Creating Materialized View On Remote Simple View
Dec 11, 2012I'm trying to create a Materialized View on a remote database from a simple view. The reason is, the data owners don't want to grant explicit tables privileges to external subscribers.
A new schema is created to publish data in the form of a view. I've created mlogs on the master tables, and granted them to the subscriber, but it's still complaining about a missing primary key on the view. A primary key does exist in the master table.
Is there another work around for this situation without having to work inside the data sources' environment?
Creating List Of Items And Using Foreign Keys As Primary
May 19, 2007How can I create a list of items in a field, for instance lets say I have a table called car and one of the sub categories is parts. How can I make it so that parts can be any number of pre-defined entities? Or even table, for instance if I make a table called parts how can I use that in the car table in place of parts?
My second question is about using foreign keys as primary keys. If I am writing an email sql DB and I decided to use the members usrname as the primary key in the member table but then made another table that lists all the emails and decided to make the foreign key member username the primary key there.
Is that safe to do or should i create a sequence in which to identify a primary key for the email list table? Also what if I extend member to several other tables and use it as a primary key there too, seems like a kind of dangerous way to do things...
SQL & PL/SQL :: Foreign Key View In Oracle
Sep 6, 2011Is there any view in oracle which gives the foreign key mapping.
E.g.
Table DEPT has DEPTNO as PK.
Table Emp has DEPTNO as FK to DEPT.DEPTNO.
I can get the information for DEPT table from R_CONSTRAINT_NAME column of all_constraints table.My requirement is to get the the which column of Emp table refers to DEPT.DEPTNO column .
SQL & PL/SQL :: Primary Key On A View
Dec 20, 2011While making a view.
1. Is it advisable to have primary key in a view.
2. Why can't we have a primary key in a view, what are its advantages. I mean one cannot search a view by index.
3. Is it because of hibernate, but again i have used distinct keyword in a view declaration which means i cannot insert via view.
Here is my code for view to make a primary key in a view.
CREATE OR REPLACE FORCE VIEW VU_NAME
PRIMARY_KEY, NAME_ID, ADDRESS_ID
)
[Code]....
alter view VU_NAME add constraint vemp_pk primary key (PRIMARY_KEY) disable
SQL & PL/SQL :: Primary And Foreign Key On Same Column And Foreign Key Index
Aug 25, 2010Create table Car
(Car_cd VARCHAR2(5),
Car_Desc VARCHAR2(50)
);
alter table Car
add constraint Car_PK primary key (Car_CD);
INSERT INTO Car (Car_Cd, Car_Desc) VALUES ('CORLA','COROLLA');
Commit;
[code]....
The requirement necessitates a new table to map car to manufacturer. This mapping table may later be expanded to contain other attributes Engine, MPG, etc to hold details specific to a car.But this is in future.
Create Table Car_Mapping_Details
(Car_Cd VARCHAR2(5),
Manufacturer_Cd VARCHAR2(5));
--Primary Key Constraint
ALTER TABLE Car_Mapping_Details
ADD CONSTRAINT Car_Mapping_Details_pk PRIMARY KEY (Car_Cd );
--Not able to create this as Car_cd is already a PK in this table and therefore has Unique Index
ALTER TABLE Car_Mapping_Details ADD CONSTRAINT Car_Mapping_Details_fk1
FOREIGN KEY (Car_Cd)REFERENCES Car (Car_Cd);
[code]....
But in this case the Car_Mapping_Details.Car_cd is itself is a primary key and therefore has Unique index.Although I was able to create foreign key constraint on Car_mapping_details.car_cd column (which is also Primary Key), I was not able to create Foreign Key Index on this column. It gives me Quote:ORA-01408: such column list already indexed.In other words, not creating foreign index for foreign key column lead to table-level lock? Or will the Unique Index in that primary key column be sufficient to avoid table-level lock?

View 10 Replies View RelatedCan Materialized View Primary Key Be Moved To Different Tablespace
Aug 29, 2012I created a materialized view with REFRESH FAST WITH PRIMARY KEY, which I assume generated its own PK for the materialized view (well, something certainly did, and it wasn't me); however, I did not include USING INDEX TABLESPACE <tablespace>, so the PK was generated in the same tablespace as the materialized view itself. The "problem" is, this particular database has a separate tablespace into which all of the indexes are supposed to go.
Is there any way, short of dropping and recreating the materialized view (which took 24 hours in the first place), to move the system-generated PK to a different tablespace?
For that matter, is there a reason why I wouldn't want to do this?
Creating Materialized View Log
Feb 7, 2013There are 2 databases, database A and database B. Database A is Oracle 11.2.0.2 which runs on linux and Database B is Oracle 11.2.0.2 which runs on windows xp machine. In database A, there are 100's of tables which are being updated every 10 minutes or 15 minutes. For reporting purpose, the developer wants to run report for the tables. But since database A is being updated every now and then, generating reports takes almost 15 to 20 minutes. So the reports can be generated in Database B. Once in a day the database B should have the updated data from database A so that the reports can be generated in database B with less time. What could be the best solution for the database B to have the updated data on daily basis from database A in oracle?

Error In Creating Materialized View With DB Link?
Aug 7, 2013we have the following requirement for creating materialized view.
In database "DB1", a table "abc" is there in "user1" schema.
In database "DB2", in "user2", we are accessing the "abc" through DB link "DBL1" to DB1:
select * from user1.abc@DBL1;
we have created a public synonym for "user1.abc@DBL1" as "sabc".
In database "DB3", we need to create the materialized view to access "abc" in DB1 through DB2. we are not allowed to access "DB1" directly from "DB3". so we create a db link as "DBL2" in "DB3" to "DB2".
when i try to create a materialized view as below:
create materialized view abc_mv
as
select * from sabc@DBL2;
But got the error as "synonym translation invalid". When i access the SQL statement separately as below
select * from sabc@DBL2, its working but in Materialized view, it shown that error. Even i tried with schema name as well like "user2.sabc@DBL2" , but that also thrown same error.
Is there any option available for this type of creating materialized view?

Error In Creating Update Table Materialized View
Aug 28, 2013we are trying to create a materialized view (MV) which would access the remote database through db link. Now we need to do update on the local MV so that it should be reflected on the master table.
There is no primary key on this table and we are using "complete refresh" option. since we dont have control over remote database, we are not allowed to create MV log over there.
in this scenario, if i try to create updatetable MV with complete refresh, we are getting below error:

how to create such MV on this scenario?
our environment is:
