View 5 RepliesHow to set default value of particular column of a table ?
View 5 RepliesI would like to add a constraint "default value" for a table column, with a name.
I know how to do it for a constraint "not null" : ALTER TABLE tablename MODIFY columnname CONSTRAINT constraintname NOT NULL;
But I don't know how to do it for a constraint "default value".How can I do ?
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.
I am trying to write a script to create a table with the author column default value as "Administrator" I use this execute immediate statement1;
Why does it create the table successfully with ',AUTHOR VARCHAR2(30) DEFAULT 1' and NOT with ',AUTHOR VARCHAR2(30) DEFAULT Administrator' ?
I want to set the COLUMN DEFAULT have to "Administrator" when I create the table.
When I try character I get this error "ORA-00984: column not allowed here"
statement1:='CREATE table TEST_ID2'
||'(TEST_ID NUMBER(6)'
||',test_name VARCHAR2(40)'
||notnull||
',date_created DATE DEFAULT SYSDATE '
[code]....
how do I add a column to an existing table which when rows are added to the table this column will have the same default value?
alter table thetable add (new_column_name varchar2(100) default bbubu);
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" ?
Oracle RDBMS version : Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production

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 created a IR report and I set the default search column using the suggestion found in the thread URL....but how can I keep this default even after the research was done?Now it is resetted !

View 11 Replies View RelatedI 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.
Is there any way to use * along with the default value while selecting on a table...I need something as follows:
select *, 'JUNK' from table_name;
(or)
select 'JUNK', * from table_name;I know it will not work.

i have two questions.
(1) how can i fill some value in a table column based on some existing column value automatically without user intervention. my actual problem is i have 'expiry date' column and 'status'. the 'status' column should get filled automatically based on the current system date. ex: if expiry date is '25-Apr-2011' and current date is '14-May-2011', then status should be filled as 'EXPIRED'
(2)hOw can i build 'select' query in a report (report 6i) so that it will show me list of items 'EXPIRED' or 'NOT EXPIRED' or both expired and not expired separately in a single report based on user choice. 'EXPIRED' & 'NOT EXPIRED' can be taken from the above question no. 1.
I am trying to update currency column of one table using the currency column of other table using the following sql code.
update ODS.SO_ITEM OSI
set CURRENCY__CODE=(select currency__code from sa_sales.SO_ITEM SSI where SSI.ID=OSI.ID)
This update is taking taking a lot of time and is never ending.
should i create index on source table (SA_SALES.SO_ITEM) or on target table (ODS.SO_ITEM) ?
How to add column 'col_new' in below table after the column 'col1'?

if a table contains two columns and both are part of the primary key of that table (Kind of obvoius).
should i opt for a index organized tbale in this case ?Or should i opt for another running sequential colum which would serve as a primary key of this table and define the actual two columns of the system as unique keys.
there is a drawback if a most of the tables of a database contain composite primary keys?
I am trying to join column names from a table with data from a different table. I think i should be able to pass the parameter to a 'select list' in a query. Look at my sample data below. And the data in sales table can grow till 15 rows and similarly corresponding columns in saleshist.
CREATE TABLE SALESHIST
(
PRODUCT VARCHAR2(30 BYTE),
Q1 VARCHAR2(30),
Q2 VARCHAR2(30),
Q3 VARCHAR2(30),
Q4 VARCHAR2(30)
)

I have a requirement as to find all the tables and columns containing keyword "SELECT" in my database. I followed forum
Re: How to find the column name and table name with a value
But when i run the below query on 11.0.2g Oracle Database

column_name,
:search_string search_string,
result
from (select column_name,

I have two table country and state.Columns are given below
SQL> DESC Country
Name Null? Type
----------------- -------- --------------
PRIMARY_KEY NOT NULL NUMBER
DISPLAY_ORDER NOT NULL NUMBER
NAME NOT NULL VARCHAR2(50)
TREE_POSITION NOT NULL VARCHAR2(250)
PARENT_ID NUMBER
SQL> desc state
Name Null? Type
----------------- -------- -------------------------
PRIMARY_KEY NOT NULL NUMBER
DISPLAY_ORDER NOT NULL NUMBER
NAME NOT NULL VARCHAR2(50 CHAR)
VALUE NOT NULL VARCHAR2(50 CHAR)
TREE_POSITION NOT NULL VARCHAR2(250 CHAR)
PARENT_ID NUMBER
Now I have to insert the values in the state table taking from the country table.
EXAMPLE :
INSERT INTO STATE (PRIMARY_KEY, DISPLAY_ORDER, NAME, VALUE, PARENT_ID, TREE_POSITION) VALUES (251, 1, 'Alaska', 'AK', 233, 'STAT_USUS_AKAK');
but here the tree position is static it can be anything at the client side so I want to make it dynamic. So to make dynamic what I have used is mentioned below:
INSERT INTO STATE
(PRIMARY_KEY,DISPLAY_ORDER,NAME, VALUE,
PARENT_ID,
TREE_POSITION)
VALUES
[code].....
Now I want that Quote: select tree_position from L_STATE_ITEM where name ='United States')||'_ALAL' which i have used in the state table to put value in the tree_position, I want to make the other half part after the concatenation operator "_ALAL" also dynamic.
So I was just wondering If I can pic that value from the "VALUE COLUMN" of the same table.
I want to use default value in pl/sql , i'm executing below code
SET serveroutput ON
DECLARE
l_deptno INTEGER DEFAULT 10;
v_dname VARCHAR2(200);
[Code]...
SQL> @test.sql
Enter value for deptno: 40
dname value=OPERATIONS
I tried with NULL to use its default value but it uses NULL(which does make sense)
SQL> @test.sql
Enter value for deptno:
error
How to use the default value of the passed argument?
expected O/P
dname value=ACCOUNTING

Only the values inside are needed. Is there any way to achieve it using Pl-Sql or just using Sql ?
