SELECT CAPABILITY_NAME, POSSIBLE, MSGTXT 
FROM MV_CAPABILITIES_TABLE
WHERE CAPABILITY_NAME LIKE 'REFRESH%';

CAPABILITY_NAME P
------------------------------ -
MSGTXT
--------------------------------------------------------------------------------
REFRESH_COMPLETE Y

REFRESH_FAST N

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

CAPABILITY_NAME P
------------------------------ -
MSGTXT
--------------------------------------------------------------------------------
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

发现是因为没有包括各个表的rowid

于是改为:

CREATE MATERIALIZED VIEW mv_vcard_last_hlrlist refresh fast as
select hlrlist.rowid arowid,last.rowid browid,vcard.rowid crowid, vcard.username,
vcard.nick_name,vcard.pcode,hlrlist.region,
vcard.birth_year, vcard.icon, vcard.descr, last.state,
vcard.HLR_CITY, vcard.BIRTH_MONTH, vcard.BIRTH_DAY
from hlrlist ,last ,vcard 
where vcard.username = last.username and vcard.hlr_city = hlrlist.hlr_id and last.state='Online' ;
