Alter view

hi
how can we use alter view to update view by coding in vb.net thanks

"alter view to update view" could mean many things. Here are a couple of interpretations:
(1) Redefine a database view to retrieve different data.
Don't.
Unless you're writing an application that will maintain database structures, this isn't something you should be doing from application code. Indeed, the account used by your application should not have any database permissions to do this. Work
with tables, views, etc., but don't change them.
(2) Change the permissions on a View so that you can perform Updates through it.
Don't.
See (1).
Also, some views retrieve data from many tables, making it impossible use them in this way.

Altering Views in Oracle 10.2

Hi,
I have a requirement that we need to change code of some views before running some daily batches (part of the code is not required for running the daily batches) and then revert back to the original code once the daily batches finish. Instead of using alter view command daily, I though about creating a new view for the modified code which will be used for running the batches and just swap the names of the two views before running the daily batches and then revert back after batches completion.
Any suggestion on this?
Thanks,
Younis

Instead of modifying the view, why not have 2 different Views and a Synonym for the "correct" view. The Application Code references only the synonym and you have "pre-Batch" and "post-Batch" commands to drop and recreate the Synonym to point to the "correct" view. That way, no objects get invalidated !

2 select 'HEMANT' as owner, object_name, object_type, created

Transactional Replication: Alter view changes are not reflect on Subscription database

Hi All,
we are configured transactional replication in our environment on sql server 2008 R2 , Yesterday I made a view alter on publisher database the view also present in replicated articles but unfortunately the changes not reflect in subscription, I already have
checked the : Replicate Schema change option in Subscription option its also true, there is not latency exist in replication monitor , i have checked the blocking on subscription and publication. one more thing I tested the changes on replicated table its
working fine
Please help me to fix the issue.
Regards,
Pawan Singh
Thanks

Hi Pawan,
According to your description, the alter on the view in publication doesn't be reflected in subscription database. As my analysis, the issue could be caused by that the distribution agent job doesn’t run after altering the view.
I make a test on my computer, and set up transactional replication to replicate tables and views. Firstly, when creating subscription, I set the distribution agent job ‘Run continuously’(as the screenshot below), and alter the view in publication database,
then the change is successfully reflected to the corresponding view in subscription database.
However, I also make another test with setting the distribution agent job ‘Run on demand only’(It is determined by you), and find that it is not reflected to subscription database unless I run the distribute agent job manually.
The distribution agent is used to read the updated transactions written to the distribution database and applies the change to the subscription database, so please check if your distribution agent job runs after you alter the view. If not, please run the
job and check if the issue still occurs.

Michelle Li

Option to alter view of conversations in Messages gone

As per the title, in Mavericks you were able to alter the way that conversations displayed in Messages, you had a choice of three options via the View menu. In Yosemite, that option in the menu has gone and the only way to view conversations is the speech bubbles look á la iOS, I preferred one of the other views when viewing Messages on a desktop .

for the Points
It does seem that the general push to make the OS more like iOS does lead to this situation where something that worked and was understood no longer fits that criteria.
I think most people would understand that a Computer version of something is capable of offering more.
In Messages (and ichat before that) you used to be able to Format Text chats. ( It is still possible, to a lesser extent that earlier versions, but you have to go to System Preferences > Accessibility and Reduce Transparency then Restart Messages) The standard Preferences Pane and Format Menu have been removed.
The iOS version can apply any sound that is on the iPhone or iPad to a particular Contact when they "call " in various apps.
This is no longer possible in Messages on the Mac.
It does seem that in an attempt to streamline various interfaces to match the two OS versions that functions are being withdrawn.

Why does sp_Refrehview revert my altered view to an older version?

Last night I altered one of my views. Where I work, it is custom to run sp_refreshview after changing any views due to the sheer number of views utilized at my job. I noticed that after I altered my view and after I ran sp_Refreshview, the view had changed.
The view no longer reflected the changes I had made in my alter statement last night. Why is this happening? I looked online and couldn't find much information. Any thoughts/tips/ideas would be greatly appreciated. Thanks

My guess is it was not properly altered or schema/db was different

GRANTS to execute ALTER VIEW .... COMPILE

Hi,
We're developing a system to remote distribution of oracle objects like VIEWS, TRIGGERS, PACKAGES...
In Oracle we have a special user to create any of this objects in any schema of the database.
In order to verify the status of the object recently created, we execute a ALTER OBJECT ... COMPILE, but when we try to compile a VIEW an error of insufficient privileges raises us.
Which most restrictive roles we have to give our user to do this operation.
Thanks in advance.
Javier

Hi,
According to Oracle documentation the limitation is as follows:
* view must be in your own schema or
* you must have ALTER ANY TABLE system privilege.
http://download.oracle.com/docs/cd/B19306_01/server.102/b14200/statements_4004.htm
Why not do select status from all_objects to see the status of the view (if it's valid or not)?

How to find that who has altered a view.

Can any one know how to find "*who has altered view in database?*" like user name, machine name or even OS user name nay thing atleast one of them if not all.
When I checekd with
SELECT last_ddl_time FROM all_objects where object_name = :object_name,
I found its altered 5 days back.
Any help would be appreciated.
Thank you.

Hi,
The only way to achieve it is that you PREVIOUSLY audited that view.
You can do that for the next time using the following procedure.

