Query to find duplicate referance numbers

Dear,
We have somehow managed to create the same sales order twice or more. In the field "Customer Ref. No." we always type in BP's ref. no. So what I need is a query which will show me all open sales orders which have more than one identical "Customer Ref. No." (ORDR.NumAtCard)
So what I got so far is:
SELECT T0.[DocNum], T0.[NumAtCard] FROM ORDR T0 WHERE T0.[DocStatus] <> 'C' AND ????
Hope anyone can help. Thanks.

Hi Kjetil Sandvik,
If you want to block Sales Order with duplicare Customer Ref. No then
Try this SP.....
if (@object_type = '17')
and (@transaction_type= 'A' or @transaction_type= 'U')
begin
declare @Refno as varchar(100), @Cust as varchar(100)
if @object_type = '17'
begin
select @Refno = NumAtCard,
@Cust=CardCode
from ordr
where DocEntry =@list_of_cols_val_tab_del
if 1 != (select count(DocEntry) from ordr with(nolock) where NumAtCard = @Refno and CardCode=@Cust)
begin
select @error = 1
select @error_message = 'Customer Ref. No Should Not Be Repeated. ! '
end
end
end
Thanks,

Query to find duplicates, update appropriately, delete one of those duplicate

I have duplicate rows in below given table and need to cleanse it by observing another duplicate record.
I'd like to know various ways to achieve it. (I'm confused I should use UPDATE.. (CASE WHEN.. THEN).. or MERGE or something else)
Please find below DDL/DML.
create table MyTable
PKey int identity(1,1),
CustID int,
FirstName varchar(10),
LastName varchar(10),

Hi Vaibhav,
Manu's has copied as a part of the below code.
create table MyTable
PKey int identity(1,1),
CustID int,
FirstName varchar(10),
LastName varchar(10),
Main varchar(10),
Department varchar(10)
Insert into MyTable--(CustID,FirstName,LastName,Main,Department)
select 101, 'aaa','bbb','VM','Marketing' union

select 102, '', 'yyy', 'Main', 'Marketing' union
select 102, 'xxx','','','' union
select 103, 'ppp', 'qqq', '', 'HR' union
select 103, '', '', 'MF', '' union
select 104, 'mmm', 'nnn', 'f', 'dept'
SELECT * FROM MyTable;

MERGE mytable AS Tar

UPDATE SET Tar.CustID = Src.CustID, Tar.FirstName = Src.FirstName,Tar.LastName = Src.LastName, Tar.Main = Src.Main,Tar.Department = Src.Department
WHEN NOT MATCHED BY SOURCE THEN
DELETE
SELECT * FROM MyTable
DROP TABLE MyTable;
If you do care about the Identity Pkey, as per the expected output, my understanding on your logic is like below.
;WITH cte AS
SELECT PKey, CustID,V1,V2,V3,V4,ROW_NUMBER() OVER(PARTITION BY CustID ORDER BY v1+v2+v3+v4 DESC) AS RN
FROM MyTable
CROSS APPLY(SELECT CASE WHEN FirstName ='' THEN 0 ELSE 1 END AS v1) AS cat1
CROSS APPLY(SELECT CASE WHEN LastName ='' THEN 0 ELSE 1 END AS v2) AS cat2
CROSS APPLY(SELECT CASE WHEN Main ='' THEN 0 ELSE 1 END AS v3) AS cat3
CROSS APPLY(SELECT CASE WHEN Department ='' THEN 0 ELSE 1 END AS v4) AS cat4
,cte2 AS
SELECT DISTINCT
CustID,
MAX(FirstName) AS FirstName,
MAX(LastName)AS LastName,
MAX(Main) AS Main,
MAX(Department) AS Department
FROM mytable
GROUP BY CustID
,cte3 AS
SELECT c2.CustID,c2.FirstName,c2.LastName,c2.Main,c2.Department,c.PKey FROM cte2 c2 JOIN cte c ON c.CustID = c2.CustID WHERE NOT EXISTS(SELECT 1 FROM cte WHERE RN<c.RN)
MERGE mytable AS Tar
USING cte3 AS Src
ON Tar.PKey = Src.PKey
WHEN MATCHED THEN
UPDATE SET Tar.CustID = Src.CustID, Tar.FirstName = Src.FirstName,Tar.LastName = Src.LastName, Tar.Main = Src.Main,Tar.Department = Src.Department
WHEN NOT MATCHED BY SOURCE THEN
DELETE

Query to find duplicate records (Urgent!!!!)

