Subj:   Nulls in a composite Primary Key deployed as a Primary Index
 
From:   Anomy Anom

A proposed data model for multiple new DW base tables allows nulls in some of the columns involved in multiple 4-8 column composite primary keys (because the data isn't 100% available from the source systems). This may or may not survive our modeling process, but I'd welcome any feedback on deploying such a key as a primary index on Teradata.
