Add the new column on 25 million lines TableHi gurus,
I have to add the new column to a populated application table who get to each Transaction.
We can do this with no interruption of service and what are the things that I need to look after adding the peak of performance.
Something happened to my mind is re - run stats
Database version = 10.2.0.4
OS = RHEL4
I appreciate your help on this
If the GET of the table is locked, it means that the application cannot write any new transactions in the table until the new default values has been updated?, my understanding of the downtime to do this to
*-Online Yes, you need downtime in 10 g *.
Another Question if we have default values as NULL will always be the table get locked?
*-ONLINE YES *.
11 g, this problem has been fixed by oracle: http://www.oracle-class.com/?p=1943

How to add the new column in existing table to our desired location?
For example, I have to add the new column 'course' before the salary column in the emp table.
I think the best way is to add the column at the end of the table and create a new view with the order of the columns...
places the data into a temporary table and recreate the table with the correct order of the columns, and then insert data to the table from the temporary table
CREATE TABLE temp_my_user LIKE)
SELECT * FROM password);
DROP TABLE password;
(Password) CREATE TABLE
, first name VARCAHR2 (25)
, middleInitial VARCHAR2 (1)
(, name VARCHAR2 (25));
INSERT INTO password (userID, firstName, lastName)
DROP TABLE temp_user;
I need to add the new column to a datablock and display the newly added column in the form. What are the steps I need to follow.
1. I chose the new column from the view to the datablock.
2. Add the text element in the layout editor. But this position is not correct. It overlaps with another column. How to add the new column to the layout editor?
In the layout editor, you can simply drag the fields so that they do not overlap.
My already deployed ADF application and entry into service.
I would add three columns of data.
I worried that if I have does not add the new column and will redeploy again, it will have an effect at my request.
Anyone here ever face with a kind of this problem
As the General best practices. You do not direct operations on the ACTIVE database rather test the application in the test environment.
on the other hand if your column is NOT NULL then it will affect your application otherwise no impact
My table looks like Fallows.
Select * from company
PRODUCT_ID COMPANY_ID COMPANY_SHORT_NAME COMPANY_LONG_NAME 1 1001 An Inc. Long name A Inc. 1 1002 B Inc. Long name B Inc. 1 1003 C Inc. Long name C Inc. 2 1004 D Inc. Long name D Inc. 2 1005 E Inc. Long name E Inc. 2 1006 F Inc. Long name F Inc.
My requirement is I would LIKE to add A NEW COLUMN AS COMPANY_LOCATION NEXT TO COMPANY_SHORT_NAME
How to get there.
I tried like Fallows alter company table add company_location varchar2 (100) after company_short_name;
but this query shows the error
ORA-01735: invalid option of ALTER TABLE
If the query I've tried is correct?
Give me your suggestions.
Thanks in advance.
As long as you're on 11 GR 2 or lower, it will not work.
There is no Clause "AFTER"in the alter table do not add column."
You have the chance to use dbms_redefinition (when no interruption of service is possible) or manually create a new table with the columns in the order you need and then migrate the data and then drop the original and rename a new.
In case you are already on 12 c, you have a chance to add the column to the end and then make visible columns and invisible status in the right order. This way your column will get to the position that you want it to be.
Select entered_on_date as START_DATE
where entered_on_date > = ' 01-SEPT.-10'
entered_on_date ASC order
which works very well.
you want to put the new column entitled late...
If closed_date is > resolution date fill in the column 'late' with 'Y '.
If closed_date < resulution date fill in the 'overdue' column with "n".

