want to fill a DB with SQL, but I get syntax errors. I think the problem is in PK and FK. Can you please take a look, what am I doing wrong in my approach.
Thank you very much!

Answer 1

You have multiple problems :
you forgot a comma after postcode INTEGER
You forgot to specify the length for some VARCHAR column definitions (this is mandatory, if you don't want to specify a length use VARCHAR(MAX).
column order in some INSERT statements does not match the table definition (you need to respect the order, or specify the column names in the INSERT statement)
you are trying to set foreign keys that references non primary key, if you want to do this you need to define referenced columns as UNIQUE
it seems you are trying to insert duplicates for some primary key values
you are referencing foreign keys with different data types then your column

Answer 2

I found the error. The assigned types have not been the same for the FK and for the referenced attribute.
