hello everyone,
how to prevent putting same value into the column in the sqldatabase?
while inserting value into the table from asp.net page dynamically,i dont want user to insert same
data again and again.
is there anyway i can make check the column in the database to look for the duplication value.
if not then only i want to make it insert.
thanks.

I have a table in which a non-primary key column has a unique index on it.
If I am inserting a record into this table with a duplicate column value for the indexed column, then what will be the error number of the error in above scenario? OR How could I find this out?
I have one table with two columns, GUID and PID and another table with three columns, GUID, LastName, and FirstName. For each unique PID, I need to find the PID's that have more than one GUID and then match that with their respective FirstName and LastName from the other table.
Table1
GUID PID
GUID1 PID1
GUID1 PID1
GUID1 PID1
GUID2 PID1
GUID3 PID2
GUID3 PID2
GUID3 PID2
Table2
GUID LastName FirstName
GUID1 Mulder Fox
GUID2 Scully Dana
GUID3 Skinner Walter
So I'm looking for a result like:
PID1 GUID 1 Mulder Fox
----- GUID 2 Scully Dana
Hi all,
I have one table in which one column contains duplicate values. My question is how i can use T-SQL so that i can retrive values for all columns in the table which are distinct and retriving the single value from column which contains duplicate values.
(I know distinct)
Thanks in advance.
Minesh.
I have column A,B and C. I need a query to find the duplicates among these column.
Thanks,

I'm have a problem with trying to generate a view that has a count of duplicates values per column in a table.
example I have a table with the following structure:
CREATE TABLE [dbo].[TestDpln](
[CountryCode] [smallint] NOT NULL DEFAULT ((0)),
[NPA] [smallint] NOT NULL DEFAULT ((0)),
[NXX] [smallint] NOT NULL DEFAULT ((0)),
[XXXX] [smallint] NOT NULL DEFAULT ((0)),
[3-Digit] [nvarchar](3) COLLATE SQL_Latin1_General_CP1_CI_AS NULL,
[4-Digit] [nvarchar](4) COLLATE SQL_Latin1_General_CP1_CI_AS NULL,
[SiteIdx] [int] NULL DEFAULT ((0)),
CONSTRAINT [TestDpln$PrimaryKey] PRIMARY KEY NONCLUSTERED
(
[CountryCode] ASC,
[NPA] ASC,
[NXX] ASC,
[XXXX] ASC
)WITH (PAD_INDEX = OFF, IGNORE_DUP_KEY = OFF) ON [PRIMARY]
) ON [PRIMARY]
the data loaded looks like this
INSERT INTO dbo.TestDpln VALUES('1','312','555','1212','212','1212','1')
INSERT INTO dbo.TestDpln VALUES('1','312','555','1213','213','1213','1')
INSERT INTO dbo.TestDpln VALUES('1','525','555','2212','212','2212','2')
INSERT INTO dbo.TestDpln VALUES('1','525','555','2213','213','2213','2')
the results I need are
SiteIdx 3 Digit Count 4 Digit Count
------- ------------- -------------
1 2 0
2 2 0
I've tried various queries the closest being:
SELECT DISTINCT SiteIdx, COUNT(*) as "3-Digit Count"
FROM dbo.TestDpln
GROUP BY SiteIdx, "3-Digit"
HAVING COUNT(*) > 1
but it only shows one column and one site I'm not sure how to get the '4 Digit Count' column to show up and the rest of the sites. below are the results I get so far.
SiteIdx 3 Digit Count
------- -------------
1 2
any help would be great.
Thanks

We have a table with 1 million rows with duplicates in a column which allows nulls.Can we enforce uniqueness for only future inserts by anyway(ignoring the old ones)?
Thanks!
I am trying to get people from my table that have closed accounts. However, in my table many people have more than one account. They will have multiple closed accounts and some active accounts. I need to get the people with only closed accounts.
Values in the table
Code:
name surname status Closed Number
----------- --------- ----------- ------------- ----------------------------
Jeff Burns closed 2012/01/01 142
Tina Drewmor closed 2008/05/20 546
Jeff Burns active 1900/01/01 354
Kyle Higgin active 1900/01/01 851
Tina Drewmor closed 2009/04/14 154
The query I am using so far is:
Code:
select
d.name,
d.surname,
s.status,
s.closed,
s.number
from
d d inner join s s on d.number = s.number
where
s.status = 'closed'
What I need to see in the results
Code:
name surname status Closed Number
----------- --------- ----------- ------------ -----------------------------

