How do i remove duplicate records from a table with a single query without using cursors or anything like that.Sample :tempCol11221P.S The table has only one column
Hello friends, I have a one problem, i have a table in that some reocrds are duplicate.i want to find which records are duplicate. for exp. my table is as follows emp_id emp_name 1 aa 2 bb 3 cc 1 aa 3 cc 3 cc and i want the result is like emp_id emp_name 1 aa 1 aa 3 cc 3 cc 3 cc
I have a table that has duplicate records with the exception of the ID and I am trying to write a while loop that would go through the table, locate all duplicate records based on a field called LASTNAME.
I just discovered that all my records appear twice inside my table, inother words, they repeat on the row below. How can I delete all of theduplicates? I'm sure there must be a tidy line of sql to do that.Thanks,Bill
I uploaded some data about 2 or 3 times and it keep appending it to thetable.Now I want to keep only first duplicate and delete rest of.Suppose part number 123 has been added 3 times so I want to keep only 1record.Thanks
I loaded one table via SSIS and found that it contained many duplicate records (from the input source). I can create a SQL task to delete them, but I wonder if SSIS offers and task "out of the box" to delete dups?
Hello Frnds....Can anybody give the answer of this question as How to Delete duplicate records from Table ? I Know that with check option and also with Unique Constraint we can avoid to enter duplicate records in table but How to delete from table which does not have any constraints ?
any useful SQL Queries that might be used to identify lists of potential duplicate records in a table?
For example I have Client Database that includes a table dbo.Clients. This table contains various columns which could be used to identify possible duplicate records, such as Surname | Forenames | DateOfBirth | NINumber | PostalCode etc. . The data contained in these columns is not always exactly the same due to differences caused by user data entry; so some records may have missing data from some of the columns and there could be spelling differences too. Like the following examples:
1 | Smith | John Raymond | NULL | NI990946B | SW12 8TQ 2 | Smith | John | 06/03/1967 | NULL | SW12 8TQ 3 | Smith | Jon Raymond | 06/03/1967 | NI 99 09 46 B | SW12 8TQ
The problem is that whilst it is easy for a human being to review these 3 entries and conclude that they are most likely the same Client entered in to the database 3 times; I cannot find a reliable way of identifying them using a SQL Query.
I've considered using some sort of concatenation to a new column, minus white space and then using a "WHERE column_name LIKE pattern" query, but so far I can't get anything to work well enough. Fuzzy Logic maybe?
the results would produce a grid something like this for the example above:
ID | Surname | Forenames | DuplicateID | DupSurname | DupForenames 1 | Smith | John Raymond | 2 | Smith | John 1 | Smith | John Raymond | 3 | Smith | Jon Raymond 9 | Brown | Peter David | 343 | Brown | Pete D next batch of duplicates etc etc . . . .

Hi I am trying to retrive data from table store in .sdf database file but not able to do it. where i will use select * from xyz in project. I am developing it on desktop using vc++ 2005 in SQL server compact edition.
am using
hr = pICmdText->Execute(NULL, IID_NULL, param, NULL, NULL); It is not easy for me to see data of table from sdf file
Im using many source tables in a dataflow from which data has to be union in to a single table.While doing this i have to pull the table names in to the destination table.How to get the table names as column values?
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.
Yes, I know this subject has been exhausted, but I need help in locating the discussion which took place a few months ago. Sharon relayed to the group a piece of software (expensive) which would help in my particular situation. I grabbed a demo and have gotten the approval for purchase. Unfortunately, I don't have the thread with me at work.
The problem:
Number Fname Lname Age ID 123 John Franklin 43 1 123 Jane Franklin 40 2 123 Jeff Franklin 12 3 124 Jean Simmons 39 4 125 Gary Bender 37 5 126 Fred Johnson 29 6 126 Fred Johnson 39 7 127 Gene Simmons 47 8
The idea would be to get only unique records from the Number column. I don't care about which information I grab from the other columns, but I must have those fields included. If my resultant result set looked as follows, that would be fine. Or any other way, as long as all of the fields had information and there were only unique values in the Number field.
Number Fname Lname Age ID 123 Jeff Franklin 12 3 124 Jean Simmons 39 4 125 Gary Bender 37 5 126 Fred Johnson 39 7 127 Gene Simmons 47 8
If anyone remembers this discussion, mainly the date, I would really appreciate it.
