Delete Duplicates

Mar 20, 2007

Some guy posted that the syntax: delete top 1 from some_table works for deleting duplicates. I am pretty sure that doesnt work but I wanted to check just in case it did because it would be a really easy to delete duplicates.

Aug 8, 2007

Hi everybody I need help on finding duplicates and deleting the duplicate record depending on name and fname , deleting the duplicates and leaving only the first one.

my PERSON table is this below:

ID name fname ownerid id2

1 a b
2 c c
3 e f
4 a b 1 10
5 c c 2 11

I have this query below that returns records 1 and 4 and 2 and 5 since they have the same name and fname

select * from ( Select name ,fname, count(1) as cnt from PERSON group by
name,Fname ) where cnt > 1


ID name fname ownerid id2

Howto: Delete Every Second Record If Duplicates

Jul 19, 2007

Hi.I have a "union" table which results of a union of two tables.Occasionally I could have duplicates, when the same PIN has been addedto both tables, albeit at different Datees/Times, such as:PINNameAdded Date100411A7/11/2007 10:12:58 AM100411A7/17/2007 10:54:23 AM100413B7/11/2007 10:13:28 AM100413B7/17/2007 10:54:39 AM104229C7/6/2007 2:34:13 PM104231D7/6/2007 2:34:25 PM104869E6/10/2007 11:59:12 AM104869E6/22/2007 2:40:18 PMThe question is - how can I delete by queries the first occurence(time-wise) of these duplicates - i.e. I would want to delete thefirst occurence of 100411 (A), the first occurence of 100413 (B), andthe first occurence of 104869 (E) in the example above - records C andD show only once, so they are fine.Is there a MsAccess solution ? Is there a SQL-server solution ?Thank you very much !Alex

Optimizing A Query To Delete Duplicates

Jul 20, 2005

I have a DELETE statement that deletes duplicate data from a table. Ittakes a long time to execute, so I thought I'd seek advice here. Thestructure of the table is little funny. The following is NOT the table,but the representation of the data in the table:+-----------+| a | b |+-----+-----+| 123 | 234 || 345 | 456 || 123 | 123 |+-----+-----+As you can see, the data is tabular. This is how it is stored in the table:+-----+-----------+------------+| Row | FieldName | FieldValue |+-----+-----------+------------+| 1 | a | 123 || 1 | b | 234 || 2 | a | 345 || 2 | b | 456 || 3 | a | 123 || 3 | b | 234 |+-----+-----------+------------+What I need is to delete all records having the same "Row" when there existsthe same set of records with a different (smaller, to be precise) "Row".Using the example above, what I need to get is:+-----+-----------+------------+| Row | FieldName | FieldValue |+-----+-----------+------------+| 1 | a | 123 || 1 | b | 234 || 2 | a | 345 || 2 | b | 456 |+-----+-----------+------------+A slow way of doing this seem to be:DELETE FROM XWHERE Row IN(SELECT DISTINCT Row FROM X x1WHERE EXISTS(SELECT * FROM X x2WHERE x2.Row < x1.RowAND NOT EXISTS(SELECT * FROM X x3WHERE x3.Row = x2.RowAND x3.FieldName = x2.FieldNameAND x3.FieldValue <> x1.FieldValue)))Can this be done faster, better, and cheaper?

T-SQL (SS2K8) :: Delete Duplicates From Table Based On Two Columns?

May 20, 2015

Assuming I have a table similar to the following:

Auto_ID Account_ID Account_Name Account_Contact Priority
1 3453463 Tire Co Doug 1
2 4363763 Computers Inc Sam 1
3 7857433 Safety First Heather 1
4 2326743 Car Dept Clark 1
5 2342567 Sales Force Amy 1
6 4363763 Computers Inc Jamie 2
7 2326743 Car Dept Jenn 2

I'm trying to delete all duplicate Account_IDs, but only for the highest priority (in this case it would be the lowest number).

I know the following would delete duplicate Account_IDs:

DELETE FROM staging_account
WHERE auto_id NOT IN
(SELECT MAX(auto_id)
FROM staging_account
GROUP BY account_id)

The problem is this doesn't take into account the priority; in the above example I would want to keep auto_ids 2 and 4 because they have a higher priority (1) than auto_ids 6 and 7 (priority 2).

