Iam trying to refresh the materialized view by using:
DBMS_MVIEW.REFRESH('v_materialized_foo_tbl')
But it's throwing invalid sql statement.
Then I have created a stored procedure like this:
CREATE OR REPLACE
PROCEDURE MAT_VIEW_FOO_TBL
IS
BEGIN
DBMS_MVIEW.REFRESH('v_materialized_foo_tbl')
END MAT_VIEW_FOO_TBL IS;
This procedure has been created successfully but when i am calling this procedure with
MAT_VIEW_FOO_TBL;
it's throwing an error again.
Kindly suggest a solution for this issue.
Thanks, Srinivas
To update the data in a materialized view, you can use the REFRESH MATERIALIZED VIEW statement at any time. When you use this statement, Amazon Redshift identifies changes that have taken place in the base table or tables, and then applies those changes to the materialized view.
So if you want to refresh mview daily, you need to keep it refresh on demand and set the next refresh time as sysdate + 1 . You can set any interval although. Once you do this the materialized view is created and a job is set in Oracle that will refresh mview every 24 hrs (sysdate + 1) .
Materialized views can be refreshed in two ways: fast or complete.
How do I force a refresh of a materialized view? Answer: Oracle provides the dbms_mview package to manually invoke either a fast refresh or a complete refresh, where F equals Fast Refresh and C equals Complete Refresh: execute dbms_mview.refresh('emp_dept_sum','f'); Get the Complete. Oracle SQL Tuning Information.
Run this script to refresh data in materialized view:
BEGIN DBMS_SNAPSHOT.REFRESH('Name here'); END;
try this:
DBMS_SNAPSHOT.REFRESH( 'v_materialized_foo_tbl','f');
first parameter is name of mat_view
and second defines type of refresh
. f denotes fast refresh.
but keep this thing in mind it will override any any other refresh timing options.