Hi,
I have a to load data from a staging table to base table but I dont want to load data already present in the base table. Criteria to identify the duplicate data is thorugh a field say v_id and status_flag. If these two are the same in both staging and base table then that record must be rejected as a duplicate record.
Kindly help me with the SQL which i need to use in a Procedure.
Thanks

Finding duplicate values in a column with different values in a different c

I'm finding duplicate values in a column of my table:
select ba.CLAIM_NUMBER from bsi_auto_vw ba
group by ba.CLAIM_NUMBER
having count(*) > 1;
How can I modify this query to find duplicate values in that column where I DON'T have duplicate values in a different specific column in that table (the column CLMT_NO in my case can't have duplicates.)?

Well, you can use analytics assuming you don't mind full scanning the table.....
select
count(owner) over (partition by object_type),
count(object_type) over (partition by owner)
from all_objects;You just need to intelligently (i didn't here) find your "window" (partition clause) to sort the data over, then make use of that (the analytics would be in a nested SQL and you'd then evaluate it in outside).
Should be applicable if i understand what you're after.
If you post some sample data we can mock up a SQL statement for you (if what i tried to convey wasn't understandable).

How do I find duplicate words in a Numbers spreadsheet?

Hello, I've created my first document on Numbers and am trying to figure out how to find duplicate words. Ideally, a list of words that repeat in the document and how many times. Is this possible? Thank you in advance for the advice

It's easy enough to find and count duplicate entries, especially if they are all in a single column, but if you want to count individual words within multi word entries, the problem is more complicated.
Here's an example for the 'simple' case, using a familiar 155 word passage from English literature.
The words in the passage are separated into a single line for each word, and stripped of all punctuation. This may be done in Pages, or in Text edit, or in pretty much any word processing software or text editor. Paste the passage into a WP or text document, then use the application's Find/Replace feature to replace all of the spaces with returns. I would also do a second pass replacing all double returns with single returns, then repeat that until Find/Replace reported replacing zero occurrences.
Punctuation was stripped using Find/Replace
The prepared list was pasted into column A of a Numbers table.
Formulas:
B2: =COUNTIF($A$1:A2,A2)
C2: =IF(AND(B>1,B=COUNTIF($A,A2)),ROW()-1,999999)
Fill both down their respective columns to the end of the table.
The small table is inserted as a Basic table using the Tables button. It contains a Header row, but no Header columns.
Formula:
A2: =IFERROR(OFFSET(Table 1 :: $A$1,SMALL(Table 1 :: $C,ROW()-1),COLUMN()-1),"")
Fill right into B2, then fill both down to the end of the table.
Descriptions of the functions used, along with their syntax and at least one example of their use in a table are available in the Numbers '09 User Guide, which may be downloaded via the Help menu in Numbers.

Barry

Find Duplicate Query MySQL Syntax

There is a "find duplicates" query in SQL that is very useful
but I'm not sure what the syntax is for MySQL. It probably has
something to do with select distinct, group by but I'm not used to
to using these.
This is one that finds all duplicates of [FULLNAME]
SELECT CONTACTS.*
WHERE (((CONTACTS.FULLNAME) In (SELECT [FULLNAME] FROM
[CONTACTS] As Tmp GROUP BY [FULLNAME]
HAVING Count(*)>1 )))
ORDER BY CONTACTS.FULLNAME, CONTACTS.COMPANY
Does anyone know?

SELECT COUNT(*) AS repetitions, FULLNAME, COMPANY
FROM CONTACTS
GROUP BY FULLNAME, COMPANY
HAVING repetitions > 1
It's not something I have used myself, but I got it from
MySQL Cookbook
by Paul DuBois, published by O'Reilly. I have the first
edition, which
covers MySQL 4.0. I think the second edition covers MySQL
5.0.
If you're using MySQL on a regular basis, you or your
employer should
buy it immediately. It will solve most of your problems and
repay its
cost many times over.

