Hari Sankar Sivarama Subramaniyan updated HIVE-13290:
-----------------------------------------------------
    Description: 
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)  DISABLE NOVALIDATE
  ); 

CREATE TABLE vendor 
  ( 
     vendor_id INTEGER, 
     PRIMARY KEY (vendor_id)  DISABLE NOVALIDATE RELY
  ); 
{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. The RELY/NORELY 
keyword is also optional.
