Cross Tab Or Derived Table

Jul 20, 2005

Hi all,

I have a table in this format

colname1 colname2 colname3
col1data1 col2data1 col3data1
col1data2 col2data2 col3data2
col1data3 col2data3 col3data3
col1data4 col2data4 col3data4

I want to display it in this format

colname1 col1data1 col1data2 col1data3 col1data4
colname2 col2data1 col2data2 col2data3 col2data4
colname3 col3data1 col3data2 col3data3 col3data4

Basically rotate it through 90 degrees clockwise and flip it over :)

I'm pretty sure this is done by using a crosstab query and or a
derived table or temp table. The problem is I use a crosstab query to
get the original data into the first format. I've been struggling
trying to get the ouptput into the second format for over a day now
and just can't seem to get it to work. Can anyone give me any pointers
on the general solution to this?

I hope this makes sense. Thanks for the help.

Sir,

My query is

Cross Join Without Table?

Feb 1, 2005

I have the following structure with remote select permissions; I cannot create temp tables or use stored procs:

tblEvent with event_pk, eventName
tblReg with reg_pk, event_fk, person_fk, organization_fk

I'm currently using a case statement to get counts for these categories:
case
when c.person_fk is Null and c.organization_fk is not null then 'Employer'
when c.person_fk is Not Null and c.organization_fk is null then 'Individual'
when c.person_fk is not Null and c.organization_fk is not null then 'Both'
else 'Unknown'
end

But I need some kind of count (0) for every category. I've used a cross-join, group by in the past - but what do you do if you don't have a table? For example, the end result when selecting event_pk=(112,113) would be:

event_pk, myCount, countCat
112 0 Employer
112 1 Individual
112 4 Both
112 0 Unknown
113 5 Employer
113 0 Individual
113 0 Both
113 2 Unknown

Thanks for any help,

Cross Tab/Pivot Table/UDF?

Mar 27, 2004

I have the following tables:


tbTemplateShapeProperties
fkTemplate | fkProperty | PropertyValue
-----------------------------------------------
1 | 1 | 192
1 | 2 | 36
1 | 3 | 4
1 | 4 | 5
1 | 5 | 2

tbShapeProperties
Property | PropertyName | fkShape
----------------------------------------------
1 | Width | 1
2 | Height | 1
3 | Flange | 1
4 | Avg. Leg Width | 5
5 | Leg Count | 2


From the above I wanted to create a pivot table, from there I want to pass the column values through to a UDF

XSection (Width, Height, Flange, Leg, LegCount)

I tried the following to get a pivot table but it does not give a single row but 5.


SELECT CASE sp.PropertyName WHEN 'Width' THEN tsp.PropertyValue ELSE 0 END AS Width,
CASE sp.PropertyName WHEN 'Height' THEN tsp.PropertyValue ELSE 0 END AS Height,
CASE sp.PropertyName WHEN 'Flange' THEN tsp.PropertyValue ELSE 0 END AS Flange,
CASE sp.PropertyName WHEN 'Avg. Leg Width' THEN tsp.PropertyValue ELSE 0 END AS Leg,
CASE sp.PropertyName WHEN 'Leg Count' THEN tsp.PropertyValue ELSE 0 END AS LegCount
FROM tbTemplateShapeProperties AS tsp INNER JOIN tbShapeProperties AS sp
ON tsp.fkProperty = sp.Property
WHERE tsp.fkTemplate = 1


The following results are returned:

Width | Height | Flange | Leg | LegCount
----------------------------------------------
192 | 0 | 0 | 0 | 0
0 | 36 | 0 | 0 | 0
0 | 0 | 6 | 0 | 0
0 | 0 | 0 | 5 | 0
0 | 0 | 0 | 0 | 2


The desired result as you could guess is:

Width | Height | Flange | Leg | LegCount
----------------------------------------------
192 | 36 | 6 | 5 | 2


So, this leaves me with one question, even if I was to get this to work, is is possible to then extract the values and pass them through to the UDF within the same stored proc?

