Find Duplicate In Column Tied To Another Column

Apr 29, 2015

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

Transact SQL :: Find Unique Rows In Column That Are Associated With Another Field In Another Column?

May 1, 2015

I am having issues trying to write a query that would provide me the unique GUID numbers associated with a distinct PID if the unique GUID's > 1.  To summarize, I need a query that just shows which PID's have more than one unique GUID. A PID could have multiple GUID's that are the same, I'm looking for the PID's that have multiple GUID's that are different/unique. 

Table1

GUID PID
GUID1 PID1
GUID1 PID1
GUID1 PID1
GUID2 PID1
GUID3 PID2
GUID3 PID2
GUID3 PID2

The result of the query would only have PID1 because it has two unique GUID's. PID2 would not be listed has it has the same GUID3 in each row.

Result:

PID1

Sep 5, 2015

I was querying to find the first non null address value using the COALESCE function.And I got the correct result.But then I jumped into another question and i.e what if I need to find the column name without knowing the column nameand just by using the column value.What I mean is this...My query was.....

SELECT COALESCE(AddressLine1,AddressLine2) AS [Addresss] FROM Person.Address
This is what I got.
Address#500-75 O'Connor Street#9900 2700 Production Way00, rue Saint-Lazare02, place de Fontenoy035, boulevard du Montparnasse081, boulevard du Montparnasse081, boulevard du Montparnasse084, boulevard du Montparnasse1 Corporate Center Drive1 Mt. Dell Drive

But then what if I just know the address of that person i.e #500-75 O'Connor Street..How am I suppose to retrieve that without knowing the column name.

Duplicate Counts Per Column

Nov 6, 2006

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

Searching A Column For A Value To Avoid Inserting A Duplicate Value

Jul 17, 2007

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!

Setting That Disallows Duplicate Values In A Column?

Jul 19, 2007

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?

Create Duplicate Rows With One Column Changed

Mar 12, 2013

I 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

Change Duplicate Data In Server Column

Oct 17, 2014

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.

Filtering Out Duplicate Rows Based On Three Column

Nov 25, 2014

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.

'Cannot Insert Duplicate Key' Error With Identity Column As PK

Feb 18, 2008



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

Removing Duplicate Delimited Values From A Single Column?

Jun 18, 2014

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.

Identity Column On Table And Ignore Duplicate On Index

Mar 27, 2007

Hello,

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

1         ESL       13         Science     30

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
