SQL & PL/SQL :: Get Distinct / First Record From Jungle Of Duplicates?

Aug 30, 2010

I am trying to work with query to get distinct unique records, following is my scenerio:

DocNo |Title| Revs|UpdateTime|OBID
DOC-101|DESCRIPTION1|1|2/28/2004 11:37|6108-9
DOC-101|DESCRIPTION1|1|2/28/2004 11:36|6106-13
DOC-201|DESCRIPTION2|0|4/24/2005 16:44|7899-1

[code]...

From the above duplicates I would like to get only 1 distinct record based on latest update time (when using distinct on a sub-query since OBID is unique again returning all recds)

I am expecting results like:
DocNo|Title| Revs|UpdateTime|OBID
DOC-101|DESCRIPTION1|1|2/28/2004 11:37|6108-9
DOC-201|DESCRIPTION2|0|4/24/2005 16:47|7900-1
DOC-301|DESCRIPTION3|3|2/21/2007 7:26|6869-4
DOC-304|DESCRIPTION4|3|8/22/2007 9:31| 39208-1

Way To Eliminate Duplicates

Jun 11, 2013

I have a table like below:

tableA
aid des
1 concrete
2 wood
3 straw
4 plastic
5 fiber glass
6 other

tableB
bid material
01 1
02 2
03 3
01 2
01 2
02 3
01 5

The result I need when updating another table with this info is:TableC
edw_id bid Requirement
021 1 concrete, wood, fiber glass
032
025
123
521

I do not want :
concrete, concrete, concrete, wood, wood, fiber glass

SO far I am using the following but since I am dealing with hundreds of column that has the same material, when using listagg() from oracle 11.2g, they column width is too wide to fit into the required column.

update eris_data_work e set E.flex37 =
(select
LISTAGG(CM.des, ',') WITHIN GROUP (ORDER BY CM.des) AS casing_material
from CODE_CASING_MATERIAL CM, TBLCASING CA
where CM.code=CA.MATERIAL and CA.well_id=E.owner_oid AND CM.DES IS NOT NULL
GROUP BY CA.well_id)
where E.source='WWIS_ON'

I have even used the regexp_count() to try to eliminate duplicates however I have had no success so far

SQL & PL/SQL :: How To Remove Duplicates From Collection

Mar 24, 2011

remove duplicates from my collection(table type).Or an alternate solution for my issue is get clean data into my collection which i am not able to get to either.

Object creation

create table testingtype_table(ordernumber number,org_id number , company_name varchar2(10))
insert into testingtype_table values (1124,2424,'cbaaa');
insert into testingtype_table values (1124,2424,'cbaaa');

create or replace type testingtype_obj as object (ordernumber number,org_id number , company_name varchar2(10));
create or replace type testingtype_tab as table of testingtype_obj;

Code Block
declare
l_testingtype_tab testingtype_tab := testingtype_tab();
begin
select distinct testingtype_obj(ordernumber
,org_id
,company_name)
bulk collect into l_testingtype_tab
from testingtype_table;
end;

If only i can get a way to bulk collect only distinct values into the table type that will just do great but when i try the above (with distinct highlighted in red) it throws an error

ORA-22950: cannot ORDER objects without MAP or ORDER method

PL/SQL :: Inner Join Resulting In Many To Many Duplicates

Oct 9, 2013

I ran an Inner Join but it returned many, many duplicates. One Answer from a different thread:Because you may be having improper Join condition what has a One to many or a Many to many relationship between the tables. We do not have the data, and hence cannot comment over it. What do I look for to identify an improper join?

Flexible Handling Of Duplicates Using A Trigger

Feb 12, 2007

I'd like to achieve the following (and YES, I do know that this is not multi-user safe, but that's not the point here):

Before inserting a record, the trigger shall check if there's already a duplicate one. Duplicate means in this case when there is an intersection of the time frame, defined by two numeric timestamps. That's also the cause why I cannot use a simple UNIQUE constraint here (in my opinion).

Okay, that already works (see code below). But now I need colliding records to be written to a temporary table so that those records can be returned and presented to the user for selection.

create or replace
TRIGGER TRIGGER1
BEFORE INSERT ON FLIGHT_TABLE
FOR EACH ROW
BEGIN
FOR fs_entry IN (SELECT * FROM FLIGHT_TABLE)
LOOP

[Code] .........

