Oracle Materialized View在提交时不会快速刷新

Question

我可以使用REFRESH FAST ON COMMIT创建MVIEW。但是，当我插入或更新基础表（例如Capture_date列）时，视图不会刷新。它只能在我指定REFRESH FORCE ON COMMIT时刷新，但由于性能问题，我不想完全刷新。

CREATE MATERIALIZED VIEW LOG ON EXP_DC_HST 
WITH SEQUENCE, ROWID 
(ACTIVITY_DESCRIPTION, ACTIVITY_TYPE, CD1, CD2, CD3, CD4, Capture_date) 
INCLUDING NEW VALUES; 

CREATE MATERIALIZED VIEW EXP_DC_AMEND_MVIEW 
PARALLEL 
BUILD IMMEDIATE 
REFRESH FAST ON COMMIT AS 
select H.ACTIVITY_DESCRIPTION, H.ACTIVITY_TYPE, H.CD1, H.CD2, H.CD3, H.CD4, H.CD1|| H.CD2|| trim(H.CD3)||'-'||LPAD(H.CD4,2,0) as EXP_DC_NUMBER, 
max(H.Capture_date) as DC_STATUS_TIME 
from EXP_DC_HST H where H.ACTIVITY_TYPE = 'AMENDMENT' 
AND INSTR(H.ACTIVITY_DESCRIPTION, 'INFORMAL') = 0 
group by H.ACTIVITY_DESCRIPTION, H.ACTIVITY_TYPE, H.CD1, H.CD2, H.CD3, H.CD4;
