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 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 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?
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 student table where duplicate student exist by name with there fathers name and mothers name. I need to search those duplicate records. I do not need ti count them but If there is 5 same student with name then the query will show 5 name then I will delete individually. Below I am trying to show the scenario.
Student_name _____________ Rocky Albert Rocky Williams Albert Robert
The query will show
Student_name ______________ Rocky Rocky Albert Albert

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
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 need a sql statement to delete duplicate records.
I have a college table with all colleges in the nation. I noticed that all of the colleges were listed twice. How do I delete all of the duplicate records.
Here is my table. Colleges ------------------- schoolID - smallint NOT NULL, schoolName - varchar(60) NULL
Can someone help me out with the sql statement??? I'm running SQL Server 6.5.
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 ?
Hi All, I am having one table named MyTable and this table contains only one column MyCol. Now i m having 10 records in it and all the records are duplicate ie value is 7 for all 10 records.
It is something like this,
MyCol 7 7 7 7 7 7 7 7 7 7
Now i m trying to delete 10th record or any record then it gives me error "Key column information is insufficient or incorrect. Too many rows were affected by update."
What should i do if i want only 4 records insted 10 records in my table? How do i delete the 6 records from table?
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..
Rajarajan writes "Kindly don't ignore this as regular case. This is peculiar. I need to delete one of duplicate records only if they occurs consecutively. eg.
1. 232 2. 232 3. 345 4. 567 5. 232
Here only the first record has to be delete. Kindly help me out.
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 to delete the master table data without deleting the child table records,is there any solution for this, parent table has relation with the child table. regards vinod.t.v
I managed to find the 'Deleting Duplicate Records' from SQLTeam.com (thanks, by the way!!).. I managed to modify it for one of my tables (one of 14).
-- Add a new column
Alter table dbo.tblMyDocsSize add NewPK int NULL go
-- populate the new Primary Key declare @intCounter int set @intCounter = 0 update dbo.tblMyDocsSize SET @intCounter = NewPK = @intCounter + 1
-- ID the records to delete and get one primary key value also -- We'll delete all but this primary key select strComputer, strATUUser, RecCount=count(*), PktoKeep = max(NewPK) into #dupes from dbo.tblMyDocsSize group by strComputer, strATUUser having count(*) > 1 order by count(*) desc, strComputer, strATUUser
-- delete dupes except one Primary key for each dup record deletedbo.tblMyDocsSize fromdbo.tblMyDocsSize a join #dupes d ond.strComputer = a.strComputer andd.strATUUser = a.strATUUser wherea.NewPK not in (select PKtoKeep from #dupes)

Now that I've got that figured out, I need to write the same thing to fix the other 13 tables (with different column info)- and I'll need to run this daily.
Basically I've put together some vbscript that gathers inventory data and drops it into an MSDE db (sorry - goin for 'free' stuff right now). Problem is it has to run daily so that I'm sure to capture computers that turned on at different times etc which ever-increases my database 'till I bounce off the 2GB limit of MSDE.
So the question is, what would be the best way to do this? Can I put the code into a stored procedure that I can execute each day?
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)
I have three tables 1. membership table(aspnet_membership table) 2. User Contacts table 3. Address table These three table have relation ship with one another through a UserId field. How will you set up cascaded delete on these tables, Like if I delete a user in the membership table I want the related records in the other tables to be deleted as well. Cascaded delete is it something done through code, or is it definde when the tables are created. Please advice.
Hey Guys,I have Performance Monitor running and storing the network usage to my MsSQL database, and this is done a few times a minute. I have a page that then shows show much of my bandwidth is being used. As you can gather, the database quickly starts filling up with hundrreds of records so I could do with a script that delete these records. I cant simply delete all records because that would cause my webpage to fail so I need a way to delete all records apart from the latest one. Wondering if anyone would know how I could do this?
I have a form that depending on the outcome, will either add, update or delete a record.
1) If there IS NO record of "this" and "that" and Request("x") <> "" it will add a new record.
2) If there IS a record for "this" and "that" and Request("x") <> "" it will update column 1,2,3 or 4.
3) If there is a record for "this" and "that" and Request("x") = "" it will delete the record.
My problem is if there is a value in request("1") it works fine, but if there is no value in ("1") and there is a value in 2, 3, or 4 it will delete the record.
If request("1") <> "" OR request("2") <> "" OR request("3") <> "" OR request("4") <> "" Then
sSQL = "SELECT * FROM some_column WHERE this = '" & request("this) & "' and that = '" & request("that) & "'" oRS.Open sSQL,oConn,adOpenKeySet,adLockOptimistic If oRS.EOF Then oRS.Addnew oRS.Fields("this") = request("this") ors.Fields("that") = request("that") Else ors.Movefirst End If oRS.fields("1") = request("1") oRS.fields("2") = request("2") oRS.fields("3") = request("3") oRS.fields("4") = request("4") oRS.Update oRS.Close
Else
sSQL = "Delete from some_table Where this = '" & '" & request("this) & "' & "' AND that = '" & '" & request("that) & "' & "'" objCmd.ActiveConnection = oConn objCmd.CommandType = adCmdText objCmd.CommandText = sSQL objCmd.Execute
Hi All,I am using Microsoft SQL Enterprise Manager version 8.0 and havecreated a view from a combination of 4 different tables. I would liketo be able to go into sql and open the view and select a row anddelete that row however this seem impossible right now. I am not sureif it's possible to delete a row from a view?? Or could it be thatthese tables are all interconnected and in order to delete a recordthat is joined to one or more of the tables it has to be deleted atthe top level of the join heirarchy etc etc. (do you understand what imean?) Can this be done??Thanks in advance,Erin

I've noticed that after the first record from a ResultSet is deleted, HasRows property throws an exception like "The current row was deleted." Method ReadFirst() throws similar exception as well.
More details:
1. Create a ResultSet: ExecuteResultSet(ResultSetOptions.Updatable | ResultSetOptions.Scrollable | ResultSetOptions.Sensitive)
2. Let's say, there is no records in the resultset. Insert two new ones. Then call: ReadAbsolute(0); Delete(); HasRows; and the exception is thrown.
3. Then you can call ReadFirst() or Read with the same result.
4. Now call ReadAbsolute(0). It returns true. Call HasRows, ReadFirst() or Read() and you will get the exception each time.
I tried to explain this with the fact that Delete() doesn't change the current position of the ResultSet. But I don't see why that would mess the HasRows property or why after ReadAbsolute(0) retuns true, HasRows or ReadFirst() doesn't work.

I am using the tables created by the aspnet_regsql.exe tool for security. Basically, I need to ensure that an account named Administrator is never deleted. I also have a role named administrator, and I need to make sure that Administrator is never removed from the administrator role.Can I create a trigger to ensure that the Administrator is never deleted and that the Administrator is never removed from the Administrator role? I know it will probably be two separate triggers: one on the aspnet_users table and one on the aspnet_usersinroles table.Thanks a lot for the help!
