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

Pivoting rows into columns in Oracle 10g
Hi,
I want to pivot rows into column in some optimal way.
I don't want to go with the DECODE option as the number of columns can be more than 200.
i have also tried the transpose logic which is making the pl/sql block too huge.
can i directly query the database for the desired output instead of storing the data into some arrays and displaying rows as columns?Hi,
Here's a dynamic way to do this is Oracle 10, using theSQL*Plus @ command to handle the dynamic parts.
First, let's see how we would do this using a static query:
WITH col_cntr AS
SELECT column_name
FROM all_tab_columns
WHERE owner = 'FKULASH'
AND table_name = 'TEST_EMP'
AND column_name NOT IN ('EMP_ID', 'TYPE_VAL')
, unpivoted_data AS
SELECT e.type_val
, c.column_name
, CASE c.column_name
WHEN 'X_AMT' THEN x_amt -- ***** Dynamic section 1 *****
WHEN 'Y_AMT' THEN y_amt -- ***** Dynamic section 1 *****
WHEN 'Z_AMT' THEN z_amt -- ***** Dynamic section 1 *****
END AS v
FROM test_emp e
CROSS JOIN col_cntr c
SELECT column_name AS type_val
, SUM (CASE WHEN type_val = 'Q1' THEN v ELSE 0 END) AS q1 -- ***** Dynamic section 2 *****
, SUM (CASE WHEN type_val = 'Q2' THEN v ELSE 0 END) AS q2 -- ***** Dynamic section 2 *****
, SUM (CASE WHEN type_val = 'Q3' THEN v ELSE 0 END) AS q3 -- ***** Dynamic section 2 *****
, SUM (CASE WHEN type_val = 'Q4' THEN v ELSE 0 END) AS q4 -- ***** Dynamic section 2 *****
FROM unpivoted_data
GROUP BY column_name
ORDER BY column_name
;Column names are hard-coded in two places:
(1) in the sub-query unpivoted_data, we had to know that there were 3 columns to be unpivoted, and that they were called x_amt, y_amt and z_amt. You want to derive all of that from all_tab_columns.
(2) in the main query, we had to know that there would be 4 pivoted columns in the rsult set, and that they would be called q1, q2, q3 and q4. You want to derive all that from the data actually in test_emp.
Instead of hard-coding those 2 dynamic sections, have Preliminary Queries write them for you, a split second before you run the main query, by running this script:
-- Before writing sub-scripts, turn off features designed for human readers
SET FEEDBACK OFF
SET PAGESIZE 0
PROMPT ***** Preliminary Query 1 *****
SPOOL c:\temp\sub_script_1.sql
SELECT ' WHEN '''
|| column_name
|| ''' THEN '
|| LOWER (column_name) AS txt
FROM all_tab_columns
WHERE owner = 'FKULASH'
AND table_name = 'TEST_EMP'
AND column_name NOT IN ('EMP_ID', 'TYPE_VAL')
ORDER BY column_name
SPOOL OFF
PROMPT ***** Preliminary Query 2 *****
SPOOL c:\temp\sub_script_2.sql
SELECT DISTINCT ', SUM (CASE WHEN type_val = '''
|| type_val
|| ''' THEN v ELSE 0 END) AS '
|| LOWER (type_val) AS txt
FROM test_emp
ORDER BY txt
SPOOL OFF
-- After writing sub-scripts, turn on features designed for human readers
SET FEEDBACK 5
SET PAGESIZE 50
-- Main Query:
WITH col_cntr AS
SELECT column_name
FROM all_tab_columns
WHERE owner = 'FKULASH'
AND table_name = 'TEST_EMP'
AND column_name NOT IN ('EMP_ID', 'TYPE_VAL')
, unpivoted_data AS
SELECT e.type_val
, c.column_name
, CASE c.column_name
@c:\temp\sub_script_1
END AS v
FROM test_emp e
CROSS JOIN col_cntr c
SELECT column_name AS type_val
@c:\temp\sub_script_2
FROM unpivoted_data
GROUP BY column_name
ORDER BY column_name
;As you can see, the main query looks exactly like the static query, except that the two dynamic sections have been replaced by sub-scripts. These 2 sub-scripts are written by 2 prelimiary queries, right before the main query.
As others have said, the fact that you're asking this question hints at a poor table design. Perhaps the table should be permanently stored in a form pretty much like unpivoted_data, above. When you need to display it with columns x_amt, y_amt, ..., then pivot it, using GROUP BY type_col. When you need to display it with columns q1, q2, ..., then pivot it using GROUP BY column_name. -

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

it will connect to the default SID, there's no such thing as a default SID, what do you mean?
But what if there are more that one SID available & I
want to connect to SID other than the default SID.just specify the desired SID prior starting rman.
more over the same string is working with 9i but not
with 10G.maybe due to a bug?
to summarize, you have two options it you would like to start up the instance:
either you specify the SID prior starting rman and use os authentication
or
you register the instance statically and use oracle authentication.

If you want the number of columns in the output to depend on the data in the table, then you have to use dynamic SQL, more or less like you did. The number of columns in a query has to be specified when the query is compiled. You can't compile something today that figures out how many distinct values you will have, and therefore how many columns you will need, tomorrow or next month.
See the following thread for several ways to deal with a dynamic numebr of columns
Re: Report count and sum from many rows into many columns
String aggregation is especially useful. -
This are the 4 columns, names of this columns are defined below the table.
01-B1 110854 800 80.02
01-A1 110852 200 20.02
01-A1 110852 600 60.02
01-A1 110852 800 80.02

01-C1 110855 800 80.02
FIRST COLUMN :MAT_NUMBER
2> REF_NUMBER
3>SCALE_QTY
4>SCALE_RATE.
NOW I WANT THE DATA SHOULD BE LIKE
FOR EXAMPLE TAKE THE MAT_NUMBER AS '01-A1' ,AND THIS HAS THREE ROWS.
OK.
THEN IN MY RESULTANT QUERY SHOULD BE ABLE TO GET LIKE THIS .
MAT_NUMBER------REF_NUMBER------SCALE_QTY------SCALE_QTY_RATE----SCALE_QTY2-----SCALE_QTY_RATE2---SCALE_QTY3----SCALE_QTY_RATE3
01-A1------------------110852---------------200------------------20.2--------------------------600---------------60.02------------------------800-----------------------80.02
-SCALE_QTY2-----SCALE_QTY_RATE2---SCALE_QTY3----SCALE_QTY_RATE3 THIS COLUMNS SHOULD BE A DYNAMIC .I.E IF '01-A1' HAS 3 ROWS
THEN IN RESULT THERE SHOULD BE A 3 NEW COLUMNS.
THREE ROWS OF 01-A1 SHOULD BE CONVERTED TO SINGLE ROW WITH 3 NEW COLUMNS.
MY DB VERSION :Oracle Database 10g Enterprise Edition Release 10.2.0.4.0
