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
create table test1
( ID NUMBER(11)
,MEMBER_NMBR NUMBER(10)
,CODE_NMBR NUMBER(7)
,ROW_EFCTV_DT DATE
,ROW_TRMNTN_DT DATE

I have to update the row_trmntn_dt of first row to row_efctv_dt of 2nd row which is 30th Oct 2012 - 1 day i.e. 29th Oct 2012
This is my query:
UPDATE t_tt_hours a
SET a.sak_request = (
SELECT b.sak_request
FROM t_requests b, co c
[Code]...
The problem I am having is that it is updating all rows even when it is pulling back a null value for b.sak_request. I've tried adding b.sak_request is not null to the select statement like this:
UPDATE t_tt_hours a
SET a.sak_request = (
SELECT b.sak_request
FROM t_requests b, co c
WHERE b.nam_eds_tracking_id = c.id_dir_track_eds
[Code]...
but it doesn't seem to make a difference. The reason I need to do this is that the difference between where it matches with a valid (non-null) value is 396 rows vs. 12,484 rows which is too time consuming to run on my page.

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.
sql to achieve the duplicate removal.
The requirement is I have a table (TAB1), wherein I have 3 columns, ID, LID and STATUS.
The value in ID column = ID_SEQ.NEXTVAL,and LID will be either 0 or 1 and the possible values for STATUS are 'ED','CP', NULL. The ID column is not suppose to have duplicate values, but there is no check on the table for the same.
Someone has updated the existing data and ID column is containing duplicate values. Wherever LID = 0 and STATUS = NULL and if only if ID is duplicated then the ID_SEQ.NEXTVAL has to be assigned to ID field, so that there are no more duplicate values.
CREATE TABLE tab1 (id NUMBER , lid NUMBER, status VARCHAR2(10));
Existing Data
------------------
INSERT INTO tab1 VALUES (1,0, 'ED');
INSERT INTO tab1 VALUES (1,0, 'CP');
INSERT INTO tab1 VALUES (1,0, NULL);
INSERT INTO tab1 VALUES (1,0, NULL);
INSERT INTO tab1 VALUES (1,0, NULL);
INSERT INTO tab1 VALUES (1,0, NULL);

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.

create table table2

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.

No I need to update a new column in Table A with the value in Table B.Value where the ID's from both tables match. Problem is: When I do this I get multiple rows and hence Oracle won't let me update this column. Now, I keep reading that for these types of updates, there has to be a one-to-one relationship...
Is this true...is there anyway of telling Oracle to update wherever it finds that ID, regardless of how many duplicate ID's there are?
This is quite a frustrating problem and most of the sites that I've looked for solutions try get the query one-to-one...problem is...with my table sets it's impossible to do that - I need to update wherever the id's match (even if it return multiple rows).
I have this requirement in Oracle FORMS ver 6i where I populate some records in a table in a datablock and display them on the screen. A facility needs to be provided to the end users to select the records randomly by just entering the count of the records in a non-d/b text field. The number entered in the count field will decide how many records are to be selected randomly.
I tried using the query -
UPDATE <table a>
SET <col 1> = <value 1>
WHERE rowid IN (SELECT rowid FROM (SELECT * FROM <table a> ORDER BY DBMS_RANDOM.VALUE)
WHERE <col 2> = <value 2>)
/
which I found on the link [URL] but while compiling, the Form gives a compilation error for the ORDER by clause - i'm sure there's no syntax error in the way I have written it...
Assume that we have table Test with a column TestId and Status. This table is having 10,000 records. Now, we need to write a stored procedure that does the following:
1) Select top 10 rows whose "Status = NEW'
2) Update the selected top 10 rows with "Status = PROCESSING"
3) Return those top 10 rows.
Assuming there are hundreds of such requests coming to Oracle database, how can we make sure each request NEVER gets a duplicate record at any given point of time and how to fetch the records that have been updated individual request?