E 10 Test1
F 11 Test2
Result
Col1 Col2 Col3 Count

Hi there, newbie here.
I'm building a web application that allows for tagging of items, using ASP.NET 2.0, C# and SQL Server.
I have my USERS, ITEMS and TAGS separated out into three tables, with an intersection table to connect them.
Imagine a user has found an item they are interested in and is about to tag it. They type their tag into a textbox and hit Enter.
Here's what I want to do:
I want to search the TagText column in my TAGS table, to see if the chosen tag is already in the table. If it is, the existing entry will be used in the new relationship the user is creating. Thus I avoid inserting a duplicate value in this column and save space. If the value is not already in the column, a new entry will be created.
Here's where I'm up to:
I can type a tag into a textbox and then feed it to a query, which returns any matches to a GridView control.
Now I'm stuck... I imagine I have to use "if else" scenario, but I'm unsure of the code I'll have to use. I also think that maybe ADO.NET could help me here, but I have not yet delved into this. Can anyone give me a few pointers to help me along?
Cheers!
Is there a setting in SQL Server that ensures a column is not allowed to have the same value more than once? Or must this be set up in the insert statment itself? Or how about a business rule?
View 2 Replies View RelatedI am writing a db conversion for a retail grocery chain. This chain uses pricing zones to designate what stores get a certain price
Example:
Cheetos
Zone A: $2.79
Zone B: $2.89
The pricing data in the tables is listed by zone. However, the new product uses pricing by store.
Zone A contains stores 1,2,4,6,7....
Zone B contains stores 10,11,12,14.....
I need to be able to duplicate the rows in a manner that I can take the row containing a price for Zone A and duplicate it for each store in the zone. I have a table of stores with corresponding zones.
So I'm looking to go from:
Zone UPC Price
A 1234500000 2.79
B 1234500000 2.89
To:
Store UPC Price
1 1234500000 2.79
2 1234500000 2.79
10 1234500000 2.89
11 1234500000 2.89
I want to change duplicate data in my sql server column.
the data= 'Barack Obama' , what I want
'Barack Obama 23453'
I have the following query:
UPDATE klant SET naamvoornaam=naamvoornaam + CAST(klantnummer AS VARCHAR)
WHERE naamvoornaam NOT IN (
SELECT(naamvoornaam)
FROM klant
GROUP BY naamvoornaam
HAVING ( COUNT(naamvoornaam) = 1 ))
Message from messages:
String or binary data would be truncated.
I think the max length exceeds the length of the destination column. I've tried:
Max(Len(naamvoornaam + CAST(klantnummer AS VARCHAR)))
message from messages:
An aggregate may not appear in the set list of an UPDATE statement.
I want to filter out the duplicate rows based on three columns. I got this quick query from Microsoft site to filter out the duplicate rows, but I am getting the result that filters out the non-duplicate one too. Below is the query
;With Temp as (
SELECT row_number() over (partition by [id],[p_date], order by [id],[p_date],) as Row,
[code]...
In the above case id is null, but in some rows id is not null . The above is obviously not duplicate.
I guess there is first for everything...I had never seen error like this before
Violation of PRIMARY KEY constraint 'PK_table1'. Cannot insert duplicate key in object 'table1'. The statement has been terminated.
In this case Primary Key is Identity column. I do not include Idenity column in Insert statement.
Incidently SQL server machines had cluster failure couple of days before. I am not sure whether it has anything to do with it.
I see this error randomly.
How should I debug it
In my employee table has the following fields empid, empFname, empLname, email, city
Say it has data like follows:
1, Lucy, Sam, l@some.com, city1
2. Sam, Wite, l@some.com, city2
3. Laura, Mac, l@some.com, city2
4. Stacy, Soo, s@no.com , city1
So in my case I want to show all the column but I want to eliminate multiple email addresses. I tried Distinct but its not workin because here every column is not distinct. So what should I use?
In my case I only want to show empID 1, 3, 4. I want to show all the columns
I have a stored procedure that returns a single row based on a parameter of employee ID. This particular procedure uses a CTE to traverse our org structure. One of the columns is returning a delimited string of Windows login values and due to the business rules, it can contain duplicate values. I need to have that column contain only unique values - no dupes.
For example, this one column could contain something like this:
domainuser1;domainuser2;domainuser2;domainuser 3;
The need is to convert to this:
domainuser1;domainuser2;domainuser3;
I know that's a tall order.
I have a query that produces unique rows. However, some of the unique rows have the column called testname that has the same test listed more than once. All I want to do is drop the older testname and keep the testdate column.
Select
Distinct
TestID,
TestDate,
TestName
From third.test
I want to keep testdate in the query....guessing I need to put in to a temp table then drop the oldest one somehow by doing a subquery using Select Max....
I want to fetch max of Field2 if duplicate records in Field1 and rest of the values of field1 , below is the sample format.
Field1 Field2 Field3 Field4
32 375 abc-xyz A
32 379 xyz-efg A
55 405 abc-xyz B
55 407 xyz-efg B
132 908 abc-xyz C
132 999 xyz-efg C
152 800 abc-xyz D
152 850 xyz-efg D
155 900 abc-xyz E
156 925 abc-xyz F
157 935 abc-xyz G
With the data example below I am trying to consolidate the duplicate rows by flattening the dealer and billcode, or putting those values in each of the columns instead of creating separate rows...

