ORA-22856: cannot add columns to object tables

Oracle 9i
==========
I tried to alter a table using a simple script.
ALTER TABLE tablename ADD col VARCHAR(50);
And it gave me the error: -
ORA-22856: cannot add columns to object tables
Can someone give me some direction on how to resolve this? The script executes fine on a test env.
Thanks in advance

Thanks for replying...

Excuse the incomplete column names. All datatypes are basic ones and there are no constraints defined on any of the columns (dw env). The table is partitioned.

Hi Rajnish,
I had the same issue. For what it’s worth I was able to do a workaround basically creating all the columns when I create the table. The following code works for me to create the table which is just a matrix with one Integer column as the key and the rest as type Double.
It is not ideal in all scenarios because the table columns cannot be added dynamically via a procedure at a later point. This table has 27K columns now
Of course one of the advantages of a flex table would be programmatically adding columns dynamically. This works, but maybe there is still a way to add columns dynamically from a procedure, and someone else can advise.
Apparently dynamically adding columns via procedures may have some "minor" limitations due to the need to compile the procedure with knowledge of the flex table DDL. But again, hopefully someone knows another solution.
Best regards,
Mark

OWB Issue|| ORA-12838: cannot read/modify an object after modifying it in

Hi
I am not able to enter the data into the staging table .

but it is giving me an error in that
ORA-12838: cannot read/modify an object after modifying it in parallel
Can you please help me in tthis case.

Hello,
The error ORA-12838 occurs if you try to issue SELECT/DML immediately after completing parallel DML, within one transaction - it's not permitted.
Start another transaction - issue Commit or Rollback first.

IDM with SQL server Error: Cannot find columns for the table...

Hi all,
I am Configuring IDM with SQL Server repository and ran into this error.
'Cannot find columns for the table 'object'
.....jdbc...[SQL Server]Invalid object name 'object'
Can anybody please help me!!
G

Yes, permissions are very important. I ran into a similar problem because I didn't have the correct permissions. Make sure the user has the following permissions:
CREATE ANY TABLE
ALTER ANY TABLE
DROP ANY TABLE
CREATE ANY PROCEDURE
EXECUTE ANY PROCEDURE
DROP ANY PROCEDURE
Also, make sure there is enough space in the default tablespace of that user.

Ok, connect to auxiliary intance and post
show parameter db_create
show parameter control_filesIn your pfile, Have you mentioned single quotes?
If your database with OMF then if you give it as below. as there is some work around

The comments are in german but the structure should be clear I think.
Any help appreciated!

Unfortunately it's a bad idea to store your code samples (or screenshots or whatever) on an external site, because not everybody can get access to such sites, especially if their workplace has limitations on websites that can be visited.
you're pastebin.com is one such site that I cannot access, so I can't see your code.
If you want to paste code and/or data on the forums remember to put the tag: {noformat}{noformat} before _and_ after it, so that the formatting is maintained and it's easier for us to read.

How to add columns for existing table dynamically?

Hi,
I created table structure only. I want to add columns for this existing table. Columns are not fixed, according to the user choice i need to write code.
Plz give me reply asap.
Thanks
Shirisha

