Specifies that materialized query table recommendations be generated for REFRESH DEFERRED tables. MQTs specified with REFRESH DEFERRED will not reflect changes to the underlying base tables unless a REFRESH TABLE statement is issued.
MQTs with REFRESH DEFERRED can improve the performance of dynamic SQLs only. After creating deferred MQTs, you must set the CURRENT REFRESH AGE special register to ANY.
