does the query needs a hint to access a materialized view?
Answer / gautam choudhury
It's important to note that init.ora parameters
query_rewrite_integrity and query_rewrite_enabled are
required to use materialized views and function-based
indexes. if these two parameters are declared then hint is
not required to access a materialized view.
QUERY_REWRITE_INTEGRITY =ENFORCED
QUERY_REWRITE_ENABLED = TRUE
There are three acceptable values for
query_rewrite_integrity:
enforced (default) - Presents materialized view with fresh
data
trusted - Assumes that the materialized view is current
stale_tolerated - Presents materialized view with both
stale and fresh data