You can add additional code to deal with closed_date = resolution_date and if are NULL, but it's a start:
CASE WHEN closed_date > resolution_date THEN 'Y' WHEN closed_date < resolution_date THEN 'N' END overdue
Have you added a new element of the new column and set the source type on DATABASE_COLUMN then the value from the source to your new column name?
I have a search page when I search on this page with a few criteria
It shows a region of array type on what it shows all records in the db, that match this search criteria
now, I want to add a column at the end of this table on the EBS page that displays
and I want to show some value related to this record that is displayed on this table
How can I get this value db linked to some folder basis
and how do I set new column at the end of the table?
Here are the steps you need to perform.
1) go to the page with this region of the table. Click on this link page
(2) check the name of the VO attached with the region of the table and click
(3) in this page, you can see all of the attributes that are present in the original Version
(4) if the new attribute you want to display exists in the vol. note his name.
(5) create a new column in the region of the table through customization and attach this attribute VO with her as well as the view Instance.
If this attribute does not exist in the original Version, then you must go for the extension of the VO.
It could be useful!
I am new to OBIEE and I already searched here in the forum but have not found an exact answer which could help me.
I have a table in the warehouse where to get information on employees. It's employe_id, manager_id and name.
Employe_id Manager_ID name
2 1 Meier
Now, I would like to create a new column in the Mapping BI Admin tool business layer and add a SQL where to select the name of the Manager.
Is this possible? And how can we do it? It will work with a new logical column? Where we add the SQL Code?
I hope someone can answer my question!
Thank you very much!
OK, I think I got it - the name of Manager is on a separate table (or a search to return to the current table) and your thinking that you want to label your SQL in the report to find the name of Manager based on Director ID, you have?
If so, import the table with the names of Manager in the physical layer. If this is the same table that you already have (but want to search him in the current table) then you need to create an alias for the current table.
For each new table in the Phy layer, or an alias - define the join (current_table.manager_id = manager_table_or_aliased_current_table.employee_id)
Once completed, we will on the source of the logic table in the MDB for this dimension, edit, on the general tab, "Add" and select the table / alias that you created in the phy layer. Click OK - it combines now two tables attached as a source - you can then map the name of the Manager search in your column 'name '.
Hey guys, I have a question for you novice. I read 4 analog channels and write all four of them in a file in four columns. A part of my program is counting the number of digital ups (TTL) and indicating a ' cycle count "with a shift register. I want to put this ' cycle count ' as a new column in my data file, alongside the other 4, preferably in the first column. I tried to connect the County directly to the VI measures, but it is not separating in his own column... ideas?
I made a few standard on oaf page customizations.
I added 2 new columns to the existing table, but they were added at the end of the table.
But I want a column to be the first and a column in the middle of the table.
How can I achieve this?
Please give me your valuable suggestions...
Customize page, there is another icon for just before reorganization create icon.
You can use and organize all the elements in the region of the table according to your requirement.
I have added a field defined by the user on the screen to create organization. (For example, country-> ACT_UDF_COUNTRY).
Now, I want to display in the search for organization window. (i.e. when clicked on the image of research organization field on the form to create a user, the research we receive).
Currently, this research only display the name of the company. I want to display two columns. for example, company name and country.
I try to edit the file FormMetaData.xml and
< attribute name = "-2"label ="request.requestDetail.organization" displayComponentType = "LookupField' variantType = dataLength 'long' = map ="Organizations.Organization "50" name">
"< lookupMethod ValidValues ="findOrganizationsFiltered"operationClass ="Thor.API.Operations.tcOrganizationOperationsIntf"= displayColumns" Organizations.Organization Name, Organizations.Status, * ACT_UDF_COUNTRY * "selectionColumn ="Organizations.Organization name"/ >
< / attribute >
But it did not work...
You'll want to do the following:
1. create a list of choices for the type of field with the domain being your UDF name and the name of the search as Oraganizations.Country.
2. change your view columns in the post you made to be Organizations.Country.
3. put to update your xlWebAdmin_en_US.properties for any country you use and in the section "LOOKUPFIELD column headers" add an "lookupfield.header.organizations.country" entry = Country
Restart your IOM and it should now show.
sname name sid
CCC 3 C
4 DDD D
5 EEE E

I have a form of LCD with a table in it. Im trying to simply add a new column to the table. The option is there, but the column appear just after clicking Add the column to the left. I selected a column, right click the space > insert > column to the left. But the habit intsert. The object table properties tab shows lines and colum numbers, but they are grey.
It is a dynamic array, where a new line can be inserted using a button. Is that the dynamic nature of the question? ID hate to cancel all the flow dynamics and programming just to add a column, and then reapply them all.
You do not add the columns in the object > palette (screenshot 2) of the Table. I suspect that the problem is that it is not enough on the page (in the content area) to add the column. In the screenshot 1, if you look at the width of the column highlighted from the space to the right of the table, you will see that a column can be added due to restrictions of space.
Reduce the width of the column highlighted (temporarily), and then add a column. Once added, you can resize the columns to match the width of the page.
Hope that helps,
