I have recently been working on a project that requires one simple table to insert data into. The problem here is that all the data inserted must only access the database via stored procedure and I want to ensure that no duplicate data is inserted in the database.
I have done quite a bit of research for many ways to perform duplicate data testing from building temp tables and on, but nothing has really stood out to me yet. I would really like to find some information on how to perform duplicate data testing using a stored procedure that allows to test the data being inserted before it is saved to the database; therefore, when the user inserts the fields and clicks the insert button, the fields will be tested against the existing data (via stored procedure) within the database before being added.
This probably has been addressed before but I was unable to get the search to work properly on this site. I am needing a script/way of deleting all rows from a DB with the exception of one record left for each row that has duplicate column data. Example : Row 1 Field1 = 12345 Field2 =xxxxx Field 3=yyyyy Field4=zzzzz etc. Row 2 Field1 = 12345 Field2 =zzzzzz Field 3=xxxxxx Field4=yyyyyy etc. Row3 Field1 = 12345 Field2 =20202 Field 3=11111 Field4=zzzzz etc. Row 4 Field1 = 54321 Field2 =xxxxx Field 3=yyyyy Field4=zzzzz etc. Etc. Etc.
I want to be able to find the duplicates for Field1 and then delete all but 1 of those rows.( I don't care which one I keep just so only one is left.) The data in the other fields may or may not be unique.
I know how to find the duplicates it's just the deleting part I am having problems with. Any help would be much appreciated. Thanks,
Hello guys! Is it possible to duplicate a primary key? I would like my database to accept data with the same primary key. Is it possible? How do you declare ON DUPLICATE KEY UPDATE? Please help me. Thanks in advance.
I want to be able to duplicate a row of data in sql....Does anyone know if there is a sql command that will do that. I have a table with an auto increment primary key and I want to duplicate everything except the key into a new record.
I will need to stress test a sql server 6.5 test database by duplicating data. To do so, I need to know how to modify the primary key(which are numbers in character data type) to duplicate the data several times over. The primary key is character data.
What I have done ion the past is use insert statments -let's say 20 -- and then copy them and change the date in a text editor and change the primary key column and the other coluimns with thea replace of different letters and numbers. This is slow and tedious.
Does any one have a script I can run to do so?
Can I do this sql or do I need some sort of stored procedure? Any help would be appreciated. Thanks.
I have a table called emails with a field named emailaddress and some emailaddress are entered more than once. I want to be able to list all emailaddress just once. is there an sql statement that I could use to generate this.
Hello people, not sure how to do this. I have a unique Claim ID and when joined with the code table has 4 different Code ID and the Claim Amt is also unique to the Claim ID (One Claim Amnt per one Claim ID). I need all of these data for the report my problem is in getting the correct summation of the claim amt since this looks like I have 4 amounts of $1773.31 when in actuality there is only one. The Code ID is also part of the report parameter so I tried assigining the $ amount to just one of the Code ID but that will not work incase that particular Code ID is not selected in the parameter, the claim would read as a zero. Any help would be appreciated. Thanks
Claim ID: Code ID Claim Amt 07089000296 757.39 1773.31 07089000296 V05.3 1773.31 07089000296 V30.01 1773.31 07089000296 V72.19 1773.31
i have 2 tables not connected in any way but both have orderid filed (same filed). In one table this filed (and onther one) are keys, the second table dose not hace a key at all. The same order_id CAN repeat itself in each table. When i try to join the tables (some rows just in one table and some in both): Select tab1.name, tab1.orderid, tab2.sku from tab1 inner join tab2 on tab1.orderid=tab2.orderid The result i get is duplicate. each row is multiple. What I'm doing wrong?
Hi everybody, I'm migrating a table that has above 20,000 records and lot of duplication.Let's say an Employee table with multiple records having slight diference in the EmployeeName field.Now nobody would like to sit and manually identify them with such hugh number of records. Is there any way which would help me identify most of them and reduce the redundancy.
I have a query that for one reason or another produces duplicate information in the result set. I have tried using DISTINCT and GROUP BY to remove the duplicates but because of the nature of the data I cannot get this to work, here is an example fo the data I am working with
ID Name Add1 Add2 1 Matt 16 Nowhere St Glasgow 1 Matt 16 Nowhere St Glasgow, Scotland 2 Jim 23 Blue St G65 TX 3 Bill 45 Red St 3 Bill 45 red St London
The problem is that a user can have one or more addresses!! I would like to be able to remove the duplicates by keeping the first duplicate ID that appears and getting rid of the second one. Any ideas?
Hi. Not sure which section this request needs to be put in, but i'm relatively new to SQL.
I have 1 table which contains an user_id (autonumber), user_name, and user_profile.
I have 2 other tables: config_version (cv) and config (c)
These two tables both access the user table (us) to view the user_id (which is required).
I want to be able to view the user_names for both "cv" and "c" on a seperate page. Using the code below, i'm lost. I created what i wanted in MS Access with the use of a 2nd table (this might be easier to understand than my rant above). However, I don't want a 2nd table.
Can someone provide me with a function, or the "answer" to my problem?

