Iam using sql server 2005. I want to delete the duplicate records from the table.Please specify a method which is very good at performance.
I have a table with one column, and i want to remove those records from the table which are duplicate i meant if i have a records rakesh in table two time then one records should be remove... my tables is like that
I have an SQL tables [Keys] that has various rows such as: [ID] [Name] [Path] [Customer] 1 Key1 Key1 InHouse 2 Key2 Key2 External 3 Key1 Key1 InHouse 4 Key1 Key1 InHouse 5 Key1 Key1 InHouse
Obviously IDs 1,3,4,5 are all exactly the same and I would like to be left with only: [ID] [Name] [Path] [Customer] 1 Key1 Key1 InHouse 2 Key2 Key2 External
I cannot create a new table/database or change the unique identifier (which is currently ID) either. I simply need an SQL script I can run to clean out the duplicates (I know how they got there and the issue has been fixed but the Database is still currently invalid due to all these duplicate entires).

I was wondering if anyone had a suggestion as to how to delete duplicate rows from a table. I have been doing this:
SELECT * INTO TempUsersNoRepeats FROM TempUsers2 UNION SELECT * FROM TempUsers3
This way I end up with a total of four tables (the fourth table being the original Users table) and I was hoping that there was a way that I could do this all within the the original Users table and not have to create the three TempUsers tables.
I am using SLQ Server 2008 R2. The database was designed by another company.
I have two tables: Client and Client_Location. In the Client table the pk is Client_ID. There is also a unique key: sys_Client_ID. Both the Client_ID and the sys_Client_ID fields exist as a foreign keys in the Client_Location table. However, the fields are not noted as unique in the Client_Location table. There are two fields in the Client_Location table that determine when the address was effective. They are from_dt and end_dt.
Multiple records have been loaded into the Client_Location table to track old as well as current addresses of clients.
I'm trying to run a report that will pull clients with a plan_id constraint from the Client table and join the Client_Location table to retrieve the current address of these clients.
My SQL is:
select distinct (a.client_id), a.cli_last AS Last_Name, a.cli_first AS First_Name, a.cli_middle AS Mid_Init, b.city AS City, b.county AS County, b.state AS State from ECBH.dbo.tbl_Client a inner join ECBH.dbo.tbl_Client_Location b on a.client_id = b.client_id inner join ECBH.dbo.tbl_client_insurance c on a.client_id = c.client_id inner join ECBH_TEST.dbo.tbl_GEF_County d on b.county = d.COUNTY_NAME where c.plan_id = 4 order by a.cli_last, a.cli_first
Because multiple records exist in the Client_Location table, the result set has duplicates. How can I pull only the results where the from_dt is most recent?
I have a temp table with the following columns and data
drop table #temp create table #temp (id int,DLR_ID int,KPI_ID int,Brnd_ID int) insert into #temp values (1,2343,34,2) insert into #temp values (2,2343,34,2) insert into #temp values (3,2343,34,2)
[Code]....
I use the rank function on that table and get the following results
select rank() over (order by DLR_ID,KPI_ID,BRND_ID ) Rown,* from #temp
I am interested only in Rown and Id columns. For each Rown number, I need to get the min(ID) in the second column and the duplicate ID should be in 3rd column as shown below.If i have 3 duplicate IDs , I should have 3 rows with 2nd column being the min(id) and 3rd column having one of the duplicate ids in ascending order(as shown in Rown=6)
I have a master table and i need to import the rows into the parent and child table.
Master table name is Flatfile_Inventory Parent Table name is INVENTORY Child Tables name are INVENTORY_AMOUNT,INVENTORY_DETAILS,INVENTORY_VEHICLE, Error details will be goes to LOG_INVENTORY_ERROR
I have 4 duplicate rows in the Flatfile_Inventory which i have already inserted in the Parent and child table.
Again when i run the query using stored procedure,its tells that all the 4 rows are duplicate and will move to the Log_Inventory_Error.
I need is if i have the duplicate rows in the flatfile_Inventory when i start inserting into the parent and child table the already inserted row have the unique ID i must identify it and delete that row in the both parent and chlid table.And latest row must get inserted into the Parent and child table from Flatfile_Inventory.
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.
Dear Gurus,I have table with following entriesTable name = CustomerName Weight------------ -----------Sanjeev 85Sanjeev 75Rajeev 80Rajeev 45Sandy 35Sandy 30Harry 15Harry 45I need a output as followName Weight------------ -----------Sanjeev 85Rajeev 80Sandy 30Harry 45ORName Weight------------ -----------Sanjeev 75Rajeev 45Sandy 35Harry 15i.e. only distinct Name should display with only one value of Weight.I tried with 'group by' on Name column but it shows me all rows.Could anyone help me for above.Thanking in Advance.RegardsSanjeevJoin Bytes!
