Materialized Views Not Used With UNION ALL In Query
Oct 13, 2010I am an Oracle newbie.
We have 2 fact tables and one lookup table in this structure:
FACTTABLE1 (C1_ID, C2, SALE)
FACTTABLE2 (C1_ID, C3, SALE)
LOOKUPTABLE (C1_ID, C1_NAME)
The DBAs have built 2 Materialized Views, which aggregates data in the fact tables at column C1 level
MAT_VIEW1 :SELECT C1_ID, SUM(SALE) SALES from FACTTABLE1 join LOOKUPTABLE on C1_ID
MAT_VIEW2: SELECT C1_ID, SUM(SALE) SALE from FACTTABLE2 join LOOKUPTABLE on C1_ID
We are using an old BI tool that can ONLY generate Inline Views in these formats.
CASE1:
select
INL_VIEW.C1_ID
,LOOKUPTABLE.C1_NAME
,sum(SALE) SALE
from
(select C1_ID, C2_ID, null C3_ID, SALE from FACTTABLE1)INL_VIEW
join LOOKUPTABLE
on INL_VIEW.C1_ID = LOOKUPTABLE.C1_ID
group by INL_VIEW.C1_ID, LOOKUPTABLE.C1_NAME
CASE2:
select
INL_VIEW.C1_ID
,LOOKUPTABLE.C1_NAME
,sum(SALE) SALE
from
(select C1_ID, null C2_ID, C3_ID, SALE from FACTTABLE2)INL_VIEW
join LOOKUPTABLE
on INL_VIEW.C1_ID = LOOKUPTABLE.C1_ID
group by INL_VIEW.C1_ID, LOOKUPTABLE.C1_NAME
CASE3:
select
INL_VIEW.C1_ID
,LOOKUPTABLE.C1_NAME
,sum(SALE) SALE
from
(
select C1_ID, C2_ID, null C3_ID, SALE from FACTTABLE1
union all
select C1_ID, C2_ID, null C3_ID, SALE from FACTTABLE2
)INL_VIEW
join LOOKUPTABLE
on INL_VIEW.C1_ID = LOOKUPTABLE.C1_ID
group by INL_VIEW.C1_ID, LOOKUPTABLE.C1_NAME
Oracle 11g rewrites Case 1 and Case 2 to use the correct materialized views. But for case 3, it goes to the base fact tables 1 and 2. Is there a way to make oracle use the MVs even if there is a UNION ALL in the inline view? There is a 1:M Foreign Key relationship between LOOKUPTABLE.C1_ID and the 2 fact tables.
Replication :: Sub-query In Materialized Views
Apr 1, 2009I have a view with complex query that have grouping and aggregations in sub-queries.
Now we would like to change it to a materialized view. However, materialized view does not support GROUP BY clause in sub-query. The solution is to create several view for the sub-queries and then create a materialized view based on it. It seems it can work, but I guest every time complete refresh is required.

PL/SQL :: Materialized View - Update Query Without Drop And Recreate
Aug 24, 2012i have a little doubt in Materialized view. i created a materialized view and log with the following query,
create table test_mv (a number ,b number )
alter table test_mv add constraint t_pk primary key ( a );
insert into test_mv values (1,2);
[Code]...
Now i want to update the query in the MV as 'Select a from test_mv' . for that i tried with
*'ALTER MATERIALIZED VIEW product_sales_mv AS SELECT a from test_mv;'*
But it throwing error,
Error starting at line 5 in command:
alter MATERIALIZED VIEW product_sales_mv AS SELECT b from test_mv
Error report:
SQL Error: ORA-00933: SQL command not properly ended +00933. 00000 - "SQL command not properly ended"+
*Cause:+

i guess i am doing wrong. i want to update it without drop and recreate

SQL & PL/SQL :: Create Materialized Views Depending On Sysdate With Enable Query Rewrite Option
Mar 28, 2011I want to create a materialized view for the last 10 days with the enable query rewrite option.
e.g. i want to create a view with the list of employees who joined the company in the last 10 days.
create materialized view M_Employee
refresh fast on commit
enable query rewrite as
select joining_date , name
from
employee
where joining_datde < TRUNC(sysdate) - 10
I seem to get the error SQL Error: ORA-30353: expression not supported for query rewrite
30353. 00000 - "expression not supported for query rewrite"
*Cause: The select clause referenced UID, USER, ROWNUM, SYSDATE.
This error is self explanatory , but is there any work around to have a query liek this to list the employees based on sysdate.
Refresh Materialized Views Based On Remote Views?
Aug 4, 2011I have a created a materialized view which is based on a view on remote database. Now how do I refresh the view.
Materialized view is created by
CREATE MATERIALIZED VIEW mv_employee_name
AS SELECT EMPLID, EMPL_NAME
FROM VEMPDATA@REMOTEDB
WHERE REGION = 'US';
I am wondering how the refersh happens or how do I specify the refresh clause.REFRESH FAST option is looking for VIEW LOG on the master table but in this case its a remote view, so I cannot create any object on remote db.
PL/SQL :: Get List Of Materialized Views / Views Using Column Of Table