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!
I have a table with 68 columns. If all the columns hold the same value except for one which is a datetime column I want to delete all but one of the duplicate rows. Preferably the latest one but that is not important. Can someone show me how to accomplish this?
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.
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?
I want to import data from a live site database into a development database (SQL Server 2005 Express) using the DTSWizard. Once I copy/paste the live database to my dev machine, I cant attach the live site database because it has the same name as the database on the dev site.A simple solution I would assume is to change one of the names. But I can't seem to change the "orignal file name". A backup/restore won't work for me because I made table/field changes to the dev database. Thanks --Dietrich
I'm working on a web app that needs to be able to take a row in the database and duplicate it, creating a new row in the same table with the same data except for the ID field and reference field.So basically: table1.row1 references table2.row1. I need to duplicate the data in table1.row1 (creating table1.row2) with the same reference to table2.row1.Is there any easy way to do this in SQL? I'm just looking for some ideas or a framework to accomplish this.
Our programs have and would like to continue keep the same data in multiple database. Example phone numbers. Us DBAs are tring to convince them not to.
Other than keeping the data current, what avantages are there to keep data in one location for multiple application to access.
Hi, I am new to SQL 7.0 and I have a large database but with some duplicate problems.
For example, in a table tblA we have columns as: userid, lname, fname, street, state... etc,
The problem is: The same user sometimes use different styles for his/her street and state (suppose he/she always use same userid, lname and fname), such as,
street State 7531 Plum Drive Maryland 7531 Plum Dr. MD
So a same user can produce a lot of duplicate user infomation. Can anybody help to elimenate this kind of duplicate data?
I just converted an old non-relational database into something that MS SQL likes. The old primary keys were broken up into two columns, one being useful. The column I need to use has some rows with the same values in them.
I am looking for some way in a SQL script to look for the duplicate rows and add "_X" to the data where X is a value incremented by 1 for each duplicate row found.
For example, 3 duplicate rows with "5443aa" would return "5443aa", "5443aa_1","5443aa_2".
I'm trying to merge two Access databases into one SQL server database. I have 3 tables that are all related with primary and foreign keys.
When I try to import my second set of 3 tables I get errors about the keys already existing in the database. Is there any way to force SQL server to assign new keys while preserving my existing relationships? Thanks!
I'm designing an app for stock keeping. In my DB, I have a field called "ItemSerialNo" and I made it unique(but not the table's primary key). On my front end, I have a text box for Item Serial No and a combo box loaded with the item brands and also a save button. I know that if I try to save a serial no already existing in my DB, the app won't allow me because of the unique property of the field named "ItemSerialNo". But I want to be able to save a serial no already existing in my DB but with a different brand name.
For example, I want to be able to save information like:
1. ITEM SERIAL NO = 12345 BRAND NAME = AA 2. ITEM SERIAL NO = 12345 BRAND NAME = BB.
We need to move duplicate data from this sheet to other table also having issue that sometime verifiedmemberID is null as well as verifiermember name is null and also having the values in BCP authorisationcode as well as FPoveridecode but transactionmode/bcpmode is 'n' and also having condition that transactionmode/bcpmode is 'y' but bcpauthorisationcode is blank.
I have heard from my client that they are facing duplicate data issue on one of the fact table.
Basically there is a view built on fact table and client access the data through the views.
There warehouse is loaded daily through SSIS packages. The duplicate records issue is only when the views are queried during the data loading process. The duplicates are gone when the data load is completed.

Hi, I want to know the different sources, mediums and ways using which the duplicate recoprds or adta can make an entry in our database tables. I found 4 ways for this from many articles on net that are as follows:
Duplicate data might arrive at your database via an interface to another system Data is loaded into table from other sources because during data loads, the integrity constraints are disabled Merging data from disparate systems Inheriting a poorly designed databaseBut is there any other ways also present????? Please tell me???
I have a table that contains more than 10,000 rows of duplicate data. The script below copies the data to a temp table then deletes from the original table. My problem is that after it runs, I now have 122 rows of triplicate data (but dups are gone). If I rerun the script, it doesn't see the triplicate data and returns 0 rows. I've use three different versions of delete dup row scripts with the same result. There are no triggers or constraints on the table, not even a primary key. What am I missing?-------------------------------------------------------------------

Hi i have the following stored procedure which should retrieve data, the problem is that when the user enters a name into the textbox and chooses an option from the dropdownlist it brings back duplicate data and data which should be appearing because the user has entered the exact name they are looking for into the textbox.