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 used the following select statement to get duplicate records on Case_number column
select cases.distinct case_link, cases.case_number from cases group by case_link having case_number > 1
I got the error message that
"'cases.warrant_number' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause. AND cases.case_number' is invalid in the HAVING clause because it is not contained in either an aggregate function or the GROUP BY clause.
Any idea on a better statement to use. THANKS FOR YOUR HELP!
Hi, I have a table and this is what i did to get the desired result
Select A.col1,count(A.col1) from Tab1 group by col1 having count(A.Col1) > 1
i tried this - but it didnot worked - it returned col1 as blanks - Select A.col1,B.Col2,count(A.col1) from Tab1 A, Tab2 B where A.col1 = B.col1 group by A.col1 , b.col2 having count(A.Col1) > 1
As I was looking for all the rows that are apperaing more than once.
Now - The problem -
I have to join this table to another table Tab2 to get the other details. My Tab2 is a table from where I have to pull the Customer DEtails like name,address etc. How should I write this query? Any thinuhts? TIA
Hi. I'm a SQL Server newbie, very experienced with Access, developing an ASP.NET database editor web app. I query the database with a statement more or less in the following form:
SELECT organisation.OrgID, organisation.Name, organisation.whatever FROM services INNER JOIN servicegrouping ON services.serviceID=servicegrouping.serviceID INNER JOIN organisations ON servicegrouping.OrgID = organisations.OrgID WHERE services.service=x OR services.service=y
In other words, I have a database of organisations. The services offered by the organisations are in a separate table, and I only want to return organisations that offer services X or Y.
Okay, now if I did this in Access, this query would return just one record for each organisation that meets the condition, unless I was to include a field from the services table in the SELECT clause, in which case of course I would get one record for each organisation and unique service offered.
But in MS SQL, the query returns duplicate rows if there is more than service offered by the organisation that meets the WHERE condition (=x or =y). Why is this and what do I need to do to my SQL statement to ensure I only get unique rows?
I've a query which gets a set of data from multiple tables -
select * FROM A inner JOIN q ON (RIGHT(q.name,CHARINDEX('-',REVERSE(q.name))-1)= a.id) inner JOIN t ON (t.id = q.id) inner JOIN s ON (q.name = s.name ) inner join l on (s.name = l.name and t.name = l.name)
WHERE A.id = 764 and s.name = '764'
I get repeated # of rows for each id. I've some 136 rows for each q.id ( there are 6 q.ids and hence I get 816 rows instead of 136) These 136 rows are actually divided among thse q.ids as
Hello, I have a question, what does a statement look like that finds the duplicate rows and combines them, I have a table named PRODUCTS in it 3 columbs Cost, Stock, Part_number. I need to find all Part_numbers that dublicate, Combine the rows into 1 & combine (sum, add) their stock together is the new row & take an avarerage of their cost and use it as cost in the new row where they combine. Please help me, I am stalled. Looked all over the internet & could not find anything, I really need this for a project I can not finish. I have the following SQL statement: SELECT part_number, COUNT(part_number) AS NumOccurrences FROM Products GROUP BY Part_number HAVING COUNT(part_number) > 1
I have a csv file that I need to import daily into a SQL Server 2005 table. Much of the table contents could just be overwritten with the new csv file, however there are a set of Rows within the table that need to be appended to , rather than overwritten. There is no Primary Key in the csv file that can be used. I'm not sure this is the best approach, but what I have been trying to do, is append the entire csv file to the existing table, and then go back and delete the duplicates. When I run the Delete, it does delete the majority of the records, but leaves a couple hundred behind. The number left behind varies with each run, can't seem to identify a pattern here. Running the Delete a second time does clean up the rows left behind in the first execution of the Delete, and gives the result I want. Any thoughts as to why this needs to be run twice? Or is a better approach available? Here is my code - SELECT [Pkg ID], [Elm (s)], [Type Name (s)], [End Exec Date], [End Exec Time], dupcount=count(*) INTO temppkgactions FROM pkgactions GROUP BY [Pkg ID], [Elm (s)], [Type Name (s)], [End Exec Date], [End Exec Time]HAVING count(*) > 1
DELETE TOP (SELECT COUNT(*) -1 FROM dbo.temppkgactions WHERE dupcount > 1 ) FROM dbo.pkgactions DROP TABLE temppkgactions
I have a large table that consists of the columns zip, state, city, county. The primary key "zip" has duplicates but the rows are unique. How do I filter out only the duplicate zips. Randy Garland
Hi, I am encountering a problem. There are lots of duplicate rows in the cobol flat files (due to improper data entry and missing columns values )from where I am transforming data to sql 7. 0 tables using DTS. After transformation , can I some how mark the duplicate rows ? it is not for the purpose of eliminating them, but to enter the missing values and make all the rows complete and unique. I have the transformed table as a temporary table. Can I add a column like 'status' etc.. and have the column values marked '1' for the repeating rows etc.... Can anyone suggest 'any' possible way of implementing it ? Thanx Nisha
I have problem in deleting duplicate rows. I have a identity column in my table, if I try to use correlatted sub query with Delete command it gives error.
