I got rid of the Drop tables at the top just to show the main code. Any help would be greatly appreciated!

Here's the Errors:

Error at Command Line:58 Column:6 Error report: SQL Error: ORA-02253: constraint specification not allowed here

Error at Command Line:209 Column:68 Error report: SQL Error: ORA-00942: table or view does not exist 00942. 00000 - "table or view does not exist"

Error at Command Line:199 Column:71 Error report: SQL Error: ORA-00942: table or view does not exist 00942. 00000 - "table or view does not exist"

Error at Command Line:186 Column:69 Error report: SQL Error: ORA-00942: table or view does not exist 00942. 00000 - "table or view does not exist"

Error at Command Line:169 Column:78 Error report: SQL Error: ORA-02270: no matching unique or primary key for this column-list 02270. 00000 - "no matching unique or primary key for this column.

All the tables have the same TABLE OR VIEW DOES NOT EXIST error.

Answer 1

You need to define the referenced tables before the tables referencing them.
For example, define dealer before bike (because bike references dealer).

If you've got a circular situation where A references B and visa versa, wrap the two table create statements in a transaction with a leading BEGIN and trailing COMMIT . Note that doing this is usual and should only be done after careful consideration and if absolutely necessary.

I think there's something fundamentally wrong with your table design too; the dealer table has bikeno as part of its primary key. That seems completely wrong to me - bikeno shouldn't be in the dealer table at all, let alone be part of its key!

And this is a little insane:

CREATE TABLE customer (
  CustNo         NUMBER(8),
  ...
  PRIMARY KEY(CustNo),  
  FOREIGN KEY(CustNo)
  REFERENCES customer (CustNo)
);

Huh? I've never seen this before - a table referencing itself!?
