get the comment of the materialized view

Question

good evening,

which is the table or the select I need to get the comment of a materialized view

the comment adds it like this:

comment on MATERIALIZED VIEW TEST33 is 'hello';

try with:

SELECT t.table_name, t.comments FROM USER_TAB_COMMENTS t WHERE TABLE_NAME = 'TEST33';


SELECT * FROM USER_MVIEWS

I cannot locate the table where this information is stored.

I will appreciate your help.

Thanks a lot.

To get Comments on Materialized view:USER_MVIEW_COMMENTS, for comments on columns in MV: USER_COL_COMMENTS

--Comments on Materialized view
SQL>SELECT * FROM user_mview_comments
WHERE mview_name='CAL_MONTH_SALES_MV'

MVIEW_NAME           COMMENTS
-------------------- --------------------
CAL_MONTH_SALES_MV   Monthly total sales




--comments on columns in MV
  SQL>SELECT * FROM user_col_comments
  WHERE table_name='CAL_MONTH_SALES_MV'

TABLE_NAME           COLUMN_NAME          COMMENTS             ORIGIN_CON_ID
-------------------- -------------------- -------------------- -------------
CAL_MONTH_SALES_MV   CALENDAR_MONTH_DESC  Monthly Calender                 3
CAL_MONTH_SALES_MV   DOLLARS              Monthly Total                    3