The other problem I have is I have a date column in my table and update that column with current date and time. If use a query to fetch a records on a particular day , it does not return any rows
select * from rates where ch_date >='02/11/99' and ch_date<='02/11/99'
If I use convert also there is some other problems. Is there any way to force date checkings to be done excluding time.
CAN ANYBODY REPLY FOLLOWING QUESTIONS. I WANT TO DELETE DUPLICATE ROWS IN MY TABLE WITHOUT USING TRANSACTION TABLE. AND ONE MORE QUESTION HOW TO GET YESTERDAY DATE BY USING ISQL WINDOW.
This is an imaginary problem while discussing ROWID in ORACLE.
Consider a table without primary key, unique key, uniuqe index. A row has inserted into the table many times. I want to delete all but one dulicated rows. With any 'where' clause all rows(duplicated) will be deleted. In ORACLE i can achieve this using ROWID as follows:
Delete from Table_name where < all column values > and ROWID <> ( Select max(rowid) from Table_name where < all column values > )
How can this be achieved in MS SQL Server 6.5 ?
According to Dr. Codd's Golden rules for RDBMS one is that One should be able to reach each data value in the database by using table name, row idenfication value and column name.
Does MS SQL Server 6.5 satisfy this requirement ?
Also How many of Dr. Codd's 13 Golden Rules for RDBMS does MS SQL Server 6.5 Satisfy? Which doesn't ?
Hi everyone, I'm migrating some information for a client at the moment. They had everything in Excel files and I'm getting them into SQL Server. There are some differences in the way I am storing data and the way they were storing data.
For each client they stored, they had something like Rel1 Rel2 Rel3 100 101 102
Now, what I have is a seperate row for each of Rel1, Rel2 and Rel3 so I would have 3 seperate rows with identical information except for Rel1. So I would have: Rel1 100 101 102
So one way I thought of doing it was inserting a new row specifying that the value for Rel2 should be stored in Rel1 and for the next row that the value for Rel3 should be stored in Rel1.
Now, I am able to do this but SQL Server inserts an extra row will the NULL value in Rel1. Does anyone know why this would be happening? I think what it is doing is finding a NULL value in Rel3 after creating the two extra rows and is inserting that NULL. So I think I need to check for NULLs and not allow it to create a new row if, say, Rel3 is NULL.
Any pointers are gladly welcome. (I know it's complicated )
Hello I am fairly new to SQL and having spent much time over the manual I decided to ask for help. So here's my deal.
I've got a query with 5 tables that I join together
Code:
SELECT * FROM Map INNER JOIN ThreatCategory INNER JOIN Threat ON ThreatCategory.threatCategoryID = Threat.threatCategoryID INNER JOIN Threat_Map ON Threat.threatID = Threat_Map.threatID ON Map.mapID = Threat_Map.mapID LEFT JOIN person on map.contentPersonID = person.personID WHERE (((DATEDIFF(dd, Map.dataAcquisitionDate, GETDATE()) > map.goodForDays) and (map.expired = '1')) or (map.expired = '3'))
The problem is the table Threat_Map is a many to many mapping between the Map table and the Threat table. Eg) A map can have more than one threat and a threat can have more than one map. I know this is not the best way to have a database set up but its out of my hands as to changing the database. What I need help with is this.
My application checks as to whether a certain field in the Map table is expired or out of date (as in the query). If so it gets some required information from the other tables using those joins. However, I don't want to get information for the same Map.mapID that's expired twice. I don't really care which ThreatID I get from the Threat_Map table I just need to get one of them to meet the objects standards. However, so far this seemingly simple task has eluded me. I'd like to do this in SQL. Is there perhaps a way to do this. If not I guess I'll just take care of it in the application.
