Oracle row to column transformation

RDBMS :10.2
Hi,
I have a query that composed of there tables and have joins in them. The final result query is giving is as folllow
ProductId ComProductId description
055X     035X     Ladies Companion
055X     055X     Adult Companion
112008     112009     Large Companion
112008     112008     Medium Companion
112009     112009     Medium Companion
112009     112008     Large Companion
I want to transform the output in following way, so every product may have its comProductID + Description in single row e.g. Product -ComProductId1 description1 ComProductId2 description2 .....
ProductId ComProductId description ComProductId description
055X     035X     Ladies Companion 055X     Adult Companion
112008     112009     Large Companion 112008     Medium Companion
Do we have any built in function or way to achieve this goal ?

thank you Hoek. it was really great to read. But as per post, i need to use "dynamic Pivot" but it is in 11g and i am using 10 g :(
Following query I am using to get results and that query I wan to transform
SELECT mainitem.productid as ProductId,
compitem.productid as ComProductId,
comp.header as description
FROM comp
JOIN item mainitem ON comp.Id = mainitem.id
JOIN item compitem ON comp.Companion = compitem.id;
this query produce following results
ProductId ComProductId description
055X 035X Ladies Companion
055X 055X Adult Companion
112008 112009 Large Companion
112008 112008 Medium Companion
112009 112009 Medium Companion
112009 112008 Large Companion
I want to transform the output in following way, so every product may have its comProductID + Description in single row e.g. Product -ComProductId1 description1 ComProductId2 description2 .....
ProductId ComProductId description ComProductId description
055X 035X Ladies Companion 055X Adult Companion
112008 112009 Large Companion 112008 Medium Companion

Oracle rows to columns/pivot function

Does anyone have any experience using the oracle pivot function? I have two tables:
Table1:Users
Username
jsmith
jjohnson
jbeck
Table2:Job Codes
Username,Job Code
jsmith,JC1
jsmith,JC2
jsmith,JC3
jbeck,JC2
I'm looking to formulate a query that will allow me to join the two tables and at the same time have the rows from table2 represented as columns (assuming a max of 3 job codes):
Username,JobCode1,JobCode2,JobCode3
jsmith,JC1,JC2,JC3
jbeck,JC2,,
It seems like pivot is the function I want to use for this but I can't seem to correlate the examples online back to what we're trying to do.

Hi,
Welcome to the forum!
Whenever you have a problem, please post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all tables involved, and also post the results you want from that data.
Explain, using specific examples, how you get those results from that data.
Always say which version of Oracle you're using.
See the forum FAQ {message:id=9360002}
Since I don;t have a version of your table, I'll use the scott.emp table.
I think you want something like this:
WITH     got_r_num     AS
     SELECT     job, ename
     ,     ROW_NUMBER () OVER ( PARTITION BY job
                               ORDER BY         ename
                       ) AS r_num
     FROM    scott.emp
SELECT       *
FROM       got_r_num
PIVOT       (    MIN (ename)
            FOR r_num IN ( 1      AS name_1
                             , 2 AS name_2
                   , 3 AS name_3
ORDER BY job
;This shows up to 3 names from each job
JOB       NAME_1     NAME_2     NAME_3
ANALYST   FORD       SCOTT
CLERK     ADAMS      JAMES      MILLER
MANAGER   BLAKE      CLARK      JONES
PRESIDENT KING
SALESMAN ALLEN      MARTIN     TURNERIf there are more than 3 rows with the same job, only the first 3 (in alphabetic order; that's what the analytic ORDER BY clause is doing) will be shown. For example, there's another SALESMAN named WARD who is not shown above.
This query requires Oracle 11.1 (or higher).
For other pivot techniques, including ones for earlier versions, see the forum FAQ {message:id=9360005}

Row to Column Transformation for Millions of records

Hi Members,
I need to transform data from two stage tables which has data in PIM structure (data stored as separate records ) to target table which has a flat structure (data stored in a single record). One of the stg tables has data volume of 45M and other has 5M records.The challenge I am seeing here is to transform such huge data into single table with considerable performance.What would be the ideal way to transform such huge data?Also can we have multiple programs running at the same time to achieve transformation for such huge data load quicker?
Just to add my Oracle Version is 10g.
Thanks

Still no version number, still no code, and no explain plan report.
Is there a better, faster way to do it?, I don't know ... how could I or anyone else as you've not told us what you are doing beyond the level of "my car won't start tell me why?"
This should help you understand the issue from my keyboard.

Row to Column transformation on an update form

I'm trying to create an updateable HTML-DB application that does the following. Any idea, the best way to do this?
Converts table rows into HTML-DB columns.
Create table INV_ORDERS
(Month date,
Beg_Inv number,
Planned_orders number
select * from INV_ORDERS;
Month Beg_Inv Planned_Orders
NOV-2005 10 20
DEC-2005 30 40
JAN-2006 50 60
How can I pivot it to be:
NOV-2005 DEC-2006 JAN-2006
Beg_Inv 10 30 50
Planned_Orders 20 40 60
The pivot numbers need to be updatable (via HTML-DB).
Thank you.

As it stands, your problem definition is quite "hard". Each column in the HTML DB tabular form belongs to a different physical row. You could try creating the tabular form off of a view that does the pivot and writing a INSTEAD OF trigger on that view, but it is not going to be easy.
But why?
What problem are you trying to solve, maybe we can suggest a different approach?

