Materialized View: New column in master table is not replicated
Date: Thu, 13 Nov 2008 18:49:06 +0100
I created this Materialized View to replicate a table to another database:
CREATE MATERIALIZED VIEW MyTblName TABLESPACE MyTblSpace REFRESH FAST AS
SELECT * FROM MyTblName_at_l_source;
Anything works fine!
Now I added a new column "Field4" to the master table in the source
I expected that the new column is replicated automatically because I used
"SELECT * FROM MyTblName_at_l_source"
But the new column is not replicated to the destination database. I think the reason is that Oracle (10g) ported the "SELECT * FROM MyTblName_at_l_source" to
SELECT "MyTblName"."Field1" "Field1","MyTblName"."Field2"
"Field2","MyTblName"."Field3" "Field3" FROM "MyTblName"@l_source "MyTblName"
First question: Is it possible to create a Materialized View that
replicates a master table with all columns - new columns too?
Second question: I searched for a command something like "ALTER MATERIALIZED
to tell oracle to replicate the new column too. But I did not found it. Do I simply have to create the Materialized View once more?
Thanks for your help!
I appreciate it!
I searched a lot of documentations/books but did not found an answer!
