SQL Server 2012 :: Duplicate Values In UNPIVOT

Feb 18, 2015

I have a set of data in which i have a product number going through 6 stages and each stage has a date. Since the each stages are in columns, I have created a unpivot query to transpose the columns into rows.

The actual result data needs to be in format of

ProductNumber Event_NameEvent_Date Event_Days
101 Stage 1 2/13/2014 1
101 Stage 2 2/13/2014 0
101 Stage 3 2/18/2014 5
101 Stage 4 2/23/2014 5

However the result data i am getting is like

ProductNumber Event_NameEvent_Date Event_Days
101 Stage 1 2/13/2014 1
101 Stage 1 2/13/2014 0
101 Stage 1 2/18/2014 5
101 Stage 1 2/23/2014 5
101 Stage 2 2/13/2014 1
101 Stage 2 2/13/2014 0
101 Stage 2 2/18/2014 5
101 Stage 2 2/23/2014 5

The unpivot query is working fine however I am getting duplicate values in the result. For each productnumber there must be only 6 results however i am getting 24 rows for each product number due to duplication.

I have attached the code and the source data for reference

Code:
SELECT distinct ProductNumber ,
Event_Name ,
Event_Date ,
Event_Days
FROM(
SELECT ProductNumber ,

SQL Server 2012 :: Reducing Duplicate Row Because Of Different Column Values?

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...

SQL Server 2012 :: Using Cross Apply To UNPIVOT Data

Jan 15, 2014

I was reading Kenneth Fisher's and Dwain Camps' articles on unpivoting using cross apply... And I can actually get them to work....

CREATE TABLE #TxCycle(
Cycle INT NOT NULL,
PatientID INT NOT NULL,
ALOPECIA TINYINT,
Causality1 TINYINT,
Relatedness1 TINYINT,

[Code] ....

The one thing I was wondering was this: how do I extract the symptom names from the field list without knowing them all beforehand? Dwain does this

-- DDL and sample data for UNPIVOT Example 2
CREATE TABLE #Suppliers
(ID INT, Product VARCHAR(500)
,Supplier1 VARCHAR(500), Supplier2 VARCHAR(500), Supplier3 VARCHAR(500)
,City1 VARCHAR(500), City2 VARCHAR(500), City3 VARCHAR(500))

Can this be adapted if you don't know all the column names beforehand? (Likely not). Back in the dark ages, when I was working on a database like this, it was in Access, and I could loop over the fields collection and evaluate each field name. (Yes, I know you're not supposed to store information in field names, but I inherited that mess!)

NULL Values In UNPIVOT Output Possible?

Feb 26, 2008

Hello everyone!

Maybe someone of you folks already stumbled upon this one and can help.


I'm using an Unpivot transform in a dataflow.
I want to unpivot various columns that are all of type dt_str(50).
Some of those (input) columns may contain NULL values in some rows, like this:





col1
col2
col3
col4

BusinessKey
val1
NULL
val3
val4


As I run this package, I'd expect the Unpivot's output looking like this:




BusinessKey
col1
val1

BusinessKey
col2
NULL

BusinessKey
col3
val3

BusinessKey
col4
val4

But Unpivot won't output a Key/Value pair if an input value is NULL.
So in fact the output looks like this (col2 is missing):




BusinessKey
col1
val1

BusinessKey
col3
val3

BusinessKey
col4
val4


The BOL documentation doesn't tell anything about Unpivot behaviour if input values are NULL (or at least I couldn't find it).


Now, is this a known problem?
If so, is there a fix or workaround so that I can tell Unpivot to output NULL values?


Thanks for your help!

Unpivot Transformation Null Values

Hi, I am trying to use the Unpivot Transformation, and I have the following mapped out, following the example from the SQL Server 2005 BOL Unpivot Transformation:

This doesn't work, however, as I have multiple data types. So unless someone knows a better way, I had to split it into two Unpivot Transformations, which I later Sort and Merge together. The two Unpivot Transformations look like this:

NULL


77777
GENDER
NULL


77777
OTHRRACE

The first Unpivot works great, because the data is mandatory. However, the second is full of NULLs so the actual output from the second Unpivot, prior to the merge looks like this:









Actual Output



Subject
Question
ValueString

99999



88888
OTHRRACE
Hispanic

77777



But I expected (and need) this:









Desired Output



Subject

99999
OTHRRACE
NULL

88888
OTHRRACE
Hispanic

77777
OTHRRACE

I hope someone can give me some advice on this!

