A view is nothing more than a stored query, change the query and you change the view.

3 column vertical view

So i am switching over from Outlook '03 to Mail 2.0. In outlook I could have a three column vertical view of my mail. this would be great on MacBook with its widescreen. It maximizes the number of emails listed by spanning from the top to bottom of the screen and lets one read more on an email with out scrolling.

20% + 20% + 499px = ?
You can't mix measures like that. Try replacing 499 with 60%.
Your float
will now drop in all browsers. Why?
20% + 20% + 60% = 100%
But the borders and padding you've assigned are added to the
width,
resulting in another mathematical improbablility. The easiest
way to fix
that is the remove the padding and borders from the main
boxes and then
nest content boxes inside the main boxes. Assign your borders
and
padding to those nested elements.

Drop Column Field and Drop Row Fields in the Details Field area in the Cube Browser of BIDS/SSDT 2012

Hello. When I right click a cube in the solution explorer and click browse, I am presented with a Details field area which doesn't have "Drop Row Fields" area like in BIDS 2008, and doesn't have "Drop Column Fields" area like in BIDS. It just has one details
area with the message "Drag levels or measures here to add to the query".
How do I include the "Drop Row Fields" area and the "Drop Column Fields" area in this Details area so it can be like 2008?

Shutdown hangs after drop column

Hi,
We were trying to drop column on a very big table, after that we cancelled that operation, and given shutdown immediate command.
Now shutdown is taking too much time, going on from last 9 hours.....
We want to start the database, what can be the best possible solution.
Shutdown abort and startup will help ?
Thanks
Dilipkumar Patel.

We were trying to drop column on a very big table, after that we cancelled that operation, and given shutdown immediate command.I guess SMON was doing rollback the transaction when you cancelled the operation. Since it was a big table, it was taking lot of time.
Can you check the alter log is there any error or info msg in it?
I am afraid if you give shutdown abort, may cause serious issues.
Before you execute 'shutdown abort', make sure you have good backup, in case of recovery.

How to Use Column Selector View in Reports

Hi all,
Can someone please advise on how to use the column selector view in CROMD's reporting tool?
Whenever I add a Column Selector view, and check the Enable checkbox of a certain column, a message appears "Click the columns in the selection pane to add more choices". However there is no selection pane, and the only thing I can do within the column is input a column label.
Am I missing any crucial steps here?
Thanks.

Hi,
Choose a column as column selector by enabling the check box and click the columns that has to get into column selector in the left navigation.
On click the columns would get in one by one. After that field that you choose would be displayed in the position of the column in the report table
Typically the purpose is something like this. If you want to dynamically change the first field say by Account Type, Account Region, Account Status and see the revenue then it can be used

Dealing with errors due to newly added/dropped columns

DB version:11g
I am not sure if i have created an unnecessarily large post to explain a simple issue. Anway, here it is.
I have been asked to code a package for Archiving .
We'll have two schemas;The original schema and an Archive schema (connected via a DB Link)
ORIGINAL Schema -------------------------> ARCHIVE Schema
               via DB Link          When records of certain tables in the ORIGINAL schema meet the archiving criteria (based on Number of Days Old, Status Code etc), it will be moved ('archived') to the ARCHIVE schema using the INSERT syntax
insert into arch_original@dblink
col1,
col2,
col3,
select col1,
col2,
col3,
from original_tableThe original table and its archive table has the same structure, except that the Archive table has an additional column called archived_date which just records when a record got archived.
create table original
col1 varchar2(33),
col2 varchar2(35),
empid number
create table arch_original
col1 varchar2(33),
col2 varchar2(35),
empid number,
archived_date date default sysdate not null
);We have tables with lots of columns(there are lots of tables with more than 100 columns) and when all column names are explicitly listed like the above syntax, the code becomes huge.
Alternative Syntax:
So i thougt of using the syntax
insert into arch_original select original.*,sysdate from original; -- sysdate will populate archived_date columnEventhough the code looks simple and short, i've noticed a drawback to this approach.
Drawback:
For the next release, if developers decide to add/drop a column in the ORIGINAL table in the Original Schema, that change should be reflected in the archive_table's (ARCHIVE schema) DDL script as well. It is practically impossible to keep track of all these changes during the development phase.
If i use
insert into arch_original select original.*,sysdate from original; syntax, you will realise that there is change in the table structure only when you encounter an error(due to missing/new column) in the Runtime. But, if you have all the column names listed explicitly like
insert into arch_original@dblink
(col1,
col2,
col3,
select col1,
col2,
col3,
from original_tablethen you'll encounter this error during the Compilation itself. I prefer the error due to a missing/new column during the Compilation itself rather than in Runtime.
So what do you guys think? I shouldn't go for
insert into arch_original select original.*,sysdate from original; syntax because of the above Drawback. Right?

What advantage would it bring if i make ARCHIVED_DATE as the first column in the ARCHIVE tables?The advantage is that if you'll add a column in the future on both original and archived tables the insert statement will work anyway...

Can't drag and drop from page view

Can't drag and drop from page view to desktop even though plus icon shows up for duplicating the page. On Mac 10.9.2 Acrobat XI. I don't want to extract through the menu and associated dialogues. Its slow and cumbersome.

Hi Peterbruce,
Acrobat for Windows will let you select pages in the Pages panel and drag them to your desktop, but that isn't an option in Acrobat for Mac OS. You can drag thumbnails from the Pages panel in one doc, to the Pages panel in another, however.