How can I take priority into account and still remove duplicates in this scenario?

T-SQL (SS2K8) :: Rank Duplicates But Only Rows Involved In Duplicates?

Oct 22, 2014

I have a table with 22 million Business records. I can see that there are duplicates when I group by BusinessName and Address and Phone. I'd like to place only the duplicates into a table, with a ranking, oldest business key gets a ranking of 1.

As a bonus I'd like each group to have a distinct group name (although not necessary, just want to know how to do this)

Later after I run more verifications to make sure these are not referenced elsewhere I'll delete everything with a matchRank > 1 out of the main Business table.

DROP TABLE [dbo].[TestBusiness];
GO
CREATE TABLE [dbo].[TestBusiness](
[Business_pk] INT IDENTITY(1,1) NOT NULL,
[BusinessName] VARCHAR (200) NOT NULL,
[Address] VARCHAR(MAX) NOT NULL,

[code]....

Master Data Services :: Hard Delete All Soft Delete Records (members) In Database

May 19, 2012

I am using Master Data Service for couple of months now. I can load, update, merge and soft delete data in MDS. Occasionally we even have to hard delete data from MDS. If we keep on soft deleting records in a MDS table eventually there will be huge number of soft deleted records. Is there an easy way to hard delete all the soft deleted records from all MDS tables in a specific Model.

Copy And Delete Table With Foreign Key References(...,...) On Delete Cascade?

Oct 23, 2004

Hello:
Need some serious help with this one...

Background:
Am working on completing an ORM that can not only handles CRUD actions -- but that can also updates the structure of a table transparently when the class defs change. Reason for this is that I can't get the SQL scripts that would work for updating a software on SqlServer to be portable to other DBMS systems. Doing it by code, rather than SQL batch has a chance of making cross-platform, updateable, software...

Anyway, because it needs to be cross-DBMS capable, the constraints are that the system used must work for the lowest common denominator....ie, a 'recipe' of steps that will work on all DBMS's.

The Problem:
There might be simpler ways to do this with SqlServer (all ears :-) - just in case I can't make it cross platform right now) but, with simplistic DBMS's (SqlLite, etc) there is no way to ALTER table once formed: one has to COPY the Table to a new TMP name, adding a Column in the process, then delete the original, then rename the TMP to the original name.

This appears possible in SqlServer too --...as long as there are no CASCADE operations.
Truncate table doesn't seem to be the solution, nor drop, as they all seem to trigger a Cascade delete in the Foreign Table.

So -- please correct me if I am wrong here -- it appears that the operations would be
along the lines of:
a) Remove the Foreign Key references
b) Copy the table structure, and make a new temp table, adding the column
c) Copy the data over
d) Add the FK relations, that used to be in the first table, to the new table
e) Delete the original
f) Done?

The questions are:
a) How does one alter a table to REMOVE the Foreign Key References part, if it has no 'name'.
b) Anyone know of a good clean way to get, and save these constraints to reapply them to the new table. Hopefully with some cross platform ADO.NET solution? GetSchema etc appears to me to be very dbms dependant?
c) ANY and all tips on things I might run into later that I have not mentioned, are also greatly appreciated.

Thanks!
Sky

SQL - Cascading Delete, Or Delete Trigger, Maintaining Referential Integrity - PLEASE HELP ME!!!

Nov 13, 2006

I am having great difficulty with cascading deletes, delete triggers and referential integrity.

The database is in First Normal Form.

I have some tables that are child tables with two foreign keyes to two different parent tables, for example:

Table A
/
Table B Table C
/
Table D

So if I try to turn on cascading deletes for A/B, A/C, B/D and C/D relationships, I get an error that I cannot have cascading delete because it would create multiple cascade paths. I do understand why this is happening. If I delete a row in Table A, I want it to delete child rows in Table B and table C, and then child rows in table D as well. But if I delete a row in Table C, I want it to delete child rows in Table D, and if I delete a row in Table B, I want it to also delete child rows in Table D.

SQL sees this as cyclical, because if I delete a row in table A, both table B and table C would try to delete their child rows in table D.

