Removing Duplicate Entries In SQL Field

Duplicate Entries In A Field
I have a field called RegId. RegId is of datatype NVARCHAR (20).

RegId
-----
12322
2122111
23423
etc
etc

I want to run a query to find out if there are duplicate entries in this field.

Any ideas on how I can achieve this?

Thanks in advance,

Anthony

Duplicate Entries In Returned SQL Field
Hi All !

Below is a snippet of MS SQL inside ASP 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 back green, red, blue, and yellow which is correct. On another similar search 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. I hope this makes sense.

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

Thanks in Advance!

Check For Duplicate Entries In One Field
Obviously, I'm a complete n00b at SQL.

I have a table in Access 2003 with about 6,000 records and there are about 20 records that have duplicate data in the first field (CompID).

I'm trying to make the first field my primary key, so I need to fix these duplicate entry.

I could export to Excel and fix the problem that way, but in the interest of learning SQL I want to figure out how to do it properly.

Thanks in advance for what is hopefully a simple answer.

Duplicate Entries
I have an application that allows the user to enter data into a table. There are multiple users so I put in some code that, I thought, would keep 2 users from creating a new record at the same time. The IDs for the records are identical and this is causing a problem.

The IDs are in the format of ####-mmyy. at the start of each month the #### part goes back to 1.

We tried a test today where we had 2 users click on the New button at exactly the same time. The IDs that were created were identical. Is there anyway on the database that I can prevent this from happening?

Here is how I create the new record id:

I get the MAX(ID) from the table
I add 1 to the ID and then insert a new record with the new ID into the table.

Any help is appreciated.

Thanks,
enak

Duplicate Entries
I'm extracting data from a log (log_history) of patients where nurses perform various actions on a call, such as assessing and reassessing, despatching etc. This is the script:

Select
L.URN,
LH.THE_TIMESTAMP,
LH.ACTION_TYPE,
LH.ACTION_BY,
LH.ACTION_REQD,
LH.NOTE,
em.position_type_ref
From
LOG L
Join Log_history LH on (L.URN = LH.LOG_URN)
left outer join employee em on (em.code = LH.action_by)
Where
(L.Taken_at >= :DateFrom and L.Taken_at <= :DateTo) and (LH.ACTION_TYPE = 'D') and (em.position_type_ref ='NU')

Order By
L.URN ASC, LH.THE_TIMESTAMP DESC



The result I get shows duplicate 'timestamp' entries and I only want to return unique timestamp entries. Does anyone have any ideas. I'm self taught and have hit a wall

Remove Duplicate Entries
 

I am a newb at ms sql and was hoping someone could help me
eliminate duplicate PRODUCT.PRODUCT from this statement.  I have tried using DISTINCT with the same results.The ProductImage table is causing this because
the duplicates are from the PRODUCT.PRODUCT that have more than 1 image.



 If anyone could rewrite this statement so I can learn from this, it would
be most appreciated!


 


Thank you for your time

Dont Sum Duplicate Entries
 

Hi.
I have a table with Login and Logoff Time of users, but there could be duplicate Logtimes in the dataset, but for
different products. Because of this I cant do a distinct in the dataset. I need the Product and some other details in my Report.
 
I tried to make two datasets. One for the Select distinct and one for the other.
 
But the Problem is:
in my report, I need a table, where I make the Sum of the Logintime a day and in another column I calculate with data from the other dataset.(Logtime + data from dataset2). But this doesnt work, so I think, that is it not possible to join 2 dataset in one table.
 
datetime Login     | datetime Logout   | Product
11.12.2007 10:15 | 11.12.2007 12:15 | p1
11.12.2007 10:15 | 11.12.2007 12:15 | p2
11.12.2007 12:19 | 11.12.2007 15:15 | p2
 
Is there another option I can do this?

Preventing Duplicate Database Entries
Hi all.. I've been scouring the forums for about 6 hours to no
avail.  This is a really simple question.  I'm trying to have
a registration page that lets the user input name, email, desired
username, and password.  I want to check the username and email
fields to make sure ppl cannot sign up twice.  So from what I've
gathered I have a couple of options:

1) i can set up a unique constraint on the database columns,
2) i can run a select statement before inserting,
3) i can store the whole database column in a variable then search through it.

My question is how to do option 2?  All of my transactions are through a sqldatasource object in c#.

Prevent Duplicate Entries In A Table
I have an ASP.Net Web appplication with a Back-End SQL DB. There are 3 Tables; Users, Groups, and GroupMember.

The GroupMember table is used to link Users to Groups and consists of just two fields; userID and GroupID.

