I have a very simple Materialized view when I try to compile it I got this error: ORA-12013: updatable materialized views must be simple enough to do fast refresh So what kind of parameter do I have to set for auto updating MView, I want as soon as one of the tables involved in MVIEW is updated the MVIEW is update too.
