How to refresh materialized view in oracle

Question

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

Answer 1

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.

Answer 2

Try using the below syntax:

Common Syntax:

begin
dbms_mview.refresh('mview_name');
end;

Example:

begin
dbms_mview.refresh('inv_trans');
end;

Hope the above helps.

Run this script to refresh data in materialized view:

BEGIN
DBMS_SNAPSHOT.REFRESH('Name here');
END;
