Duplicate Sequence Number For Identical Rows

Jul 5, 2010

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?

SQL & PL/SQL :: Rows In Table With Sequence Number

May 17, 2012

I have a table ABC with two columns NAME and SEQUENCE. The valid values of sequence are from 1..50. The table may not have all the Sequence number. For example following is the data in my table..

Quote:NAME SEQUENCE
------------------------
Jonh| 5
Amy| 1
Suresh| 3

I need a SQL to get the data like

Quote:NAME SEQUENCE
------------------------
Amy| 1
| 2
Suresh| 3
| 4
Jonh | 5
|6
|7
..
..
..
|50

Basically I want to have rows for the sequence numbers which are not present i my table. I thought of using the following query to generate a sequence and then join, but does not work.

select rownum from dual connect by rownum <=50

I tried something like

with temp as (select name, sequence from abc where supp_ref_order is not null order by sequence )
select rownum as num, temp.name from dual, temp connect by rownum <=50 where temp.sequence =num

SQL & PL/SQL :: Finding Identical Rows And Updating Records?

May 30, 2013

I need to find the identical rows in the below table based on ID column and update the previous identical record's end_date with latest record's start_date-1.

"ID" "NAME" "START_DATE" "END_DATE"
1 "a" 05-MAR-10 31-DEC-99
1 "B" 30-MAY-12 31-DEC-99
1 "C" 30-MAY-13 31-DEC-99
2 "A" 02-APR-10 31-DEC-99
2 "B" 02-APR-10 31-DEC-99
2 "C" 30-MAY-12 31-DEC-99
3 "C" 04-MAR-10 31-DEC-99

Result should be like below format..
"ID" "NAME" "START_DATE" "END_DATE"
1 "a" 05-MAR-10 29-MAY-12
1 "B" 30-MAY-12 29-MAY-13
1 "C" 30-MAY-13 31-DEC-99
2 "A" 02-APR-10 01-APR-10
2 "B" 02-APR-10 29-MAY-12
2 "C" 30-MAY-12 31-DEC-99

SQL & PL/SQL :: How To Generate Number (not Sequence Number) In Query

Mar 9, 2011

I have the following select query that works perfectly fine. Returns 25 rows based on the descending order of the price.But, I want add one more expression to this list of columns in this query (apart from customer_id).

the expression should look like Cust-01 for the first customer from the below query all the way to Cust-25 for the last customer.But how can I can generate 01 to 25 in oracle?

select customer_id from
(select customer_id from capitalPLAN
where member_status = 'MEMBER' AND customer_id NOT in ('156','201','1385','2125','3906','165')
order by price desc
)
where rownum <= 25

Sequence Number In 11g RAC

Sep 17, 2012

In our production, we have two nodes in the cluster. We use the sequence for one of the main table for primary key. Our application is expecting sequence number increments along with created date time stamp. Right now sequences are cached for each node and it creates problem for the application. We would not like to use NOCACHE option because it causes performance issue.

This is the current scenario -

Transaction #1 on Node 1 - Seq ID 1 - Time Stamp 12:01
Transaction #2 on Node 2 - Seq ID 51 - Time Stamp 12:02
Transaction #3 on Node 1 - Seq ID 2 - Time Stamp 12:03

When I try to query based on the time stamp, primary should also go up. To be very clear on what I would like to have, please consider the following example.Without using NOCACHE option, I need to have the data in the following order.

Transaction #1 on Node 1 - Seq ID 1 - Time Stamp 12:01
Transaction #2 on Node 2 - Seq ID 2 - Time Stamp 12:02
Transaction #3 on Node 1 - Seq ID 3 - Time Stamp 12:03

In other words, sequence number should always increment along with the time.

PL/SQL :: Duplicate Rows Removal

Jul 3, 2012

removing duplicate rows from a table.

We have the following table:

SSD@ermd> desc person_pos_history
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(*)
---------- ----------
217045 356
216993 356
226198 356
217248 364

[Code]...

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')
2 from person_pos_history
3 where EVENT_ID=3
4 and person_id=217045
5 order by timestamp;

PERSON_POSITION_HISTORY_ID POSITION_TYPE_ID PERSON_ID EVENT_ID TO_CHAR(TIMESTAMP,'
------------------------------ ---------------- ---------- ---------- -------------------
222775 38 217045 03 2012-05-07 10:29:49
222774 18 217045 03 2012-05-07 10:29:49
222773 8 217045 03 2012-05-07 10:29:49

[Code]...

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.

SQL & PL/SQL :: Last Sequence Number Created

Mar 31, 2011

Is there any way to get the last Sequence Number generated regardless the Sequence name? Something like dbinfo('sqlca.sqlerrd1') within Informix?

Imagine I have 2 sequences. Imagine that I run both several times until 20:00 hours. Imagine that at 21:00 hours I would like to know what was the last generated number created by any of the sequences. I don't wann know wich sequence generated the last NEXTVAL, I only want to know the value of the last NEXTVAL used.

Is it possible without mentionating the Sequence name?

SQL & PL/SQL :: Joining But Avoiding Duplicate Rows

Oct 16, 2010

I have two tables A and B

CREATE TABLE A(EMP_ID NUMBER, EMP_NAME VARCHAR2(100))
CREATE TABLE B(EMP_ID NUMBER, EMP_ATT1 VARCHAR2(10), EMP_ATT2 VARCHAR2(10))
INSERT INTO A VALUES(1, 'ONE');
INSERT INTO A VALUES(2, 'TWO');
INSERT INTO A VALUES(3, 'THREE');

[Code]....

This query returns all the matching row of A and B

SELECT A.EMP_ID, A.EMP_NAME, B.EMP_ATT1, B.EMP_ATT2
FROM A
INNER JOIN B ON A.EMP_ID=B.EMP_ID

The output for this shows:

EMP_ID EMP_NAME EMP_ATT1 EMP_ATT2
1 ONE 1ATT1 1ATT2
2 TWO 2ATT1 2ATT2
2 TWO 2ATT1.1 2ATT2.1
3 THREE 3ATT1 3ATT2

The requirement is to avoid duplicate rows even if matched:

EMP_ID EMP_NAME EMP_ATT1 EMP_ATT2
1 ONE 1ATT1 1ATT2
2 TWO 2ATT1 2ATT2
3 THREE 3ATT1 3ATT2