Can You Unpivot On Multiple Keys With The Unpivot Transform

Oct 17, 2006

Hi all,

I have more than 1 set of columns I'm trying to normalize, can an unpivot transform handle 2 unpivots around DIFFERENT keys in the same transform?

If not, would the suggestion be unpivot into temp tables for whatever needs normalizing, than run an update query to generate the row that is desired?

Thanks in advance.

SQL Server 2012 :: Replace All Values In String With Values From Look Up Table

Mar 19, 2014

I have a table that lists math Calculations with "User Friendly Names" that look like the following:

([Sales Units]*[AUR])
([Comp Sales Units]*[Comp AUR])

I need to replace all the "User Friendly Names" with "System Names" in the calculations, i.e., I need "Sales Units" to be replaced with "cSalesUnits", "AUR" replaced with "cAUR", "Comp Sales Units" with "cCompSalesUnits", and "Comp AUR" with "cCompAUR". (It isn't always as easy as removing spaces and added 'c' to the beginning of the string...)

The new formulas need to look like the following:

([cSalesUnits]*[cAUR])
([cCompSalesUnits]*[cCompAUR])

I have created a CTE of all the "Look-up" values, and have tried all kinds of joins, and other functions to achieve this, but so far nothing has quite worked.

How can I accomplish this?

Here is some SQL for set up. There are over 500 formulas that need updating with over 400 different "look up" possibilities, so hard coding something isn't really an option.

DECLARE @Synonyms TABLE
(
UserFriendlyName VARCHAR(128)
, SystemNames VARCHAR(128)
)
INSERT INTO @Synonyms
( UserFriendlyName, SystemNames )

[Code] .....

SQL Server 2012 :: Dropping Rows With Duplicate Column Name

Feb 13, 2014

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....

SQL Server 2012 :: Select Statement - Finding Duplicate Records

Feb 18, 2014

I am trying to build a select statement that will

1). find records where a duplicate field exists.
2.) show the ItemNo of records where the Historical data is ' '.

I have the query which shows me the duplicates but I'm stuck when trying to only show records where the Historical field = ' '.

Originally I thought I could accomplish this goal with a sub query based off of the original duplicate result set but SQL server returns an error.

Below you will find a temp table to create and try in your environment.

create table #Items
(
ItemNovarchar (50),
SearchNo varchar (50),
Historical int

[Code] ....

Ultimately I need a result set that returns 'ATMR10 MFZ N', and 'QBGFEP2050 CH DIS'.

SQL Server 2012 :: How To Group Near Duplicate Records Under A New Common Field

Aug 26, 2015

I've inherited a table of members that has the following structure:

CREATE TABLE [dbo].[dimMember](
[dimMemberId] [int] IDENTITY(1,1) NOT NULL,
[dimSourceSystemId] [int] NOT NULL CONSTRAINT [DF_dimMember_dimSourceSystemId] DEFAULT ((-1)),
[MemberCode] [nvarchar](50) NOT NULL,
[FirstName] [nvarchar](250) NOT NULL,
[LastName] [nvarchar](250) NOT NULL,

[Code] ....

Based on the way the data loads into the table there's a possibility of some records being near duplicates of each other. For example, we can have a member that has records that have the same first name, last name, SSN, but different addresses, membercodes, subscribercode etc... This can happen in pretty much any variation thereof.

What I want to do, is add a new column and use that to group the similar records under based on comparing on several columns. By this I mean, if a member matches 4 of the 7 values below with another member, we would group these:

First Name (1st 3 characters)
Last Name
DOB
CurrentAddress1
MemberCode
SSN
SubscriberCode

I'm at a loss of how to structure the SQL to update the new column in the table.