Here is a sample of some data:

User1 Group1
User1 Group2
User2 Group2
User3 Group1
User3 Group3

Users can belong to multiple Groups. However, you shouldn't be able to have the same user and group comobination more than once. for example:

User1 Group1
User2 Group2
User1 Group1

I can stop this kind of duplicate data entry by doing a lookup first (using asp.net) to see if the entry already exists but this seems cumbersome.

Is there a simpler way to prevent duplicate entries in a table using sql?

Thanks a lot,

Chris

That is, anyrecords exactly the same except event_id should only return one record.Is this possible??Thank you,Barry

Duplicate Backup Entries Using SQLMAINT
I would appreciate someone pointing me in the right direction to resolve a backup anomaly
were currently experiencing. We recently installed SQL Server 6.5 and noticed that although
our scheduled tasks were running as requested the DelBkUps parameter wasn`t working. In
addition we noticed that the backup files that were created didn`t have the time portion
appended to date (suffix of backup name). The steps we took to resolve this was to install
Service Pack 3. After the install the following was observed: 1) DelBkUps parameter started to
work 2) duplicate backup entries were created, the only difference being that for one of
the entries the time portion was still missing (ie. apps_db_dump.19980722 instead
of apps_db_dump.199807221840). Letting in cycle through for a week didn`t have any affect.
The final observation is that for scheduled tasks that occur more than once/day (i.e. transaction
dump every 8 hours) no duplicate backup entries are created and file suffix is correct
(i.e apps_db_dump.199807221840).

.......thanks,,,,brad

Finding Duplicate Entries (with Different Keys)
Yet another simple query that is eluding me. I need to find records in a table that have the same first name and last name. Because the table has a primaty key, these people were entered twice or they share the same first and last name.

How could you query this:

ID fname lname
10001 Bill Jones
10002 Joe Smith
10003 Sue Jenkins
10004 John Sanders
10005 Joe Smith
10006 Harrold Simpson
10007 Sue Jenkins
10008 Sam Worden

and get a result set of this:

ID fname lname
10002 Joe Smith
10005 Joe Smith
10003 Sue Jenkins

Best Method Of Checking For Duplicate Entries In SQL Server
Here is my situation.  I have a table in my application that pairs users with cars they like.  We'll call this table Favorites.  A user can browse the site and they can designate as many cars they want as favorites.  For example, a user can go to the Honda Accord page and add that as a favorite car and then go to the Toyota Camry page and add that as a favorite car.  However, if he/she goes to that Honda Accord page and tries to click the "Add to Favorites" button again, at the present state of my application, it will just add another entry into the Favorites table with a duplicate pairing.  So, if I were to datalist the table to generate a listing of all favorites belonging to a certain user, he/she may potentially be returned with superfluous duplicate entries.  Not to mention, taking up valuable database space and not looking very professional.
In my Favorites table, the 3 fields are.....favoriteId (set as primary key)userIdcarId
I've been thinking about this for awhile and I've come up with 2 solutions.  I'm a newbie to ASP.NET/programming so I don't have enough insight to make a decision or to even think up of other alternatives.
1) Check proactively by doing a.....SELECT favoriteID FROM Favorites WHERE userId = x and carId = y  (where x and y are variables)If I get a null return, it means I can go ahead and let the user add the car as a favorite in the database.  If I get a valid value, then it means there already exists the same pairing, so I exit out without updating the table.
2) Check reactively by forcing an exception whenever a user tries to enter a duplicate pairing.  I'm not sure how to do this, but perhaps, instead of making "favoriteId" a primary key, perhaps, I can make a primary key pairing of "userId" and "carId".  And by trying to do an insert with a primary key that already exists, we know it won't work since primary keys by definition are unique.
Now, I expect some concurrent users on my site, so I must take into consideration pros and cons of each and determine which is more efficient.  Checking proactively will force a check even if the table does not contain a duplicate pairing of user and car.  However, having a duplicate primary key may be more expensive from a database point of view and may slow down lookups, etc.  Or maybe neither has significant benefits, in which case, I rather go with proactive, since I've already coded it and it works fine.  Or maybe there is a third alternative, which I did not think.  Which method do programmers usually take and which is a better practice?
TIA for your help.

Writting Trigger Or Procedure To Delete Duplicate Entries In A Table?
I am using Sql Server 2000.
I have a customer table with fields - CustId, Name, Address, City, StdCode, Phone.
I used to insert entries in this table from an excel file.
One excel file will contain thousands of customer.
In this table combination of StdCode and Phone should not be repeated.
If I do it in my VB.Net coding.then application gets drastically slow.
So I want to write a procedure or trigger for this.
Here what I will do, I will send all records into database then this trigger or procedure will check for
any existing entry of combination of StdCode and phone. If entry exists then this will delete new entry
or will not allow this new entry.
Is this possible to do using Trigger or stored procedure?

