Problem dropping column in sqlplus.

I write
alter table u_gotobank drop column u_bacdamnt;
and it says i'm missing a key word at column.
what could be the problem?

Jens, I don't think that's the problem :
SQL> desc test10
Name                                      Null?    Type
X                                                  NUMBER
Y                                                  CHAR(1)
Z                                                  CHAR(1)
W                                                  CHAR(1)

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.

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?

Problem with columns in the middle of my book

I am writing my second book with Pages 2.02 and have run into a problem with columns. I want to add a long list of items as a list with check boxes for readers to check off. If I paste in enough text for three or four pages of two columns it gets messed up in various ways - the text flows into the following text if I don't use section breaks at the end instead of layout breaks, if I use section breaks it solves that one, but if I add anything to the list it changes all the columns across the pages so that one or several of the pages has way less in the right column than in the left. So far the left column fills the entire page all the time, but the right column has lots of spaces. If I switch back and forth from one column to two, it fixes it. If I add text before the list section it messes everything up again and because there is a section break I end up with a little bit of text on the last page and a huge gap before the single column part that follows.
Does anyone know how to get reliable results that will not mess me up when adding content before the list or in the list itself?
PowerBook G4 Mac OS X (10.4.8)

Hi Cymru,
Thank you for thinking about my problems. I guess I s half asleep when I posted and it didn't make sense.
I have so far 77 pages of the book divided into several chapters via section breaks. Inside the 5th section there is almost two pages of paragraphs. Those paragraphs could become 3.75 pages or who knows how long before the list of items. The list of items is 226 items separated by carriage returns and go from one word with 5 characters to 7 words and 34 characters. It needs to be a list with check boxes before them so that the user can check off the items that apply. It is a workbook about turning bipolar into an advantage and is currently 8.5 x 11 and printed on my laser printer for now, but when completed will be more like 8 x 10, so it needs to resize without major hassles.
I have tried every combination of breaks to get the list to flow in two columns, but perhaps have not done the correct combination. I show invisibles and layout. At the end of my paragraphs I do a paragraph return. I then do either a section break or a layout break, followed by a paragraph return and another layout or section break. I then put my curser before the paragraph break, but after the first section/paragraph break, and set columns to 2, evenly divided by default with 3.2026" columns and .3375" gutter, but I want them to change with page size in the future.
Once set up, I copy the text out of BBEdit and paste into the left column. It takes up several pages because it is formatted to do double spaces, so I use one of my styles to make it bold and single spaces. I then apply list style with image bullets and one of the default box images that came with Pages. There are 5 items in each column on the first page because it is close to the bottom, but flows into the next two pages. (with text edits it might end up 20 items in each column on the first page) The second page has 39 items in each column and the last page has 8 items in the left column only, but if with section breaks take up the whole page and the next paragraphs start on the next page. If I then add items to the list, every page gets messed up and the second page ends up with 39 on the left column and less items in the right column for each added item.
If I use layout breaks instead of section breaks, the paragraphs following my lists (now with only one column) end up under the list. What that means is I can see my bold items, but beneath them are my paragraphs that belong after the list. I can see the layout break at the end of the list, but the columns that are shown as part of the 'view layout' are visible right over the single column text also for the rest of the page. The only way to solve that is to go with section breaks and put up with the gap from the end of the list to the following paragraphs.
I hope this makes more sense.

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.

To see the content of a BLOB column from sqlplus

Hi,
I have a table which has a BLOB column.
The blobs are text files.
Is there a way to check the content of blob column from sqlplus itself.
Thanks.

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...

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;

That error usually means it is still mapped, maybe it is used in another interface if you say the mapping has definitely been removed.
You can expand the datastore > Used In > "As a Target" or "As a Source" or "In a Package" - that should tell you if it being used anywhere else.

HOWTO drop column from Designer instead of warning

Hi,
is there possibility to tell designer to generate scripts for dropping columns that are no longer in repository? I'm using Designer 6i.
Thank you,
Radek

This functionality is not available in Designer at this point. The decision not to drop the column was in order to try to preserve data integrity.
However, as the database now allows you to do this, we have decided to add this functionality to Designer. In the short term you will need to
update your DDL scripts manually, but we hope to bring you this functionality automatically from Designer by the end
of this calendar year or early next year in a maintenance release.

Thanks for the answer.Its there any issue you face to just drop and add new primary key in your setup i.e. you fear that volum is high and dropping and adding back would take time?

Hi,
DB version is 11.2.02.
We have table which is range partitioned and sub-partitioned by list.
Table is also compressed.
When I try to drop a column, I get error.
