The request in this example specifies neither a primary index nor a primary key. Assuming that the DBS Control parameter PrimaryIndexDefault is set to D or P, Vantage maps the first unique column, column_2 , to a UPI, which cannot be null.
CREATE TABLE good_7 ( column_1 INTEGER, column_2 INTEGER NOT NULL UNIQUE, column_3 INTEGER NOT NULL UNIQUE);
This request defaults to the following definition.
CREATE TABLE good_7 ( column_1 INTEGER, column_2 INTEGER NOT NULL UNIQUE, column_3 INTEGER NOT NULL UNIQUE) UNIQUE PRIMARY INDEX (column_2);