SQL Server 2012 :: Finding Duplicates And Show Original / Duplicate Record

Nov 3, 2014

There are many duplicate records on my data table because users constantly register under two accounts. I have a query that identify the records that have a duplicate, but it only shows one of the two records, and I need to show the two records so that I can reconcile the differences.The query is taken from a post on stack overflow. It gives me 196, but I need to see the 392 records.

How to identify the duplicates and show the tow records without having to hard code any values, so I can use the query in a report, and anytime there are new duplicates, the report shows them.

SQL Server 2012 :: Duplicate Of Part Num To Be Summed And Add Another Column Called User

Aug 25, 2015

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

LEFT JOIN wo ON moitem.id = wo.moitemid

LEFT JOIN woitem ON wo.id = woitem.woid AND woitem.typeid = 10 LEFT JOIN (Select sum(woitem.qtytarget) as labor, woitem.woid, uom.code as uom from woitem JOIN part on woitem.partid = part.id and part.typeid = 21 JOIN uom on woitem.uomid = uom.id group by 2,3) as labor on wo.id = labor.woid LEFT JOIN part ON woitem.partid = part.id

Duplicate Values

Apr 14, 2004

I have a table which is a license holder table (i.e., plumbers, electricians etc...) There are some people who appear in the table more than once as they have more than 1 type of license. I am tasked with querying out 200 of these people a week for mailing a recruitment letter which I am doing using the following select statement:

SELECT TOP 200 Technicians.Name, Technicians.Address, Technicians.City, Technicians.State, Technicians.ZipCode, Technicians.LicenseType
FROM Technicians

My problem is that this doesn't deal with the duplicates and distinct won't work because I need to pass the license type and that's the one field that's always distinct while the name and adress fields duplicate.

Duplicate NAME Values

Oct 12, 2007



Hi Guys!

I am trying to figure out a query to which the logic is simple, but I'm missing some basic SQL skill or technique somewhere.....

I have a table called NAME, from which I want to display the following columns:

namecode name Postaladdress

(there's a column called NAME as well as the table being called name incase your wondering)...

I'm concerned with the namecode and name columns for now....

I want to find duplicate name values from the table, how do I do this?

for example, in name, I have the value 'Long water Beach' appear twice. I want the query to show me how many times this appears from this table (duplicate values??)

Both namecode and name are navchar datatypes. So far I tried something like:


select name, namecode, postaladdress
from name
where name in
(select name
from name
group by name, namecode, postaladdress
having count(name) > 1)


I guess we can focus on the subquery here, but I just need that function or code which shows me the duplicate values!! I know its something staring me in the face, but I just can't see it!!

Any help please???

Much appreciated

Getting Duplicate Identity Values In SQL 6.5

Aug 26, 1998

We are experiencing a problem at more than one site - it has only
just started happening.

We are actually getting duplicate Identity column values in various
tables and the values seem random - its not like the counter just gets
wound back.

We have used dbcc checkident and also bcp out and in the data, which
of course corrected the tables but only temporarily. Our application
is not doing any select into`s - just plain old inserts which for some
reason are allowing dups to be inserted into the tables.

problem sites are either sp3 or sp4.

There are thousands of sites (including most of ours) where there are
no problems like this with this particular app.

Any help from anyone would be most appreciated.

Counting Duplicate Values

Nov 12, 2004

I know this question has been asked before but this is a little different and I can't seem to get my head around it right now.
What i have is a table like so:

ID1 ID2 DESC
100 24 something1
100 24 this is a test
100 24
100 25 somethingelse
101 36 something
101 37 something else altogether

What i need is to determine which ID1 value has the same ID2 value listed more than once WITH the description filled in. If there is no description filled in even though the ID2 may be listed twice on one ID1, then it's ok and don't want it displayed in the query.

So, in this case, ID1 of 100 has ID2 24 listed twice with a description on both ID2's (of 24). this is what I need to show up in the query like so:

ID1 ID2 DESC
100 24 something1
100 24 this is a test

Could someone give me a hand with this? I've found similiar problems...but haven't been able to apply those answers to this.

