I need to create a shell script to find the free space of an auto extensible tablespaces and send an alert when the free space is < 700MB. I tried checking with the dba_free_space, but I did not get the exact free space.
Tell me the logic to find the exact free space of autoextensible enabled tablespaces?

Is it possible to have auto stretch functionality (similar to Oracle ADF) in Oracle Forms?
The requirement is to adjust the data blocks/ canvases according to the window size automatically.
I know it is possible in Oracle ADF. But I want to achieve the similar kind of functionality in Oracle Forms.

I have written the code by using UTL_FILE package. but i am getting the output as shown in the screen shot(without formatting the column size as the width of the data it has). But I want the output column width to be set according to the size of the data automatically.

I have set up a schema using a DDL script in Oracle 10g. I am linking this through to a Visual Basic 2008 fron end. The connection is fine. My database of is for a car hire company project.
I need to know how to create an auto increment for a primary key field, like Access does.
For example here is my table structure for my Rental_Payment table.
-- TABLE RENTAL_PAYMENT
CREATE TABLE RENTAL_PAYMENT (
PAYMENTNO NUMBER NOT NULL,
CARDNO NUMBER NOT NULL,
[Code]....
So for example the first record would appear as:
PAYMENTNO CARDNO AMOUNT CARD_TYPE
======== ===== ====== =======
01
I would then enter values and the next payment number would be 02 etc.
PAYMENTNO CARDNO AMOUNT CARD_TYPE
======== ===== ====== =======
01 123412 £40.00 VISA
02
Visual Basic will usually have a star (*) beside a new entry field so 02 will be
* 02
etc........
I have about creating a sequence. So how can I tie this to my table?

insert into ot_pack_list values ('a',2,10,1);

I have given a specific user default tablespace on Users and a quota 5M. However I want to check if the user have used up 70% of that 5M. If so, I want to increase quota by 500K so in this will be an additional to the 5M. The code I wrote is overwriting the 5M I initially gave the user with 500K. Attached is a sample of the code.

I have created and role in my database and assign privileges as per following query.
Select 'Grant select on'||' user.'||object_name||' '||'to MyRole ;' from all_objects
where object_type in ('TABLE','VIEW')
and owner='username';
After granting role to new user everything work fine.I want to know a way to sync role with any newly created object.
Should I create a job that may execute above sql store results in a file and then execute to ensure all privileges are up to date for role or there any other optimal way exist ?

i tried the following update on one table:
update siebel.s_contact
set marital_stat_cd =
case
when (marital_stat_cd = 'Casado') then 'Married'
when (marital_stat_cd = 'Solteiro') then 'Single'
when (marital_stat_cd = 'Divorciado') then 'Divorced'
end
As you can see i forgot the else, so my update is wrong.
I thought i could rollback the update issuing the rollback statement, but when i have issue the rollback, the i query the table to confirm that the update was rollbacked and for my suprise the update is commited.
I didn�t issue the commit statement after the update and i confirmed that the auto-commit feature to worksheets is disabled, so i don�t understand whit the update was commited.

Is there a way to find out when a datafile for an undo tablespace with autoextend enabled actually extended? I've done a few tests, and nothing is written to the alert log or any trace file that I've found. I can't find any V$ or DBA view that will give me the history of a file's size.

Step1
CREATE TABLE test
(id NUMBER PRIMARY KEY,
name VARCHAR2(30));
Step2
CREATE SEQUENCE test_sequence
START WITH 1
INCREMENT BY 1;
Method1 Follow Step1 and Step2 and create a Trigger as below :
CREATE OR REPLACE TRIGGER test_trigger
BEFORE INSERT
ON test
REFERENCING NEW AS NEW
FOR EACH ROW
BEGIN
SELECT test_sequence.nextval INTO :NEW.ID FROM dual;
END;
/
Method 2 Follow Step1 and Step2 and directly have an insert statement as below:
INSERT INTO test (id, name) VALUES (test_sequence.nextval , 'Jon343');
Method 1, the Trigger is not getting created, however by following Method 2, I am able to generate auto-increment number.
