Cannot create Materialized View using the PL/SQL procedure
Hello
I have a question related to the creation of materialized view.
I have a stored procedure that creates the materialized view. When you try to perform this procedure, I get not enough privileges error: ORA-01031.
When I run the content of this procedure as a PL/SQL block anonymous their materialized view is created without any complications.
Can you please advice me on this subject?
It is even possible to create a materialized view in the stored procedure as I found no info on this subject.
Thank you
PetrHi chudapet,
Whenever you make in procedure, you must have direct subsidies and not through a role.
Most likely the grant to create a materialized view is available via a role to your username.
Assign a direct grant to the user:grant create materialized view to scott; {code}

is missing a closing parenthesis in create materialized view statement
Hi, I am using oracle 10g R2 and try to create a view of materalized with the following statement:
but I get an error message:CREATE MATERIALIZED VIEW MVT_DEC_TAB USING INDEX REFRESH FAST ON COMMIT AS select i.rowid as ind_rowid,c.rowid as indc_rowid,r.rowid as r_rowid,b.rowid as b_rowid,brk.rowid as brk_rowid, i.name,i.sname,i.address,i.tel,i.fax,i.email, DECODE(c.BRKNO,null,0,1) AS DEC_BRK, TO_TIMESTAMP(NVL(VEKDOV,'2001/01/01')||' 12:00:00','YYYY/MM/DD HH:MI:SS'), DECODE(c.brkno,null,DECODE(c.ncmpcode,null,c.vekdov,b.bcarddov),brk.validitydov) from indiv i,indivcoding c LEFT OUTER JOIN BROKER brk ON brk.brkno = c.brkno LEFT OUTER JOIN CORPORAT r ON c.ncmpcode=r.cmpcode INNER JOIN BCARD b ON b.bcardno=r.bcardno where c.typeact=2 and c.natcode=i.natcode and c.brkno is not null or c.ncmpcode is not null or c.nnatcode is not null
where c.typeact = 2
ERROR on line 11:
ORA-00907: lack of right parenthesis
which makes no sense because if I run the sql code of the materialized view, it runs normally.
I need to know what the causing this can someone help?Do not use the "LEFT OUTER JOIN" ANSI syntax in your CREATE MATERIALIZED VIEW definition.
SpecifyFROM indiv i,indivcoding c, broker brk, corporat r WHERE brk.brkno(+) = c.brkno AND c.ncmpcode(+) = r.cmpcode
OR
FROM indiv i,indivcoding c, broker brk, corporat r WHERE c.brkno = brk.brkno(+) AND r.ncmpcode = c.cmpcode(+)
(I find it more readable).

Create Materialized view and Materialized view log.
I wanted to create a materialized view with option "REFRESH QUICKLY YOU COMMIT".
(1) table 1 - it is partitioned range + list - added primary key
(2) View1 - having primary keys on the base table of view
Steps to follow:
(1) create the materialized on Table1; view journal -primary key by default
(2) create the materialized on view1 view log. -It gives below error.
ORA-00942: table or view does not exist
I wanted to create Materialized view as below
create a materialized view
Quickly REFRESH ON validation
as
Select...
........
... from table1
where c1 (select c1 from View1 which...);
Question:
(1) because I am getting above error when creating journal of MV on the view. Can one create log view MV or we create a MV newspaper on the base table of view?
(2) to create the MV with "REFRESH QUICKLY YOU COMMIT' option, we need to have the primary key on the main tables?
Pointers on this will be really useful.
Thank you
Prasad
"When a materialized view is maintained by the
ON
COMMIT
method, the time required to perform the validation can be slightly longer than usual." This is because the refresh operation is performed as part of the validation process. This is why this method may not be suitable if many users at the same time change the tables on which is based the materialized view. »See: basis of materialized views (refreshment options) for all the other options and how they work.

'Invalid metadata objects' when creating materialized views
Hi experts,
I ran into some trouble. I had an analytic workspace that has grown too quickly (see 11.2.0.2 size AW grows regularly with each generation of cube so I deleted and created a new.)
He seemed to do very well with the tip David Greenfield, gave us in the mentioned forum post, but when I try to activate materialized views (that I had activated in the previous workspace) I am gettig the following error:
-----

P.S.: In the above code I use 'SPACE' to replace the real name from username and a tablespace (which is the same) for reasons of confidentiality.When you run the select statement, you connect to the same user you are trying to activate the VM?
You can create a standard (No cube) MV with the same select statement? (Connected to the same user that you used in AWM).

