Query To Merge Duplicate Records

Jun 6, 2007

Hello,
I have the following Query:
1    declare @StartDate char(8)2    declare @EndDate char(8)3    set @StartDate = '20070601'4    set @EndDate = '20070630'5    SELECT Initials, [Position],  DATEDIFF(mi,[TimeOn],[TimeOff]) AS ProTime6    FROM LogTable WHERE 7    [TimeOn] BETWEEN @StartDate AND @EndDate AND8    [TimeOff] BETWEEN @StartDate AND @EndDate9    ORDER BY [Position],[Initials] ASC
The query returns the following data:
Position                                           Initials ProTime     -------------------------------------------------- -------- ----------- ACAD                                               JJ       127         ACAD                                               JJ       62          ACAD                                               KK       230         ACAD                                               KK       83          ACAD                                               KK       127         ACAD                                               TD       122         ACAD                                               TJ       127        
  
What I'm having trouble with is the fact that I need to return a results that has the totals for each set of initials for each position.  For Example, the final output that I'm looking to get is the following:
Postition                       Initials                 ProTime
ACAD                           JJ                       189ACAD                          KK                       440ACAD                          TD                        122ACAD                          TJ                         127
 Any assistance greatly appreciated.

Delete Duplicate Records

Oct 19, 2000

Sorry for the new thread.

I have a userprofile table. There are a lot of duplicate records in this table. e.g.

USERID-----LASTNAME---EMAILADDRESS----CREATEDATE
----------------------------------------------------------------------
1----------A-----------A@yahoo.com---------2000-09-05 16:07:00.000
2----------A-----------A@yahoo.com---------2000-09-10 16:07:00.000
3----------A-----------A@yahoo.com---------2000-09-15 16:07:00.000

Userid is auto number, lastname and emailaddress are PK.

I want to delete duplicate records. If lastname and emailaddress are the same, only keep a record which createdate is the most newest date. See above example I only want to the record which userid is 3. I have alreday created a code which I attached below. This code onle keep a record which userid is 1.

Anybody can help me to solve this problem? Thanks.

============== My current code ====================
delete from userprofile where userprofile.userid in
--list all rows that have duplicates
(select p.userid
from userprofile as p
where exists
(select lastname, emailaddress
from userprofile
where lastname = p.lastname and emailaddress = p.emailaddress
group by lastname, emailaddress
having count (userid)>1))
and userprofile.userid not in
--list on row from each set of duplicate
(select min(p.userid)
from userprofile as p
where exists
(select lastname, emailaddress
from userprofile
where lastname = p.lastname and emailaddress = p.emailaddress
group by lastname, emailaddress
having count (userid)>1)
group by lastname, emailaddress)

Delete Duplicate Records

May 7, 2008

Hello everyone,

I have a little dilemma. I have a table ALLTABLE that has duplicate records and I want to delete them. ALLTABLE has these columns with these values for example:

Policy Premium Class State Entity Number
ADC-WC-0010005-0 25476 63 31 1
ADC-WC-0010005-0 25476 63 31 2
ADC-WC-0010005-0 25476 63 31 3
ADC-WC-0010005-0 1457 63 29 4
ADC-WC-0010092-1 2322 63 37 1
ADC-WC-0010344-0 515 63 01 1
ADC-WC-0010344-0 515 63 01 2

As you can see there is some duplicates in the first 3 rows and the final 2 (the entity number is the only difference). I want the table to look like this:

Policy Premium Class State Entity Number
ADC-WC-0010005-0 25476 63 31 1
ADC-WC-0010005-0 1457 63 29 4
ADC-WC-0010092-1 2322 63 37 1
ADC-WC-0010344-0 515 63 01 1

Thank you so much for the help. It is really appreciated.

Have Duplicate Records, Can't Delete Extras!

Apr 9, 2008

I have inherited a database with no primary keys in it. :(

There are, of course, duplicate records by the "logical key", i.e., the list of columns that should have been used in a primary key, if they only had one. I can easily identify when I have duplicate records using group by and having clauses.  That's the easy part.I can identify duplicate records by "key columns" and the subset of those records that are "identical duplicates on all columns".  I need to delete the "extra copies"

I can't do it by hand using sql server manager, it won't let me, because it recognizes that more than one row matches that row. In Oracle, I would use the pseudo-column "rowid", which would expose the internal identifier for the row.SqlServer doesn't appear to have this concept. is there another way other than creating an empty shadow table, copying all the distinct duplicate records into the shadow table, deleting all the duplicates in the old table, then copying the distinct duplicates back into the old table.

Unable To Delete Duplicate Records

Jul 7, 2007

I was importing records via DTSWizard, and I was having problems so I turned off Enforce Replicaton, Enforce FK Constraints on a couple of fields. I'm new with SQL Server so I'm not sure if this even caused the problem. (Do I need to turn these back on, or is this a Developer switch of some kind?)



The end result left me with duplicate records in the table, and I'm not able to delete any of them. This is the Error I got...



A problem occurred attempting to delete row 1.
Error Source: Microsoft.VisualStudio,Datatools.
Error Message: The row value(s) updated or deleted either do not make the row unique or they after multiple rows(2 rows).



If someone could tell me what I need to do so I can delete the records I'd really appreciate it.



Thanks,

Bill

SELECT Statement Listing Joined Records

Jan 18, 2005

I've searched high and low for info on how to do this... If anyone has an idea, I'd really appreciate it.

I have three tables: PEOPLE, PROJECTS, COMMENTS. I want users from the PEOPLE table to retrieve a list of PROJECTS and be able to add/edit COMMENTS on those projects.