View 3 Replies View RelatedConvert Some Existing Materialized Views (fast Refresh) To Partition Materialized Views
Jul 7, 2010I have to convert some existing materialized views (fast refresh) to partition materialized views.
Database version is oracle 10.1.0.4. I have decided to use on prebuilt table option to do the partitioning as it minimizes the time to transfer from the master site.
1) stop replication
1) create interim tables with similar structure as the materialized views
2) transfer all data from the materialized views to the interim tables
4) script out the materialized views structure and add in on prebuilt table option in the scripts
5) drop the materialized views
6) rename the interim tables with the same name as the materialized views
7) run the scripts to create the materialized views with on prebuilt table option
8) refresh the newly created materialized views -> it should take a short time since I am using on prebuilt table option
But I am facing one major issue. That is if I drop the materialized views, the materialized view logs of the master tables are purged. When the materialized views are refreshed fast, there are some data missing. the data that are purged out when the materialized view are dropped.
Do you happen to know other ways that existing materialized views can be converted to partitioned materialized views? Do you have any workaround to prevent the materialized view logs from being purged?

PL/SQL :: Single Sub Row Query Returns More Than 1 Row?
Apr 19, 2013I am trying to update values in a table from another table and getting the error: Single Sub Row Query Returns More Than 1 Row.
I want table B's PRV_NAME updated into table A's PRV_NAME where A.PRVID = B.PRVID where B.PRV_TYPE = M'
Both tables have all unique PRVID's, however, table B has PRVID's that have the same name. So table B data can look like this:
PRVID PRV_NAME
1234 PHOENIX MED
1235 SAC MED
1236 SAC MED
1237 OVERLAND
etc..
So, as you can see the PRVID's are unique, but not the PRV_NAME's. Is this the reason why I get this error?
I did not build the tables and have no control over what is put in them. If this is the reason for the error, is there any way to resolve this?
For reference, here is the query.
update msb_prv_source ps
set ps.prv_name =
(select prv00.prv00_prv_name
from prv00_prv prv00
join msb_prv_source ps
on prv00.prv00_prv_id = ps.prvid
where prv00.prv00_prv_type = 'M')
PL/SQL :: Select Top Row In Single Query?
Sep 19, 2013write a query to get the first row after order by clause using single query alone.Example:I can write following query to select first rowselect * from (selec * from t order by col1) where rownum = 1;But here I should not use inline view to get the result. Because my original requirement needs to use this query in select list and it needs to use a column (of a table from the FROM clause) in the where clause of inline query. Because there is restriction that we can not use the column (of a table from the FROM clause) more than one level of inline query.

SQL & PL/SQL :: Select Single Query And GroupBy Together?
Jul 8, 2011i have a problem in the following query. i need to fetch the rows such that i want to fetch all the records keeping "segment1" column as distinct and sum all of the corresponding "quantities" column.
select prha.segment1 --as requisition_no
,prha.creation_date
,sum(prla.quantity)
,prha.description
[code]...
i tried to use the partition technique. using partition solved the problem apperently. the sum function worked but redundancy in "segment1" column still persists. i used the sum function only to extract the distinct "segment1" column and summing its corresponding "quantity" column (only quantity column differs in the redundant rows...)
the second query was like:
SELECT prha.segment1,
prha.creation_date,
SUM(prla.quantity) OVER(PARTITION BY prha.segment1) AS qty,
prha.DESCRIPTION,

SQL & PL/SQL :: Single Quote(') In Query Not Working?
Jan 5, 2013I have table say Messages. In which there is a column msg_text varchar2(900).My requirement is to fetch the very last character of the msg_text for a single row identified by its msg_code(primary key).
The problem is, whenever msg_text contain second last character as single quote( ' ), it doesn't give me the last character i.e. after the single quote.For example if msg_text is "Congratulations, you opted for 'A'." and if its message_code is 10 then query
SQL> SELECT SUBSTR(msg_text,LENGTH(msg_text),LENGTH(msg_text)) AS LAST_CHAR
FROM messages
WHERE msg_code = 10;
returns nothing.
Whereas if msg_text is "Are you sure to continue?" and if its message_code is 20 then query
SQL> SELECT SUBSTR(msg_text,LENGTH(msg_text),LENGTH(msg_text)) AS LAST_CHAR
FROM messages
WHERE msg_code = 20;
returns character '?'.
