Hey all.

When you do a complete refresh of a materialized view, does it do a truncate prior and then populate it, in effect removing the table for as long as its rebuilding it?

in 9i mechanism is truncate/insert /*+ append */
in 10g default is delete/conventional insert, although one can switch back to 9i mechanism using atomic_refresh = false in dbms_mview.refresh proc.
