Re: Can't create simple MV with FAST refresh
Jesse,
don't have much experience with mv, but shouldn't "rowid" be included in
"select" list?

RE: Can't create simple MV with FAST refresh
OK, so the MetaLink article seems to be really incomplete, as I found this hidden in the docs: "The WHERE clause can contain only joins and they must be equi-joins (inner or outer) and all join predicates must be connected with ANDs. No selection predicates on individual tables are allowed." OK, so I can't have selection predicates with a FAST refresh -- at least in 8i. So Im not sure an MV is going to give me a significant advantage here over a trigger. I just dont like the impact of several insert/update triggers (or one big one) on our G/L.

RE: Can't create simple MV with FAST refresh
Thanks, but as I had mentioned, I've already tried that.
One part I didn't include is that the table does not have a primary key and
cannot be made to have one, so I'm using ROWID.

RE: Can't create simple MV with FAST refresh
Maybe the IN clause is throwing it?
Try it with -
where trans_type = 'A' or trans_type = 'B'
Just a WAG...

Hi all,
Using 8.1.7.4.0 on HP/UX with COMPATIBILE set to "8.1.7", I'm not able
to
create the following simple MV:
CREATE MATERIALIZED VIEW qt_gl_trans_ab_mv
TABLESPACE qt_mat_view
BUILD IMMEDIATE
USING INDEX TABLESPACE qt_mat_view PCTFREE 15 INITRANS 2
REFRESH FAST WITH ROWID
USING LOCAL ROLLBACK SEGMENT rbsbig
START WITH SYSDATE
NEXT (TRUNC(SYSDATE+1) + 4/24)
AS
select fiscal_year, fiscal_period, account_no,
trans_type, trans_amount
from my_general_ledge
where trans_type in ('A','B')
It errors with ORA-12015 "cannot create a fast refresh snapshot from a
complex query". According to MetaLink doc 179466.1, a complex query in
a MV
on 8.1.7 is one that has at least one of:
- a distinct or unique keyword
- an aggregate function (e.g. avg, count, max, min, sum, )
- a connect by clause
- a group by or order by clause
- a set operator (UNION, UNION ALL, INTERSECT and MINUS)
- joins other than those in a subquery
But my query has none of those? Thinking somethings hosed or I'm
completely
misunderstanding the "IN" operator of the WHERE clause, I tried "where
trans_type = 'A'", but with the same results.
Also, I've created the MV log for the fast refresh:
CREATE MATERIALIZED VIEW LOG ON my_general_ledger
WITH ROWID
I'm just testing out MVs here, but I'm missing something real simple
and/or
stupid here, but for the life of me I can't see what (even after a lunch
break).
Anyone?