SQL & PL/SQL :: How To Make Return All Records Except Duplicates

Mar 29, 2010

I have a table like this basic example:

ID Product Color Time-In
1 Apple Green May
2 Apple Red April
3 Pear Green May
4 Pear Green April
5 Plum Blue June

In SQL I want to return all 4 fields of the records except those records where Product and Color are identical - in that case it should return the latest (by name of month - preferred) or just the first it finds

So I should get these

1 Apple Green May
2 Apple Red April
3 Pear Green May
5 Plum Blue June

If I do a select distinct then I will only get those fields I test on (product and color), not the rest.

Query Return Results That Contain Duplicates - Only First Or Last Required

May 27, 2008

I have this query that returns results that contain duplicates(somewhat). I only want either the FIRST or LAST (either one is fine). Here is the query:

select unique PLLA.attribute4, PLA.item_description from po_lines_all PLA, po_line_locations_all PLLA
where PLLA.po_line_id = PLA.po_line_id
and PLLA.attribute4 is not null

So my output is something like this:

RCE12 This is an item for AUL1
RCE13 This is an item for PWEILL
RCE14 This is an item for AUL1

I just want either the RCE12 or RCE14 record and not both since they both have the same description.

Remove Duplicates From Slowly Changing Dimension

Jun 6, 2013

I've got a slowly changing dimension table for products with some duplicate attributes -

UNIQUE_ID | DATE_FROM | DATE_TO | PRODUCT_ID | ATTRIBUTE_1 | ATTRIBUTE_2
1 01-JAN-13 02-JAN-13 423 MONKEY 5
2 03-JAN-13 04-JAN-13 423 MONKEY 5
3 05-JAN-13 08-JAN-13 423 MONKEY 4
4 09-JAN-13 10-JAN-13 423 SUPERMONKEY 4
5 01-JAN-13 08-JAN-13 378 BANANA 2
6 09-JAN-13 10-JAN-13 378 BANANA 3

The natural key should be PRODUCT_ID, ATTRIBUTE_1 and ATTRIBUTE_2. The table should therefore be recreated as follows:

UNIQUE_ID | DATE_FROM | DATE_TO | PRODUCT_ID | ATTRIBUTE_1 | ATTRIBUTE_2
1 01-JAN-13 04-JAN-13 423 MONKEY 5
2 05-JAN-13 08-JAN-13 423 MONKEY 4
3 09-JAN-13 10-JAN-13 423 SUPERMONKEY 4
4 01-JAN-13 08-JAN-13 378 BANANA 2
5 09-JAN-13 10-JAN-13 378 BANANA 3

SQL & PL/SQL :: Displaying Records That Are Almost Duplicates With Exception On One Column

Apr 11, 2013

I have a view that is displaying records that are almost duplicates with the exception on one column.

Distric name id status logtime
------- --------- ---- ------ ---------------
ATLANTA John 007 A 4/5/2011 8:20
ATLANTA John 007 B 4/5/2011 8:20
ATLANTA John 007 D 10/5/2012 8:20
JERSY C. Eric 111 C 8/1/2012 4:45
PLANO Jake 522 A 1/2/2012 7:22
DENVER Steve 222 C 11/24/2012 9:00
DENVER Steve 222 D 11/24/2012 9:00

I have a situation where I need to only display one status per name at a specific time.I would like to return the following:

Distric name id status logtime
------- --------- ---- ------ ---------------
ATLANTA John 007 A 4/5/2011 8:20
ATLANTA John 007 D 10/5/2012 8:20
JERSY C. Eric 111 C 8/1/2012 4:45
PLANO Jake 522 A 1/2/2012 7:22
DENVER Steve 222 C 11/24/2012 9:00

So I decided to include a rank for the different statuses to identify the highest rank status and eliminate the lowest rank status records I don't want.

Select distric,name,id,status,
case status
when 'A' then 1
when 'B' then 2
when 'C' then 3
else 4
end statusrank,
logtime
from tst;
[code]...