CREATE TABLE DUPLICATE OBJECT/DUPLICATE FIELD NAME ERROR Msg 2714
Hello Everyone:
 
I am using the Import/Export wizard to import data from an ODBC data source. This can only be done from a query to specify the data to transfer.
 
When I try to create the tables, for the query, I am getting the following error:
 



Msg 2714, Level 16, State 4, Line 12

There is already an object named 'UserID' in the database.

Msg 1750, Level 16, State 0, Line 12

Could not create constraint. See previous errors.

 
I have duplicated this error with the following script:
 

USE [testing]

IF OBJECT_ID ('[testing].[dbo].[users1]', 'U') IS NOT NULL

DROP TABLE [testing].[dbo].[users1]

CREATE TABLE [testing].[dbo].[users1] (

[UserID] bigint NOT NULL,

[Name] nvarchar(25) NULL,

CONSTRAINT [UserID] PRIMARY KEY (UserID)

)

IF OBJECT_ID ('[testing].[dbo].[users2]', 'U') IS NOT NULL

DROP TABLE [testing].[dbo].[users2]

CREATE TABLE [testing].[dbo].[users2] (

[UserID] bigint NOT NULL,

[Name] nvarchar(25) NULL,

CONSTRAINT [UserID] PRIMARY KEY (UserID)

)

IF OBJECT_ID ('[testing].[dbo].[users3]', 'U') IS NOT NULL

DROP TABLE [testing].[dbo].[users3]

CREATE TABLE [testing].[dbo].[users3] (

[UserID] bigint NOT NULL,

[Name] nvarchar(25) NULL,

CONSTRAINT [UserID] PRIMARY KEY (UserID)

)

 

I have searched the "2714 duplicate error msg," but have found references to duplicate table names, rather than multiple field names or column name duplicate errors, within a database.
 
I think that the schema is only allowing a single UserID primary key.
 
How do I fix this?
 
TIA

go
insert into test values(1, 'abc')
go
insert into test values(2, 'abc')
go

Removing Duplicate In Listbox
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.

Removing Duplicate Records
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.

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:- 




forumid

0  I want all the rows from the Forums,Topics and Threads table and the row with the maximum date (the last post date of the message) from the Messages table as shown above. 
When I use the query by using only three tables namely Forums,Topics and Threads, I get the correct result. The query is as:- 
SELECT Topics.forumid AS ForumID,Forums.name AS ForumName,Topics.topicid as TopicID,Topics.name as TopicName,
LastPosts.author AS Author,LastPosts.lastpostdate AS LastPost,
(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, Threads.lastpostdate, Threads.author FROM Threads
             INNER JOIN Topics ON Topics.topicid = Threads.topicid
             WHERE Threads.lastpostdate IN (SELECT MAX(lastpostdate) FROM threads WHERE Topics.topicid = Threads.topicid)
             ) AS LastPosts
             ON LastPosts.forumid = Topics.forumid AND LastPosts.topicid = Topics.topicid 
Whose result set is as:-

A Basic Question: Removing Duplicate Results From Max Function
Hi,Say I have a table Job with columns name, date, salary . I want to getthe name ,date and salary for the date when that person earned maximumsalary. I am using something likeSELECT X.name,X.date,X.salaryFROM job XWHERE X.salary IN(SELECT MAX(Y.salary) FROM job Y where Y.name= X.name);The problem is ; if a person earns maximum salary on two dates, both ofthe dates are printed. I just want to get any one of those two rows.I triedSELECT X.name,Min(X.date),X.salaryFROM job XWHERE X.salary IN(SELECT MAX(Y.salary) FROM job Y where Y.name= X.name);but it gives error.Can anybody please suggest a solution?Regards,Aamir

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

Comparing Similar Tables - Removing Duplicate Or Repeated Data
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

7680

12345
C01

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

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?

Finding Duplicate Entries In A &"smart&" Way - By Comparing First Two Words
What is the best way to compare two entries in a single table wherethe two fields are "almost" the same?For example, I would like to write a query that would compare thefirst two words in a "company" field. If they are the same, I wouldlike to output them.For example, "20th Century" and "20th Century Fox" in the companyfield would be the same.How do I do this? Do I need to use a cursor?

Removing Or Replacing Part Of A String In A Field?
Hi all I was wondering whether it was possible to remove or delete part of a String in a Field? Lets take for example I have:

- A Table called: Table_1
- A Field called: MyField
- MyField contains the value: Hello I am on the msdn forums

Is it possible to perform an UPDATE Query which deletes part of that sentence? If this was hard coded it would be rather simple but if the phrase was changing which would lead to the sentence also changing is it possible to do this?