Thumbnails in Column & List views

My Finder (v10.4.5) mostly does NOT show the thumbnails of my JPGs in Column & List views, unless those JPGs were created on my computer (Tiger 10.4.6).
I got it to finally show the thumbnails in Icon view (View > Show View Options > Show Icon Preview + All windows), but I also want to see the little thumbnails in Column and List Views. Anyone know how to do this.
NOTE: those same JPGs that don't get the thumbnails on my MAC, do show thumbnails on my crappy-*** Windows ME Dell's Explorer.
By the way, (different Question) is there a way I can set up to be notified via email when somebody replies to my question here in this discussion area?
Thanks,

With a Finder window open in Column view, when you go to the View menu item and select Show View Options there are not any "Show Icons" or "Show preview column" selections for me to check.
That is very very strange. Try opening a Finder window, have it in icon view, and the bring up Show View Options, I presume you are getting the options? Now go to View (don't close the options window!) and change to List. A different set of options should appear in the options window, and if you then change the view to Column what happens to the options window?
If you want to see thumbnails for files that don't have them you either use Column view with a preview column set to display icons, or put the folder in Icon view. The Mac OS Finder does not create thumbnail.db files, as does Windows (I believe many Linux window managers create analogous files). Instead the Finder either reads the thumb from the resource fork of the file (most--maybe all--Mac graphics programs have always had the ability to create custom icons that are a part of the file), or else it will create a thumb "on the fly" for files that don't have them if told to do so in Icon and Column views. In List view it will display a small icon if the file has one, otherwise it just uses the generic icon. Windows is incapable of reading Mac resource forks, where the custom icon is for files created on a Mac, and the Finder is incapable of reading Windows thumbnail.db files. Any file you create on your Mac with a Mac graphics program will have a custom icon, if you set the preference of the program to save the file that way. This includes Image Capture, if you use it to transfer files from your camera. Images you get from a Windows or Linux box, or download from the Internet, do not have a resource fork and so do not have a custom icon.

Drop Column

Hi,
We have a table of size above 500GB. To satisfy some business need there was a requirement to drop one column. The column needed to be dropped contained huge data. Hence before dropping the column it was made unused and then we tried to drop the same. At this point we are facing some issues. The drop unused column has been executed before 18 hours and till now it is not completed.
Suspecting some discrepancy the session conducting the drop command has been killed. Now the table could be described but we are not able to select the table. I am providing the steps followed so far.
First the column was set to unused:
SQL> alter table table_name set unused (column_name);
At some later time the drop command had been executed:
SQL> alter table table_name drop unused columns checkpoint 1000;
The above statement was running for last 18 hours and till now not completed.
Then the corresponding session was killed.
After this the table could be described but select operation could not be performed and returned the following error:
ORA-12986:
columns in partially dropped state. Submit ALTER TABLE DROP COLUMNS CONTINUE
The above command was also executed but without any sign of completion and again killed.
DB Version: 10.2.0.3.0
OS: Sun Solaris 10
Environment: DWH
Kindly guide me at this point on how to resolve this and made the table available to the user.
Thanks in advance for your valuable time.
Regards,
Joy

According to the documentation you don't have many options:
CHECKPOINT Specify CHECKPOINT if you want Oracle Database to apply a checkpoint for the DROP COLUMN operation after processing integer rows; integer is optional and must be greater than zero. If integer is greater than the number of rows in the table, then the database applies a checkpoint after all the rows have been processed. If you do not specify integer, then the database sets the default of 512. Checkpointing cuts down the amount of undo logs accumulated during the DROP COLUMN operation to avoid running out of undo space. However, if this statement is interrupted after a checkpoint has been applied, then the table remains in an unusable state. While the table is unusable, the only operations allowed on it are DROP TABLE, TRUNCATE TABLE, and ALTER TABLE DROP ... COLUMNS CONTINUE (described in sections that follow).
You cannot use this clause with SET UNUSED, because that clause does not remove column data.

Hello,
I read about how to drop column from a compressed table - first set it unused and then drop the unused columns. However, in the example below on the database I ran it, it does not work. Please, can you tell me WHEN this approach does not work. What it is dependent on - parameters or something else. Why I cannot drop the unused columns?
And the example along with the errors:
create table tcompressed compress as select * from all_users;
> table TCOMPRESSED created.
alter table tcompressed add x number;
> table TCOMPRESSED altered.
alter table tcompressed drop column x;

As you can see even after altering the table by setting the column X as unused I still cannot drop it by using DROP UNUSED COLUMNS.
Thank you.

check this link it might help. At the end it has also mentioned of a bug check the same.

Cannot drop column from table owned by SYS

Hello everybody,
How can I drop a column of table which is owned by sys? thanks!
Result as follows:
SQL> ALTER TABLE HELLO_TB DROP COLUMN NUM;
ALTER TABLE HELLO_TB DROP COLUMN NUM
ERROR at line 1:
ORA-12988: cannot drop column from table owned by SYS
newbie v

You can not 'change' the ownership.
You can, however, 'move' or 'clone' most objects by exporting and importing. As follows:
I create a table under SYS (shudder).
I then export it
- using userid SYS in this case,
- under normal circumstances I'd either use a DBA account or the owner's userid
- since I want a table, I use the TABLES option - a list is comma separated and in quotes
I then import it using a 'userid' switch - fromuser & touser options
- in this case from SYS to HR
Finally, I verify it was transported.