Any hints?

Cross Reference Or Pivot Table

if @@rowcount = 0  select 'No Records found'GO
2. I've use this store procedure for many cross reference successfully. But this time my cross reference value (resultcode) is a varchar which cannot be convert to int or decimal in sql, Probably, you've noticed that the fourth parameter is a function.    how can i modify SimpleXtab to avoid using math function but still can generate cross reference.
   exec simplextab2 'Sequence','##tbltempreport',' ','sum','resultcode','Parameter' ,'dbo.resultcodetable'
 
Many Thanks!

Cross Table Multiplication Query

Mar 30, 2012

I am currently building a website to deal with different product information and sales with php. I am using SQL to sort the database and pull out information.

The final thing i need to do is work out the total revenue of each product however the problem i am having is that the 'Price' column and 'SalesVolume' column are in two different tables and they need to be multiplied together.

The two tables and column headings are as follows:

Product
ID
Name
Price

MonthlySales
ID
ProductCode
Month
Year
SalesVolume

(ID and ProductCode are linked together in a relationship)

I cannot see anything wrong with the syntax in my query however i believe there is.

Here is the query I am using:

Code:
"SELECT SUM(Products.Price * SUM(MonthlySales.SalesVolume)) as revenue FROM Products
INNER JOIN MonthlySales ON(Products.ProductCode = MonthlySales.id) GROUP BY Products.ProductCode";

Inserting A Derived Value Into A Table

Feb 28, 2008

Hi,
I have built a database for a university project, but am having trouble with the SQL syntax for inserting derived data from a calculation into a table.  At present my SQL is;
INSERT INTO MemberPayment (TotalCharge) VALUES ( [Total] )
SELECT ((MileageHistory.MileageUrban * Vehicle.EmissionsPerGramUrban) * 0.05) + ((MileageHistory.MileageCountry * Vehicle.EmissionsPerGramUrban) * 0.05) AS 'Total'
FROM [NeuCar].[dbo].[MileageHistory] JOIN [NeuCar].[dbo].[Vehicle]
ON MileageHistory.Registration = Vehicle.Registration
JOIN [NeuCar].[dbo].[Member] ON Vehicle.UserName = Member.UserName
WHERE Member.UserName = 'wenger1' AND (MileageHistory.[Date] >= CURRENT_TIMESTAMP - 30);
Would anybody be able to point out where I am going wrong? I would very much appreciate any advice,
Kind regards,

Derived Table Not Updatable

Oct 6, 2004

I got an error as follows:
Derived table 'A' is not updatable because a column of the derived table is derived or constant.
when I tried to run this query:
update A set MonthsUnbilled =99999888
FROM (select MonthsUnbilled from dbo.vw_MasterView
WHERE (RecordID =8377396)) A
This is a simplified query in order to pinpoint the culprit. I know I don't need to use a derived table if the real query is this simple.

Thanks in advance!

Do I Need A Derived Table For This Situation

Feb 1, 2007

OBJECTIVE:THE QUERY SHOULD GIVE ME THE FIELDS I MENTIONED IN THE FIRST QUERY WITH THE CONDITIONS BELOW.
CONDITION 1: RateReview field should have yesterday's date
CONDITION 2: Email will be send to customer only once so Customer_GUID is UniqueIdentifier
CONDITION 3: Customer shouldnt' have opted to get out from receiving any email so Termination field should be NULL
ONe Customer can have many transwactions
Is there any way i write the code specifying that no email should be sent more than once evereven if customer buys 10 tickets.
Only one email sent so i need to specify that if this email has gone to particulare CUSTOMER_GUID then Ignore that record and
do not send any email. This would be done by some tool known as StrongMail.
SELECT
CAST(a.Transaction_GUID AS varchar(36)) as Transaction_GUID,
CAST(a.Customer_GUID AS varchar(36)) as Customer_GUID,
Film_id as MovieId,
First_nm as FirstName,
Last_nm as LastName,
Email_nm as EmailAddress
FROm
Table1 where RateReview_dm >= dateadd(day, datediff(day, 0, getdate()), -1) -- Greater or same as Yesterday day
and RateReview_dm < dateadd(day, datediff(day, 0, getdate()), 0) -- Less than today's date
and
and Terminate_dm is null
(I don;t know what condition to give that same customer good should not be send email again if send once)
i don't know whether i need to create a derive table or it can work without drive table

