> SUPPORT for the following statements
> {code}
> CREATE TABLE product 
>   ( 
>      product_id        INTEGER, 
>      product_vendor_id INTEGER, 
>      PRIMARY KEY (product_id), 
>      CONSTRAINT product_fk_1 FOREIGN KEY (product_vendor_id) REFERENCES vendor(vendor_id) 
>   ); 
> CREATE TABLE vendor 
>   ( 
>      vendor_id INTEGER, 
>      PRIMARY KEY (vendor_id) 
>   ); 
> {code}
> In the above syntax, [CONSTRAINT constraint-Name] is optional. If this is not specified by the user, we will use system generated constraint name. For the purpose of simplicity, we will allow  CONSTRAINT option for foreign keys and not primary key since there is only one primary key per table.
