Removing Duplicate Records

Jul 11, 2006

I have a table that holds the following

1 7530568 87143 OESCHD 1/5/2006 6:31:58 AM
1 7530568 87143 OESCHD 1/5/2006 7:02:36 AM

for each 7530568 ordernumber there should only be one OESCHD status.

This is the query I'm using to insert the data sent to me.

INSERT INTO ORDER_EVENTS
SELECT d.division as division,
dt.orderNum as orderNum,
dt.poNum as poNum,
dt.statusCode as statusCode,
dt.statusChangeDate as statusChangeDate
FROM dt_Order_Events dt INNER JOIN
division d ON dt.division = d.divisionShort INNER JOIN
status s ON s.division = d.division AND s.statCode = dt.statusCode
WHERE directive <> 'C' AND
dt.orderNum IN (SELECT orderNum FROM ORDER_HEADER)

This works fine when used with in the hourly transactional update. But When I ran it for the Bulk UpDate (so we'd have historical data) it allowed orders to have statuses to many times.

I am not a SQL guru, I have no idea how to write a sql statement or stored proc that will remove the duplicate records. or how to change what I have to prevent further ones.

Any help would be apreciated.

Removing Duplicate Records With Criteria

Mar 9, 2015

I have regular work that requires me to extract a bunch of customer records from our database, and then remove duplicate address destinations (so we dont mail the same address more than once).

I can currently achieve this using a combination of my poor SQL skills and Excel, but it's really not working out for me, so looking for SQL wizardry necessary to do it just in SQL.

Relevant fields:
Member.AddressBarcode (This is a unique barcode (Text representation of a base-3 number) based on the customer address. So if there's more than one record in the pulled records with the same barcode, we then look at Member.MemberTypeID to determine whether to include this record in the results or discard it as a duplicate. Note that AddressBarcode may be blank if the mailing address couldn't be validated, if it is blank we don't discard it since there is no easy way to detect duplicate addresses without the barcode)

Member.MemberTypeID (This is the type of member account. We have 3 types - Single, Joint Primary, Joint Secondary, represented in this field by the numbers 1/2/3. This is also the order of preference of who to mail. So if there is a Joint Primary and Joint Secondary with the same mailing barcode, we want to discard the Joint Secondary from the results, so that the Joint Primary is the record we include in the results of who to mail.)

Member.ID (Unique numeric ID for each customer. Kind of irrelevant here, but it's a key)

So some pseudo code for what I'm trying to achieve is:

(Member.MemberTypeID = 1)
OR (Member.MemberTypeID = 2 AND Member.AddressBarcode not in results of Member.MemberTypeID = 1)
OR (Member.MemberTypeID = 3 AND Member.AddressBarcode not in results of Member.MemberTypeID = 2 AND Member.AddressBarcode not in results of Member.MemberTypeID = 1)

I suspect it requires some sort of join...

Removing Duplicate Rows

Dec 3, 2005

Hi,

Please give the DML to SELECT the rows avoiding the duplicate rows. Since there is a text column in the table, I couldn't use aggregate function, group by (OR) DISTINCT for processing.

Table :

create table test(col1 int, col2 text)
go
insert into test values(1, 'abc')
go
insert into test values(2, 'abc')
go
insert into test values(2, 'abc')
go
insert into test values(4, 'dbc')
go

Please advise,

Thanks,

Removing Duplicate In Listbox

Apr 23, 2008

Hi There,

I am having a 1st listbox which is populating production lines, 2nd combobox to populate the production units. From here , the user will be able to select multiple production units from the combobox and hence populate the variable in listbox 3.

This is the query that I'm using to query on the variable table:
'SELECT DISTINCT PU_Id,Var_Id,Var_Desc from Variables
where PU_Id IN (@ProductionUnits)'

The problem now is that this would return all the variables for the selected production units and for those variables that have the same name, they would appear in the listbox as duplicates.

I wonder if there's any way to filter off or remove the duplicates in the listbox 3 by using sql query?

Thanks in advance for the help.

SQL: Removing Partial Duplicate Rows

Dec 24, 2007

Hi,
 I have results from a survey in a table, every entry is assigned a unique ID. I want to remove duplicate entries based on the survey data but not on the unique ID (obviously).
So far I have...SELECT DISTINCT RespondantID, Q1, Q2, Q3, Q4, Q5, Q6, Q7, Q8, Q9, Q10, Q11, Q12, Q13
FROM Results
But that gives...

