Updates In Audit Table
May 22, 2011
I have to create a audit/history table on a master table so that I can store the old/current state of data in my audit table. I am planning to write following program.
1. Created the audit table with similar number of records.
2. Everyday at a particular time I will compare the audit/main table and push the records in audit table which are either updated or not present in the audit table so that the audit table = main table + old state of data.
I am unable to figure out the proper way to implement the point 2 above in oracle database.

Check the below simple sql stmts:
create table tab_tab(col1 number, col2 number);
insert into tab_tab values(1, 1);
insert into tab_tab values(2, 2);
insert into tab_tab values(3, null);
[code]......
My question is why the table content didn't look like:
col1 col2
----------
1 2
2 2
3 2
4 3
5 4
I thought that when oracle will update 1st, 2nd & 3rd rows then the sub query will get a count equal to 2, but the time when it goes to update the 4th & 5th row the sub query should get back a count equal to 3 & 4 resp. BUT that is not what exactly is happening!!

I was given a task by manager to keep track of changes on a given table including os_user who made it.Should I create a trigger on it (on any update, insert, delete etc.) or there is a better way of doing it ?I think there could be some info already in some data dictionary views or something like it.
If I CREATE MATERIALIZED VIEW LOG on that table.

We need to audit what data has changed from Vendor_B table when compared to Vendor_A table.
There is two tables:
a) VENDOR_A
b) VENDOR_B
VENDOR_A and VENDOR_B table does not share the same structure but have 1 column in common - the ID and may or may not having changed Coordinates.
We need to audit what coordinates has changed from Vendor_B data when compared to Vendor A and get the report back in the format of:
<pre>
VENDOR_A VENDOR_B
ID Change_date LONGITUDE LATITUDE LONGITUDE LATITUDE
873 1/02/2013 -33.46711315 151.3195056 -33.46211316 151.3245057
694 3/02/2013 -33.46721315 151.3198056 -33.46214312 151.3265053
</pre>
---------------------------------------------------------------------------------------------------------------------------------------------------
--Found a sample query from Ask Tom but I am not sure how I can apply them to get the structure above.
---------------------------------------------------------------------------------------------------------------------------------------------------
<pre>
create table base_tab (pk number, column1 number, column2 varchar2(30), column3 date);
Create table refresh_tab (pk number, column1 number, column2 varchar2(30), column3 date);
Create table diff (pk number, column1 number, column2 varchar2(30), column3 date, base_tab number,
refresh_tab number, action varchar2(30));
[Code] .....
--clean out the differences table
truncate table diff;
--------------------------------
-- build the difference data
------------------------------------
insert into diff select pk,column1,column2, column3,
count(src1) base_tab, count(src2) refresh_tab, null action
from
( select a.*,

I'm trying to create a trigger that will come into play after the user has inserted a 0 for the booking evaluation, i need the booking id sent to the audit table. This is what I have tried so far:
CREATE OR REPLACE TRIGGER zero_evaluation
AFTER INSERT OR UPDATE ON booking
FOR EACH ROW
WHEN (NEW.Evaluation=0)
BEGIN
INSERT INTO audit (audit_id, booking_id, Reason)
VALUES (audit_id_seq.NEXTVAL,:NEW.booking_id, 'Contact customer for 0 evaluation');
END;
I get the following:
Line 2 PL/SQL: SQL Statement ignored
Line 3 PL/SQL: ORA-02289: sequence does not exist
This is my SQL statement:
CREATE TABLE audit
(audit_id numeric(5) not null,
booking_id numeric(5) not null,
[code]...

I am just making a audit table as well. i have learnt the basics from here URL.....
My problem is that after inserting into audit table if i issue commit command then the table + unsaved data present on the form is also saved.What i want is that i issue a command which save only inserted record in audit table, and should NOT save data present on the data entry form. (which will be saved later by other method/button).

I support to get a handle on statistics collectionn in their data warehouses. It seems developers have created several ANALYZE TABLE jobs but the code for these is not stored as PLSQL in the database and thus it is problematic for statistics collection. Even if we collect stats that way we want, these jobs kick in and overlay the statistics we collect every day.
Is there a way to AUDIT ANALYZE TABLE? I can't find it anywhere.
Is there a way to globally turn of ANALYZE TABLE in a 9i database?

You have a stock_amt value in one table and there is a procedure that updates and substracts from this stock_amt.
lets say in a store a have a stock amount of 50 items and this procedure, for each sale is subtracting from this value and it is not allowed to go below zero. The process, beside the update, on this column (set stock_amt = stock_amt - x) is doing a lot of other updates on other tables and it total it takes like 0.5 seconds. Everything is fine till I want to execute this procedure by 50 users in parallel.
The initial implementation, to avoid some dead locks and we put a lock on that column (stock_amt) but there where to much waits. we cannot hold that lock for 0.5 seconds.
What will be the best approach for this? For this stock amt problem, maybe the solution can be a trade like: do not update that column every time but once in a while, by another process or by a materialize view logic.
but what if my column is a critical value like a Prepay balance or bank balance and it needs to be updated in near real time. What will you do?

