如果主表已更改，则oracle物化视图删除数据

Question

首次撰写物化视图。我使用物化视图日志创建了如下所示的物化视图。

CREATE MATERIALIZED VIEW LOG ON table1 WITH SEQUENCE, ROWID, PRIMARY KEY INCLUDING NEW VALUES;

CREATE MATERIALIZED VIEW LOG ON table2  WITH SEQUENCE, ROWID, PRIMARY KEY INCLUDING NEW VALUES;


    create materialized view test_hosp_mv
         refresh fast on commit
       as
    select h.hid, h.hospital_name, h.rowid h_rowid, hho.rowid hho_rowid from table1 h, table2 hho
    where h.hid = hho.hid
    and h.status = 'Approved'
    and hho.flag = 'Y'
    order by hid desc

物化视图已成功创建并将所有记录插入到mv中。问题是当主表（table1）中的状态更改为未批准时，即。 h.status ='未批准'，数据将从物化视图中删除。抱歉无能为力，但我可以停止从物化视图中删除数据吗？
