FAST_REFRESHABLE
VARCHAR2(18)
Indicates whether the materialized view is eligible for incremental (fast) refresh. Oracle calculates this value statically, based on the materialized view definition query:
NO - Materialized view is not fast refreshable, and hence is complex
DIRLOAD - Fast refresh is supported only for direct loads
DML - Fast refresh is supported only for DML operations
DIRLOAD_DML - Fast refresh is supported for both direct loads and DML operations
DIRLOAD_LIMITEDDML - Fast refresh is supported for direct loads and a subset of DML operations |
