Duplicate Data
Hello all,
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.
Can anyone help?
Thanks

Delete Rows With Duplicate Column Data But Unique Row Data
Hello, 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, Kerry

Duplicate Data?
I am new to SQL server 6.5. 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. DAvid Spaisman would be greatly appreciated. THanks. David Spaisman

How To Sum Data That Is A Duplicate
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

Duplicate (almost) Data
Ok, I'm fairly new to SQL so sorry if this is obvious. I have two Databases on the same SQL server, and I want to duplicate a table from one in the other, but with two requirements. 1. Ideally I would like any changes in the data in the first to be automatically updated in the second. 2. I need to change the data type of the primary key from Bigint to Float in the process. I tried a DTS package, which created the second table fine, the problem I have is making a dynamic link. I have also tried a CREATE VIEW with both CAST and CONVERT in the first Db but to no avail. (This is all so I can link to an Access front end and it can't handle Bigint in the PK, I just get #Deleted in every cell.) Any thought? It seems as though it should be easy but I can't figure it.

Inserting Duplicate Data
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!

Filtering On Duplicate Data
Hello, I have a dataset which I would like to remove data from, but I can't seem to find out how to do this. The dataset contains the following columns: SCode, NIn, SIn, AIn, NOut, SOut, AOut and TagNumber. I would like to remove data from the dataset when the following occurs: ("SC123", "NIn123", "s-in-323", "a-in-342", "NOut43", "s-out-231", "a-out-45", "tagnumber12") ("SC123", "NIn123", "s-in-xyz", "a-in-xws", NULL, NULL, NULL, "tagnumber12") This is when NIn occurs with the same value more than once, and I would like to remove (or ignore, filter) the row when NOut, SOut and AOut are null. I am new to SSIS and can't see how I could do this (although I'm sure it's possible). If anyone could show me how I would appreciate it. Thanks.

Displaying Duplicate Data
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? Highlighted Blue - just there to fill in the front page with data (not wanted) Highlighted Green - doesn't work, but was my first attempt Code: public function ShowQuotes Dim objConn Dim objADORS Dim strSQL Dim row Set objConn = Server.CreateObject("ADODB.Connection") objConn.ConnectionString = strConn objConn.Open Set objADORS = CreateObject("ADODB.RecordSet") strSQL = "Select top 50 " strSQL = strSQL & " cv.config_version_id as cvid, cv.configuration_id as cid, cv.version_number as cnum" strSQL = strSQL & ", cv.status as cstat, cv.total_price as cprice, cv.modification_date as cmod, cv.version_description as cvrem" strSQL = strSQL & ", c.remarks as qrem" strSQL = strSQL & ", p.prod_description as pdesc, p.version as pvers, p.status as pstat" strSQL = strSQL & ", cust.customer_name as custname" strSQL = strSQL & ", us.user_nt_login as modname" strSQL = strSQL & ", us.user_name as usname" ' strSQL = strSQL & ", cv.user_id as modname" strSQL = strSQL & " from tbl_config_version as cv, tbl_configuration as c, tbl_product as p, tbl_user as us, tbl_customer as cust" strSQL = strSQL & strWhere 'SETS RESULTS TO BE UNIQUE strSQL = strSQL & " and us.user_id = c.user_id" strSQL = strSQL & " and cv.configuration_id = c.configuration_id" strSQL = strSQL & " and c.product_id = p.product_id" strSQL = strSQL & " and c.customer_id = cust.customer_id" strSQL = strSQL & strOrderBy & ";" Image: www.mcdcs.co.uk/TT.jpg

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

Renaming Duplicate Row Data To Be Unique?
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". Any ideas? --MartinZ

Since the real table have primary keys so it goes failed when there're duplicate rows from temp table. I let the temp table has no primary key. If I had to check the temp table for duplicate rows it would be using cursor through the data and the package will get slow. Is there task in SSIS to identify the duplicate data and eliminate it without using cursor ? Thanks in advance, Best regards, Hery

Duplicate Data Entry When Using The ASP.NET Web Site Administration Tool For Logins
Hello All, I am using the Web Site Administration Tool with the ASP.NET login controls to create/manage user logins & roles for my site.

The entry is doubled up in the database. This is not a problem when logging on....however, when it comes to deleting a user it will only take one of the entries out and leave the duplicate in there. So if the administrator has deleted a user from the app and then tried to create another one with the same UserName (Which whomever is well within his/her rights to be able to do), they cannot because the entry which has "stay behind" in the database conflicts with the entry. Any help on this matter would be greatly apprieciated. If any more info on this matter is required please ask (It was quite hard to try and explain this :-)

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 A01 7680 12345 C01 20 A01 7680 54321 G10 1032 E15 1163 54321 G10 1032 F20 523 54321 G10 1032 H30 750 98765 Z20 7000 Z20 8500 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 B01 6 B01 0 12345 C01 20 C01 0 54321 G10 1032 E15 1163 54321 F20 0 F20 523 54321 H30 0 H30 750 98765 Z20 7000 Z20 8500 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?

Dynamiclly Remove Duplicate Rows From Results Table Based On Column Data?
I have a results table that was created from many different sources in SSIS. I have done calculations and created derived columns in it. I am trying to figure out if there is a way to remove duplicate rows from this table without first writing it to a temp sql table and then parsing through it to remove them. each row has a like key in a column - I would like to remove like rows keeping specific columns in the resulting row based on the data in this key field. Ideas? Thanks, Ad.

Duplicate Key Ignored !!!
Hi guys, i have the following tables: Table1: [PKID] WITH INDEX "IGNORE DUPLICATE KEY" Table2: [FKID] and i have the following SQL statement: insert into Table1 select distinct FKID from Table2 where FKID not in (select PKID from Table1) The above SQL statement is in a DTS package which raises "Duplicate key ignored" error... i can't see how that can happen since i am already checking the key if it already exists. .. Please help !!! TNT :s

Duplicate Row
How can I compare numerous rows in the same table that have the same fname, lname and access_id but different identity values (and other columns) and then keep only the one row which is the most current based on a date col? This seems so easy, but today I just can't come up with it. Do I have to use a cursor of some kind? Troy

Duplicate Row's
I'm currently working on a Game DB, To where i can set Primary Key's and such, otherwise the Emu reads it wrong. The current table i am working on, has duplicate row's of every row. (3600 rows instead of 1800) and the duplicates have the same ID as the original row. How would i go about Deleting the Duplicate rows without harming the original? (Sql 2005) Regards Vision

Duplicate Key Ignored
I have a stored procedure that inserts records into a table with a Unique Clustered Index with ignore_Dup_Key ON. I can run the stored procedure fine, and get the message that duplicate keys were ignored, and I have the unique data that I want. When I try to execute this in a DTS package, it stops the package execution because an error message was returned. I have tried setting the fail on errors to OFF, but this has no effect. I found the bug notification that says this was corrected with service pack 1, and have now updgraded all the way to service pack 4, and still get the issue. I tried adding the select statement as described as a work-around in the bug, and still can't get it past the DTS. I have verified the service pack, re-booted, etc..... I am trying this in MSDE 2000a. Thoughts or comments? Thanks!
