Feb 12, 2008Hi
I have a data in one table like below.

---------- ------------ ----------------------
CNE TN-Town News 12/19/2007 12:00:00 AM

What i have to do is if there are multiple records for one product in any day, then i need to remove all those records. In this case i am getting two records for the PRODUCT 'TN-Town News' and for INSERTDATE = 12/19/2007 . So i need to remove these two records from the table.
How to do that?. Can anybody help me?

Transact SQL :: Remove Duplicate Records But Keep At Least 1 Record
Dec 3, 2010I have a table that "Geography" that has the following columns: city, state, zip
There are tons of duplicate cities in this table. I ran this query and it shows me the number of occurrences of each city. I want to delete all the duplicates except for 1. I don't want to do this manually as there are a lot of records.
What would the SQL look like to delete the duplicate records but keep at least one?
Transact SQL :: How To Remove Duplicate Records Based On Date Column
Jul 28, 2015I have a requirement where i want to delete the records based on the Date column. I have table which contain the columns like machinename ,lasthardwarescandate
I want to delete the records based on the max(Lasthardwarescandate) i.e. latest one, column where the machine name is duplicate menace it repeats. So how would i remove the duplicate machine names based on the Lasthardwarescandate column(There are multiple entries for the Lasthardwarescandate so i want to fetch the latest date column).
Note: Duplication should be removed based on “Last Hardware Scan” date.
Only latest date should be considered from multiple records for the same system. "

Remove Duplicate Entries
May 8, 2008
I am a newb at ms sql and was hoping someone could help me
eliminate duplicate PRODUCT.PRODUCT from this statement. I have tried using DISTINCT with the same results.The ProductImage table is causing this because
the duplicates are from the PRODUCT.PRODUCT that have more than 1 image.
If anyone could rewrite this statement so I can learn from this, it would
be most appreciated!
Thank you for your time

Remove Duplicate Data
Dec 16, 2004I have a query that for one reason or another produces duplicate information in the result set. I have tried using DISTINCT and GROUP BY to remove the duplicates but because of the nature of the data I cannot get this to work, here is an example fo the data I am working with
ID Name Add1 Add2
1 Matt 16 Nowhere St Glasgow
1 Matt 16 Nowhere St Glasgow, Scotland
2 Jim 23 Blue St G65 TX
3 Bill 45 Red St
3 Bill 45 red St London
The problem is that a user can have one or more addresses!! I would like to be able to remove the duplicates by keeping the first duplicate ID that appears and getting rid of the second one. Any ideas?
Cheers

Sep 5, 2007I have a table containing over 100,000 email addresses. This email table gets duplicates in it, and our customers don't want a second (or third or fourth) copy of our news letter. To prevent this, we run the following SQL to kill the duplicates:
Code Snippet
DELETE FROM _email WHERE _email.eid IN
(
SELECT tbl1.eid FROM _email AS tbl1 WHERE Exists
(
SELECT emailaddress, Count(eid) FROM _email WHERE _email.emailaddress = tbl1.emailaddress GROUP BY _email.emailaddress HAVING Count(_email.eid) > 1
)
)
AND _email.eid NOT IN
(
SELECT Min(eid) FROM _email AS tbl1 WHERE Exists
(
SELECT emailaddress, Count(eid) FROM _email WHERE _email.emailaddress = tbl1.emailaddress GROUP BY _email.emailaddress HAVING Count(_email.eid) > 1
)
GROUP BY emailaddress
);
This query takes about 2hrs to run which is really hurting our server preformance. Is there any way to do this faster?

As you can see, Joe Smith has two rows, but only one of the rows is complete. I would like to delete only the row that has a NULL value in the phone and area code for Joe Smith. There are a few thousand rows that are like this. They have duplicates all but the area code and phone number.I am used to using a CTE to remove duplicates, but I am a little lost on this one. The things that I have tried, have not worked exactly as I planned.

Filtering/Grouping To Remove Duplicate Values...
Oct 18, 2001There's some SQL below (T-SQL) & I'm wanting to have this result set
grouped by Venue_ID in order to remove rows where there are duplicate values contained in just one column.
The columns BCOM_ID contain unique values, but Venue_ID can have duplicate
values. I only want to get rows for one instance of the Venue_ID (per
BCOM_ID) - doesn't matter which instance but basically, no duplicates.
Oh yes, one of the columns is a Bit column.
Any ideas would be welcome & appreciated!
Many thanks,

Remove Outlying Records...

Is there some Transformation or other method to remove outlying records based on an attribute during a Data Flow task?
I have a list of Organizations complete with a list of Products they have bought. I am going to do some data mining / profiling off of this data but first I need to get rid of the top 25% and bottom 25% quantity records by Product. I've looked at Percentage / Row Sampling but they are too simple.
How would this be done in SSIS?

Dynamically Import Textfiles
Dec 27, 2007
Hi all,
RE: Dynamically import textfiles:
I have a C# assembly that scans textfiles in a certain directory residing on the same server as the SQL2005 database server.
The names and directory are retrieved from a configurationtable on the SQLServer.
These textfiles have a header with column information.
The problem is that these headers can change and as a result the table in which to import this data no longer reflects the columnlayout of the header in the textfiles.
I would rather not use xp_cmdshell or bcp utility and would like to create a package that dynamically sets the input and output columns while the rest of the package remains unchanged.
At the moment whenever the header of the textfile has changed the assembly I created drops and recreates an importtable for the textfile. All this runs without a problem.
But if I then import the textfile with the dataflow-object in the existing package I have to reset the columns in the metadata object to reflect the changed columns.
This is easily done by pressing the reset columns button on the design surface in BIDS, but I would like to do this automatically (programmatically).
So what I would like is to load a package (=no problem) and then reset the columns of the textfile source and table-destination in code. The samples I found on the web seem rather obscure to me and I am not sure which way is the preferred way.
Can anyone give me an example of loading a package and then resetting the columns (VS_NEEDSNEWMETADATA ReinitializeMetaData ?) of a flatfile-datasource and a SQLServer destination
in code (C#)?
Any help appreciated
Greetings,
Francis

View 6 Replies View RelatedHow To Remove Blank Spaces In Records??
Jun 23, 2005We imported approximately 2.9 million records from our mainframe server
into our SQL Server but have run into a problem. The data in a
few of the fields contains both leading and trailing spaces. An
example of the data would be like this, using periods to represent
spaces:
What we have:
..1A02938.....
What we need:
1A02938 (no spaces)
Is there some sort of algorithm I can run on the data to remove
those spaces? The problem is coming up when trying to perform a
SELECT query. We try something like:
SELECT * FROM PCPIPT0 WHERE PANO20 = "1A02938" but we get zero
results because of the spaces in the database. The datatype of
the filed is char(20) because we need some flexibility on the size of
the data stored.
Any assistance would be greatly appreciated.
Remove And Archive Records Into Another Table
Mar 5, 2008Hi,
I currently have one table that lists all projects and tasks within the organisation. One of the table fields is the task status, open or closed. I would like to be able to have a process by which the tasks that are completed are removed from the table and placed into another (archive) table. The same records then being removed from the original table. which then only contains the incomplete tasks. This process could be run at given times during the day or at the point when the status of a task is changed from open to closed, either way each time the process is run it would need to append the rows removed into the archive table. Anyone any ideas on the best way to do this?.
Thanks