Cananyone help me with this query please

Derived Table Alternative

Feb 7, 2007

I have an application that has two different database backends, one is SQL Server Compact Edition and the other is SQL Server. The reason is because the application may run at home on one of our sales agent's computers or here in the office.

I have a query that uses a derived table and works just fine in SQL Server, however when I run it in the compact edtion (having the exact same table structures) it will not run. My question is...does the Compact Edtion or the Mobile Edition allow derived tables. If not is there a way to work around this? I will happily give an example if it will help.

Thank you,

Questions On Derived Table

Jul 31, 2007

I have some questions on derived table. Below is my situation.

Table order, there are 40 columns and it has indexes for productID and addressID
Table product, there are 15 columns and it has index for productID
Table address, there are 20 columns and it has index for addressID

Query A
-------
select C.address, C.area, B.productname, B.category, A.qty, A.price
from order A
join product B
on A.productID = B.productID
join address C
on A.addressID = C.addressID

Query B
-------
select C.address, C.area, B.productname, B.category, A.qty, A.price
from (select qty, price, productID, addressID from order) A
join (select productID, productname, category from product) B
on A.productID = B.productID
join (select addressID, address, area from address) C
on A.addressID = C.addressID

Will I loss the indexing when using derived table?
Why query B performance is much better than query A?

Thanks.

MAX Of TOP In Derived Table Behaving Strange

Feb 19, 2008



Hi,

I am working for my client on SQL 2005 Enterprise & observed a strange behaviour. Consider a table(EMPTABLE) as below:









PK, INT

VARCHAR


EMPID

EMPNAME


1

A


2

B


3

C


4

D


5

E


6

F


7

G


8

H


9

I


10

J


Now, I wanted the 5th highest EMPID from 2 from the table. Now, we know that the SQL

SELECT TOP 6 EMPID FROM EMPTABLE WHERE EMPID >=2 should (from all other possibilities) return me the desired value as the last row of the output table. I tried to get this in a derived table & get the MAX value i.e.

SELECT MAX(EMPID) FROM
(
SELECT TOP 6 EMPID FROM EMPTABLE WHERE EMPID >=2
) der

But this returns me 10, when I would've thought 7 was the expected answer

I remodified my query as mentioned below to strangely get 7 as the result...
SELECT MAX(EMPID) FROM
(
SELECT TOP 6 EMPID FROM EMPTABLE WHERE EMPID >=2 ORDER BY EMPID ASC
) der


How did the ORDER BY hep it???

Also, if I use
SELECT MAX(EMPID) FROM
(
SELECT TOP 6 EMPID FROM EMPTABLE WHERE EMPID >2
) der


I get the same result without having to specify the ORDER BY in my derived TABLE...

I tried looking for similar threads. But nothing could explain this to me...

If anyone knows what I am not able to understand, please let me know.

How To Synthesize A Single Row Result From A Cross-referenced Table?

Jan 13, 2008

Hello, I have an SQL problem that is hard to describe so here's an example scenario:

a) company has a personnel database, identifying each person in the company and their assigned role(s).

b) tblPersonnel has a row per person, key is 'PersonnelID'
c) tblRoles is a list of all the roles in the company (administrator, clerk, shipper, truck-driver, etc.), key is 'RoleID'

d) tblPersonnelRoles is a cross-reference of all the roles assigned to each person - in simple format of:

PersonnelID | RoleID


Given all the above, I need to have a select statement that produces one row per person, and list all the fields from tblPersonnel AS WELL AS identifies each role assigned to the person.