Create Materialized View ORA-01723: columns of length zero are not allowed
I am trying to create a materialized view that derives from a column of a function and I get: ORA-01723: columns null are not allowed.
I use 10 gr 2 with the following definition (simple version):
CREATE MATERIALIZED VIEW ACES
SELECT
function_name (column_name) alias_de_colonne
FROM table_name;
I even tried to cast it as below:
CREATE MATERIALIZED VIEW ACES
SELECT
Cast (function_name (column_name) AS VARCHAR2 (200)) alias_de_colonne
FROM table_name;
My function has an exception to return a value, even if no value are.
I looked everywhere for the solution. Someone at - there a way around this problem? I really need my function to calculate the column because it has business rules that I can't join in my definition of the materialized view. My only hope around this is to insert values into a table and then create a materialized table view, I don't want to do that if someone has a solution around this.
Any help would be greatly appreciated.
Thank you

Hello
I found that when oracle executes the create materialized view statement it must be longer than the duration of execution of the actual query.
I do an IMMEDIATE CONSTRUCTION.
Is there a reason for this?
For example. the query in the create statement took 25 minutes and did not create the MV for 2 hours.
The following query, which took 10 seconds was not created during more than 11 minutes and is still ongoing.
So I want to know what the reason is behind this? pls share if you know... Thank you.
PS:
I have advice in the select query. Oracle uses it advice during the creation of MV too or is this the reason why it's taking the time to build the MV?
any suggestion is appreciated. thnks!

Create table works, create materialized view only - long column names?
Hello.
I have no probs creating a table as well: -.
CREATE TABLE blah
(
DEVICE_ID
)
in select
"Device_ID" AS DEVICE_ID
"of"sum" Device"@ed_link_3
where "Device_ID" < 5;
But when I try to create a materialized view:
Blah1 CREATE MATERIALIZED VIEW
(
DEVICE_ID
)
< various materialized view parms >
in select
"Device_ID" AS DEVICE_ID
"of"sum" Device"@ed_link_3
where "Device_ID" < 5;
It fails with errors: -.
ORA-04052: error occurred when searching to the top of the remote object Aggregate.Device@ED_LINK_3
ORA-01948: length of the name of the identifier (31) exceeds maximum (30)
Is there a way to get around this?
Is the problem with the columns of the remote table of device, which I do NOT need to import to have column names that are longer than 30 characters?
For now, I want only the Device_ID column which is a simple 9 characters long.
Oh, and the remote database is MySQL.
I'm uncomfortable with the < parms of materialized view > as they work fine when I choose a different remote table with only short column names.
Thank you.To my knowledge, you have the option
(a) create view (with shortened column names or only with desired columns if they are already less than 30 char limit) side of mysql
(b) use dbms_passthrough to force the analysis to be done on mysql (as in the example provided by SY here use dbms_passthrough to create a view )
However, I prefer to stick to one), because with dbms_passtrhough, you retrieve row by row.Best regards

I learned and referred website as much as we can not able to create a trigger in MView (sorry we create trigger but none use of creation because in view no insert and update happened). So I drop completely the materialized view concepts and relaxation.

This discussion will be useful for any future reference.