I.e. in the above example, it would seem that 'Martin' submitted his data once and then submitted it again with his name.
 How can I remove the '2 - Anonymous' frrom the data set?
 Thanks!

Removing Duplicate Rows In Grouping

Feb 14, 2012

i've to generate a notepad using this query in vb.net :

strSql = "Select count(*), d.ShareholderId, d.UsufructId, d.BnkAccount, b.SBMCode, " & _
"LTRIM(ISNULL(d.TitleCode + ' ', '')) + LTRIM(ISNULL(d.Forename + ' ', '')) + d.Surname as ShName," & _
"d.BankCode, (select count(*) from (select ShareholderId from dividend " & _
"where CompCode = 'L1' and PaymentMode = 'B' group by ShareholderId, UsufructId, " & _

[Code]....

In the select statement i need to select "d.amount" as well. When i do so, it ask me to insert it in the group by option or in an aggregate function.

Grouping by "d.amount" returns extra field as there can be 2 similar "d.shareholderId" but with different amount.

how to group the "d.amount" without having repetition in the "d.shareholderid" ??

Removing Duplicate Results With One Column Different?

Aug 9, 2012

I am trying to get people from my table that have closed accounts. However, in my table many people have more than one account. They will have multiple closed accounts and some active accounts. I need to get the people with only closed accounts.

Values in the table

Code:
name surname status Closed Number
----------- --------- ----------- ------------- ----------------------------
Jeff Burns closed 2012/01/01 142
Tina Drewmor closed 2008/05/20 546
Jeff Burns active 1900/01/01 354
Kyle Higgin active 1900/01/01 851
Tina Drewmor closed 2009/04/14 154

The query I am using so far is:

Code:
select
d.name,
d.surname,
s.status,
s.closed,
s.number
from
d d inner join s s on d.number = s.number
where
s.status = 'closed'

What I need to see in the results

Code:
name surname status Closed Number
----------- --------- ----------- ------------ -----------------------------

Removing Duplicate Entries In SQL Field

Jan 3, 2007

Hi All,



Below is a snippet of MS SQL inside some VB that retieves
Commodity info such as product names and related information and returns the results in an ASP Page. My problem is that with certain searches, elements returned in the synonym field repeat. For instance, on a correct search I get green, red, blue, and yellow which is correct. On another similar search with different commodity say for material, I get Plastic, Glass,Sand - Plastic, Glass,Sand - Plastic, Glass, Sand. I want to remove the repeating elements returned in this field. IOW, I just need one set of Plastic, Glass and Sand. I hope this makes sense.


Below is the SQL and the results from the returned page.


PS I tried to use distinct but with no luck I want just one of each in the example below.

Thanks in Advance!

Scott

Removing Partially Duplicate Rows For Resultset ? Help Needed.

Feb 2, 2008

Hi, Please help me with an SQL Query that fetches all the records from the three tables but a unique record for each forum and topicid with the maximum lastpostdate. Please provide separate solutions for SqlServer2000/2005. 
I have four tables namely – Forums,Topics,Threads and Messages  in SQL Server2000 (scripts for table creation and insertion of test data given at the end). Now, I have formulated a query as below :- 
SELECT Forums.forumid AS ForumID,Topics.topicid AS TopicID,Topics.name AS TopicName,LastPosts.date as LastPostDate,LastPosts.author AS Author,
(select count(threadid) from Threads where Threads.topicid=Topics.topicid) as NoOfThreads
FROM Forums JOIN Topics ON Forums.forumid=Topics.forumid
LEFT OUTER JOIN
(
                 SELECT Topics.forumid,Threads.topicid,Messages.date,Messages.author FROM Topics
             INNER JOIN Threads ON Topics.topicid = Threads.topicid
                 INNER JOIN Messages ON Threads.threadid=Messages.threadid
             WHERE Messages.date=(SELECT MAX(date) FROM Messages WHERE Messages.threadid = Threads.threadid)
) as LastPosts
ON LastPosts.forumid = Topics.forumid AND LastPosts.topicid = Topics.topicid 
Whose result set is as below:-

Removing Duplicate Delimited Values From A Single Column?

Jun 18, 2014

I have a stored procedure that returns a single row based on a parameter of employee ID. This particular procedure uses a CTE to traverse our org structure. One of the columns is returning a delimited string of Windows login values and due to the business rules, it can contain duplicate values. I need to have that column contain only unique values - no dupes.