The tables look like:

PEOPLE
people_id (primary key)
first_name
last_name

PROJECTS
projects_id (primary key)
project_title
project_summary

COMMENTS
comments_id (primary key)
projects_id (foreign key)
people_id (foreign key)
comment_detail

I'd like to be able to output something like what I have below, but I don't know how to loop over the comments/people within the select statement for the projects.

DESIRED OUTPUT

Project #1
Comment #1 by Person #1
Comment #2 by Person #3
Comment #3 by Person #8

Project #2
Comment #1 by Person #2
Comment #2 by Person #3
Comment #3 by Person #6

Etc...

I've done it before by just listing the projects and then providing a detail page with all the comments, but it's much less confusing to access all the comments from the same page, grouped by project.

Thanks in advance.

Tables Joined On Multiple Columns, Exclude Records Found In Table A

Nov 7, 2006

I'm using SQL server 200

Table A has columns CompressedProduct, Tool, Operation

Table B in a differnt database has columns ID, Product, Tool Operation

I cannot edit table A. I can select records from A and insert into B. And I can select only the records that are in both tables.

But I want to be able to select any records that are in table A but not in Table B.

ie. I want to select records from A where the combination of Product, Tool and Operaton does not appear in Table B, even if all 3 on their own do appear.

This code return all the records from A. I need to filter out the records found in Table B.

---------------------------------------------------------------------------------------------------------------------------------

SELECT ID, CompressedProduct, oq.Tool, oq.Operation FROM OPENQUERY (Lisa_Link,
'SELECT DISTINCT CompressedProduct, Tool, Operation FROM tblToolStatus ts
JOIN tblProduct p ON ts.ProductID = p.ProductID
JOIN tblTool t ON ts.ToolID = t.ToolID
JOIN tblOperation o ON ts.OperationID = o.OperationID
WHERE ts.ToolID=66

How Can I Delete All But One Instance Of A Duplicate Row?

Oct 7, 2004

I have several rows in a table that contain duplicate information. I want to trim them down to one instance per row, without other duplicates.

I have several columns, but only 2 of the columns are used to determine the "Identical Rows", however one of the other columns could also be used to determine which of the others are deleted.

Let's just say I have a table called DATA.
In DATA I have the following columns:
C1: ID/Key column (Unique numbers not associated with any other row)
C2: Specific Data column 1
C3: Specific Data Column 2
C3: Keeper if not null
C4: Misc Info
C5: Misc Info

Basically IF C2 & C3 are duplicated, then I want to keep one of these and ditch the others.

The row I want to keep is the one that has info in C4, but at times C4 does not have anything in it on any of them, at that point I just care about keeping one of the C2 & C3 Duplicate rows.

The other issue I face is C2 will always have something in it, but at times C3 will not and C4 will.

So I want to keep the one duplicate row that has the most info in it. At minimum, I want to always keep C2 & C3 if they both contain data.

For example, if I had the following duplicate rows:
(C2) red (C3) 123 (C4) XYZ
(C2) red (C3) 123 (C4) XYZ
(C2) red (C3) 123 (C4) XYZ
(C2) red (C3) (C4) XYZ
(C2) red (C3) 123 (C4)

I want to keep: (C2) red (C3) 123 (C4) XYZ

I have some rows that have three exact duplicates, some that have four, some that have two.

How can I tell the Query Manager to delete all but one instance of each duplicate row?

I did do a query to find out how many duplicates I have and found it to be around 232,000+. Basically I will be cutting this in half if I can get rid of the duplicates.

I have read 30 different ways on many sites and I am now officially confused

Thank you for your help.

GROUP BY Table1.computerName, Table1.programName, Table1.version, Table1.publisher
HAVING Count(Table1.ID) > 1)
GROUP BY computerName, programName, version, publisher);

TABLE STRUCTURE::
ID computerName programName version publisher installDate
1 COMP1Microsoft .NET Framework 1.11.1.4322Microsoft 20050216
2 COMP1Windows XP Hotfix - KB89178120050110.17Microsoft NULL
3 COMP1Windows Media Player 10 NULL NULL NULL
4 COMP1Microsoft .NET Framework 1.11.1.4322Microsoft 02/16/2005

The duplicate records i am trying to delete are not truly duplicates, each record has a unique ID and install dates could vary. I am trying to identify duplicate records as identical (computerName + programName + version + publisher) See records 1 and 4 in table structure above... i dont care which of the duplicates is kept, as long as 1 is kept.

What I am looking for is either a completely new query which maybe optimized to run on a larger scale table or maybe just a performance tweak to my exisitng query??

Any help would be greatly appreciated!

Thanks.

Delete Duplicate Rows

Jan 27, 2014

declare @a1 table
(id int not null identity(1,1),
phone decimal(18,0),
adress nvarchar(100))
insert @a1
(phone,adress)

[Code] ....

id phone address
----------- --------------------------------------- ----------------------------------------------------------------------------------------------------
1 111 new york
2 111 new york
3 111 new york
4 222 maxico
5 222 mexico

select phone,count(phone) as say from @a1 group by phone having count(phone)>1

phone say
--------------------------------------- -----------
111 3
222 2

How can I remove duplicate phone. For example

after delete
select*from @a1
select*from @a1

id phone address
----------- --------------------------------------- ----------------------------------------------------------------------------------------------------
1 111 new york
4 222 maxico

I wrote this to show for example in my real table have 50000 rows and 1751 duplicate rows.
