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

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

Have you tried to create a table with the correct structure and then by creating the view materialized, based on the predefined table as described here...

I don't want to refresh the mview when validation is performed on the base table.
And I don't want to change the base table by adding a primary key.

is it possible to create the mview journal using the unique index? or another solution?
Please help
Thanks in advance

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:

-----

This same script running in SQLDeveloper gives the same error in line 17, which is the FROM clause. BUT I can run the select by itself and returns the expected result. If the table exists in the correct storage space.

I must be missing something big...

Thanks in advance.

Joan

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
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!

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

Hi 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}

Create a view-only PDF

I need to create a view-only PDFs that cannot be printed, copied, transmitted or recorded electronically. I see the security settings for printing, but I'm still able to record and transmit the record. Is there a way to do this? I have Acrobat 7.0 Standard. Thank you.

You can do everything with security Acrobat except the file forward. Registration may be restricted, but is only the changes. When a PDF file is downloaded to see, it's a machine (usually in the TEMP folder). If you want to restrict the use, you are talking about an expensive solution with DRM LiveCycle process. Acrobat itself cannot restrict the availability of the PDF file. If this is of concern, then you can trust the user, not forward it or use DRM.

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:

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,

LEFT OUTER JOIN BROKER brk ON brk.brkno = c.brkno
LEFT OUTER JOIN CORPORAT r

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

but I get an error message:
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.
Specify

FROM indiv i,indivcoding c, broker brk, corporat r
WHERE brk.brkno(+) = c.brkno
AND c.ncmpcode(+) = r.cmpcode

FROM indiv i,indivcoding c, broker brk, corporat r
WHERE c.brkno = brk.brkno(+)
AND r.ncmpcode = c.cmpcode(+)

(I find it more readable).

change the source tables in the materialized view

If I change the name of the source table in a materialized view, I have to delete and recreate the MV? For example, My MV uses a table from a DBlink. Instead I want to physically copy the table in the schema, and then create the MV using the local table, then change MV to use the remote table and I expect to start refreshing the MV for incremental data. Can I do it?

No, you can't. Oracle has no way of knowing that the modified table (name) is identical to the original table.

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.

performance of the queries on the main tables of the materialized view vs
Hello

I'm afraid of strange behavior in db, on my paintings of master UDBMOVEMENT_ORIG (26mil.rows) and UDBIDENTDATA_ORIG (18mil.rows) is created the materialized view TMP_MS_UDB_MV (UDBMOVEMENT stands for this object) that meets certain default conditions and the join on these paintings of master condition. MV got on the lines of 12milions. I created MV for poll not so huge objects, MV got 3GB, paintings of master toghether 12 GB. But I don't understand that physical reads and becomes compatible is less on MV that on the main tables, the final execution time is shorter on the master tables. See my journal below.

Why?

What you base that statement on?

I do not see any table full scan in terms of the second query. All I see is

Generate the ddl to create materialized view log...

Hi gurus...

Oracle db: 11g

I am trying to generate / excerpt from script MVIEW Logs from prod to be applied on the test.
I tried
< code >
DBMS_METADATA. GET_DDL (decode(object_type,'materialized_view_log'), object_name, owner)
from dba_objects
where owner = < ABC >;
< code >

above fails, any ideas?

Thank you

Please try to use the tags in code, but you need to add.

 on the line before and the line after your code instead of what you are using.

The object type names are case-sensitive so you need to use

DBMS_METADATA. GET_DDL ('MATERIALIZED_VIEW_LOG', object_name, owner)

Why are you using DECODE?

Create table works, create materialized view only - long column names?