For example, this one column could contain something like this:

domainuser1;domainuser2;domainuser2;domainuser 3;

The need is to convert to this:

domainuser1;domainuser2;domainuser3;

I know that's a tall order.

Removing Duplicate Rows With CTE And Partition - Need Most Recent Entry

Sep 28, 2007

I have tested the code below to remove duplicate table entries based on the field IntOOS. This code works; however, I want to ensure I am removing the oldest entries and keeping the most recent entry. The field to key on this would be something like Max(ID). What would be the best way to ensure I keep the most recent table entry?

Transact SQL :: Removing Duplicate Values In ID Column Of Table

Oct 14, 2015

I need write a query for removing duplicates, for Example in my table I have columns

A_ID name id
1 sam 10
2 sam 10
3  sam 10
4 sam 10
5  ccc 15
6 ccc 15
7  ccc 15

So now I have duplicates values in id column so now I need to take only one value of each and delete the remaining. I need to take first id value 10,15,20 so only 3 rows should be there in my table.

Comparing Similar Tables - Removing Duplicate Or Repeated Data

Sep 30, 2007

It seems that there should be a solution for my situation, but for the life of me I can't seem to figure it out.

I need to compare two "like" tables, containing similar data. Tbl 1 is "BOOKED" (which is a snapshot of inventory) and tbl 2 is "CURRENT" (the live - working inventory table). If I write my query as follows the the subsequent result is "duplicate" data.




Code Block
SELECT booked.item, booked.bin, booked.quantity, current.bin, current.quantity
FROM BOOKED
LEFT JOIN
CURRENT
ON booked.item = current.item







No matter what type of join I use, there is duplicate data displayed for each table. For example, if there are more bins in the BOOKED table that contain a certain product then the CURRENT table will repeat data and vica versa.

As follows:







Item
Bin
Quantity
Bin
Quantity

12345
A01
500
A01
7680

12345
B01
6
A01
7680

12345
C01
20
A01
7680

54321
G10
1032
E15
1163

54321
G10
1032
F20
523

54321
G10
1032
H30
750

98765
Z20
7000
Z20
8500

98765
Y15
2500
Y15
3000

98765
X10
1200
Y15
3000

What I would like to do is display Bin and Quantity only once and the repeating values as NULL or [BLANK]. Or, to display all of the bins from both tables and only the quantities from each table in relation to the bin found in that table, returning a "0" if no quantity exists.

This is what I'm after:







Item
Bin
Quantity
Bin
Quantity

12345
A01
500
A01
7680

12345
B01
6
B01
0

12345
C01
20
C01
0

54321
G10
1032
E15
1163

54321
F20
0
F20
523

54321
H30
0
H30
750

98765
Z20
7000
Z20
8500

98765
Y15
2500
Y15
3000

98765
X10
1200
X10
0



Is this possible? If so, how?

I also might add that it is ok for each table to contain multiple entries for any given item. This is basically being requested as an inventory variance report - inventory before physical count and immediatly after physical count - and will only be run once a year.

-----------------------------------------------
Just thinking out loud here:
What if I created three subqueries, the first containing only BOOKED information, the second containing only CURRENT information and the third being a UNION of both tables? Something like this:




Code Block
SELECT q3.bin, q1.item, ISNULL(q1.quantity, 0) as QTY_BEFORE, ISNULL(q2.quantity, 0) as QTY_AFTER

FROM

(select item, bin, quantity
from BOOKED)q1
Left Join

(select item, bin, quantity
from CURRENT)q2
on q1.item = q2.item
Left Join

(select bin, item
from BOOKED
UNION
CURRENT)q3
on q1.item = q3.item

Order By q1.item





I don't know if I wrote the UNION statement correctly, but I will have to try this when I get back to work...


Any suggestions?

Removing Duplicated Records

Dec 2, 2005

Hi,

Need to remove the duplicated rows from a table which has text/ntext/image type columns. The table does not have any PK/Unique column. (I accept its a bad data model). But currently changing the data model is not possible. Hence doing changes in application.

I couldn't do 'SELECT DISTINCT * from table', since the table has text columns. Though there is no PK constraint, If I know that col1 and col2 are join PKs in the table, Is that possible to select the distinct rows from such a table.

Please advise,

Thanks,
MiraJ

Removing Old Records While Retaining Recent Ones

Apr 12, 2006

Hey guys, I have a table full of data that has duplicate records except for two date columns (date1 and date2). What I would like to do is remove the duplicates while retaining the most recent record, how can I do this?

