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 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 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.
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 ?
In my database, I have a table "tbl_c_extract" that consists of 4 columns that look the following. I'm looking at a daily batch of around 4000 records, of which 150 are likely to be duplicates.
In the example above, I need to remove 2 of the entries, leaving only the one that with the maximum leave date. In this case, those without a leave date have the 2099 entry.
Using CTE works exactly as I want it to, however SQL Server Agent doesn't seem to like the use of CTE..
Code: WITH CTE (Proprietary_ID, LeaveDate, RN) AS ( SELECT Proprietary_ID, LeaveDate, ROW_NUMBER() OVER(PARTITION BY Proprietary_ID ORDER BY Proprietary_ID, LeaveDate) AS RN FROM tbl_c_extract ) DELETE FROM CTE WHERE RN > 1
I need to delete the duplicate rows from a table. How to do that in SQL server 7.0 ? If possible write an example, so that it will be much useful for me..
Hi, New to this Database and this forum as I am I would like to ask for a couple of prompts. My SQL2000 tables are ready and I need to schedule Daily upload of .txt files. These contain a rolling 7Days of Stats. Q1: How best to schedule the automiatic uploading of this data to the respective Tables in SQLServer.(Field names are identical), and Q2: How to schedule a Daily Deletion of those rows which are in the tables already (Each day 6 Days must be Deleted and 1 kept)
Hi , i am using sql server 2005. i have one table where i need to find records that have same citycode and hospitalcode and doctorcode then delete the record keeping only one record of them my problem is table structure have idendtity column which is unique. that is m table structure is something like
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?
int1 must have the value 1 int2 must have the value 1 int3 must have the value 0 and now we get to the difficult part - first character in the field [Cost No] have to be different from the letter 'B'. [Cost No] have the datatype varchar(20)
I expected the code to look something like this: DELETE Table1 FROM Table 1 WHERE ([Int1] = 1) AND ([Int2] = 1) AND ([Int3] = 0) AND ((LEFT([Cost No]), 1) <> 'B')
But I get this error message: The left function requires 2 arguments
What am I doing wrong and what should the right code look like?
i have 6 read only tables that every night all the data gets dumped and a new updated copy of the data is copied over. the tables range from 500,000 rows to almost 4 million. i have indexes set up on the fields i use to query against. my questions are 1.since i dump all the data every night and replace it, do i need to rebuild the indexes every night or is that done after the data is reentered? 2.i want to use a fill factor on the table since it is read only, but will dumping the data every night and reinputting it have adverse affects with a fill factor? 3.should i be shrinking the database or defragging it everynight cause of my data dumps and reloads?
How can I quickly delete thousands of rows in a table (SQL2000) according a query and without blowing up the log file? For instance executing the query: Delete from transactions WHERE transactiondatestamp < DATEADD (m,-4,GETDATE())
increases my log file to almost 6GB before job was done an normal size was re-obtained. In addition it took a long to time to get the job done. With the command truncate table I cannot use query unfortunately but this would be faster.
This SQL statement, though carefully written to delete only selected rows, deletes the entire A_Shift_Times table:
DELETE FROM A_Shift_Times WHERE EXISTS ( SELECT 1 FROM Users WHERE (A_Shift_Times.time_in >= CONVERT(DATETIME, '2000-05-29 00:00:00', 102)) AND ((Users.User_Password LIKE N'mrr%') OR (Users.User_Password LIKE N'work%')))
I export one table to Excel using Export Wizard. Second time I have used this creator I have checked option "Delete rows in destination table" because table already exists in Excel file.
During execution I get an error:
"Error 0xc002f210: Preparation SQL Task: Executing the query "DELETE FROM 'MyTable'" failed with following error: " and here is my translation from my language: "Deleting data from linked table is not supported by this version of ISAM"
I have also saved this package to a file and here is the full connection string to my Excel file:
Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:Documents and SettingsprzemekPulpitmyfile.xls;Extended Properties="EXCEL 8.0;HDR=YES";
Few days ago I have been using SQL2000 on the same machine and the same export was working properly.

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 300+GB. it holds 10 years of Data. I need to delete 5 years of data and put it to another server so I can have more space.
If I delete 5 years of data, Transaction log gets so huge and size of the database even gets bigger because of the .ldf file which even gets bigger! I think I can shrink the log file and the data file. Is this the best way to do it?
I have deleted nearly 30 million rows from a table. But however when I used the sp_spaceused command to calculate the data occupied by the table I don't see any difference in the data size of the table. In fact the data has increased to few MBs after the deletion, but not much.
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 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.
I want to delete duplicate row from a very big table. Actually this table is used by a SP, and it's a very important. Due to duplicate record entry it's falling. I use bellow method for discarding the dulicate record.
PLz tel me it's the most efficent way to this job or u have some other way
1. I drop the primary key
2. Then I let all the duplicate record came into the table
3. then I removed them by using Group by clause and setting rowcount(1 - group by count).
4. Put primary key back and update the statistics.
Code is
If Exists (select * from SYSINDEXES where name='PrimaryKey' and id=Object_id('AdjustmentTransactions')) DROP INDEX AdjustmentTransactions.PrimaryKey
Insert into AdjustmentTransactions (UrnABS, UrnBar, .................Description) Select a.UrnAbs, a.UrnBar, a.TxnUrn..................... a.Description from TxnProcess a where a.InsUpFlag = 'I' and a.Processed = 'N' and ASCII(b.TxnType) = 65
Set @row_count=0 Declare dup_cursor cursor for Select UrnBAR,TxnUrnBarPat,count(*) counts from AdjustmentTransactions group by UrnBAR,TxnUrnBarPat having count(*) > 1 Open dup_cursor Fetch next from dup_cursor into @VUrnBAR,@VTxnUrnBarPat,@count
While (@@Fetch_Status = 0) Begin Select @row_count=@count-1 Set rowcount @row_count Delete from AdjustmentTransactions where UrnBAR=@VUrnBAR and TxnUrnBarPat=@VTxnUrnBarPat Fetch next from dup_cursor into @VUrnBAR,@VTxnUrnBarPat,@count End Set rowcount 0 Close dup_cursor Deallocate dup_cursor If not Exists (select * from SYSINDEXES where name='PrimaryKey' and id=Object_id('AdjustmentTransactions')) CREATE UNIQUE INDEX [PrimaryKey] ON [dbo].[AdjustmentTransactions]([UrnBAR], [TxnUrnBarPat]) ON [PRIMARY] Update Statistics AdjustmentTransactions
