Converting rows to columns using t-sql

Hi All,
I have a table with 3 columns, let say ID1 , ID2, Flag
My Source data looks like this..
ID1    ID2       Flag
1         1            0
1         2            0
1         3            0
2         7            0
2         8            1
2         9            0
4         5            0
Now My output should look like this..
ID1     Newcol1     NewFlag1     Newcol2     NewFlag2   Newcol3    NewFlag3
1           1                    0
2                   0                3
0
2           7                    0
    8                   1                9
0
4           5                    0
null             null            null              null
Basically I want to convert rows to columns and to get above output I need t-SQL query.
Thanks in advance

You can do it by this query:
declare @table table ( ID1 int, ID2 int, Flag int)
insert @table values ( 1,1,0 ),( 1,2,0 ),( 1,3,0 ),( 2,7,0 ),( 2,8,1 ),( 2,9,0 ),( 4,5,0 )
WITH cte1
AS ( SELECT Id1 ,
ROW_NUMBER() over (partition by ID1 order by ID1 ) as Sequence ,
ID2 ,
Flag
FROM @table
cte2
AS ( SELECT Id1 ,
ColumnTitle + LTRIM(RTRIM(STR(Sequence))) AS ColumnTitle ,
ColumnData
FROM cte1 UNPIVOT ( ColumnData FOR ColumnTitle IN ( [ID2], [Flag] ) ) AS UP
SELECT Id1 ,
[ID21] FirstID2 ,
[Flag1] FirstFlag ,
[ID22] SecondID2 ,
[Flag2] SecondFlag ,
[ID23] ThirdID2 ,
[Flag3] ThirdFlag
FROM cte2 PIVOT ( MAX(ColumnData) FOR ColumnTitle IN ( [ID21],
[Flag1],
[ID22],
[Flag2],
[ID23],
[Flag3] ) ) PV

Convert rows to columns using t-sql

Hi All,
My source data looks like this..
ID      Name    Rn

sql

to achieve this you need to have either 1. some unique key that can refer rn=1 and 2 for each person in each group or 2 . identity value column where, row number are enforce order of rn=1 and rn=2
Vinay''s solution works until you have do not have last name for one row but have some data for the same group id
like :
INSERT INTO #temp1(ID,Name,Rn) VALUES (1,'Sam',1)
INSERT INTO #temp1(ID,Name,Rn) VALUES (1,'John',2)
INSERT INTO #temp1(ID,Name,Rn) VALUES (1,'Greg',1)
INSERT INTO #temp1(ID,Name,Rn) VALUES (1,'Smith',2)
INSERT INTO #temp1(ID,Name,Rn) VALUES (1,'Aron',1)
INSERT INTO #temp1(ID,Name,Rn) VALUES (1,'newfirstname',1)
INSERT INTO #temp1(ID,Name,Rn) VALUES (1,'wronglastname',2)
INSERT INTO #temp1(ID,Name,Rn) VALUES (2,'Brad',1)
INSERT INTO #temp1(ID,Name,Rn) VALUES (2,'Kevin',2)
INSERT INTO #temp1(ID,Name,Rn) VALUES (2,'Alex',1)
INSERT INTO #temp1(ID,Name,Rn) VALUES (2,'Jeff',2)
this would work but as said you need some key to identify uniquely.
create table #Tmp (no int identity(1,1),ID int,Name varchar(20),Rn int)
insert into #Tmp
values
(1,'Sam',1),
(1,'John',2),
(1,'Greg',1),
(1,'Smith',2),
(1,'Aron',1),
(2,'Brad',1),
(2,'Kevin',2),
(2,'Alex',1),
(2,'Jeff',2)
Select distinct A.ID,A.Name,A.RN,B.NAme,B.Rn
from(
(select A.ID,A.Name,A.RN,A.no from #tmp A where A.rn=1) A FULL OUTER JOIN
(select A.ID,A.Name,A.RN,A.no from #tmp A where A.rn=2) B on a.ID=B.id and A.no=B.no-1)
drop table #tmp
Hope it Helps!!

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.

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 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