View 2 Replies View RelatedHello,
I have a table with an Identity Column set up. I also have an index on the table that is set to Ignore Duplicate. Identity starts at 1 and is incremented by 1.
So first 5 rows inserted get identity
1
2
3
4
5
If I insert rows that get ignored because of the index with Ignore Duplicate, it is ignored correctly. But, the next row to get inserted will have an identity value of 7.
So, even though the insert was ignored because of the index with Ignore Duplicate, the Identity column was incremented behind the scenes.
Is there any way to avoid this?
Thanks,
John
My data is like below:
ClassId ClassName StudentId Subject SubjectId
1 ESL 12 English 20
1 ESL 13 Science 30
1 ESL 12 Social 40
1 ESL 12 Maths 50
Required output: parameters are Subject column values
ClassId ClassName TotalStudents SubjectIds
1 ESL 1 20, 40, 50
1 ESL 1 30
When one student takes multiple subjects then count student only once, so in the above data 12 is one student id takes multiple subjects so counted only once. TotalStudents value is 1
I did write below query:
Declare @subjectids string
set @subjectids = '20,30,40,50'
-- will split @subjectids and store in temp table
select classname, classid, Count(Distinct StudentId)
from mytable
where SubjectsIds in @subjectIds
group by ClassId, ClassName, SubjectId,
but it gives me below output:
ClassId ClassName TotalStudents SubjectIds
1 ESL 1 20
1 ESL 1 30
1 ESL 1 40
1 ESL 1 50
I need write a query for removing duplicates, for Example in my table I have columns
A_ID name id
1 sam 10
2 sam 10
3 sam 10
4 sam 10
5 ccc 15
6 ccc 15
7 ccc 15
8 fff 20
9 fff 20
10 fff 20
So now I have duplicates values in id column so now I need to take only one value of each and delete the remaining. I need to take first id value 10,15,20 so only 3 rows should be there in my table.
I have 2 excel tables files.One table has info about sales by country, by model, by date...and the other table has units by date.Obviously, the common key is "date"....and by creating a relationship, I can add "units" to my combined resulting table.However, I can't create the relationship. Excel keeps telling me: "the relationship cannot be created because each column contains duplicate values. Select at least one column that contains only unique values".

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. "
There are 3 columns in the result set - part num, Qty and MO num. Each MO num has part numbers.So there might be same part numbers in MO's. Each part num has qty. So, if I group by part num, I get Qty.
1.There are duplicates of part.num and I want to remove duplicates and add quantities of those duplicates into one single quantity. For example, xxxx is a part num, then xxxx=1,xxxx=3,xxxx=5. I want xxxx=9. I want to sum those. Another question is, each MO has a user. I want to join user and MO num in MO.
Heres the code,
part.num , (woitem.qtytarget/wo.qtytarget) AS woitemqty,
(SELECT LIST(wo.num, ',') FROM wo INNER JOIN moitem ON wo.moitemid = moitem.id WHERE moitem.moid = mo.id) AS wonums FROM mo INNER JOIN moitem ON mo.id = moitem.moid

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.
Ideas?
Thanks,

Hello Everyone:
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.
How do I fix this?
TIA
Hello,
This probably has been addressed before but I was unable to get the search to work properly on this site.
I am needing a script/way of deleting all rows from a DB with the exception of one record left for each row that has duplicate column data. Example :
Row 1
Field1 = 12345 Field2 =xxxxx Field 3=yyyyy Field4=zzzzz etc.
Row 2
Field1 = 12345 Field2 =zzzzzz Field 3=xxxxxx Field4=yyyyyy etc.
Row3
Field1 = 12345 Field2 =20202 Field 3=11111 Field4=zzzzz etc.
Row 4
Field1 = 54321 Field2 =xxxxx Field 3=yyyyy Field4=zzzzz etc.
Etc. Etc.
I want to be able to find the duplicates for Field1 and then delete all but 1 of those rows.( I don't care which one I keep just so only one is left.) The data in the other fields may or may not be unique.
I know how to find the duplicates it's just the deleting part I am having problems with. Any help would be much appreciated. Thanks,
Kerry
I've begun to get the above error from my package. The error message refers to two output columns.
Anyone know how this could happen from within the Visual Studio 2005 UI? I've seen the other posts on this subject, and they all seemed to be creating the packages in code.
Is there any way to see all of the columns in the data flow? Or is there any other way to find out which columns it's referring to?
Thanks!