So record 1 looks like this:


Code:

John | Smith | 08/08/2000 | 10/10/2000



Record 2 looks like this:


Code:

John | Smith | 08/10/2005 | 10/10/2005



I'd like to remove the first instance and keep the second (most recent one).

Ideas?

Thanks!

Duplicate Records

Jun 12, 2002

Yes, I know this subject has been exhausted, but I need help in locating the discussion which took place a few months ago.
Sharon relayed to the group a piece of software (expensive) which would help in my particular situation. I grabbed a demo and have gotten the approval for purchase. Unfortunately, I don't have the thread with me at work.

The problem:

Number Fname Lname Age ID
123 John Franklin 43 1
123 Jane Franklin 40 2
123 Jeff Franklin 12 3
124 Jean Simmons 39 4
125 Gary Bender 37 5
126 Fred Johnson 29 6
126 Fred Johnson 39 7
127 Gene Simmons 47 8

The idea would be to get only unique records from the Number column. I don't care about which information I grab from the other columns, but I must have those fields included.
If my resultant result set looked as follows, that would be fine. Or any other way, as long as all of the fields had information and there were only unique values in the Number field.

Number Fname Lname Age ID
123 Jeff Franklin 12 3
124 Jean Simmons 39 4
125 Gary Bender 37 5
126 Fred Johnson 39 7
127 Gene Simmons 47 8

If anyone remembers this discussion, mainly the date, I would really appreciate it.

Thanks

Duplicate Records

Feb 17, 2008

I have two tables, one contains all work orders, the second contains records on work orders that are linked to customoer orders. I'm trying to create a query that will return specific fields from the table that contains orders in the linked order table, and only the work orders in the all order table that (work_order) do not exist in the linked order table (demand_supply_link). I have tried several queries and cannot get the results I desire. Here is the query I am currently trying.

SELECT DISTINCT WORK_ORDER.DESIRED_WANT_DATE as 'Want Date', DEMAND_SUPPLY_LINK.SUPPLY_BASE_ID as 'WO Id',
WORK_ORDER.DESIRED_QTY as 'End Qty', DEMAND_SUPPLY_LINK.SUPPLY_PART_ID as 'Part Id', CUST_ORDER_LINE.CUSTOMER_PART_ID as 'Cust Part',
OPERATION.RESOURCE_ID as Resource, PART.DESCRIPTION as Description, CUSTOMER.NAME as Name
FROM ((((DEMAND_SUPPLY_LINK INNER JOIN CUST_ORDER_LINE ON DEMAND_SUPPLY_LINK.DEMAND_BASE_ID = CUST_ORDER_LINE.CUST_ORDER_ID)
INNER JOIN WORK_ORDER ON DEMAND_SUPPLY_LINK.SUPPLY_BASE_ID = WORK_ORDER.BASE_ID)
INNER JOIN OPERATION ON WORK_ORDER.BASE_ID = OPERATION.WORKORDER_BASE_ID) INNER JOIN PART ON WORK_ORDER.PART_ID = PART.ID)
INNER JOIN (CUSTOMER INNER JOIN CUSTOMER_ORDER ON CUSTOMER.ID = CUSTOMER_ORDER.CUSTOMER_ID) ON CUST_ORDER_LINE.CUST_ORDER_ID = CUSTOMER_ORDER.ID
WHERE WORK_ORDER.DESIRED_WANT_DATE Is Not Null AND OPERATION.RESOURCE_ID in ('ASSY','FAB 1','PLAY TRK')
AND WORK_ORDER.STATUS='R'

UNION
SELECT distinct work_order.desired_want_date as 'Want Date', work_order.BASE_id as 'WO Id',
work_order.desired_qty as 'End Qty', work_order.part_id as 'Part Id', operation.resource_id as Resource,
part.description as Description
FROM WORK_ORDER INNER JOIN PART ON PART_ID=WORK_ORDER.PART_ID INNER JOIN OPERATION ON WORK_ORDER.BASE_ID=OPERATION.WORKORDER_BASE_ID
WHERE WORK_ORDER.DESIRED_WANT_DATE IS NOT NULL AND OPERATION.RESOURCE_ID IN ('ASSY','FAB 1', 'PLAY TRK')
AND WORK_ORDER.STATUS='R'

This is the error I receive:
Server: Msg 205, Level 16, State 1, Line 1
All queries in an SQL statement containing a UNION operator must have an equal number of expressions in their target lists.

The all orders table (work_order) will not have the other fields to link to as there is no customer order linked to them.

Can anyone help. Thanks!
