REFRESH_COMPLETE Y

REFRESH_FAST N

REFRESH_FAST_AFTER_INSERT N

the SELECT list does not have the rowids of all the detail tables

REFRESH_FAST_AFTER_ONETAB_DML N

see the reason why REFRESH_FAST_AFTER_INSERT is disabled

REFRESH_FAST_AFTER_ANY_DML N

see the reason why REFRESH_FAST_AFTER_ONETAB_DML is disabled

REFRESH_FAST_PCT N

PCT is not possible on any of the detail tables in the materialized view

發現是因為沒有包括各個表的rowid

于是改為:

CREATE MATERIALIZED VIEW mv_vcard_last_hlrlist refresh fast as

select hlrlist.rowid arowid,last.rowid browid,vcard.rowid crowid, vcard.username,

where vcard.username = last.username and vcard.hlr_city = hlrlist.hlr_id and last.state='Online' ;
