Hi,
How to convert rows into columns with the help of decode function in oracle.
thanks and regards
P Prakash

say
col1 col2
1 10
2 20
3 30
then use
select col1,
sum(decode(col2,10,10)) "new1"
sum(decode(col2,20,20))"new2"
sum(decode(col2,30,30))"new3"
from table_name
group by col1;
we used sum u can use ny function if wont u have to give the column name i.e col2 name also
so i think u got it nw

How to convert row into column

Hi All,
My oracle apps version is r12 and db is 10 and i am using Bi publisher version 10g.
Is it possible to convert row into column in Rtf template,
My Query is
SELECT distinct pvs.vendor_site_code,sum(aia.invoice_amount)
FROM ap_invoices_all aia, po_vendors po, po_vendor_sites_all pvs
WHERE aia.org_id = pvs.org_id
AND aia.vendor_id = po.vendor_id
AND aia.vendor_site_id = pvs.vendor_site_id
AND aia.org_id=204
group by pvs.vendor_site_code
And output is like this
Vendor sitecode Invoiceamt
EAM-ERS 79240
STAR GATE - PAY 3245902.31
UPS - HQ 10792040.9
Like this
So in template i need the output like this
Vendor sitecode EAM-ERS STAR GATE - PAY UPS - HQ
Invoiceamt 79240 3245902.31 10792040.9
I tried to achieve the output using sql query but by hardcoding only i have achieved it, so i have tried to convert directly in RTF template.
can any one tell me is it possible.
And if new project is added from the front end ie(now the query will produce 4 rows but now in template i have created only three columns)
Is it possible to add a new column dynamically.
Can any one please guide me and tell me is there any example.
Thanks & regards

One more way,
create table #temp(Projectname varchar(10),Weeks varchar(10), Work int)
insert into #temp values('p1','w5',200)
insert into #temp values('p1','w6',300)
insert into #temp values('p1','w7',234)

insert into #temp values('p2','w6',987)
insert into #temp values('p3','w1',976)
insert into #temp values('p3','w2',231)
Select ProjectName,
Sum(Case when Weeks = 'W1' Then Work Else NULL End) W1,
Sum(Case when Weeks = 'W2' Then Work Else NULL End) W2,
Sum(Case when Weeks = 'W3' Then Work Else NULL End) W3,

Converting Rows into Column in Oracle 10g

Hi All,
I m using Oracle Version 10.1.0.2.0 - Production
I have requirement to convert rows into column wise as per the following:
My Query is:
WITH t
AS ( SELECT 'A' AS x, 100 AS y FROM DUAL
UNION ALL
SELECT 'B',200 FROM DUAL
SELECT X, Y
FROM t;
X Y
A 100
B 200
My Requirement is
A B
100 200
So any one could help me that how I resolve this.
Regards,
Prasanta

Dear frank,
Thanks for your support,.
It's working fine for static cases.If the first column is dynamic then how come i will resolve it.
Example:
Create table mytab (ID_C Varchar2(15),Value_N Number);
Records Population into MyTab table is dynamic.
Insert into mytab values('HO',5000);
Insert Into mytab values('PG1',2400);
Insert Into mytab values('PG2',3000);
Insert Into mytab values('PG3',800);
Commit;
SQL> Select * From MyTab;
IDC_ ValueN_
HO 5000
PG1 2400
PG2 3000
PG3 800
Then My expected result will be as follows
HO PG1 PG2 PG3
5000 2400 3000 800
Thanks and Regards,
Prasanta

How to convert rows to columns in sql server 2008

How to convert rows to columns in sql server 2008 using the GROUP BY function? (only one query allowed)

Lookup the Pivot transformation. From BOL:
The Pivot transformation makes a normalized data set into a less normalized
but more compact version by pivoting the input data on a column value. For
example, a normalized Orders data set that lists customer name, product, and quantity purchased typically has multiple rows for any customer who purchased multiple products, with each row for that customer showing order
details for a different product. By pivoting the data set on the product column, the Pivot transformation can output a data set with a
single row per customer. That single row lists all the purchases by the customer, with the product names shown as column names, and the quantity shown as a value in the product column. Because not every customer purchases every product, many columns may contain
null values.
When a dataset is pivoted, input columns perform different roles in the pivoting process. A column can participate in the following ways:
The column is passed through unchanged to the output. Because many input rows
can result only in one output row, the transformation copies only the first
input value for the column.
The column acts as the key or part of the key that identifies a set of
records.
The column defines the pivot. The values in this column are associated with
columns in the pivoted dataset.
The column contains values that are placed in the columns that the pivot
creates.

hi Sarma,
i visited to the link given by you & also reviewed the problems.but the question still in mind,with decode we can covert rows into columns but only where we have finite no of values in the row for eg. in deptno. we have just 4 types of values i.e. 10-40...
but in case we have more than 20 distinct values in row & we have to make 20 column name from those 20 row values then we need 20 decode statements which is a lengthy process..do you have some other alternative regarding this.

