we can use "CREATE OR REPLACE" IN VIEWS,PROCEDURE,TRIGGER, FUNCTION they all are objects, yet TABLES are also objects but we cannot use REPLACE while table creation?
i will be very thankful.

Yes ... that is true ... probably because there are options associated with the 'drop table' statement.

DROP PROCEDURE does NOT have options. DROP VIEW does NOT have options.

An option is an 'option' as defined in the literature. Please read the documentation for the Oracle database.

May I suggest that you just ACCEPT that 'table' requires two commands, a 'drop' and a 'create', and that a 'procedure' can be handled with a single 'create or replace'. Tables contain data, procedures are self-contained.
