Change Default Value Of Certain Column In A Table In Oracle 11g
Aug 18, 2013
I have a table called cust_file, his table consists of a lot of columns (one of these columns called cus_tax) and have a lot of data,I use oracle 11g, I want to change the default value of the column cus_tax to be equal 1, I wrote
ALTER TABLE cust_file MODIFY(cus_tax DEFAULT 1); table alteredbut
after I inserted new data to test the operation, I found that the new record has a value
= null for the column cus_taxthen
I tested using the following query select
data_default from all_tab_columns where table_name='CUST_FILE' and column_name='CUS_TAX'; no rows selected...
Change the default value of the column cus_tax.

As per the bellow the default XML storage has been changed in 11gr2.
docs.oracle.com/cd/E11882_01/appdev.112/e10492/whatsnew.htm
Quote:
Oracle Database 11g Release 2 (11.2.0.2) New Features in Oracle XML DB
The following Oracle XML DB features are new in Oracle Database 11g Release 2 (11.2.0.2).
Default Storage Model for XMLType
The default XMLType storage model is used if you do not specify a storage model when you create an XMLType table or column. Prior to Oracle Database 11g Release 2 (11.2.0.2), unstructured (CLOB) storage was used by default. The default storage model is now binary XML storage.
We have a application which works fine on r1 but not on r2 due to this change, we are going to investigate resolving the issue on the application in the future, in the mean time we need to be able to use the CLOB storage.
Does any one know where we can change this functionality back to the pre 11gR2 change?

I'm using Oracle 11g enhanced ADD COLUMN Functionality. Adding new columns with DEFAULT values and NOT NULL constraint no longer requires the default value to be stored in all existing records.
Sometimes we change DB columns from NOT NULL with DEFAULT to NULL with DEFAULT. This operation "materialize" column default. Is there an easy way (Dictionary view) how to find, that COLUMN default value is stored as metadata or is "materialized" ?

Application Express ver. 4.1
I have created a form. Some of the elements are hidden such as updated_by and update_date. I have provided the default values for these attributes as pl/sql expression in the "default section" (Application->page->edit page item). I am using the Process Row process that is automatically created when a form is created.
The problem is when I click the update button, the updated_by and update_date is passed as null values which throws an error from the database.

I have a table as below. This table is not partitioned.
create table t1
(
d1 date,
n1 number not null
);
[Code]....
I took an export dump of the above table and after that I renamed the table t1 to t1_old. Then I recreated the table as below with a default constraint on d1 field.
create table t1
(
d1 date default to_date('01/01/1100','DD/MM/YYYY','NLS_CALENDAR=GREGORIAN'),
n1 number not null
[Code]....
But the problem here is the data import is taking too much time than what I expected. I can't afford a maxvalue partition here as of my DBA team mentioned if you add maxvalue partition adding partition later in a stage is difficult on this table
apply in this scenario and make the import faster. I am using oracle 10.2.0.1.0 version.

I have to change the datatype of a column from CLOB to varchar2, without changing the order of the columns. The table has no data.
I could find any other way other than dropping the CLOB columns and then adding new columns with varchar2 datatype. But this changes the order of the columns in the table.
