cqd ALLOW_NULLABLE_UNIQUE_KEY_CONSTRAINT ‘ON’;
then create table with nullable pkey col. only one null value is allowed. *From:* Eric Owhadi [mailto:[email protected]] *Sent:* Tuesday, February 2, 2016 11:27 AM *To:* [email protected] *Subject:* nullable primary key index column? Dear Trafodioneers, I am wondering if it is possible to use a composite primary key with the first column making up the primary key composite being nullable? If yes, is there any restriction, like only one row can be null for that nullable column? Thanks in advance for the help, Eric