Hi Shirisha,
I think the following code snippet will help you.
int l_no_cols = 0;
//Get the number of columns in this variable, something like the following
//l_no_cols = wdContext().currentContextElement().get<Context_attribute_name>;
IWDTable l_tab;
IWDTransparentContainer l_tbl_cont = (IWDTransparentContainer)view.getElement("TableDataCont");//ID of Container
l_tab = (IWDTable)view.getElement("TableData");//ID of Table
l_tab.setVisible(WDVisibility.VISIBLE);
l_tab.bindDataSource(wdContext.nodeTable_Data().getNodeInfo());
for(int a = 1; a <=l_no_cols; a++)
//Creating the column
IWDTableColumn l_tab_col = (IWDTableColumn)view.createElement(IWDTableColumn.class,"COL"+a);
//Creating Caption for Column Header
IWDCaption l_tab_cap = (IWDCaption)view.createElement(IWDCaption.class,"Caption"+a);
l_tab_cap.setText("Col"+i);
l_tab_col.setHeader(l_tab_cap);
//Creating Table Cell Editor for column
IWDInputField l_tab_cell = (IWDInputField)view.createElement(IWDInputField.class,"CellEditor"+a);
//creating context node attribute for the column dynamically
wdContext.nodeTable_Data().getNodeInfo().addAttribute("Col"+i,"com.sap.dictionary.String");
l_tab_cell.bindValue(wdContext.nodeTable_Data().getNodeInfo().getAttribute("Col"+i));
l_tab_col.setTableCellEditor(l_tab_cell);
l_tab.addColumn(l_tab_col);
l_tbl_cont.addChild(l_tab);

I need add column in a table

can someone tell me how can i add a column in a table somewhere in midle, i don't won't this column at the end of table. this table already have about 500 rows. the column i am adding it is null. can someone tell me how can i do that without losing any data.
i am using oracle 9.2.0.7
Thanks

the question is there is a way to do it instead of investagating why and so.... Well, it was for you to investigate actually to ponder on the question if it is worth it.
Anyway, I did provide you the way you would do it, if you do decide to do it.
Did you read till the end of the post?

How i add Columns to my table ?

Guys, im not being able to add my columns to the table, can anyone help me ?
Thanks!
TableView<String> tv = new TableView<>();
tv.setVisible(true);
       TableColumn firstNameCol = new TableColumn();
       TableColumn lastNameCol = new TableColumn();
       TableColumn emailCol = new TableColumn();
       tv.getColumns().add(0,firstNameCol);

Woah! Thanks man! it works greatly but.... Theres just 1 more issue!! i read all the javaDoc and asked help to a friend but we were unable to find a solution, also, im using the "Introduction to javaFX 2 book".
Im sorry to keep troubling you guys, but it seems javaFX isnt taking off here, and i sometimes think im one of the first in Brasil to starting learning it.
They teach java in my College, but i think javaFX is a way better "swing/interface" than the one in java. Anyway , the problem im having is : I need get the data from a db , no problem with that, but how can i insert that data? I tried several solutions but none worked.
Can you help me one more time :D ? Please!!
thanks a lot guys

Add columns to a table with lob column

Hi,
Just a quick question: is there a performance penalty after adding columns to a table with a lob fied? the lob field is now the last column in the table and via via I was told that adding columns will impact badly the IO performance on the table if the lob field isn't anymore the last column. The table is on a Oracle 10.2.0.3 version.
thanks. regards
Ivan

Havent heard of performance degradation specifically due to a LOB column not being the last column in a table (although there are several issues with just having a LOB column in a table).
You may want to build a test database to test it out. It should be easy to run tests comparing one with the additional column and one the original to prove or refute it. The results would be interesting to learn - please post them up if you intend to test it out.

ORA-30036 when modifying column in large table

Oracle version 10.2.0.4
Afternoon everyone!
I have a large table that I need to modify a column in - increasing from CHAR(3) to CHAR(6)
On altering the table I'm getting an ORA-30036: unable to extend segment but 8 in undo tablespace
Increasing undo tbs size isn't really an option, and I don't really want to go copying the table elsewhere either - again due to space limitations.
Is there a way to avoid this undo exhaustion? Will disabling logging for this table solve my issue? Or is there another way similar to the 'checkpoint' clause you can use when dropping columns?
Many thanks!
Adam M

Just in case nothing better appears and you can't increase the UNDO ...
1. Create a new table with the correct datatype
2. Insert data from the old table to the new table, in batches if necessary. Divide the data by key values if possible or get a range of rowids to process or something
3. Make sure dependent objects are created for the new table
4. drop the old table
5. rename the old table to the new table

ORA-22856: cannot add columns to object tables
