Duplicated Key.. How Can I Find This Key?
Jun 5, 2001
Hi, All
I have a problem with one table.
This table is corrupted so I drop the table and recreate the table..(Of course I export data) After that I try to put the primary key to new table but it won't allow me to do it. Error message says " There are duplicated key existed" Therefore I open up the EM and take a look at that table. There is key in that table but not Primary key..(also from the query analyzer using sp_help)
My question to U is how can I find this duplicated key and delete that info? I think somewhere in the system table contains this info but I don't know where:-(((
Thanks in advance..

Hello,
I have a table T1 with fields ID, F1, F2, F3, F4, F5, F6….
I need to find if there is duplicated rows based on F1, F2, F3 columns. If there is set F5=’minimum’ where ID is MIN(ID). So the smallest should be set as minimum. How can I do this in a stored procedure?

Hey,
I have a table that I truncate with an execute sql task, which uses the following statement:
truncate table dbo.tablename.
Afterwards I fill the table with data. Sometimes it gives an error that there are duplicated keys in the table, but it's truncated before the fill...
Is there anyone who has an idea on this matter?
Thanx

Hi,
I have just started developing in SQL Express in the last 2 months so still learning. The problem I€™m having with my stored procedure is that I get duplicate rows in my results. The row is a duplicate in terms of column 'Job No' as when the query runs in access only one instance of each 'Job No' is returned but when I recreate the query in SQL server I get a number of rows back for the same 'Job No'? How would I go about getting just 1 instance of each 'Job No' back? With column 'Days to Date' showing the total 'Days to Date' for each Job No. Please see Ms Access results if unsure of what I€™m asking.
A copy of the stored procedure is below and a sample of the out-put with Ms Access results at very bottom.
ALTER PROCEDURE [dbo].[sl_DaysDonePerJob] AS
SELECT CASE WHEN [Job No] IS NULL THEN '' ELSE [Job No] END AS [Job No], SUM([Actual Days]) AS [Days to Date], CONVERT(nvarchar(10),MIN(SessionDate),101) AS [Start Date],
CONVERT(nvarchar(10),MAX(SessionDate),101) AS [End Date],
MAX(CASE WHEN DATEPART(MM,SessionDate)=1 THEN 'Jan'
WHEN DATEPART(MM,SessionDate)=2 THEN 'Feb'
WHEN DATEPART(MM,SessionDate)=3 THEN 'Mar'
WHEN DATEPART(MM,SessionDate)=4 THEN 'Apr'
WHEN DATEPART(MM,SessionDate)=5 THEN 'May'
WHEN DATEPART(MM,SessionDate)=6 THEN 'Jun'
WHEN DATEPART(MM,SessionDate)=7 THEN 'Jul'
WHEN DATEPART(MM,SessionDate)=8 THEN 'Aug'
WHEN DATEPART(MM,SessionDate)=9 THEN 'Sep'
WHEN DATEPART(MM,SessionDate)=10 THEN 'Oct'
WHEN DATEPART(MM,SessionDate)=11 THEN 'Nov'
WHEN DATEPART(MM,SessionDate)=12 THEN 'Dec' END) AS 'End Month'
FROM Sessions
GROUP BY [Job No], Sessions.SessionDate
ORDER BY [Job No]
Results in SQL Server Express
'Job No' 'DaystoDate' 'Start Date' 'End Date' 'End Month'

I have many data in a table in which some rows are duplicated. How can I, for all duplicated rows, delete the extra rows and leave only one? You may assume checking one column is enough to tell if a row is duplicated.
Thanks

I have Account Table with the following columns.
ACCOUNT_NUMBER (p-key)
ROUTE_NUMBER
NAME
STATE
I have a unique account number for every record in the table (hence the p-key) however I have route numbers that are duplicated in the table. How do I find all records that have a ROUTE_NUMBER duplicated.
In other words, how do I query records where the route number occurs more than one time in the table.
I would like the following results....
ACCOUNT NUMBER ROUTE NUMBER NAME STATE
12345 1 WMT NY
48734 1 CBS TX
3945857 1 NBC LA
2847 2 FDX GA

Hello,
I've got a trouble with my query and left outer joins. I've got 2 tables, table A and B, both have the same record called ID. I used this query:
SELECT *
FROM A LEFT OUTER JOIN B ON A.ID = B.ID
This is OK and works fine, my trouble comes when i have a duplicated ID on both A and B. Instead of return 2 fields, it returns me 4.
Is there some way to force SQl server to return only the first founded on B, but the 2 duplicated IDs on the A table?
Thanks for all.