Lets say I wanted to remove the part which said msdn forums. Then UPDATE the field again which should leave out the bit msdn forums.

Appreciate the responses, Onam.

Trying To Append A Field If An Insert Happens To Contain A Duplicate
I deliberately intend to add some duplicates to one of my tables. For eg

Job User IsAdmin

JobID 235User ID 1
JobID 235User ID 5
JobID 235User ID 9
JobID 235User ID 5
JobID 235User ID 2
JobID 235User ID 9
JobID 235User ID 10
JobID 235User ID 1

I know its bad practice to do such a thing but there is a genuine reason. What I need to do is to be able to have a SQL statement that appends true to the IsAdmin field whenever it encounters the next UserID thats happens to be a duplicate. Hence the above would look like:

Job User IsAdmin

JobID 235User ID 1
JobID 235User ID 5
JobID 235User ID 9
JobID 235User ID 5 True
JobID 235User ID 2
JobID 235User ID 9 True
JobID 235User ID 10
JobID 235User ID 1 True

Thanks

2 a b ab
2 b b bb


when i save this table modifying the pubid and pubcode as primary keys the following error displays...

Unable to create index 'PK_PUBS3'.
CREATE UNIQUE INDEX terminated because a duplicate key was found for index ID 1. Most significant primary key is '51'.
Could not create constraint. See previous errors.
The statement has been terminated.


what i understand is that on the primary key duplicates are not allowed how could i allow it?

thanks

Select Records That Do Not Duplicate On A Certain Field.
I am looking for some help in pulling certain people out of a table

This is the basic setup of my table


PK ID NAME MEETING
1 11111 Joe CLASS98
2 22222 Jane CLASS98
3 33333 Bob CLASS98
4 11111 Joe CLASS04
5 22222 Jane CLASS04
6 44444 Sally CLASS04

What I am wanting to do is Select only the people who attended CLASS98 but didn't attend CLASS04

I could just remove the CLASS04 people by sorting if I could just return the rows that do not duplicate the ID and meeting is either CLASS04 or CLASS98

Either way would get me to my goal.

Any help is GREATLY appreciated.

Thanks
Jimmyjoe

Query Returning Duplicate Field Names
I have a .NET program that can connect to either an Access 97 database or anSQL Server 7 database. In the database I have two tables which have a fieldcalled ID. When I run a query like "SELECT A.*, B.* FROM A, B", the queryreturns those fields as "A.ID" and "B.ID" when connected to Access 97, butas "ID" and "ID" in SQL Server 7. Is there anyway to get SQL Server toprepend the table name to the field name in a case like this and not returnduplicate field names like that without having to specify aliases for thefields?- Don

Group By Query To Find Duplicate Field Value
Hello,

Not sure how to do this. I think I need to use a Group By query. I have a "Products" table with the following fields:

Program#
Number
UPC
Item
Item#
Size
Dept

Everything is specific to the Program#. In other words, for every instance of a Program# there can be more than one Product, which is specified by the "Number" field. So: SELECT * FROM Product WHERE [Program#] = '12345' should return this:

12345 | 1 | 000012345678 | Cookies | 98765 | 12ct | Retail |
12345 | 2 | 000012345678 | Cake | 98765 | 12ct | Retail |
12345 | 3 | 000012345678 | Ice Cream | 98765 | 12ct | Retail |

However, some recordsets are returning like this:

12345 | 1 | 000012345678 | Cookies | 98765 | 12ct | Retail
12345 | 1 | 000012345678 | Cake | 98765 | 12ct | Retail
12345 | 2 | 000012345678 | Ice Cream | 98765 | 12ct | Retail

In which case I have to fix them (the "Number" field) with an update query sp they are numbered sequentially. Luckily, this doesn't happen very often.

Can someone help me with a query that will return only those records with duplicate values in the "Number" field? I am not sure how to construct this query which I will use as a stored procedure.

TIA,

.dbf File Import (duplicate Field Names)
I am importing a file creating by an application which exports the file into .dbf format.  Very unfortunately, this .dbf file can have fields with IDENTICAL column_names.  Utilizing ActiveX, I create an ado connection to the .dbf file using a visual foxpro drver.  However, and not unexpectantly, I can not do the 'select *' from the file if there are duplicate names.

Can anyone make recommendations here that might help?

Oh, this is SQL200 in case that impacts what you might advise!!!!

Why Duplicate Field &"LoweredEmail&" ...?
Hi,
in table aspnet_membership of ASPNETDB.mdb file, i saw a kind of duplicate field like "LoweredEmail" containing the same value as field "Email" (also in table users field "LoweredUsername" ..).
I guess it's for containing email in lowercase, but why those fields?
Thanks
