Add a Comment to a View

Oracle Database Tips by Burleson Consulting

August 31, 2015

Question: I know that I can add a comment to a table, but I want to add a column to a view and a materialized view.

Does Oracle allows the COMMENT ON syntax with views?

Answer:  Yes, Oracle treats table and view alike with the COMMENT ON clause, and you can add a comment to a materialized view with the COMMENT ON MATERIALIZED VIEW clause.  

--************************
-- Comment a table entry
--************************  

comment on table
    scott.emp
is
    'This is a comment on the employee table , , , ';  

--************************
-- Comment a view entry
--************************  

comment on table
    scott.empview
is
    'This is a comment on the employee view, a collection of tables , , , ';  

--************************
-- Comment a materialized view
--************************    

comment on materialized view
    scott.emp_mv
is
    'This is a comment on a materialized view, a pre-created collection of table rows , , , ';