I'm no SQL guru .. is this even possible?

I know there are alternative solutions (e.g., to write code that for each Personnel does a lookup in Roles) but for one particular situation I need a single SQL statement, or even Stored Procedure.

Thanks in advance,

Searching A List Of Tables, Derived From Another Table

Sep 21, 2005

Relative SQL newbie here......this is probably easy, but....Lets say I have a table (MainTable) that stores a list of input table names,a primary key (PKey), and a field called "Configured" for each one. Each ofthese input tables also contain a field called "Configured", which is set totrue or false in another process based on an OrderNumber. (So an order'sinputs are stored in several input tables, and the MainTable is a summarytable that shows which input tables have been configured for any givenOrderNumber).What I need to do is open each input table, and look for a record containinga specific OrderNumber and where Configured=true. If a record is found, Ineed to update the Configured field for that table in the MainTable, andthen move on to the next sub-table.The way I'm doing it now is with simple SQL and loops. Here is the basiccode (ASP):*****************************************OrderNumber = "562613" ' the current order that is being processed' reset all configured flagssql = "UPDATE MainTable SET Configured = 0"conn.execute sql, , &H00000080' get list of all tablenamessql = "SELECT InputTableName, PKey FROM MainTable WHERE InputTableName <>'---'"set rsTableNames = conn.execute(sql)while not rsTableNames.eof' test each input table for configured flagsql = "SELECT Configured FROM " & rsTableNames("InputTableName")& _" WHERE Configured = 1 AND OrderNumber = '" & OrderNumber &"'"set rs = conn.execute(sql)If Not rs.EOF Then' update the main tablesql = "UPDATE MainTable SET Configured = 1 WHERE PKey='" &rsTableNames("PrimaryKey") & "'"conn.execute sql, , &H00000080end ifset rs = nothingrsTableNames.movenextwend*****************************************There has to be a faster way.. I think.... maybe something that could bewritten as a stored procedure? I use a similar technique in a couple ofother places and it's a bit of a performance hit, especially as the numberof input tables grows.TIA!Calan

2 "A" "B"



but like I said before, I can't repeat the query that gets the first 2 rows, as it's pretty invovled. a temp table is the best route I see right now, but I just wanted to be sure I'm not missing something. If I've aliased it as 'results', is there a way to alias results again as something else? or maybe a trick with CTEs? I will try that! It seems promising.

Combine 2 Rows From Derived Table Into 1 Row W/o Repeating Query?

Aug 1, 2007



I'm trying not to use a temp table, but i may have to do so..

i have a derived table that makes the following results:

ID Status Name
2 1 "A"
2 2 "B"

I want to get the following:
ID Name1 Name2
2 "A" "B"

but like I said before, I can't repeat the query that gets the first 2 rows, as it's pretty invovled. a temp table is the best route I see right now, but I just wanted to be sure I'm not missing something.

SQL Server 2012 :: Derived Table To Extract Value Of Account For Comparison

Nov 2, 2014

In my TSQL code i use a derived table to extract the value of account 321 to compare if they are the same that the SUM of my line invoice cost multiply by quantity line : Sum(fi.ecusto*qtt)

This is my script:

SELECT ft.ndoc [Doctype],ft.fno [Docnr] , Sum(fi.ecusto*qtt) [totalcostof my Invoiceline], xctb.conta [accountancy account],
sum(Case when ft.tipodoc = 1 then Xctb.ecre else Xctb.edeb end) as [Value of Cost of invoice in accountancy],
[DIF] = Sum(fi.ecusto*qtt) - Sum(Case when ft.tipodoc = 1 then xctb.ecre else xctb.edeb end)

[Code] ....

My problem is if i have more than on line on my invoice, for example 2 lines, the value of column [Value of Cost of invoice in accountancy] are duplicated, for 3 line invoice the value are multiply by 3.

