Stop Inserting Duplicate Entries

Sep 10, 2007

Hi I am trying to insert entries in a table which has a composite primary key and i am inserting it on UID basis.

INSERT INTO TABLE_B (TABLE_B_UID,NUM_MIN, NUM_MAX,BIN, REGN_CD, PROD_CD, CARD)
(SELECT UID,LEFT(NUM_MIN,16),LEFT(NUM_MAX,16),BIN, REGN_CD, PROD_CD, CARD FROM TABLE_A WHERE UID NOT IN (SELECT TABLE_B_UID FROM TABLE B))

When i insert it tries to insert a duplicate entries and gives me an error. Since I am new to SQL SERVER 2000 i need some help. I tried IF NOT EXISTS, EXCEPT but i guess i am wrong at the syntax.

Can anybody help me out?

Duplicate Entries

Mar 28, 2006

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

Duplicate Entries

Feb 7, 2007

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

I have an issue where certain parts of data are repeated several times after i create my query. Without providing my SQL code for now could anyone suggest possibly the main reason(s) for data being duplicated?

Thanks

Remove Duplicate Entries

May 8, 2008

 

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
 

 <asp:SqlDataSource ID="SqlDataSource3" runat="server"ConnectionString="<%$ ConnectionStrings:LocalSqlServer %>"SelectCommand="SELECT Product.Product.productid,Product.Product.catid,Product.Product.name,Product.Product.smalltext,Product.Product.longtext,Product.Product.price,Product.ProductSpecial.saleprice, Product.ProductSpecial.feature,Product.ProductImage.imgId, Product.ProductImage.imgUrlFROM Product.ProductINNER JOIN Product.ProductSpecialON Product.ProductSpecial.productid = Product.Product.productidINNER JOIN Product.ProductImageON Product.Product.imgid = Product.ProductImage.imgId"></asp:SqlDataSource>

Dont Sum Duplicate Entries

Jan 2, 2008



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?

Prevent Duplicate Entries In A Table

Nov 11, 2003

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

Preventing Duplicate Database Entries

Jan 31, 2006

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#.

Check For Duplicate Entries In One Field

Oct 17, 2005

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 In Returned SQL Field

Jan 3, 2007

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!

Finding Duplicate Entries (with Different Keys)

Feb 8, 2007

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

I have a database being populated by hits to a program on a server.The problem is each client connection may require a few hits in a 1-2second time frame. This is resulting in multiple database entries -all exactly the same, except the event_id field, which isauto-numbered.I need a way to query the record w/out duplicates. That is, anyrecords exactly the same except event_id should only return one record.Is this possible??Thank you,Barry

Best Method Of Checking For Duplicate Entries In SQL Server

Aug 22, 2007

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.

Inserting Multiple Entries Against 1 Record

Jan 17, 2008

Hi All,

I'm using Microsoft SQL Server Management Studio with SQL Server 2005 (SP2).

I have not had much experience with t-SQL and iterative logic implementation through SQL, therefore I think my problem is fairly basic for most of the pros here.

Here it goes...

I have two tables at hand, TestTab1 and TestTab2.

TestTab1 contains two attributes (columns) namely account_name (nvarchar(50)) and entry_count (int). For all rows in TestTab1, account_name is unique, i.e. for each account_name there is only 1 row in TestTab1. This is my source table.

TestTab2 contains one attribute namely account_name (nvarchar(50)). This table is empty and is my destination table.

I need to insert X entries (rows) for each account_name into TestTab2 where X is the int value in entry_count againt each account_name in TestTab1.

In other words, I need to insert account_name into TestTab2 as many times as the number in entry_count indicates.

I tried reading through the documentation but the help was not friendly enough for me to understand how to implement this.

Looking forward to the pro support.

Thanks,

Writting Trigger Or Procedure To Delete Duplicate Entries In A Table?

Sep 3, 2007

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 Rule To Stop Duplicate Records

Nov 11, 1999

I have a table in a database that keeps getting duplicate records added to it.
Is there a way to set a rule so that if someone tries to add a duplicate record for that field, it will stop the record from going in?

I know creating an index would be the proper way to do this but:

1. The application does not belong to us.
2. Duplicates already exist in the table for the database.

Basically I am trying to do the most without making alot of changes to the database.

Any help would be appreciated.