I have two tables, one contains all work orders, the second contains records on work orders that are linked to customoer orders. I'm trying to create a query that will return specific fields from the table that contains orders in the linked order table, and only the work orders in the all order table that (work_order) do not exist in the linked order table (demand_supply_link). I have tried several queries and cannot get the results I desire. Here is the query I am currently trying.
SELECT DISTINCT WORK_ORDER.DESIRED_WANT_DATE as 'Want Date', DEMAND_SUPPLY_LINK.SUPPLY_BASE_ID as 'WO Id', WORK_ORDER.DESIRED_QTY as 'End Qty', DEMAND_SUPPLY_LINK.SUPPLY_PART_ID as 'Part Id', CUST_ORDER_LINE.CUSTOMER_PART_ID as 'Cust Part', OPERATION.RESOURCE_ID as Resource, PART.DESCRIPTION as Description, CUSTOMER.NAME as Name FROM ((((DEMAND_SUPPLY_LINK INNER JOIN CUST_ORDER_LINE ON DEMAND_SUPPLY_LINK.DEMAND_BASE_ID = CUST_ORDER_LINE.CUST_ORDER_ID) INNER JOIN WORK_ORDER ON DEMAND_SUPPLY_LINK.SUPPLY_BASE_ID = WORK_ORDER.BASE_ID) INNER JOIN OPERATION ON WORK_ORDER.BASE_ID = OPERATION.WORKORDER_BASE_ID) INNER JOIN PART ON WORK_ORDER.PART_ID = PART.ID) INNER JOIN (CUSTOMER INNER JOIN CUSTOMER_ORDER ON CUSTOMER.ID = CUSTOMER_ORDER.CUSTOMER_ID) ON CUST_ORDER_LINE.CUST_ORDER_ID = CUSTOMER_ORDER.ID WHERE WORK_ORDER.DESIRED_WANT_DATE Is Not Null AND OPERATION.RESOURCE_ID in ('ASSY','FAB 1','PLAY TRK') AND WORK_ORDER.STATUS='R'
UNION SELECT distinct work_order.desired_want_date as 'Want Date', work_order.BASE_id as 'WO Id', work_order.desired_qty as 'End Qty', work_order.part_id as 'Part Id', operation.resource_id as Resource, part.description as Description FROM WORK_ORDER INNER JOIN PART ON PART_ID=WORK_ORDER.PART_ID INNER JOIN OPERATION ON WORK_ORDER.BASE_ID=OPERATION.WORKORDER_BASE_ID WHERE WORK_ORDER.DESIRED_WANT_DATE IS NOT NULL AND OPERATION.RESOURCE_ID IN ('ASSY','FAB 1', 'PLAY TRK') AND WORK_ORDER.STATUS='R'
This is the error I receive: Server: Msg 205, Level 16, State 1, Line 1 All queries in an SQL statement containing a UNION operator must have an equal number of expressions in their target lists.
The all orders table (work_order) will not have the other fields to link to as there is no customer order linked to them.
Can someone tell me the best procedure when trying to find duplicate records within a table(s)?
I'm new using SQL server and I have been informed that there maybe some DUPS within unknown tables. I need to find these DUPS.
If someone can tell me how to perform this procedure I would apprciate it. And if you reply can also include examples that i could follow for my records.
Table1 has shop# and shop_id. Every shop# should have only one shop_ID. There has been a few data entry errors where a shop# has duplicate a shop_id. How to write a query for shop#s that have more than one shop_id?
Not so sure how simple this question is but here is what happened. I installed SQL Server 2005 on a new Win Server 2003. I exported the tables and their data from the old machine to the newly established database on the new machine.
It looks like all my records were duplicated. When I try to delete one of the duplicates it won't work because both rows are effected. I can't set my primary key now and if I try to create a new database with the primary key already set than the import fails.
Any one run into this before or know what's going on?
Hi,I have written a web application using dreamweaver MX, asp.net, and MSsql server 2005.The problem I am having occurs when I attempt to edit a record. I have setup a datagrid with freeform fields so that the user can click on edit, make the required changes within the data grid then click update. The data is then saved to the database. All this was created using dreameaver and most of the code was automatically generated for me.The problem is that, not everytime, but sometimes when I go to edit a record once I hit the update button to save the changes the record is duplicated 1 or more times. This doesnt happen everytime but when it does it duplicates the record between 1 and about 5 times. I have double checked everything but cannot find anything obvious that may be causing this issue. Does anyone have any suggestions as to what I should look for? Is this a coding error or something wrong with MSsql? Any ideas?Thanks in advance-Mitch
