plsql - Why will my PL/SQL Coding not work, when trying to create 5 tables and insert 5 samples into each table? -

duplicate column name, missing commas (every column , constraint definition should separated comma), primary key should not have underline: "primary_key" incorrect. phone_shipping_status table has invalid column name it's primary key , think should shipping_status_id. typo in shiping_status_id , should shipping_status_id, foreign keys phone_customer , phone_item table typed customer , item... , important thing order of tables definition according relations between them re-arranged order. don't think inserts have important issue, didn't check them. it's correct ddl code:
