Question

Query regarding refreshing of materialized view:

Asked by: hema77

I have created a materialized view on a single table containing 'sum' function. I need to do 'fast' refresh of the materialized view. This I am doing using manual refresh i.e. using dbms_mview.refresh command. But it is not actually refreshing the materialized view. This command shows the insertion/updation/deletion in the log created on the table. Please help in this regards.

I think you hit the following bug:

BUG 814851
 Description: If a materialized view is created with an aggregate as a column,
 such as sum(b), then a failure can occur during refresh with
 DBMS_MVIEW.REFRESH_DEPENDENT() if the column is not aliased.
 
 Workaround: Provide an alias for such columns.  
example:
create materialized view PURCHASETOTAL
......
select id, sum(itemcost) SUMCOST
from purchases.......

  I had the same problem -- this seems to have fixed it...

hope this solves it for you...