Ok, so I thought, no biggie, I'll just use delete triggers. So I created delete triggers that will delete child rows in table B and table C when deleting a row in table A. Then I created triggers in both Table B and Table C that would delete child rows in Table D.

When I try to delete a row in table A, B or C, I get the error "Delete Statement Conflicted with COLUMN REFERENCE". This does not make sense to me, can anyone explain? I have a trigger in place that should be deleting the child rows before it attempts to delete the parent row...isn't that the whole point of delete triggers?????

This is an example of my delete trigger:

CREATE TRIGGER [DeleteA] ON A
FOR DELETE
AS
Delete from B where MeetingID = ID;
Delete from C where MeetingID = ID;

And then Table B and C both have delete triggers to delete child rows in table D. But it never gets to that point, none of the triggers execute because the above error happens first.

So if I then go into the relationships, and deselect the option for "Enforce relationship for INSERTs and UPDATEs" these triggers all work just fine. Only problem is that now I have no referential integrity and I can simply create unrestrained child rows that do not reference actual foreign keys in the parent table.

So the question is, how do I maintain referential integrity and also have the database delete child rows, keeping in mind that the cascading deletes will not work because of the multiple cascade paths (which are certainly required).

Hope this makes sense...
Thanks,
Josh

Delete Syntax To Delete A Record From One Table If A Matching Value Isn't Found In Another

Nov 17, 2006

I'm trying to clean up a database design and I'm in a situation to where two tables need a FK but since it didn't exist before there are orphaned records.

Tables are:

Brokers and it's PK is BID

The 2nd table is Broker_Rates which also has a BID table.

I'm trying to figure out a t-sql statement that will parse through all the recrods in the Broker_Rates table and delete the record if there isn't a match for the BID record in the brokers table.

I know this isn't correct syntax but should hopefully clear up what I'm asking

DELETE FROM Broker_Rates

WHERE (Broker_Rates.BID <> Broker.BID)

Thanks

How To Run Delete Query / Delete Several Rows Just By One Click ?

Feb 16, 2008

I'm using SqlDataSource and an Access database. Let's say I got two tables:user: userID, usernamemessage: userID, messagetextLet's say a user can register on my website, and leave several messages there. I have an admin page where I can select a user and delete all of his messages just by clicking one button.What would be the best (and easiest) way to make this?Here's my suggestion:I have made a "delete query" (with userID as parameter) in MS Access. It deletes all messages of a user when I type in the userID and click ok.Would it be possible to do this on my ASP.net page? If yes, what would the script look like?(yes, it is a newbie question)

Allow Single Row Delete From A Table But Not Bulk Delete

Sep 16, 2013

The requirement is: I should allow single row delete from a table but not bulk delete. An audit table should get updated if there is any single delete or single update. So I wrote the triggers as follows: for single and bulk delete

ALTER TRIGGER [dbo].[TRG_Delete_Bulk_tbl_attendance]
ON [dbo].[tbl_attendance]
AFTER DELETE
AS

[code]...

When I try to run the website, the database error I am getting is:Transaction count after EXECUTE indicates that a COMMIT or ROLLBACK TRANSACTION statement is missing. Previous count = 0, current count = 1.

Delete Doesn't Delete Rows, But @@ROWCOUNT Says It Did

Aug 20, 2007

I ran the following query in Query Analyzer on a machine running SQL Server 2000. I'm attempting to delete from a linked server running SQL Server 2005:

DELETE FROM sql2005.production.dbo.products
WHERE vendor='Foo'
AND productId NOT IN
(
SELECT productId FROM sql2000.staging.dbo.fooProductList
)

The status message (and @@ROWCOUNT) told me 8 rows were affected, but nothing was actually deleted; when I ran a SELECT with the same criteria as the DELETE, all 8 rows are still there. So, once more I tried the DELETE command. This time it told me 7 rows were affected; when I ran the SELECT again, 5 of the rows were still there. Finally, after running this exact same DELETE query 5 times, I was able to remove all 8 rows. Each time it would tell me that a different number of rows had been deleted, and in no case was that number accurate.

