Is this a bug? create view lost a comma and succeeded

Is this a bug? create view lost a comma and succeeded.
oracle 10.2.0.1.0
try the following sql.
create table test
id int,
dataa varchar2(20),
datab varchar2(20)
insert into test values(1,'a1','a2');
insert into test values(2,'b1','b2');
insert into test values(3,'c1','c2');
create view vtest
as
select id,dataa
datab
from test;
--it should be error but successed
select * from vtest;
--and dataa gone!
drop view vtest;
drop table test purge;

No it's not a bug, Oracle will treat "datab" as alias to "dataa" if comma left out.
Doesn't your view has two columns id and datab, but datab column showing dataa data?

I have updated my iPhone 3s to the latest software. I had backed up my phone before I did this. Now I have lost my music and apps. I can't sync the phone with my Mac, I can't re-download as the phone says I don't have any music or apps available. Help!

I have updated my iPhone 3Gs to the latest software in an attempt to iron out a problem with a new telephone network provider (Tmobile). I had backed up my phone before I did this. Now I have lost my music and apps. I can't sync the phone with my Mac, I can't re-download from iTunes as the phone says I don't have any music or apps available to re-download although it all shows up on my Mac. The music and app content cannot be restored when I try to restore the phone from the back up I madeon my Mac. Help!

Working on that now. I'm just getting frustrated that everytime I run updates for the phone I end up with tech problems that I have to spend time solving as opposed to updates that actually improve my usage. Now I will once again get to spend hours reloading my phone all for updates that didn't affect my usage in the first place.

Creating View based on Current and previous data from same table

I am trying to create a view based on a table called “my_companies”. The table has following columns: “company_id”, “start_date”, “product_type_code”, “partner_id”
The main purpose of this view is to obtain previous company_id’s associated with a particular “partner_id“and “product_type_code”. So basically, I’m looking to create an extra column, say “prev_company_id” in the view along with all the other columns. The “previous” data can be obtained depending on the “start_date”. I’m not able to write a query successfully to do this.
Can anyone help? Thanks in advance.

Hi,
Whenver you have a question, it helps to post:
(1) The version of Oracle (and any other relevant software) you're using
(2) A little sample data (just enough to show what the problem is) from all the relevant tables
(3) The results you want from that data
(4) Your best attempt so far
Executable SQL statements (like "CREATE TABLE AS ..." or "INSERT ..." statements) are best for (2).
Formatted tabular output is okay for (3). Type before and after the tabular text, to preserve spacing. The sample results should include any special cases that you foresee, such as one company having many previous companies, or vice-versa.
It sounds like might need a +self-join+, where you have two copies of the same table, as if the current companies were in one table and the previous companies were in another, even though they are all actually in the same table.

Create View without inbound, outbound and navigation link

Please look at this picture:
There are:
+ PanelView
+ View 01
+ View 02
+ EmptyView
In the PanelView, there are two buttons, button01 and button02. When press on button01, it shows View01; when press on button02, it shows View02.
Problem is:
How to do above things without creating inbound, outbound and navigation link.
Thank u a lot.

Dear Mr. Raghunandan Madarikuruva ,
Everything is very easy if there are inbound, outbound, and navigation link.
What happen if there isn't inbound, outbound, and navigation link.
My problem is how to open each childview without inbound, outbound, and navigation link.
How can I do that
Thank you for answer my question.

How to Create a View of a Query and assign it into my web template?

Hi All,
I need to create 3 views for my query and show that on my web template. I have never done this before. Can you please let me know step-by step procedure to create views for a query and how to show it on my WAD report?
Thanks,
Satyam

Hi Satyam,
Include the Dropdown Box web item in your web template. In the Web Item Parameters tab, select the Data Binding type as Query View Selection. Assign the Dataprovider from Selection of Query Views button below the Data Binding Type. You also have the option to Display Specific list of Query Views or all views based on that Query. For this you have to choose Selection of Query Views button. Here you can turn on Specific List of Query Views checkbox and select the Views depending on your requirement.
Regards,
Hari.

Create view structure based on table

Hi,
I've got two tables one spec table containing a table num, column name and column length. For example:
Table num             Column name         Column length
1                    client_id                          8
1                    client_name                    15
1                    client_gender                   1
2                    order_num                       4
2                    order_date                       8
...and one data table containing multiple records with table num and data for each table num defined in spec table. For example:
Table num          Data
1               12345678Ben Anderson   M
1                75486923Evy Jans       F
2                123420/05/07
2                000117/04/07
...How can I create a script to create a view for table num '1' based on the strucure defined in the spec table and containing the data of table one that is stored in the data table?
Thanks.
Regards,
Ken

Assuming that the spec table has a column position column then given these tables:
SQL> SELECT * FROM tab_spec;
    TAB_ID COL_NAME                          COL_LEN    COL_POS
         1 client_id                               8          1
         1 client_name                            15          2
         1 client_gender                           1          3
         2 order_num                               4          1
         2 order_date                              8          2
SQL> SELECT * FROM tab_data;
    TAB_ID DATA
         1 12345678Ben Anderson   M
         1 75486923Evy Jans       FA procedure along the lines of:
CREATE PROCEDURE make_view (p_tab_id IN NUMBER,
                            p_view_name IN VARCHAR2) AS
   l_sql   VARCHAR2(32767);
   l_start NUMBER := 1;
BEGIN
   l_sql := 'CREATE VIEW '||p_view_name||' AS SELECT ';
   FOR r IN (SELECT col_name, col_len
             FROM tab_spec
             WHERE tab_id = p_tab_id
             ORDER BY col_pos) LOOP
      l_sql:= l_sql||'SUBSTR(data,'||l_start||', '||r.col_len||') '||
              r.col_name||',';
      l_start := l_start + r.col_len;
   END LOOP;
   l_sql := RTRIM(l_sql, ',')||' FROM tab_data WHERE tab_id = '||p_tab_id;
   EXECUTE IMMEDIATE l_sql;
END;should do the trick. Note that the owner of the procedure will need to have the CREATE VIEW privilege granted directly and not through a role.
Having done this, I must reiterate what others have already said. This is a spectacularly bad idea. Rather than creating a view, I would change it to generate a CREATE TABLE statement to dump the data into proper tables.

