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!

ERROR MESSAGE

You have an error in your SQL syntax; check the manual that
corresponds to your MySQL server version for the right syntax to use
near '
CONSTRAINT FK FOREIGN KEY (fkordereditem) REFERENCES TheOrder(ordereditem) ' at line 6

You have multiple problems :

1. you forgot a comma after postcode INTEGER
   


2. 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).


3. 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)


4. 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
   


5. it seems you are trying to insert duplicates for some primary key values


6. you are referencing foreign keys with different data types then your column

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