i searched google and found PIVOT, CROSS JOIN etc but could not use those keyword properly.
Thanks in advance.
Note - My DB client version is 11g.
Since you have 11G, here's an alternative with the PIVOT clause.
First, set up test data with up to 10 rows:
CREATE TABLE T(P1,C1,C2,C3,C4,C5,C6,C7,C8,C9,C10) AS SELECT
1,1,2,3,4,5,6,7,8,9,10 FROM DUAL;
INSERT INTO T
WITH DATA AS (SELECT LEVEL*10 N FROM DUAL CONNECT BY LEVEL <= 9)
SELECT P1, C1+N, C2+N, C3+N, C4+N, C5+N, C6+N, C7+N, C8+N, C9+N, C10+N
FROM T, DATA;
INSERT INTO T
SELECT P1+1,C1,C2,C3,C4,C5,C6,C7,C8,C9,C10
FROM T
WHERE C1 <= 11;
select * from t order by p1,c1;
P1

Now the SELECT statement using PIVOT:

I would like to convert that into single column like below.

select 9,'Sales' from dual union all
select 3,'Mgmt' from dual

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

Converting multiple column rows into single column
Hi all Below is my requirement, can you anybody help me solve it. CREATE TABLE TYPE ( c1_type VARCHAR2 (10), c2_type VARCHAR2 (10), c3_type VARCHAR2 (10), c4_type VARCHAR2 (10), c5_type VARCHAR2 (10), c6_type VARCHAR2 (10), c7_type VARCHAR2 (10), c8_type VARCHAR2 (10), c9_type VARCHAR2 (10)); INSERT INTO TYPE VALUES ('Region_D', 'Region_E', 'Region_F', 'Region_D', 'Region_E', 'Region_D', 'Region_M', 'Region_D', 'Region_E'); commit; Acutal output on the below query select * from type; C1_TYPE C2_TYPE C3_TYPE C4_TYPE C5_TYPE C6_TYPE C7_TYPE C8_TYPE C9_TYPE Region_D Region_E Region_F Region_D Region_E Region_D Region_M Region_D Region_E Acutal i am expecting the below output,how to make it using query or using oracle built in function. Region_D Region_D Region_D Region_D Region_E Region_E Region_E Region_F Region_M
Hi,
So, you want to put the column values in alphabetic order, with the earliest value in c1_type and the last in c9_type, is that it?
The fact that you even want to do this says that this is a bad table design. If sorting the values makes sense, then putting them all in the same column on 9 different rows (rather than 9 different columns on 1 row) makes sense.
If you're stuck with the current design, then use SELECT ... UNPIVOT to put them on separate rows, then use the analytic ROW_NUMBER function to assign numbers 1-9 to each value, and finally use SELECT ... PIVOT to put them back into 1 row in that order. If you're not familiar with the built-in UNPIVOT and PIVOT features, look them up in the SQL Language manual, and see the forum FAQ:
https://forums.oracle.com/message/9362005
If you get stuck, post your best attempt (formatted), the exact results you want (formatted), and your Oracle version (e.g. 11.2.0.2.0).
Also, TYPE is an Oracle keyword, so it's not a good table name. Use something like location_type instead. -

thanks for responding quickly.
the link example seems not to work for me:
below is the information you have requested:Below is some of what I requested. The CREATE TABLE and INSERT statements seem to be missing.
1. duplicate values have no effect
2. list doesn't need any order
3. Version 10.2.0.5.0 For that, I recommend the user-defined aggregate function called STRING_AGG in the Oracle Base page, but called STRAGG by most of the people who use it. You have to copy and run about 60 lines of code from the Oracle Base page, or from AskTom one time, but once you have it installed, the job is as simple as
SELECT MIN (rnum) AS rnum -- ROWNUM isn't a good column name, since it's the same as a pseudo-column
, STRAGG (count_1) AS count_1_list
FROM table_x
;Hundreds of other jobs you have in the future will be just as easy, and you won't have to go through the installation process again.
Relevant information:
1. table columns : count_1
all rows should become a single row with ',' in between
example:
select * from t1;
output:
Rownum count_1
1 8217
2 6037
3 5368
4 5543
5 5232
Desired results :
Rownum count_1
1 8217, 6037, 5368, 5543, 5232
Edited by: 855161 on Dec 11, 2012 1:25 PMThe main problem with STRAGG is that it doesn't create a list in order. You said that's not an issue in this case, but if you ever do need output in order, then the best option in Oracle 10 is the SYS_CONNECT_BY_PATH technique. The main Oracle-Base page shows how to use SYS_CONNECT_BY_PATH in Oracle 9. Of course, that works in all later versions too, but in version 10 a simpler way, using CONNECT_BY_ISLEAF, became available. See the Oracle-Base Comments Page for the eaiser Oracle 10 technique. -
How to transpose rows into multiple columns using pivot table
I have 1 row containing 12 columns with value "JAN", "FEB", "MAR", "J-1","F-1","M-1","J-2","F-2","M-2","J-3","F-3","M-3"
I want to display as
JAN J-1 F-1 M-1
FEB J-2 F-2 M-2
MAR J-3 F-3 M-3
How do I achieve the above?Today you have only 3 months JAN, FEB, MAR. Is it always the same number of columns. What if there are more months added to this row?
Is your data really coming from relational source or some sort of text file?
There is a better way to do this in narrative view using HTML if your requirement is just to show them in multiple rows and do some calculations.
Go to Narrative View;
In prefix, use <html> <table>
In 'Narrative' text box add something like this
<tr> <td> @1 </td> <td> @4 </td> <td> @7 </td> </tr>
<tr> <td> @2 </td> <td> @5 </td> <td> @8 </td> </tr>
<tr> <td> @3 </td> <td> @6 </td> <td> @9 </td> </tr>
In Suffix, use </table> </html>
You can also add simple calculations like sum etc at the very bottom of these rows as grand totals.