How to have rownum in a report based on a view

How to use rownum in a report or tabular form?
I wanted to number the rows in a report. The most obvious way would be just stick
rownum in there. There is a view in a database1. It is merely select a,b,c from various
things joined together and order by pkey1.
Apex is in database2 so I have to create a view there across the link
like:
create or replace view SOME_VIEW as
select * from OTHER_VIEW@SOMELINK
alter view SOME_VIEW add constraint PK_SOME_VIEW
PRIMARY KEY (pkey1)
DISABLE NOVALIDATE;
The problem is if I try to include rownum in the query in the report I always get:
failed to parse SQL query:
ORA-01446: cannot select ROWID from, or sample, a view with DISTINCT, GROUP BY, etc.
There's no rowid, it knows that the primary key is Pkey1 so what is the problem?
I know it's rownum that it hates. Maybe I can just number these things some other
way. However it'd be good to figure out what it is griping about.
Anyone know?
Edited by: lake on Mar 12, 2011 9:36 AM

thanks!
Actually I made a mistake in testing. And it does work to do this:
in database1:
create or replace view VIEW1 as
select
rownum "SEQ", etc.
in database2:
create view VIEW2 as select * from VIEW1@mylink
How I screwed up testing that I don't know. I was calling the column NUM before....
this is good because you can create a report about the next so many of something, such as how many of
the next batch of mailings have address problems? For that you need to know in what order it will be done and
when to quit.
But I'm sure I will use the report rownum thing also. thanks very much.

Running a query in a View Designer results in an error, but running the same query in a Query window works

Hi everyone,
Just as my title says, I have a query which I've written in a query window and it works perfectly.
But when I try to add the query code into the view designer, it throws a Syntax error.
Error in ON clause near '('.Unable to parse query text.
Also, when running the query from the view designer (pressing red exclamation mark) I get a different error.
SQL Execution Error.Executed SQL statement: SELECT Sku, ParentSku, UPC, ...Error Source: .Net SqlClient Data ProviderError Message: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.
Has anyone else experienced this and is there any workaround?
I have tried to create the view with T-SQL (CREATE VIEW etc.), but when opening it in the view designer I get the error from the 1st image.
Thank you,
Radu

Hi Radu,
Yes, I have faced similar issue. I had a View and it was working totally fine but when once I opened it in via right click - View Design, it was giving parse error.
Cause is that Query designer parse and executes the query without error but the way View designer works, it can't parse it.
Later I ignored View desinger and just used T-SQL like CREATE/ALTER view.
Workaround is to do right click on View - Script View as - CREATE To/ ATER To.
Regarding Timeout error, again the issue with View designer which couldn't execute query in there and ended up with timeout error.
If your SELECT query and SELECT * FROM YourView works fine in Query designer, you are good to go.

Problem in view

if i have view like
create or replace view v_emp as (select * from emp);
and now i drop one column from emp; i.e View become invalid
how this view become valid 'I already tried alter view v_emp compile but return error

You need to understand how oracle stores the view definition.
SQL> create table test (col1 varchar2(2),col2 number(2), col3 char(1));
Table created.
SQL> create view test_view as select * from test;
View created.Lets see the definition stored by oracle.
SQL> ed
Wrote file afiedt.buf
1* select view_name,text from user_views where view_name='TEST_VIEW'
SQL> /
VIEW_NAME                      TEXT
TEST_VIEW                      select "COL1","COL2","COL3" from testSo, even you have created with *, oracle stored it with all column names like "SELECT COL1,COL2.." not "SELECT
* FROM TEST"
Now if you drop a column then this will become invalid and recompilation will not work because the col you dropped is still exists in the view definition.
SQL> alter table test drop column col3;
Table altered.
SQL> select view_name,text from user_views where view_name='TEST_VIEW';
VIEW_NAME                      TEXT
TEST_VIEW                      select "COL1","COL2","COL3" from testBut if you add a column, then the view become invalid but the definition remains correct, So you can recompile that with ALTER command.

Using VIEW inside a stored procedure

Hi,
So I have a View designed in one file that validates someone who is authorized.
Then I have a stored procedure to display authorized stationeries created before a given date. Its takes a parameter @CreatedOn.
How can I use VIEW in my stored procedure so I can display all the authorized which are set 1 before a given date?
My VIEW:
ALTER VIEW vw_AuthorizedStationeries AS
SELECT Authorized
FROM dbo.Stationeries
WHERE Authorized = 1
And my stored procedure:
CREATE PROCEDURE usp_stationeries (@CreatedOn datetime)ASBEGINSELECTFROMENDGO
Thanks!

Try something like below, You need to replace CreatedDate column with appropriate date column in your table.
1. Alter the view to get the required date:
ALTER VIEW vw_AuthorizedStationeries AS
SELECT Authorized, CreatedDate
FROM dbo.Stationeries
WHERE Authorized = 1
2. Alter SP:
CREATE PROCEDURE usp_stationeries (@CreatedOn datetime)
AS
BEGIN
SELECT Authorized
FROM vw_AuthorizedStationeries
WHERE CreatedDate <= @CreatedOn
END
GO
OR
You can pull required information directly from your table:
CREATE PROCEDURE usp_stationeries (@CreatedOn datetime)
AS
BEGIN
SELECT Authorized
FROM dbo.Stationeries
WHERE CreatedDate <= @CreatedOn and Authorized = 1
END
GO

Bug: Views Disappears

I discovered quite by accident something kind of scary.
If a view is edited through Portal (3.0.8), and there is a
syntax problem, the view disappears.
Here is what I was presented with:
ORA-24344: success with compilation error(WWV-112301)
Error: Invalid SQL statement or you do not have privileges to
select from the Table/View (WWV-17138)
I will stick to other means to modify views.

Hi,
This is the way ALTER view is implemented in Portal.
Whenever you try to Edit a View, the old view gets dropped
and the new one is Created.
While Editing a View you must be careful to click on the Back
link on the error page to correct the view definition,
If you click on the return to Navigator, the original View
diappears.
This is also the case with most other Database Objects.
Thanks