How to Convert Rows to Column in Query

Dear All,
I'm having problems in converting the data from rows into columns. Eg:
- item A sold on 01/01/07 = 5 kg
- item A sold on 10/01/07 = 5 kg
total item A sold in "JAN" = 10kg
- item A sold on 01/03/07 = 20 kg
total item A sold in "Mar" = 20kg
I did a query and it appear as below (in which I need the period as column)
Item Qty Period
A 10 2007-01
A 20 2007-03
The output I need is :
Item Jan Feb Mar
A 10 - 20
I've refer to the query posted in "Item History Query", even though I can get the column from Jan - Dec, but the total quantity for each month is not accurate. Please advise, and thanks for your time.
Cheers,
Serene

Hello Serene,
The Quantities will not be correct because you are using a Period Code in the Selection Criteria but it is not checked in the Select Statement.
But rewriting the code would cause duplicate entries for each item per months because of how the Group by clause works.
CHECK THIS
SELECT T1.ItemCode, T1.Dscription,
(SELECT SUM(QUANTITY) FROM INV1 WHERE MONTH(DOCDATE) = 1 AND ITEMCODE = T1.ItemCode AND DOCDATE >= T2.F_RefDate AND DOCDATE <= T_RefDate) AS 'JAN',
(SELECT SUM(QUANTITY) FROM INV1 WHERE MONTH(DOCDATE) = 2 AND ITEMCODE = T1.ItemCode AND DOCDATE >= T2.F_RefDate AND DOCDATE <= T_RefDate) AS 'FEB',
(SELECT SUM(QUANTITY) FROM INV1 WHERE MONTH(DOCDATE) = 3 AND ITEMCODE = T1.ItemCode AND DOCDATE >= T2.F_RefDate AND DOCDATE <= T_RefDate) AS 'MAR',
(SELECT SUM(QUANTITY) FROM INV1 WHERE MONTH(DOCDATE) = 4 AND ITEMCODE = T1.ItemCode AND DOCDATE >= T2.F_RefDate AND DOCDATE <= T_RefDate) AS 'APR',
(SELECT SUM(QUANTITY) FROM INV1 WHERE MONTH(DOCDATE) = 5 AND ITEMCODE = T1.ItemCode AND DOCDATE >= T2.F_RefDate AND DOCDATE <= T_RefDate) AS 'MAY',
(SELECT SUM(QUANTITY) FROM INV1 WHERE MONTH(DOCDATE) = 6 AND ITEMCODE = T1.ItemCode AND DOCDATE >= T2.F_RefDate AND DOCDATE <= T_RefDate) AS 'JUN',
(SELECT SUM(QUANTITY) FROM INV1 WHERE MONTH(DOCDATE) = 7 AND ITEMCODE = T1.ItemCode AND DOCDATE >= T2.F_RefDate AND DOCDATE <= T_RefDate) AS 'JUL',
(SELECT SUM(QUANTITY) FROM INV1 WHERE MONTH(DOCDATE) = 8 AND ITEMCODE = T1.ItemCode AND DOCDATE >= T2.F_RefDate AND DOCDATE <= T_RefDate) AS 'AUG',
(SELECT SUM(QUANTITY) FROM INV1 WHERE MONTH(DOCDATE) = 9 AND ITEMCODE = T1.ItemCode AND DOCDATE >= T2.F_RefDate AND DOCDATE <= T_RefDate) AS 'SEP',
(SELECT SUM(QUANTITY) FROM INV1 WHERE MONTH(DOCDATE) = 10 AND ITEMCODE = T1.ItemCode AND DOCDATE >= T2.F_RefDate AND DOCDATE <= T_RefDate) AS 'OCT',
(SELECT SUM(QUANTITY) FROM INV1 WHERE MONTH(DOCDATE) = 11 AND ITEMCODE = T1.ItemCode AND DOCDATE >= T2.F_RefDate AND DOCDATE <= T_RefDate) AS 'NOV',
(SELECT SUM(QUANTITY) FROM INV1 WHERE MONTH(DOCDATE) = 12 AND ITEMCODE = T1.ItemCode AND DOCDATE >= T2.F_RefDate AND DOCDATE <= T_RefDate) AS 'DEC',
(SELECT SUM(QUANTITY) FROM INV1 WHERE ITEMCODE = T1.ItemCode AND DOCDATE >= T2.F_RefDate AND DOCDATE <= T_RefDate) AS 'TOTAL'
FROM OINV T0 INNER JOIN INV1 T1 ON T0.DocEntry = T1.DocEntry INNER JOIN OFPR T2 ON T0.FinncPriod = T2.AbsEntry
WHERE T0.CardName ='[%A]' AND T2.Code >='[%1]' AND T2.Code <='[%2]'
GROUP BY T1.ItemCode, T1.Dscription, T2.F_RefDate, T2.T_RefDate
The Only way out of this is to declare Variable and Assign the F_RefDate and T_RefDate and then use the variables in the Select Statements.

How do I transpose all rows into columns like how excel does?
For example:
declare @t table (ProductID int, Type varchar(20), Name varchar(20), isAvailable bit)

union
select 2, 'Type1', 'Product2',0