Now i want to display rows data into columns. See the output i want. Exactly, I dont know how many rows are there for each ID. It may increase or decrease.
ID REL_NAME REL_RELATION REL_PHONE
1---kish_rel1--- wife--- 1111---kish_rel2--- sister--- 2222---kish_rel3--- brother--- 3333
2---ram_rel1--- brother--- 4444
Thanks in advance,
PalHi,
I have found this is useful. But it is static. It wont work if we dont know the maximum number of rows present when grouped by ID.
Is there any other solution, which will give correct values, if we dont know the row count when grouped by ID.
SELECT hrid,
MAX(case when seq=1 then rel_name end) AS "rel_name1",
MAX(case when seq=1 then rel_relation end) AS "rel_relation1",
MAX(case when seq=1 then rel_phone end) AS "rel_phone1",
MAX(case when seq=2 then rel_name end) AS "rel_name2",
MAX(case when seq=2 then rel_relation end) AS "rel_relation2",
MAX(case when seq=2 then rel_phone end) AS "rel_phone2",
MAX(case when seq=3 then rel_name end) AS "rel_name3",
MAX(case when seq=3 then rel_relation end) AS "rel_relation3",
MAX(case when seq=3 then rel_phone end) AS "rel_phone3",
MAX(case when seq=4 then rel_name end) AS "rel_name4",
MAX(case when seq=4 then rel_relation end) AS "rel_relation4",
MAX(case when seq=4 then rel_phone end) AS "rel_phone4"
FROM (SELECT hrid, rel_name, rel_relation, rel_phone, ROW_NUMBER() over(partition by hrid ORDER BY hrid) AS seq FROM address)
GROUP BY hrid
Thanks,

Convert rows to single column using t-sql
Hi All,
I have a table with 7 columns, et say..
ID ,PatientName,Date,Time,Room_Num ,Specialized, DoctorName
My source date looks like this..
ID PatientName Date Time Room_Num Specialized DoctorName
1 Sam 10/02/2010 10:00 4 Heart

Roby
1 Sam 12/22/2010 11:00 1 Heart
John
1 Sam 12/22/2010 11:00 1 Lungs
Harris
My out put should look like this..
ID PatientName Date DoctorName
1 Sam 10/02/2010 John,Harris ( Need to be in 1 row because - ID, PatientName, Date is same)
2 Jones 11/12/2011 Bob ( Need to show as it is due to no repeatition
of ID)
3 Jim 12/05/2001 Greg,Roby ( Need to be in 1 row because - ID, PatientName,
Date is same)
1 Sam 12/22/2010 John,Harris ( Need to be in 1 row because - ID, PatientName, Date is same)
I am using below query to get above results but I am getting wrong results..Need some help in tweaking the query...
SELECT DISTINCT ID ,PatientName , Date
,STUFF(( SELECT ',' + DoctorName
FROM SampleTable ST1
WHERE ST1.ID=ST2.ID
FOR XML PATH('')),1,1,' ') AS DoctorName
FROM SampleTable1 ST2
GROUP BY ID ,PatientName , Date
With above query I am getting results like this...
ID PatientName Date DoctorName
1 Sam 10/02/2010 John,Harris ,John,Harris ( here John,Harris are repeating twice because of 4th row)
2 Jones 11/12/2011 Bob
3 Jim 12/05/2001 Greg,Roby
1 Sam 12/22/2010 John,Harris ,John,Harris ( here John,Harris are repeating twice because of 1st row)