Help with Finding Duplicate records Query

HI,
I am trying to write a query that will find duplicate records/cases.
This query will be used in a report.
So, here are the requirements:
I need to find duplicate cases/records based on the following fields:
DOB, DOCKET, SENT_DATEI was able to do that with the following query. The query below is able to give me all duplicate records based on the Criteria above
SELECT      DEF.BIRTH_DATE DOB,
           S.DOCKET DOCKET,
           S.SENT_VIO_DATE SENT_DATE, COUNT(*)
FROM SENTENCES S,
            DEFENDANTS DEF
WHERE      S.DEF_ID = DEF.DEF_ID
AND       S.CASE_TYPE_CODE = 10
GROUP BY DEF.BIRTH_DATE, S.DOCKET, S.SENT_VIO_DATE
HAVING COUNT(*) > 1;
//I AM GOING TO CALL THIS QUERY 'X'Now, the information to be displayed on the report: defendants Name, DOB, District, Docket, Def Num, Sent Date, and PACTS Num if possible.
The problem that I need help on is how to combine those queries together (what I mean is a sub query). the 'X' query returns multiple values. please have a look at the comments on the query below to see what I'm trying to achieve.
here is the main query:
SELECT      INITCAP(DEF.LAST_NAME) || ' ' || INITCAP(DEF.FIRST_NAME) || ' ' || INITCAP(DEF.MIDDLE_NAME) DEFENDANT_NAME,
        DEF.BIRTH_DATE DOB,
        TRIM(DIST.DISTRICT_NAME) DISTRICT_NAME,
        S.DOCKET DOCKET,
        S.DEF_NUM DEF_NUM,
        S.SENT_VIO_DATE SENT_DATE,
        DEF.PACTS_ID PACTS_NUM
FROM      USSC_CASES.DEFENDANTS DEF,
        USSC_CASES.SENTENCES S,
        LOOKUP.DISTRICTS DIST
WHERE      DEF.DEF_ID = S.DEF_ID
AND      S.DIST_ID = DIST.USSC_DISTRICT_ID
AND     S.CASE_TYPE_CODE = 10
AND     S.USSC_ID IS NOT NULL
AND // what i'm trying to do is: DOB, DOCKET, SENT_DATE IN ('X' QUERY), is this possible ??
ORDER BY DEFENDANT_NAME; thanks in advance.
I am using Oracle 11g, and sql developer.
if my approach doesn't work, is there a better approach ?
Edited by: Rooney on Jul 11, 2012 3:50 PM

If I got it right, you want to join table USSC_CASES.DEFENDANTS to duplicate rows in USSC_CASES. If so:
SELECT INITCAP(DEF.LAST_NAME) || ' ' || INITCAP(DEF.FIRST_NAME) || ' ' || INITCAP(DEF.MIDDLE_NAME) DEFENDANT_NAME,
        DEF.BIRTH_DATE DOB,
        TRIM(DIST.DISTRICT_NAME) DISTRICT_NAME,

Script to find duplicate index and how can we tell if an index is REALLY a duplicate?

Does any one have script to find duplicate index? and how can we tell if an index is REALLY a duplicate?

The first query finds exact matches. The indexes must have
the same key columns in the same order, and the same included columns but in any order.
These indexes are sure targets for elimination. The only caution would be to check for index hints.
-- exact duplicates
with indexcols as
select object_id as id, index_id as indid, name,
(select case keyno when 0 then NULL else colid end as [data()]
from sys.sysindexkeys as k
where k.id = i.object_id
and k.indid = i.index_id
order by keyno, colid
for xml path('')) as cols,
(select case keyno when 0 then colid else NULL end as [data()]
from sys.sysindexkeys as k
where k.id = i.object_id
and k.indid = i.index_id
order by colid
for xml path('')) as inc
from sys.indexes as i
select
object_schema_name(c1.id) + '.' + object_name(c1.id) as 'table',
c1.name as 'index',
c2.name as 'exactduplicate'
from indexcols as c1
join indexcols as c2
on c1.id = c2.id
and c1.indid < c2.indid
and c1.cols = c2.cols
and c1.inc = c2.inc;
The second variation of this query finds partial, or duplicate, indexes
that share leading key columns, e.g. Ix1(col1, col2, col3) and Ix2(col1, col2)
would be considered duplicate indexes. This query only examines key columns and does not consider included columns.
These types of indexes are probable dead indexes walking.
-- Overlapping indxes
with indexcols as
select object_id as id, index_id as indid, name,
(select case keyno when 0 then NULL else colid end as [data()]
from sys.sysindexkeys as k
where k.id = i.object_id
and k.indid = i.index_id
order by keyno, colid
for xml path('')) as cols
from sys.indexes as i
select
object_schema_name(c1.id) + '.' + object_name(c1.id) as 'table',
c1.name as 'index',
c2.name as 'partialduplicate'
from indexcols as c1
join indexcols as c2
on c1.id = c2.id
and c1.indid < c2.indid
and (c1.cols like c2.cols + '%'
or c2.cols like c1.cols + '%') ;
Be careful when dropping a partial duplicate index if the two indexes differ greatly in width.
For example, if Ix1 is a very wide index with 12 columns, and Ix2 is a narrow two-column index
that shares the first two columns, you may want to leave Ix2 as a faster, tighter, narrower index.

