问题
I would really like to create a comment to a view with a short description of its purpose. Unfortunately it is not possible to create comments to views in oracle. This feature is only for tables, columns and materialized views available. I would like to know how you do describe your database views?
回答1:
Try:
comment on table <name> is 'text';
The command works on views. For example:
CREATE OR REPLACE VIEW MY_VW AS
SELECT 1 FROM DUAL;
COMMENT ON TABLE MY_VW IS 'Clever comment.';

Its possible to create a comment on VIEWs too :
COMMENT ON TABLE view_name ;
回答3:
Simply use :
Comment on table 'view Name' is ' Comment ...';
If use view in place of SQL , Oracle throws error invalid object category for COMMENT command".
Materialized View : we can simply comment using:
Command on Materialized view "View name" is 'Comment ...';