[8i] need help on query with a subquery/inline using UNION ALL view
OK, first of all let's start with some background info:
(1) I work in 8i
(2) some samples for my problem (please excuse the additional columns of data not used to this problem; I already had the sample laying around tables):
So, my first question was that I needed to find in the table RQMT who corresponded with everything on my VBOM have vbom.part_nbr table ' SAMPLE-1'. '. (Please note, in reality the VBOM table has thousands of rows of data, rather than just the 1 I have planned, some of them sharing the same vbom.part_nbr, others not). In addition to finding all RQMT data corresponding to the vbom.comp_part_nbr to vbom.part_nbr (where vbom.comp_part_nbr = rqmt.comp_part_nbr), I also need to find RQMT data for vbom.part_nbr itself (then, records where vbom.part_nbr = rqmt.comp_part_nbr).CREATE TABLE vbom ( part_nbr char(25) , bom_doc_nbr char(25) , bill_level number , comp_part_nbr char(25) , qty_per number ); --technically has primary and foreign keys, but whatever... --part_nbr is your top level (0) parent --comp_part_nbr is the specific child --bom_doc_nbr is the parent of the child (comp_part_nbr) and may be either part_nbr or a child of part_nbr that is also a parent INSERT INTO vbom VALUES ('SAMPLE-1','SAMPLE-1', 1,'SAMPLE-2',1); CREATE TABLE rqmt ( comp_part_nbr char(25) , prnt_part_nbr char(25) , ord_nbr char(10) , sub_ord_nbr char(3) , qty_reqd number , qty_issued number , date_reqd date , rqmt_stat char(2) , rqmt_type char(2) ); INSERT INTO rqmt VALUES ('SAMPLE-1','','S0000TEST1',001,30,0,TO_DATE('06/01/2010','mm/dd/yyyy'),'AL','ID'); INSERT INTO rqmt VALUES ('SAMPLE-2','SAMPLE-1','0000054963',001,15,10,TO_DATE('04/01/2010','mm/dd/yyyy'),'CL','DD'); INSERT INTO rqmt VALUES ('SAMPLE-2','SAMPLE-1','0000032562',001,5,5,TO_DATE('04/15/2010','mm/dd/yyyy'),'IS','DD'); INSERT INTO rqmt VALUES ('SAMPLE-2','SAMPLE-1','0000022341',001,5,4,TO_DATE('04/20/2010','mm/dd/yyyy'),'SH','DD'); INSERT INTO rqmt VALUES ('SAMPLE-2','SAMPLE-1','0000043469',001,10,0,TO_DATE('04/30/2010','mm/dd/yyyy'),'AL','DD'); INSERT INTO rqmt VALUES ('SAMPLE-2','SAMPLE-1','0000071235',001,10,0,TO_DATE('05/01/2010','mm/dd/yyyy'),'OP','DD'); INSERT INTO rqmt VALUES ('SAMPLE-2','SAMPLE-1','0000061224',001,5,0,TO_DATE('05/15/2010','mm/dd/yyyy'),'FP','DD'); INSERT INTO rqmt VALUES ('SAMPLE-2','SAMPLE-1','0000033294',001,5,0,TO_DATE('05/25/2010','mm/dd/yyyy'),'PL','DD');
To resolve this problem, I started with the following query:
It allows me to add a line to the top of the page parent (vbom.part_nbr), which does not exist in vbom.SELECT v.bill_level AS bill_lvl , v.comp_part_nbr AS component , v.bom_doc_nbr AS parent FROM VBOM v WHERE v.part_nbr ='SAMPLE-1' UNION ALL SELECT 0 AS bill_lvl , 'SAMPLE-1' AS component , NULL AS parent FROM DUAL
My first question is, is UNION ALL of the best way to do it, or could I do a kind of instruction based on the line number box (or something) that would be better? (in this application, or in the final query)
Then, I used the above query as a point of view online:
The problem here is that I have the same results (7 files) with the above query as I do with:SELECT a.bill_lvl , a.component , a.parent , r.ord_nbr , r.sub_ord_nbr , r.qty_reqd FROM ( SELECT v.bill_level AS bill_lvl , v.comp_part_nbr AS component , v.bom_doc_nbr AS parent FROM VBOM v WHERE v.part_nbr ='SAMPLE-1' UNION ALL SELECT 0 AS bill_lvl , 'SAMPLE-1' AS component , NULL AS parent FROM DUAL ) a , RQMT r WHERE a.component = r.comp_part_nbr
.. .it does not include RQMT recording for rqmt.comp_part_nbr = "SAMPLE-1'.SELECT v.bill_level , v.comp_part_nbr , v.bom_doc_nbr , r.ord_nbr , r.sub_ord_nbr , r.qty_reqd FROM VBOM v , RQMT r WHERE v.comp_part_nbr = r.comp_part_nbr AND v.part_nbr = 'SAMPLE-1'
To understand what was going on, I ran:
.. .and I get exactly this that I wait, 1 card for the SAMPLE-2 component and 1 plug for SAMPLE-1 (i.e. the recording I generated with the UNION ALL).SELECT a.bill_lvl , a.component , a.parent FROM ( SELECT v.bill_level AS bill_lvl , v.comp_part_nbr AS component , v.bom_doc_nbr AS parent FROM VBOM v WHERE v.part_nbr ='SAMPLE-1' UNION ALL SELECT 0 AS bill_lvl , 'SAMPLE-1' AS component , NULL AS parent FROM DUAL ) a
Then I ran:
.. .and I get all 8 records, whose SAMPLE-1.SELECT r.comp_part_nbr , r.ord_nbr , r.sub_ord_nbr , r.qty_reqd FROM RQMT r WHERE r.comp_part_nbr like 'SAMPLE-%'
So, it seems that the problem occurred when I join my opinion RQMT one online, although both separately seem to work very well.
A point to note: all parts of parent and child may not be appointed in the same way as in my example. SAMPLE-1 could have children of the SAMPLE-2, abc123, 20735, for example.
Any help on this would be appreciated, thanks!Hello
Concerns of problem by comparing 8 literal characters ' SAMPLE-1' for the 25-character CHAR column that contains "SAMPLE 1".»
17 spaces including the literal or use LPAD or CAST to 25 characters.
For example:SELECT a.bill_lvl , a.component , a.parent , r.ord_nbr , r.sub_ord_nbr , r.qty_reqd FROM ( SELECT v.bill_level AS bill_lvl , v.comp_part_nbr AS component , v.bom_doc_nbr AS parent FROM VBOM v WHERE v.part_nbr ='SAMPLE-1' UNION ALL SELECT 0 AS bill_lvl , CAST ('SAMPLE-1' AS CHAR (25)) -- CAST added here AS component , NULL AS parent FROM DUAL ) a , RQMT r WHERE a.component = r.comp_part_nbr ;
Is there a reason why you use CHAR instead of VARCHAR2? (One reason other than "I can't change it now.", otherwise said.)