Hi,
Need to remove the duplicated rows from a table which has text/ntext/image type columns. The table does not have any PK/Unique column. (I accept its a bad data model). But currently changing the data model is not possible. Hence doing changes in application.
I couldn't do 'SELECT DISTINCT * from table', since the table has text columns. Though there is no PK constraint, If I know that col1 and col2 are join PKs in the table, Is that possible to select the distinct rows from such a table.
Please advise,
Thanks,
MiraJ

This one's kind of hard to explain, so I've opted to post a simplifiedversion of our view that prompted me to ask this question: Thequestion is re-asked after the view...create view MainView (PrimaryKeyID,SubTotal1,SubTotal2,GrandTotal)asselect t.PrimaryKeyID,sum(t1.Total),sum(t2.Total),sum(t1.Total) + sum(t2.Total)from SomeTable tjoin CalculationTable t1 on ...join AnotherCalculationTable t2 on ...Notice in the 3rd column called "GrandTotal" how it calls the function"sum" two more times. Common sense tells me that this is notnecessary. in our case it's orders of magnitude worse... Is the queryoptimizer smart enough to only call these sums once per row in"SomeTable"? Common sense tells me that if we were to break the viewsapart into two views it would avoid this ineffeciency:create view InnerView (PrimaryKeyID,SubTotal1,SubTotal2)asselect t.PrimaryKeyID,sum(t1.Total),sum(t2.Total)from SomeTable tjoin CalculationTable t1 on ...join AnotherCalculationTable t2 on ...create view OuterView (PrimaryKeyID,SubTotal1,SutTotal2,GrandTotal)asselect iv.PrimaryKeyID,iv.Total1,iv.Total2,iv.Total1 + iv.Total2from InnerViewNotice how it appears that we've tricked the optimizer into thinkingthere are less operations. So my question is how does views handlethis situation? Does the optimizer treat both version the same? Or isone faster than the other? Or is there another, faster way? Doesadding levels of views slow down things, or are views simply likemacros and get removed when compiled (I think I've read the latter istrue actually)Thanks,Dave

I am getting this exception in RC1:
SqlCException: Duplicated parameter names are not allowed. [ Parameter name = @SOLUTIONID ]
With the following statement:
SELECT [VERSIONID], [SOLUTIONID], [BASEVERSIONID], [VERSIONNUMBER], [NAME], [DESCRIPTION], [CREATEDATE], [UPDATEDATE], [VERSIONCLOSED] FROM VERSIONS WHERE SOLUTIONID = @SOLUTIONID AND VERSIONCLOSED = 1 AND VERSIONID IN (SELECT MAX(VERSIONID)
FROM VERSIONS WHERE SOLUTIONID = @SOLUTIONID);
Besides the obvious of adding a new parameter with the same value and a different name - are there any plans to fix this?
Another area where SQLCE seems deficient is non-support of SCOPE_IDENTITY(), which although not important for CE itself is very important for TSQL compatibility with SQL Server - where obviously @@IDENTITY won't cut it.
A related problem to this is that SQL CE doesn't support batch statements - which sadly destroys the useful pattern of inserting a record with an INSERT and doing an identity SELECT in the same batch.

i this case the attributes that are equal in the table are account and description
how can i query them doing a select that returns only the attributes with the same value?

I have three FileStreams (FS1 on F drive, FS2 on H drive, FS3 on E drive) belonging to the same FileStream group of one particular database (DB) which is in Simple recovery mode in the SQL Server 2012.
FS1 contains huge number of files due to which F drive is completely full.
So, I am trying to move some of the extra files from one FileStream (FS1 on F drive) to another FileStreams (FS2 on H drive and FS3 on E drive) using command:
dbcc shrinkfile('FS1', emptyfile)
Then, I take the Full and Differential backup of the database and issue the CheckPoint and try to delete the already duplicated files from the Filestream FS1 to get some space in the F drive using command:
sp_filestream_force_garbage_collection @dbname = 'DB' , @filename = 'FS1'
But still no files get deleted and I receive the output as such:
file_name num_collected_items num_marked_for_collection_items num_unprocessed_items last_collected_lsn
DB_FS1 0 0 0 25000001749500000
how to delete these already duplicated files.

Hi.I have a table (websitehits) which holds statistics about websites.This table has a date field (datecounted). What I need is to create aquery which returns a list of dates between two date ranges (say ayear ago from today and a year from now) which only shows dates thathaven't been used in the websitehits table for a given website.For example if my table contains something like:Website Datecounted HitsSite101/01/046000Site101/02/046500Site101/03/046250Site201/03/041000Site201/04/041200Site201/05/041500So if query for ‘site1' then I'd get a list of all dates between30/11/03 to 30/11/05 with the exception of the dates 01/01/04,01/02/04 and 01/03/04.So far I've tried to do this using another table named calendar whichcontains a very long list of dates and to use this to produce the list– but I'm not getting very far.By the way I'm using sql server, an I need this query to generate alist for an asp page - so I need to pass the website name as aparameter so I guess I need to make this query as a stored procedure.Does anyone know how this can be done?

I've a matrix report with two row groups. One of the row groups has been used to do alternate coloring in report rows. The issue is that the header text that I've provided for the row group repeats twice. Another interesting point to note here would be this doesn't happen in the report preview but only when the report is displayed through a report viewer in an ASP.Net application. I can guess that it must have got something to do with the invisible row group but can't get my head around on how to avoid it?
The report currently looks something like below:
Month 2007 2008
Month Total Ave % Total Ave %
-----------------------------------------------------------------------
January 12 6 1.5......................etc etc.
I want the text "Month" to come only once. Thanks.
