Guys,

Please help me with ...

I need to create a Materialized View, which should refresh every Tuesday and Friday at 5am.

CREATE MATERIALIZED VIEW DUAL_MV
TABLESPACE USERS_SMALL
REFRESH NEXT NEXT_DAY(TRUNC(SYSDATE), 'TUESDAY') + 05/24
AS SELECT * FROM DUAL;

I can do it for single day like above, but how to refresh on multiple days, using create materialized view syntax ........

You can use a CASE expression, if current is TUESDAY then use SYSDATE+1+5/24 otherwise use your current expression (CASE WHEN ELSE).
