Modify Snapshot without drop RH Linux 9.2.0.5 I need to alter my base table (add columns) and thus also the remote db MView referring to it. I don't mind doing some RTFM and I have been on Metalink this morning without much luck.
I just tried this on Oracle 10.2.0.2 on Linux: Create table Create MV log on table Create Mv on source table ( all in same account on one database) Add column to source table Add same column to MV table unregister and register snapshot with a new query via dbms_mview.register A complete refresh still works for the original columns, but does not update the new column. Adding the query via dbms_mview did not have any effect on sys.snap$.query_txt (as seen in dba_snapshots) Updating sys.snap$ directly with a new query did not fix it either. However, monkeying with snap$ did break the DD, as the following error will show: 11:48:49 SQL> / alter materialized view mv_target compile * ERROR at line 1: ORA-12003: materialized view "MV_TARGET" does not exist Oops. I guess that is why we don't modify the Data Dictionary. :) There's probably other ways to go about this, but this is the only one I tried. -- Jared Still Certifiable Oracle DBA and Part Time Perl Evangelist
