Hi, Can you point me to any pages that explain the difference between using, say CHAR(8) vs VARCHAR(8) as the primary key for a table? Is there any impact on the database in terms of:
- Speed of indexed retrieval - Speed of join from a referencing table - Storage (I presume VARHAR(8) would have a slight edge, in general) - Any other issue Regards, -- Raj -- Raj Mathur r...@kandalaya.org http://kandalaya.org/ GPG: 78D4 FC67 367F 40E2 0DD5 0FEF C968 D0EF CC68 D17F PsyTrance & Chill: http://schizoid.in/ || It is the mind that moves -- Sent via pgsql-sql mailing list (pgsql-sql@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-sql