Purpose of Creating View

Hi Experts,
Good Noon.
Am new to OBIEE,and in the learning stage..a quick question !!!!Can you tell what is the purpose of creating VIEW in OBIEE? And what all VIEWS we can create in OBIEE?
Hoping for a prompt response.
Regards,
Rishi.

Hi ,
creating views let you to test new columns(calculated or not ) new tables (you can merge several tables in one view) before applying the changes on the database .
sure it stills not performer like a physical table but somtimes like in my case when you don't have full access on the database it stills the only solution that you have .
Sincerly

Plz help me create a Procedure with create view cmd

i want to create a view from the procedure like the following one,

     ffdt date;
     ftdt date;
begin
     select to_date(fin_fr_dt,'dd-mm-yyyy') into ffdt from dual;
     select to_date(fin_to_dt,'dd-mm-yyyy') into ftdt from dual;

end;

vu as select a.amt from cbtran a where chq_dt > ffdt
and chq_dt <ftdt';
end;Hallo,
your problem is , that execute immediate does't recognize ffdt
You have to concatenate literals
create or replace procedure asho2005.mock_pro( fin_fr_dt in date, fin_to_dt in date) is
ffdt date;
ftdt date;
begin
select to_date(fin_fr_dt,'dd-mm-yyyy') into ffdt from dual;
select to_date(fin_to_dt,'dd-mm-yyyy') into ftdt from dual;
execute immediate 'create or replace view mock_vu as select a.amt from cbtran a where chq_dt > '''||ffdt||''' and chq_dt <'''||ftd||'''';
end; BTW, your view doesn't return any rows
ffdt and < ffdt :-)
Besides that , it's a very very bad method!
You must not create views in runtime. Use of literals results in hard parsing .
The performance will be poor.
You have to create view in design time, and then simply use select:
select * from mock_vu where chq_dt > (your_date) and something else

HT1449 After moving music and movies from my MacBook Air to an external hard drive, do I create a new iTunes music and media folder on my computer then add more music and movies, then will I be able to move the computer music/media to the hard drive musci

I need to move the music and movies from my MacBook Air (original) to an external hard drive, after I do this, do I create a new music folder and media folder on my computer to load music/movies in via the dedicatd external drive and then would I be able to move the newly imported to the external drive which would be my main site of storage?

No, do it all in one go and henceforth only use the library located on the external drive.
iTunes: How to move [or copy] your music to a new computer [or another drive] - http://support.apple.com/kb/HT4527
Quick answer if you let iTunes manage your music: Copy the entire iTunes folder (and in doing so all its subfolders and files) intact to the other drive. Start iTunes with the option (shift on Windows) key held down and guide it to the new location of the library.

Pages 5.5.1: When opening a document created with Pages '09 (Version 4.0) with Pages 5.5.1 the page header and the page footer are deleted. How can this be prevented? Or is this a bug in Pages 5.5.1?

Same problem here (no graphics in header or footer) and the problem has been reported months ago. It is another bug/feature lost when Apple moves from 09 to the iCloud-compatible versions. Complain to Apple, you may have better chance than me and they may finally listen to their users....

Is this a bug? master rowid value lost when saving on a master/detail form

master/detail forms seem to lose the rowid after saving, if the unique identifier is set to ROWID
to reproduce the problem:
1) create a master detail form on DEPT/EMP
-- choose 'Managed by Database (ROWID)' on the 'Define Primary Key' page.
-- do not include master row navigation (but i don't think this matters)
-- choose 'Edit detail as tabular form on same page' on the 'Choose Layout' page
-- include the master report
2) on the master/detail page, change the conditional branch that returns to the master report page
-- the normal condition for this branch is request in SAVE,DELETE,CREATE
-- change it to request in DELETE,CREATE
3) run the form and save a change
-- saves fine, session shows the ROWID value is still set
4) save a second change
-- change does not save, form reverts to Create mode
this problem does not occur when using the primary key columns instead of rowid
see http://apex.oracle.com/pls/apex/f?p=60813:7 for the ROWID version
see http://apex.oracle.com/pls/apex/f?p=60813:11 for the PK column version

Hi Saverio,
Bug *13563808* has been logged to track the reported issue, and a fix will be made available in a future release. Just to clarify, this issue is only arising when the APEX-generated Master-Detail is modified post-generation, so for users who have not modified their Master-Details using ROWID to manage their DML processes, they should not experience this issue.
In relation to my workaround, my suggestion works in my test environment, which I verified before posting the initial suggestion. Please note that the 'Reset Page' process is, by default, conditional on the "Delete" button being pressed. If you have made further modifications to your Master-Detail page, then this might explain why you're seeing different behaviour to me. You might using the "Debug" option on the Developer Toolbar useful. Viewing the debug information should help you to decipher what's going on/wrong on your page. If you still can't resolve the issue, then the safest option might be to revert the page back to it's original state, meaning the user navigates back to the Report page upon submitting changes to the Master-Detail Form page.
Regards,
Hilary