Thx

Duplicate Reference Key Values

Mar 29, 2007

HI, I keep getting this warning with a lookup (full cache mode) that retreives data form a table that contains the following information:

SRCE_SYS TABLE_NAME FIELD_NAME CODE ENGLISH_DESCRIPTION
STATIC STATIC PM_PC_TX_TYPE_CODE G GROSS
STATIC STATIC PM_PC_TX_TYPE_CODE E EXCESS
STATIC STATIC PM_PC_TX_TYPE_CODE F FACULTATIVE
STATIC STATIC PM_PC_TX_TYPE_CODE S SURPLUS
STATIC STATIC PM_PC_TX_RIDER_CODE BOAT BOAT
STATIC STATIC PM_PC_TX_RIDER_CODE RIDER RIDER
STATIC STATIC PM_PC_TX_RIDER_CODE CONT CONTENTS



The column tab matches SRCR_SYS, TABLE_NAME and FIELD_NAME (using constants defined in a derived column transform) .The code column comes from the source. We want to retreive the english_description colum from SRCR_SYS, TABLE_NAME,FIELD_NAME and CODE in the dataflow.



I would normally ignore the warning but sometimes, it seems that the lookup does not match any values and enabling memory restriction on the advanced tab resolve the issue and suppress the warning.



As I said, I keep getting this warning and I don't know why since there are no duplicates in the table? Am I missing something?



Thank you,

Christian

SQL Server 2012 :: Read All Values From XML Node?

I have the following code and trouble reading values of Bank Accounts. If i remove the line it says "xmlns="http://applications.apch1.com/webservice/schema/" then i my query is working. But i cant remove this becasue that is what i will get response from a web service. All the records are stored in the database with this line included.

SQL Server 2012 :: How To Match Values From A PIVOT

Jan 31, 2014

I'd like to get a extract table result, with a reference id primary key, showing the maximum dates for events and who was responsible for them. I can get the max(date) field in columns using PIVOT, but can't see a way to get the 'who' field without lots of LEFT JOINs.

Here's some test data and code which shows the principle:

CREATE TABLE #t
(
ref INT ,
id INT ,
who VARCHAR(10) ,
checkin DATE

[Code] ....

The result set is:

ref 1 who1 2 who2 3 who3 4 who4
123 2014-01-18 carol 2014-01-18 andy 2014-01-16 bill 2014-01-17 carol
456 NULL NULL 2014-01-17 NULL NULL NULL NULL NULL

Is there some way to avoid all the LEFT JOINs, maybe by using another PIVOT, to produce the same result?

SQL Server 2012 :: Get List Of Last Non Null Values

Feb 10, 2014

I have two tables, a dates table and a values table. They are joined on the date column.The date table has a range, say from today as far as 20 days from now, incrementing by 1 day each row.The values table may have a row for a day, and may not. If the day has a value I want to display that value.If the day does not have a value in the values table I want to display the last known value.

I think this can be done with windowing functions in a set based manner but have not been able to work it out. I have done it procedurally but im not happy with that at all, and really want to see if this is possible in a set based manner.Below is some simplified code to allow testing with sample data.

create table DimDate
(
DateCol date
)
create table TotalsData
(
DateCol date

[code]....

SQL Server 2012 :: Finding Breaks In Key Values?

Jun 12, 2014

The following is sample data I am dealing with.

SELECT * INTO TEMP
FROM
(SELECT 'AAAAA' AS CATEGORY, 'A1000' AS CODE, '01-01-2014' AS STARTDATE, '01-31-2014' AS ENDDATE
UNION
SELECT 'AAAAA' AS CATEGORY, 'A1000' AS CODE, '02-01-2014' AS STARTDATE, '02-28-2014' AS ENDDATE
UNION
SELECT 'AAAAA' AS CATEGORY, 'A1000' AS CODE, '03-01-2014' AS STARTDATE, '03-31-2014' AS ENDDATE
UNION
SELECT 'AAAAA' AS CATEGORY, 'A2000' AS CODE, '04-01-2014' AS STARTDATE, '04-30-2014' AS ENDDATE
UNION
SELECT 'AAAAA' AS CATEGORY, 'A1000' AS CODE, '05-01-2014' AS STARTDATE, '05-31-2014' AS ENDDATE) X

I need to extract the date that the value in CODE column changes to another code for each value of CATEGORY and if there is no change, to record the original CODE value and its startdate for each CATEGORY.