I've never seen anything like this before. Neither of the tables involved were undergoing any other changes. There's no replication going on, or anything else that should introduce any delays. And I run queries like this all day, involving every thinkable combination of 2000 and 2005 servers, that don't give me any trouble.

Does anyone have suggestions on what might cause this sort of behavior?

Cannot Amend Or Delete Subscription And Cannot Delete Report.

Nov 20, 2007



Hi,

I have a problem with one report on my server. A user has requested that I exclude him from receiving a timed email subscription to several reports. I was able to amend all the subscriptions except one. When I try to remove his email address from the subscription I receive this error:

An internal error occurred on the report server. See the error log for more details. (rsInternalError) Get Online Help







For more information about this error navigate to the report server on the local server machine, or enable remote errors


Online no help couldn't offer any advice at all, so I thought I'd just delete the subscription and recreate it again, but I receive the same message. "Okay, no problem, I'll just delete the report and redeploy it and set up the subscription so all the other users aren't affected", says I. "Oh, no!", says the report server, and then it give me this message:





System.Web.Services.Protocols.SoapException: Server was unable to process request. ---> System.Data.SqlClient.SqlException: Only members of sysadmin role are allowed to update or delete jobs owned by a different login. at System.Data.SqlClient.SqlConnection.OnError(SqlException exception, Boolean breakConnection) at System.Data.SqlClient.SqlInternalConnection.OnError(SqlException exception, Boolean breakConnection) at System.Data.SqlClient.TdsParser.ThrowExceptionAndWarning(TdsParserStateObject stateObj) at System.Data.SqlClient.TdsParser.Run(RunBehavior runBehavior, SqlCommand cmdHandler, SqlDataReader dataStream, BulkCopySimpleResultSet bulkCopyHandler, TdsParserStateObject stateObj) at System.Data.SqlClient.SqlCommand.FinishExecuteReader(SqlDataReader ds, RunBehavior runBehavior, String resetOptionsString) at System.Data.SqlClient.SqlCommand.RunExecuteReaderTds(CommandBehavior cmdBehavior, RunBehavior runBehavior, Boolean returnStream, Boolean async) at System.Data.SqlClient.SqlCommand.RunExecuteReader(CommandBehavior cmdBehavior, RunBehavior runBehavior, Boolean returnStream, String method, DbAsyncResult result) at System.Data.SqlClient.SqlCommand.InternalExecuteNonQuery(DbAsyncResult result, String methodName, Boolean sendToPipe) at System.Data.SqlClient.SqlCommand.ExecuteNonQuery() at Microsoft.ReportingServices.Library.InstrumentedSqlCommand.ExecuteNonQuery() at Microsoft.ReportingServices.Library.DBInterface.DeleteObject(String objectName) at Microsoft.ReportingServices.Library.RSService._DeleteItem(String item) at Microsoft.ReportingServices.Library.RSService.ExecuteBatch(Guid batchId) at Microsoft.ReportingServices.WebServer.ReportingService2005.ExecuteBatch() --- End of inner exception stack trace ---



What's even weirder is that I'm the owner and creator of the report and I'm a system admin and content manager on the report server and I set up the subscription when the report was initially deployed. Surely I should have sufficient rights to fart around with this subscription/report as I see fit?

I have rebooted the server, redeployed the report, checked credentials on the data source and tried amending and deleting from both the report manager and management studio but still I am prevented from doing so.

Any help would be much appreciated.

Thanks in advance,

Paul

GO


Suddenly this constraint was being violated with the change


ALTER TABLE [dbo].[ClaimsReceivedPayorServices] ADD CONSTRAINT [FK_ClaimsReceivedPayorServices_CLAIMSRECEIVEDPAYOR S] FOREIGN KEY
(
[ClmRecdPyID]
) REFERENCES [CLAIMSRECEIVEDPAYORS] (
[CLMRECPYID]
)


Is the delete on ClaimsReceivedPayors starting before the delete on ClaimsreceivedPayorServices finishes? If so why would it matter between the join and subquery? This one is making me depressed because I can not explain it.

To Delete Or Not To Delete - DESIGN ISSUE!

Apr 3, 2008

Hi all

Need some advice solving a little problem I have with my database!