Finding missed sequence numbers and rows from a fact table

Finding missed sequence numbers and rows from a fact table
Hi
I am working on an OLAP date cube with the following schema:
As you can see there is a fact transaction with two dimensions called cardNumber and Sequence. Card dimension contains about three million card numbers.
Sequence dimension contains a sequence number from 0 to 255. Fact transaction contains about 400 million transactions of those cards.
Each transaction has a sequence number in 0 to 255 ranges. If sequence number of transactions of a card reaches to 255 the next transaction would get 0 as a sequence number.
For example if a card has 1000 transactions then sequence numbers are as follows;
Transaction 1 to transaction 256 with sequences from 0 to 255
Transaction 257 to transaction 512 with sequences from 0 to 255
Transaction 513 to transaction 768 with sequences from 0 to 255
Transaction 769 to transaction 1000 with sequences from 0 to 231
The problem is that:
Sometimes there are several missed transactions. For example instead of sequence from 0 to 255, sequences are from 0 to 150 and then from 160 to 255. Here 10 transactions have been missed.
How can I find all missed transactions of all cards with a MDX QUERY?
I really appreciate for helps

Thank you Liao
I need to find missed numbers, In this scenario I want the query to tell the missed numbers are: 151,152,153,154,155,156,157,158,159
Relative transactions are also missed, so I think it is impossible to get them by your MDX query
Suppose this:
date
time
sequence
20140701
23:22:00
149
20140701
23:44:00
150
20140702
8:30:00
160
20140702
9:30:00
161
20140702
11:30:00
162
20140702
11:45:00
163
As you can see the sequence number of the last transaction at the 20140701 is 150
We expecting that the first transaction of the next day should be 151 but it is 160. Those 10 transactions are totally missed and we just need to
find missed sequence numbers

How to remove duplicate phone numbers under iMessage settings?

I've been using iMessage for a while now and a lot of my friends have brought to my attention that every iMessage I sent showed it came from my email rather than my phone number. So I signed out of iMessage and tried logging back in using my phone number and it would not work, saying the activation did not go through. So I tried again and again throughout the day and it finally worked eventually. The problem is I get a duplicate (lots of it) of my phone numbers, I'm guessing from my countless attempts at signing in. How do I go about removing all the duplicates that are grayed out? Also why do the last three have tick marks next to them? How do I make it so that only one of them is tickmarked and delete the rest of the duplicates. I've provided screenshots below.
Also, "waiting for activation..." has been shown under the settings for almost the whole day. How long does this take?

I've tried signing out and back in again. It doesn't do anything. I still get the unnecesarily long list of duplicate phone numbers and have 2 or 3 of them randomly tick marked. I've tried this multiple times, it doesn't get rid of them at all. As far as I'm concerned, my friends do receive my iMessage from my number rather than my email. I just find it a nuisance to have such a long list of my phone number 25 times over. I don't think it affects anything though, but any way to get rid of them would be great.
Also, it's been 3 days and it still says "waiting for activation" on my iMessage and Facetime settings. How long does this take? As far as I know, my friends have told me iMessaging with me is flawless but I'm confused as to why it's still trying to activate.
