Hi,
In C the best practice is to use #define for constants. In C++ you have 'const', in Java 'static final'. Unfortunately the 'named constant' concept doesn't exist in SQL. I think that's a mistake. I suggest to support CREATE CONSTANT ... VALUE ... and DROP CONSTANT ..., example: CREATE CONSTANT STATE_ACTIVE VALUE 'active'.
of course you mean: CREATE CONSTANT state_active TEXT VALUE 'active'; ? ;) interesting idea, would that mean PG complaints on queries SELECT state_active FROM sometable ... because state_active is already defined as constant? What about local session variables? Usefull as well... I think this is really a big effort :-) Greets Tino -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