Current setup:

I have a person table that is made up of 39 columns. I also allow for person records to be deleted but I do this by having another table I call LogicallyDeletedrecords. This table is made up of the PersonId, Reason for deletion/suppression and a date time stamp. To access Live records I created a view based on my Person table which contains a WHERE clause to exclude records that exist in the LogicallyDeletedrecords. Similarly, I have another view DeadPersonData which contains Person records that have been removed. Hope it all makes sense so far! Now on to my worries!

The problem:

My Person table contains 9+ million records. The LogicallyDeletedrecords table has 500k+ but I anticipate further growth over the coming weeks/months. My worry is that my LivePersonData view will be too slow to access as my LogicallyDeletedrecords table grows. What’s more, as part of my Load routine, I have to make sure that Person data loaded on to the system is excluded if that same person exists as a deleted member. Both of these actions could slow down my system as the deleted table grows.

My thoughts:

I’ve been thinking of physically deleting dead Person records from my person table (possibly creating an archive table to hold them). But then if I delete them how do I cross check the details when new Person details get loaded?! As I said, my current LogicallyDeletedrecords table holds the PersonId, ReasonDeleted and CreationStamp. The only way is to add further columns which I use to match Person Details?

Any design suggestions would be welcome!

SQL Duplicates

Mar 2, 2006

I need some help.
I have created a database that looks like the following:
FirstName Table link to Main Table.
I have created a Stored procedure that looks like this:
Create procedure dbo.StoredProcedure
(
   @FirstName   varchar(20)
)
Declare FirstNameID int
Insert Into Main Table
(
FirstName
)
Values
(
@FirstName
)
Select @FirstNameID = Scope_Identity()
How could I redesign this to check if a value exists and if it exists then simply use that value instead of creating a new duplicate value?
 
Thanks!!

Getting Rid Of Duplicates

Jun 27, 2001

I have a dilema..... I have a databas eof about 60,000 users and i need to get rid of those users where there is a duplicate email address. I have written an asp utilty that works but is far too taxing on our little server and i thinkk itwill kill it. what it does is for each email address it compares it against all the others.... so for each address it checks against 60,000 other records 60,000 times.... you know what i mean. its pretty phucked.... i tested it on just one record and took about 5mins.

anyway ive been trying to do it in SQL with no luck

here is a simplified version of my dilema


*****
NAMEEMAILAGE
tomtom@mail23
tombomb tom@mail23
petepete@email23
davecool@mail21
stevesteve@mail17
marycool@mail89
thomas tom@mail13
richrich@mail65
richdick@mail65
tomtom@mail23
tomtom@mail23

so what i want to do is cut it down so there are no duplicate email addresses. I want the table looking like this:

*****
NAMEEMAILAGE
tomtom@mail23
petepete@email23
davecool@mail21
stevesteve@mail17
richrich@mail65
richdick@mail65

Can you think of a way to do this?

i tried the following but it gets rid of duplicates of other fields which is not what i want to do

CREATE table distinct_records
SELECT name, Email, Age
FROM duplicate_records
GROUP BY name, Email, Age;

any ideas guys?

thanks

Hi,
This is the query which shows me the duplicates
Some of the records have more than one records
I would like to know how to delete the extra records so that I will end up with one record per row.

select
Pricing_Source,
VaR_Identifier,
Price_Date,
PX_Last,
Count(*) as 'count'
from
tblPricesClean
group by
Pricing_Source,
VaR_Identifier,
Price_Date,
PX_Last
having count(*) > 1
order by
count desc

Hi,

Is there a way to find duplicates in one field? For example my query has person_nbr and for each person_nbr on one day they could have used multiple payer_names. I want to be able to count each person_nbr one time but also I want to group by description(which is the name of the provider) and by payer name to see how many person's that the provider seen with each payer. My problem is that if the person had more than one payer they are counted twice. Is there some type of aggregate function to use the first payer in the list??

