Can I actually insert data from a view? My understanding is no data actually exists in a view. This has created a cavernous feeling of inadequacy.

My local currency is INR, I need to write a query to convert the foreign currency to loacl currency INR.In my case i need to write aSQL for a view.It should not implement through PL/SQL
I have a table as shown below,
SQL> select * from Main_Table;
AA
--------------------
SUB1
SUB2
Here the SUB1 and SUB2 are "tables" and are similar in their structure. The "Main_Table" will be update dynamically and the no of rows in this table will vary.
Now my question , i need to create a view which will have all the rows from these tables ,in the current case it is something like
create or replace view sample
as
select * from SUB1 union all
select * from SUB2
How can this be achived. I tried as shown below:
spool file_to_exe.sql
select 'select * from ' || AA ||' union all ' from Main_table;
spool off
i will end up in a union all "extra" , if i do like this.
how can achieve this ?..

Create materialized view city-A_db_MV

select * from cityA.Tablea@city-Adb
When i select from city-A_db_MV, it showed the complete table-A of city-A database.
Now if we make any changes to City-A table at the Master site, will it be propagated automatically to the MV site.
I guess we need to create jobs to push / or refresh fast .. isnt it. But exactly how to do it is a question.
Secondly if we make a replication group at Master site at city-A db, how do we refresh that Group and how to monitor whether it is refreshing on time or not? do we need to see the jobs every now and then.
but still a lot of questions unanswered, even though i had read the documents earlier.
1-The MView was created without identifying that after what interval it will be fast refreshed.
2- How to Manually refresh it. Does it support On Commit, I think it is not.
3- Where should be we make a group and then add the table to that group and refresh that group.
Should this group belongs to the Master Site or to MV site?

View 3 Replies View RelatedI have to create a materialized view for a table which does not have index on any field.
While creating a Mview i am getting an error "TABLE DOES NOT HAVE THE PRIMARY KEY CONSTRAINT".
application developers do not want to create an index on the base table onto which MView is to be created.
is there any way to create a materialised view for the table without index, or is it necessary to have the index on the base table before creating MView on it.

How I can create a Materialized View without having any data in it.
For e.g.
I create a Materialialized View based on a View.
CREATE MATERIALIZED VIEW test_mv
REFRESH FORCE ON DEMAND
AS
SELECT * FROM test_view
In the above case the data fetched by the view test_view gets stored in the Materialized View test_mv. Suppose I want materialized view test_mv to get created with all the columns of test_view but not the data. I will refresh the materialized view test_mv later for data as and when required.
What shall I do for immidiate formation of materialized view test_mv without data.

Im doing some create view and create procedures for my work.In creating view, its just done perfectly.with create procedures work, I got some problem with the result.
So here is the coding:
create or replace
PROCEDURE "USP_EDW_CASH_MARGIN"

result_cursor OUT TYPES.cursor_type
)
[code]....
After i run this coding.
I got these errors :
1)Error(46,5): PL/SQL: SQL Statement ignored.
2)Error(46,5): PLS-00394: wrong number of values in the INTO list of a FETCH statement
It says that the error is with this code "FETCH v_cursor INTO v_row;"
I am not able to find any information regarding inserting data with timestamp format without putting the date.
This is what i want to do:
ALTER SESSION SET NLS_TIMESTAMP_TZ_FORMAT='DD-MON-RR HH24:MI TZR';
I create the column data type as timestamp with time zone. This is value i have inserted:
Insert Into TEST Values('05-OCT-2013 01:00 +08:00','05-OCT-2013 23:00 +08:00','SCIENCE);
And now i wish to display it in 'HH24:MI TZR' only after i deduct both of the time. This is the view i have created:
Create View TESTRECRDS As Select (STARTTIME- ENDTIME)*24 As DURATION, Science;
But when i select it display as weird timing because it would default in 'DD-MON-RR HH24:MI TZR' format.
BUT IF i create the view and display as 'HH24:MI TZR', it would gives me error:
Create View TESTRECRDS As Select To_Char(STARTTIME- ENDTIME, 'HH24:MI TZR')*24 As DURATION, Science;
Error would be invalid number. How can i display only 'HH24:MI TZR' after subtracting?
I'm stuck on the CREATE VIEW part and the SELECT statement to get the output of the CREATE VIEW. We were instructed not to use AND and simply use JOIN on this exercise.

My DBA gave me a table with only one date column say Table1.Date. Its in the format of Date and say it is = 7/23/2012.
Now i have to create my own Reporting View(which is used for reporting) based on that date column like below:
It should be a column with values in the following format =
2012-07
2012-06
2012-05 etc....upto
2010-01
So i started out my creating like this:
select
to_char(Table1.Date,'yyyy-mm')
from Table1
Union
[Code]....
.and so on till i get 2010-01.
there has to be a better way to do this.
