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?

Hi! I am joining 3 tables in SQL , I am getting the results I want exept it's duplicated. So the resultinmg table fom my stored procedure has 3 rows that have the same bulletin. How do I filter the storedprocedure to output only the rows that don't have duplicate entries for the column 'Bulletin' Thanks.
Here is my stored procedure:PROCEDURE [dbo].[spGetCompBulletins]
@Userid uniqueidentifier OUTPUT,@DisplayName varchar(200)
AS
SELECT *
FROM dbo.UserProfile INNER JOIN
dbo.bulletins ON dbo.UserProfile.UserId = dbo.bulletins.Userid INNER JOINdbo.Associations ON dbo.Associations.BusinessID = dbo.bulletins.Userid WHERE UserProfile.DisplayName=@DisplayName

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

Someone ran an update statement multiple times so their are multiple entries in the table. What is the quickest way to track down the multiple entries? I would only want to see where timein and timeoff exist in the table multiple times for the same id. So this would be a duplicate
EntryID -- ID -- timein -- timeoff

The following is the trigger which create a row in the audit table when a single deletion is occurred.
ALTER TRIGGER [dbo].[TRG_Delete_tbl_attendance]
ON [dbo].[tbl_attendance]
AFTER DELETE
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
[code]....
I am trying to create a trigger which should prevent the bulk deletion. The following is the trigger which I have written, it is preventing the bulk deletion. But the problem is, it is removing the single deletion entries in the audit table. I want audit table to hold back the single deletion entries without allowing the bult deletion
ALTER TRIGGER [dbo].[TRG_Delete_Bulk_tbl_attendance]
ON [dbo].[tbl_attendance]
AFTER DELETE
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;

I have a table with more than 1000 records. The columns look like this
Import id | Reference | Date | Username | Filename
Some of the rows are duplicates except for the fact that they have different values for the first column alone (import id)
11111 test 21-07-2015 xxxxxx yyyyyy
22222 test 21-07-2015 xxxxxx yyyyyy
Is it possible to delete these kind of duplicate rows by ignoring the import id ?

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

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 3 tables...TableA, TableB, TableC TableA - Personal InformationPersonalInfoId (Primary) , First Name,Last NameTableB - Personal Information To Department IDReferenceID, FKPersonalInfoId, FKDepartmentIdTableC - DepartmentDepartmentId, DepartmentNameI am coding Asp.Net VB using VWD express with Sql Server Express. I know how to create a stored procedure to delete, insert and even update a record in TableA, TableB, TableC respectively.If I need to delete a record in TableC, which has a related record in TableB, I have read that I need to use a Trigger. I never have used a Trigger and it is new to me. Can someone point me a way on how to use one in this case of my deleting scenario. Pretty much, if a user clicks on a delete button, and deletes a record in my TableC, I dont want a FKDpartmentId in my TableB that doesnt exist anymore because it was deleted in TableC or prevent a user from deleting that record till the relationship in TableB is no longer valid. In the same vain, If I have a input form which ask the user to enter their First Name and Last Name and Department, i would like to add those records in TableA for First and Last Name, TableB for the Department. Once again, how do I create a Trigger that if I insert a record in Table A to also insert the information for Department in Table B, if its successful in my stored procedure. Hope that made sense.Thanks.

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>

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

Is there another option I can do this?

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#.

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.

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!

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

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

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.
