Can't create the mview with refresh on each commit

Question

I have these underlying tables:
SQL> desc ta_footn_typ
Namn Null? Typ
FOOTN_TYP_ID NOT NULL VARCHAR2(2)
APPL_COD CHAR(1)
NATIONAL_DATA NUMBER(1)
(FOOTN_TYP_ID is a PK)
SQL> desc TA_S_DESC_FOOTN_TYP
Namn Null? Typ
FOOTN_TYP_ID NOT NULL VARCHAR2(2)
LANG_COD NOT NULL CHAR(2)
FOOTN_TYP_DESCR VARCHAR2(100)
(FOOTN_TYP_ID and LANG_COD is a composite PK)
from these two tables I would like to build a mateerialized view with refresh
on commit with the following select-statement:
select type.*, eng.FOOTN_TYP_DESCR as FOOTN_TYP_DESCR_ENG, nat.FOOTN_TYP_DESCR
as FOOTN_TYP_DESCR_NAT from TA_FOOTN_TYP type
left join TA_S_DESC_FOOTN_TYP eng on eng.FOOTN_TYP_ID = type.FOOTN_TYP_ID and
eng.LANG_COD='EN'
left join TA_S_DESC_FOOTN_TYP nat on nat.FOOTN_TYP_ID = type.FOOTN_TYP_ID and
nat.LANG_COD='EE'
I can create the mview with the options:
on demand, automatically on, never
but that is not interesting for me,
I need refresh on commit on the underlying
tables.
So I tried -->
CREATE MATERIALIZED VIEW "EMTS_NF"."MY_MVIEW"
TABLESPACE "EMTS_EMTS_NF"
BUILD IMMEDIATE
USING INDEX
TABLESPACE "EMTS_EMTS_NF"
REFRESH FORCE
ON COMMIT
AS
select type.*, eng.FOOTN_TYP_DESCR as FOOTN_TYP_DESCR_ENG, nat.FOOTN_TYP_DESCR
as FOOTN_TYP_DESCR_NAT from TA_FOOTN_TYP type
left join TA_S_DESC_FOOTN_TYP eng on eng.FOOTN_TYP_ID = type.FOOTN_TYP_ID and
eng.LANG_COD='EN'
left join TA_S_DESC_FOOTN_TYP nat on nat.FOOTN_TYP_ID = type.FOOTN_TYP_ID and
nat.LANG_COD='EE';
But it gives mee ORA-12054,
any advices???

Answer 1

Try it with REFRESH FAST instead of REFRESH FORCE.