With PersonMIA (person_id,person_nbr,first_name,last_name,date_of_birth) as
(
select distinct person_id,person_nbr,first_name,last_name,date_of_birth from
(select count(*) as countenc,a.person_id,a.person_nbr,
a.first_name,a.last_name,
a.date_of_birth
from person a
join patient_encounter b on a.person_id = b.person_id
group by a.person_id,a.person_nbr,a.first_name,a.last_name,a.date_of_birth )tmp
where tmp.countenc <=1
)
select person_nbr,payer_name,first_name,last_name,description,year(create_timestamp),create_timestamp
from
(
select distinct c.description,tmp.person_id,tmp.person_nbr,tmp.first_name,
tmp.last_name,tmp.date_of_birth,d.payer_name,b.create_timestamp
from PersonMIA tmp
join person a on a.person_id = tmp.person_id
join patient_encounter b on a.person_id = b.person_id
join provider_mstr c on b.rendering_provider_id = c.provider_id
join person_payer d on tmp.person_id = d.person_id
where c.description = 'Leon MD, Enrique'
group by c.description,tmp.person_id,tmp.person_nbr,tmp.first_name,tmp.last_name,
tmp.date_of_birth,d.payer_name,b.create_timestamp
)tmp2
where year(create_timestamp) IN (2005,2006)
group by person_nbr,payer_name,first_name,last_name,description,create_timestamp

Thanks in Advance!

Hi,
I'll see if I can explain this clearly. The query below
selects rows from the "hdr_ctl_nbr_status" table if the value in the field "tcn" from that table is found in the table "temp_tcn". I want all fields from the "hdr_ctl_nbr_status" table to be selected BUT only one row. In other words for a tcn with a value "12345678" there are 10 rows returned from the hdr_ctl_nbr_status table, I want only 1. Is there a way I can use SELECT DISTINCT to do this ? I know this usually functions on one or more fields but I want the DISTINCT to be on tcn only BUT return all fields in the query.

Select h.*,'' from hdr_ctl_nbr_status as h WITH (NOLOCK)
where h.tcn in (select tcn from temp_tcn)

Thanks, sorry if this is too confusing. Jeff

No Duplicates Please

Mar 10, 2008

Hi, All,

I have two columns of int data in the a table, as my example data shows below.

I want my data returned to be something like those in #test3, but my question is this, how can I do it without using #test2 and #test3?

By the way, the business requirement doesn't care it's min/max or any ID when one side has duplicated values.

Thanks!


Use tempdb
Go

if object_ID ('#test') is not null drop table #test

create table #test (col1 int, col2 int)
insert into #test
Select 123, 222 union
Select 124, 222 union
Select 125, 222 union
Select 111, 223 union
Select 111, 224

if object_ID ('#test2') is not null drop table #test2
create table #test2 (col1 int, col2 int)
Insert into #test2
Select distinct col1, min(col2) from #test group by col1


if object_ID ('#test3') is not null drop table #test3
create table #test3 (col1 int, col2 int)
Insert into #test3
Select min(col1), col2 from #test2 group by col2

Select * from #test3

Msg 512 But No Duplicates!?!

Jul 28, 2005

I am attempting to execute the Stored Procedure at the foot of thismessage. The Stored Procedure runs correctly about 1550 times, butreceive the following error three times:Server: Msg 512, Level 16, State 1, Procedure BackFillNetworkHours,Line 68Subquery returned more than 1 value. This is not permitted when thesubquery follows =, !=, <, <= , >, >= or when the subquery is used asan expression.I've done some digging, and the error message is moderatelyself-explanatory.The problem is that there is no Line 68 in the Stored Procedure. It'sthe comment line:-- Need to find out how many hours the employee is scheduled etc.Also, there are no duplicate records in the Employee table nor theWeeklyProfile table. At least I assume so - if the following SQL todetect duplicates is correct!SELECT E.*FROMEmployee Ejoin(select EmployeeIDfromEmployeeGroup by EmployeeIDhaving count(*) > 1) as E2On(E.EmployeeID = E2.EmployeeID)SELECTW.*FROMWeekProfile Wjoin(SelectWeekProfileIDFROMWeekProfileGROUP BYEmployeeID, MondayHours, WeekProfileIDHAVING COUNT(*) > 1) AS W2ONW.WeekProfileID = W2.WeekProfileIDNOTE: In the second statement, I have tried for MondayHours thruFridayHours.Anyone got any ideas?
