removing duplicate rows from a table.
We have the following table:

Name Null? Type
------------------------------------------------------------------------ -------- ------------------------
PERSON_POSITION_HISTORY_ID NOT NULL NUMBER(10)
POSITION_TYPE_ID NOT NULL NUMBER(10)
PERSON_ID NOT NULL NUMBER(10)
EVENT_ID NOT NULL NUMBER(10)
USER_INFO_ID NUMBER(10)
TIMESTAMP NOT NULL DATE
We found out that few person_id's are repeating for a particular event (3):
select PERSON_ID, count(*)
from person_pos_history
group by PERSON_ID, EVENT_ID
having event_id=3
and count(*) > 1
order by 2
PERSON_ID COUNT(*)

If we look at the 1st person id "217045", we can see that it is repeating 356 times for event id 3.
SSD@ermd> select POSITION_ASSIGNMENT_HISTORY_ID, POSITION_TYPE_ID, PERSON_ID,EVENT_ID, to_char(timestamp, 'YYYY-MM-DD HH24:MI:SS')

356 rows selected.It is safe to assume that the person id/event id with the earliest timestamp is the one that was loaded 1st, hence, the one we want to keep and the rest should be deleted.

I have a question related with VIEWS
I would like INSERT data in a VIEW with a INNER JOIN, like this example:
CODECREATE VIEW MYVIEW (order_id,list_price,customer_id) AS
SELECT order_id, list_price, customer_id FROM ORDERS o
INNER JOIN PRODUCT_INFO p ON (o.order_id= p.pdt_id);
INSERT INTO MYVIEW VALUES (4,500,10); /* will cause an error*/
But when I try to execute the insert statement, the "SQL Developer" returns a error:
ORA-01779 - "cannot modify a column which maps to a non key-preserved".
Why can't I do it? Are there some way to do it?

In a table i have some duplicate rows
I can get it through this query : select PARTY_ID from XXWFS_CUSTOMER_EXT group by PARTY_ID having count (PARTY_ID) > 1;
Now for the records which i got for each duplicate row i want to update the second row with a specific value.. so that duplicate rows does not exist anymore
Ex: I got party id's 12, 14, 16, 18 two times each
Now as 12 is two times.. i want to update the second row of 12 with some x value same is the case for other values like 14,16, etc
how can i write a procedure for this
I have a view and in that view i need to remove duplicate rows from output. For that i need to run select query in where clause of view if select query return true then we need to execute second condition.
my requirement in view like
And..........
And ((select count(*) from table A where conditions)=1 )then name is null
AND
in that code first we need to check first select query condition then we need to apply name is null condition. but i tried to run it but select query not run properly. because tables is used in View.
I have a table:
Name
_____
Smith Street
Smith Street
John Street
Ed Street
Ed Street
Ed Street
and need to assign sequence numbers only when the record (Name) changes, e.g. :
Name Seq
_____ ____
Smith Street 1
Smith Street 1
John Street 2
Ed Street 3
Ed Street 3
Ed Street 3
I have experimented with row_number partition but then i just get the sequence returning to 1 when the name value changes.
If I grouped the records by Name I would like to have unique, sequential numbers: 1, 2, 3 but where there is the same name I would like the sequence to stop and the number to replicate?
I want to delete the duplicate rows in a table without using ROWID.

I have one table in which I want to restrict some records from being inserted. I don't want to put any checked constraints. e.g. consider following table
transaction(
id number primary key,
txn_date timestamp(7),
payee varchar2(40),
amount number,
memo varchar2(40),
ref_num number
)
I want to write SQL which should not inset duplicate record.
e.g.
I have written one as bellow:
insert into transaction
select 1, to_date('2009-12-12','YYYY-MM-DD'), 'Payee1', 12, 'Test', 212 from dual where
(select count(*) from transaction where txn_date=to_date('2009-12-12','YYYY-MM-DD') and
payee='Payee1' and amount=12)=0;
Can I use exists/not exists, which query will be more appropriate. (Please consider that fields which I am using to filter out the duplicate transactions does not contain primary key.)
Can I write such SQL. Or do i check for duplicate rows one by one and then filter the duplicate records.
My requirement if id, join_date, join_time, result of table1 is matched with table2 at least one time then if repeating rows associated with the id should not come.Here is the test case.

select
[code]....
The table has about 30 milion records and holds persons names, addresses, personal id (id), and internal id(actionar_id) and date when a new adress has been added.
The view is about getting only the most recent info for one person (actionar_id).
if i run a
a) select * from actionari a where a.actionar_id = 'nnnnnnn', result is returned immediatly, oracle uses index and does not do a full table scan.
b) select * from actionari a where a.actionar_id in ('nnnnnnn','mmmmmm','ooooooo'), result is returned immediatly, oracle uses index and does not do a full table scan.
my problem when i use this view in a join.let's assume i have another table with no more than 500 records, something like
create table SMALL_TABLE
(
actionar_id NUMBER(10) not null,
......
);
and if i run
select *
from SMALL_TABLE s
join actionari a
on a.actionar_id = s.actionar_id;
it takes like forever to process, forever means 1~3 minutes.by looking at the execution plan, oracle does a full table scan, creates the view for all unique 7milion persons, and only then joins the result with the actionar_is's in the small table and returns the desired 500 record result.i am using oracle 10g.

What would cause Oracle to insert duplicate rows into a table? Could a join of two tables in the initial query assigned to an application page cause ORacle to insert an extra row into a table when an update to data value occurs? I have no insert triggers and no foreign keys assigned to the table. I am not sure what would cause Oracle to assume that an insert of a row must occur. I want to prevent that insert.

I have problem with merging rows into view. I have created "INSTEAD OF" triggers on the view for insert/delete/update of rows. However, the merge is not working and it needs rowid to work. Is there any way how to make MERGE working here ? I must use merge, because I am changing the structure of database used for large java application. And it uses tons of merge commands,changing them to insert/update is inefficient because of development-time and of course resulting execution-time.