I would like to return the record with the highest statusrank when they duplicates with the exception of the status column.Is there a built in function I can use for this ? The statusrank can be returned in query. My final return would be:

Distric name id status statusrank logtime
------- --------- ---- ------ ---------- ---------------
ATLANTA John 007 A 1 4/5/2011 8:20
ATLANTA John 007 D 4 10/5/2012 8:20

SQL & PL/SQL :: Copy Into Same Table / Recursive Rename Of Duplicates

May 11, 2011

In MS Windows, if I copy a file and paste it into the same folder, I get a copy with the text 'Copy of' in front of the file name. If I paste it again, I get another copy with a different version number.

E.g.
sqlnet.log
Copy of sqlnet.log
Copy (1) of sqlnet.log
Copy (2) of sqlnet.log

I was wondering if I could copy existing rows into a table and do the same thing?

So, for example if I had this table:

create table tst_srch (srch_is varchar(100), user_name varchar(100), srch_name varchar(100));

insert into tst_srch values (1,'USER1','SRCHA');
insert into tst_srch values (2,'USER1','SRCHB');
insert into tst_srch values (3,'USER1','SRCHC');
insert into tst_srch values (4,'USER1','SRCHD');
insert into tst_srch values (5,'USER2','SRCHC');
insert into tst_srch values (6,'USER2','SRCHD');
insert into tst_srch values (7,'USER2','SRCHD_1');

Could I write a procedure like copy_searches('USER1','USER2') that would copy all USER1's searches to USER2 - including renaming any duplicates.

So it would create these new rows:

8,USER2,SRCHA
9,USER2,SRCHB
10,USER2,SRCHC_1
11,USER2,SRCHD_2

I've looked at various insert statements, merge and match statements and exception handling in procedures .

Reports & Discoverer :: Format Delimited (Tab) Showing Duplicates?

Mar 25, 2011

When I am printing a report in Delimited report format using the default delimiter "Tab", the heading lables is getting printed for all rows( which is fine ) and extra rows of heading labels is getting printed.

Ex:
If I have a heading labels Deptno, Dname and Loc and related data which I print in delimited format, the output will be as follows:

Deptno Dname Loc 10 Accounting NewYork
Deptno Dname Loc 20 Research Dallas
Deptno Dname Loc 30 Sales Chicago
Deptno Dname Loc 40 Operations Boston
Deptno Dname Loc Deptno Dname Loc

Other report formats are working fine.

The same report in different application server environment is working fine.

PL/SQL :: Oracle 12c - Generated By Default As Identity Generates Duplicates?

Jul 24, 2013

I am trying the new Oracle 12c and its feature to create columns with the keyword IDENTITY. I create a table CREATE TABLE xt (a NUMBER GENERATED by default AS IDENTITY PRIMARY KEY, b VARCHAR2(10)); 

And populate it, sometimes specifying the value for a and sometimes relying on the system to generate the value: 

INSERT INTO xt (b) values ('a');INSERT INTO xt (b, a) values ('b', default);INSERT INTO xt (b, a) values ('c', 3);INSERT INTO xt (b) values ('d');INSERT INTO xt (b) values ('e'); 

The problem is that the fourth INSERT fails because the system tries to use the value 3 which is already taken.  The fifth statement gets the value 4.

And the table now contains: A B - -1 a 2 b 3 c 4 e Is there something I am missing? I understood that by specifying BY DEFAULT, I would be allowed to sometimes specify values on my own without them interfering with the generated values. I now that the same thing works correctly in MySQL (where I would get five rows from 1 to 5 with the same INSERT statements) /nikos

Multiple Table Query Returning Duplicates With Wrong Values

Oct 20, 2012

These are the tables I'm working with:

SQL> desc custinfo;
Name Null? Type
----------------------------------------- -------- ----------------------------
CUSTID VARCHAR2(4)
CUSTNAME VARCHAR2(18)
CUSTADR VARCHAR2(12)
CUSTCITY VARCHAR2(10)
CUSTSTATE CHAR(2)
CUSTZIP VARCHAR2(5)
CAPACITY NUMBER(3)
HOUSECODE VARCHAR2(2)
[code]...

I don't understand why the custid is the same for each customer, and why it's selecting every customer and not just those with more than 150 gallons ordered.

For this one use the oil tables that you set up and use a subquery. Select the minimum average fall use from the house table. Then show all customers whose number of gallons delivered times two is greater than the minimum.