Inserting Duplicate Data

Jul 20, 2005

This is probably a silly question to most of you, but I'm in the processof splitting off years from a large DB to several smaller ones. Some ofthe existing smaller DBs already have most of the data for theirrespective years. But some of the same data is also on the source DB.If I simply do an insert keying on the year column, and a row beinginserted from the source DB already exists in the target DB, will aduplicate row be created?And if so, how can I avoid that?Thanks,John Steen*** Sent via Developersdex http://www.developersdex.com ***Don't just participate in USENET...get rewarded for it!

How Can I Prevent From Inserting Duplicate Data?

Dec 31, 2006

 
I have a table storing only 2 FKs, let's say PID, MID
Is there any way that I can check distinct data before row is added to this table?
For example, current data is
PID MID------------100 2001100 2005101 3002102 1009102 7523102 2449
If my query is about to insert PID 100, MID 2001, since it's existing data, i don't want to add it. Can I use trigger to solve this issue?
 
Thanks.

Searching A Column For A Value To Avoid Inserting A Duplicate Value

Jul 17, 2007

Hi there, newbie here.
I'm building a web application that allows for tagging of items, using ASP.NET 2.0, C# and SQL Server.
I have my USERS, ITEMS and TAGS separated out into three tables, with an intersection table to connect them.
Imagine a user has found an item they are interested in and is about to tag it. They type their tag into a textbox and hit Enter.
Here's what I want to do:
I want to search the TagText column in my TAGS table, to see if the chosen tag is already in the table. If it is, the existing entry will be used in the new relationship the user is creating. Thus I avoid inserting a duplicate value in this column and save space. If the value is not already in the column, a new entry will be created.
Here's where I'm up to:
I can type a tag into a textbox and then feed it to a query, which returns any matches to a GridView control.
Now I'm stuck... I imagine I have to use "if else" scenario, but I'm unsure of the code I'll have to use. I also think that maybe ADO.NET could help me here, but I have not yet delved into this. Can anyone give me a few pointers to help me along?
 Cheers!

Inserting Of Duplicate Records Error Message

Jan 15, 2004

I would like to know what options I have with regards to trapping a duplicate record
before it tries to post to a SQL database. I have set the column to unique in SQL. But
when I try to use ASP and post a duplicate record I get a system error. I would like to
just create a referential error to notify the user that they cannot post a duplicate record
please try again. Any help would be greatly appreciated.

Multiple Session IDs Inserting Duplicate Records

May 6, 2015

Have a table that is used during a conversion. It is hit pretty heavily with inserts by mulitple session ids. For performance reasons I cannot add a unique constraint on the column that is getting duplicates (it is an encrypted cell in varbinary). 

I do not want duplicates in this Encrypted Column. So before each insert the insert programs reads the table and verifies that the Encrypted Column value does not already exist. But unfortunately several duplicates are falling through the cracks. What are my options for not allowing duplicates?

Stored Procedure Inserting Duplicate Records Randomly

Feb 1, 2005

I have a web app that calculates tax filing status and then stores data about the person.

Facts
The insert is done through a stored procedure.
All the sites that this program is being used are connecting through a VPN so this is not an external site.
The duplicate records are coming from multiple sites (I am capturing there IP address).
I am getting a duplicate about 3 or 4 times a day out of maybe 300 record inserts.

Any help would be greatly appreciated.

There are many sqlcmdInsert.Parameters("@item").Value =

cnTaxInTake.Open()
sqlcmdInsert.ExecuteNonQuery()
cnTaxInTake.Close()

And that is it.

To Display An Alert Message While Inserting A Duplicate Record

Dec 21, 2005

I am duplicating a record from my asp.net page in to the database. When i click on save I am getting the following error message
Violation of PRIMARY KEY constraint 'PK_clientinfo'. Cannot insert duplicate key in object 'clientinfo'. The statement has been terminated.
The above message i am getting since i have tried to duplicate the clientname field of my table which is set as the primary key.
What i want is instead of this message in the browser i need to display an alert saying "the clientname entered already exists" by checking the value from the database.
Here is my code. pls modify it to achieve the said problem
if(Page.IsValid==true)    {           conn.Open();     SqlCommand cmd = new SqlCommand("insert into clientinfo (client_name, address) values ('"+txtclientname.Text+"', '"+txtaddress.Text+"')", conn);     cmd.ExecuteNonQuery();     conn.Close();     BindData();     txtclear();      System.Web.HttpContext.Current.Response.Write("<script>alert('New Record Added!');</script>");     Response.Redirect("Clientinfo.aspx");    }