I have a table of records with a date_modified column. I would like to simply report the count of updates made each week. For example, given:
Record Date_Modified
155291141/23/2013
157277201/24/2013
152619321/25/2013
142263211/28/2013
140043421/28/2013
150050431/28/2013
148315761/29/2013
154364281/31/2013
148066382/1/2013
[Code]...
I would like to return:
Week Updates
43
57
69
77
84
Although in place of the week number, providing either the value for the last day of the week or the first day of the week would be just as good.
how to go about this task.

The updates occur always that a significantly change was done? (Like create, rename or drop datafiles and tablespaces)
Or the RMAN catalog owner must issue "resync catalog" frequently?

Consider the statement below:
Update employee e
set e.dept_id = (select d.dept_id
from dept d
[Code].....
The above is not the exact code which I am executing but an exact replica of the logic implied in my code.
Now, when i display the value of 'rows_updated' it returns a value greater than 0,i.e 3 but it should ideally return 0
since there are no records matching for the condition:
(select d.dept_id
from dept d
where e.dept_name = d.dept_name)
So, I executed the statement:
select count(*) from employee e
where emp_id = 1234
and exists
(select 1
from emp_his ee
where e.emp_id = ee.emp_id)
and the result was 3 which is the same value returned by %rowcount.
why this is happening as I am getting incorrect values in %rowcount for the number of rows updated.

I have a table of 3 columns:
SQL> show user
USER is "ANDREY"
SQL>
SQL>
SQL>
SQL> --create the table:
[code]...
I insert rows into it:
SQL> --fill it with data:
SQL>
SQL> insert into a(key1 , key2) values (1 , 1);
1 row created.
SQL> insert into a(key1 , key2) values (1 , 5);
[code]...
i want to perform a logic by which:for every distinct value of key1 - values of key2 will be checked in all records holding that particular key1 value, and update the key3 field to 'inactive' where the key2 value for that particular key1 is the highest in number.
i've found out that i could do it by an SQL statement:
update a
set key3 = 'inactive'
where key2 = (
select max(key2)
from a a2 where a2.key1=a.key1
);
however I wanted to use the cursor to "load" the max key2 values FOR EACH distinct key1 value exists in the table,and do the same thing as the update statement above WITH A CURSOR,So tried and wrote the following:
SQL> create or replace procedure proc1
2 IS
3
4
5 var1 a.key1%type;
[code]...
unfortunately, it works only for one row, and i don't understand what's wrong, I executed, and checked what has changed:
SQL> exec proc1;
PL/SQL procedure successfully completed.
SQL> select * from a;
KEY1 KEY2 KEY3
---------- ---------- ----------
1 1 active
1 5 incative
2 24 active
2 21 active

Is this the correct forum to ask questions about Oracle CPU's?
I ran the CPU-JUL-2012 on a workstation for version 11.1.0.7, got Return Code 0 and "OPatch Succeeded".
Yet a Retina scan ran after shows no change....?
I've tried reading the availability document, but I have no experience at Oracle patching.

This problem went away for me in 4.2, but I am limited to 4.1 in production. The problem is this: I have three editable columns in my Tabular Form
1) I make a change to column 3 and press submit. The values in columns 1 & 2 (that were not changed) are overwritten with null during the update (submit). Column 3 is saved correctly.
I deleted my tabular form and re-created it thinking that I may have trashed something. But it appears that is the way it works. How do I prevent the unchanged editable columns from being overwritten with nulls?

I am attempting to perform regular updates on several Oracle tables. The scripts performing the updates are scheduled to run every two minutes, get a value and update the table with that value.
The value doesn't always change but the scripts will still attempt to perform an update.
The same script is part of 7 objects, all of them are scheduled to run at the same time. They update the same table but never the same row.Even though the script is mostly the same on the 7 objects, they run completely independently of each other. The first object will usually perform the update without any problems but when it comes to the second object the script will time out.

How to update a form fields which taking a searched value from another table .
I have a form that records student data and which has a drop down to select the 'student registration No' that comes from different table.
When insert or update a student record, first we select the student registration No from drop down to see if he is an existing student.
If he is already registered student then relevant student name and other details should be shown in the form and should be able to enter few other details as well.

I need to list all AUDIT command issued.I'm using the DBA_STMT_AUDIT_OPTS view, but it doesn't list all of them.
For example if a run this command:audit create session by my_user;
the DBA_STMT_AUDIT_OPTS will list it. But if I run this command:audit select on my_user.my_table;
The DBA_STMT_AUDIT_OPTS list only the first.
Why the DBA_STMT_AUDIT_OPTS doesn't list the second audit command?How can I track all the AUDIT commands issued?