SQL Gets Corrupted With 'WITH' Command And Rubbish When Editing Query Containing Derived Table

Jan 31, 2008

When my colleague makes any change to a query containing a derived table, the word 'WITH' followed by a lot of graphical characters appears after the alias, rendering the query unusable. We have tried this with various existing and new, simple queries, all to no avail. We are editing the queries in Visual Studio 2003, and he does not get this effect when using Visual Studio 2005. I can edit the query in 2003 on my laptop with no ill effects.

Help!

Request For Confirmation Of SQL 2005 Optimiser Bug With Derived Table And Convert()

Jul 23, 2007

I have discovered what looks like a bug in the optimiser. I've posted it at https://connect.microsoft.com/SQLServer/feedback/ViewFeedback.aspx?FeedbackID=288243 but I wonder if any of you with SQL 2005 RTM, 2005 SP1 or 2008 CTP could confirm when this was introduced and whether it is still an issue?






Code Snippet

-- Bug report

-- 2007/07/19

-- Alasdair Cunningham-Smith

-- alasdair at acs-solutions dot co dot uk

set nocount on

go

-- example date in in British date format

set dateformat dmy

go



use tempdb

go



create table foo( bar varchar( 30 ) not null )

go



insert into foo( bar ) values ( 'fishy' )

insert into foo( bar ) values ( '19/07/2007' )

go



-- this works fine in all versions - only valid dates are passed to the convert function

select

convert( smalldatetime, bar, 103 ) as bardate

from

foo

where

bar like '__/__/____'

go



-- this works on SQL 2000, but fails on SQL 2005 SP2 (I've not tried other SPs of SQL 2005):

-- Msg 295, Level 16, State 3, Line 2

-- Conversion failed when converting character string to smalldatetime data type.

--

-- I believe the query is rewritten as if the derived table query contained

-- "and convert( smalldatetime, bar, 103 ) < getdate()"

-- which would expose the convert to the invalid data

select

*

from

(

select

convert( smalldatetime, bar, 103 ) as bardate

from

foo

where

bar like '__/__/____'

) as derived

where

bardate < getdate()

go



-- Workaround:

-- Use a case statement to protect the convert operator from the invalid data

select

*

from

(

select

case when bar like '__/__/____' then

convert( smalldatetime, bar, 103 )

else

null

end as bardate

from

foo

where

bar like '__/__/____'

) as derived

where

bardate < getdate()

go



drop table foo

go



The workaround I discovered is simple but ugly. I invite your comments...

T-SQL (SS2K8) :: How To Vary Column Names In Cross Apply Based On Different Columns In Each Table

Feb 26, 2015

I am using CROSS APPLY instead of UNPIVOT to unpivot > one column. I am wondering if I can dynamically replace column names based on different tables? The example code that I have working is based on the "Allergy" table. I have thirty more specialty tables to go. I'll show the working code first, then an example of another table's columns to show differences:

select [uplift specialty], [member po],[practice unit name], [final nomination status]
,[final uplift status], [final rank], [final uplift percentage]
,practiceID=row_number() over (partition by [practice unit name] order by Metricname)
,metricname,Metricvalue, metricpercentilerank

[code]....

Rheumatology Table:The columns that vary start with "GDR" and [GDR Percentile Rank] so I'm just showing those:

GDR (nvarchar(255), null)
GDR Percentile Rank (nvarchar(255), null)
GDR PGS (nvarchar(255), null)
GDR Rank Number (nvarchar(255), null)
PMPM (nvarchar(255), null)

[Code] ....

These are imported from an Excel Workbook so that's why all the columns with spaces for now.

Using Foreach Loop To Parse An SQL Table - Lookup And Create Derived Column

Oct 25, 2007

I am looking for the best way in SSIS to do the following. I have an SQL table that for each row in the table I want to take an element from the table do a lookup in a Teredata Table, return information from the teredata source. Use that returned data to do some calculations and create a derived column from my calculations and place the data into the same SQL table that I am parsing through.

Ideas?
