Oracle hint: MATERIALIZE
/*+ materialize */
is an undocumented
hint
.
The hint causes the result of a query in a
with
clause
to be stored in a
global temporary table
.
Thus, the hint is useful if this result is referred to multiple times in the query. Compare with
cache
and
inline
. Apparently, an inline view is materialized when it uses
rownum
.