Need a query to do row to column transformation

Convert rows to Columns in Oracle

Hi,
The table like
Trx         Date
PO121 23/11/2008
PO122 24/11/2008
PO123 25/11/2008
I want to convert all the rows to columns like the below table
PO121    23/11/2008    PO122    24/11/2008       PO123     25/11/2008
Is it possible in Oracle ?

Like this
SQL> WITH T
2 AS
3 (
4     SELECT 'PO121 23/11/2008' VAL FROM DUAL
5     UNION ALL
6     SELECT 'PO122 24/11/2008' FROM DUAL
7     UNION ALL
8     SELECT 'PO123 25/11/2008' FROM DUAL
9 )
10 SELECT MAX(DECODE(RNO,1,VAL)) VAL1, MAX(DECODE(RNO,2,VAL)) VAL2, MAX(DECODE(RNO,3,VAL)) VAL3
11    FROM (SELECT ROW_NUMBER() OVER(ORDER BY VAL) RNO, VAL
12       FROM T)
13 /
VAL1             VAL2             VAL3
PO121 23/11/2008 PO122 24/11/2008 PO123 25/11/2008But beware the number of column must be known. without that you cant do it in a static SQL.

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

Row to Column XSL Transform in BLS

What am I missing?

Sparks,
Any reason you are not using the VerticalGrid Applet?
Did you specify any of the parameters required by the XSL, such as ColumnID and ValueID?
The XSL appears to only translate a single row node to a column....
Try using this XSL:

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

;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

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.

Map CdC op transform SEQUENCE and ROW oper column properties

I am using Map_cdc_op transform, for sequence column and row operation column properties, what fields should i choose?
My source table has the following columns:
RMID - primary key int
RMName - varchar
created_date datetime
Last_updated datetime
target table also has above 4 columns plus one rmLogID column with int data type. which is key column in target.
does map_cdc_op transform also take care of the surrogate key column id in target? which is "rmlogid".
thank you very much for the helpful info.

Suneer I am using SQL serverdatabase, this table is dragged to workspace as source:
RMID - primary key int
RMName - varchar
created_date datetime
Last_updated datetime
My task is to capture data changes from this table to target table, for that i a using Map_op_CDC transform, now under the properties SEQUENCE and ROW oper column what fields should i pic.I never used this transform before.
RMid is the primary key in source, rest teh of teh fields are changeable. i track created_dt and last_updated dates for that row.
Thanks a lot for the helpful info.

Dynamic rows to columns oracle 10g

Hi,
I'm using oracle 10g. I have a requiriement where I need to show rows to columns. I have read through many posts but I couldn't find what I wanted to solve. Lots of them are using decode, since they know the values in one column.
My table has name, value and date. I need to get values for each name at certain date (each distinct date needs to become column). I don't know the name beforehand.
Name, Value, Date
T1 100 06-27-2011 09:00:00
T2 100 06-27-2011 09:00:00
T1 200 06-27-2011 09:15:00
T2 150 06-27-2011 09:15:00
I would also need to use a date range. Someone can request date between 09:00:00 and 09:05:00 or 09:00:00 and 09:30:00 etc.
I need to print
Name, 06-27-2011 09:00:00, 06-27-2011 09:15:00
T1 100 200
T2 100 150
Appreciate any advice on this.

Oracle 10g Rows to column

Hi
I have folowing scenario. I am getting the result with some query like below :
STATE      DAY     AVG
NY        02/02     5
NY        02/03     10
NY        02/04     20
NY        02/05     15
IL        02/02     23
IL        02/03     34
IL        02/04     29
IL        02/05     9
FL        02/02     15
FL        02/03     8
FL        02/04     9
FL        02/05     10
and so on..Now I want to convert it from rows to column, but still want to keep STATE column group by :
so the result would be :
STATE   02/02   02/03   02/04   02/05
NY        5      10       20    15
IL        23     34       29    9
FL        15     8        9     10
and so on...I tried using pivot function, but it didnt work. is it even possible? or I will have to do it in code (.net c#) side.
Thanks

Transformation of Rows to Column in HANA

Hi All,
I have a requirement of converting rows to columns.
For Ex -

Hi Nakul,
There have the points you need to reach your goal, see what would be in SQL:
select
status_start_date,
sum(s1) as s_Initiated,
sum(s2) as s_cleared,
sum(s3) as s_scf_associated,
sum(s4) as s_scf_supervisor
from (
select status_start_date,count(*) as s1,0 as s2,0 as s3,0 as s4 from _sys_bic."Spend/AT_GES_CLAIMS_FLAG_DTLS"
where status_start_date between '2014-01-24' and '2014-01-30' and status='Initiated'
group by status_start_date
union all
select status_start_date,0 as s1,count(*) as s2,0 as s3,0 as s4 from _sys_bic."Spend/AT_GES_CLAIMS_FLAG_DTLS"
where status_start_date between '2014-01-24' and '2014-01-30' and status='Cleared'

group by status_start_date
union all
select status_start_date,0 as s1,0 as s2,0 as s3,count(*) as s4 from _sys_bic."Spend/AT_GES_CLAIMS_FLAG_DTLS"

Transpose of columns to rows (unpivoting) and not rows to columns

Hi,
I am right now using oracle 10g. I HAVE the following specification. Here I specified only 5 columns.
We have upto 200 columns.
TRANS_ID      PORTFILIO_NUM     TICKER          PRICE     NUM_SHARES ........................................
2     100     MO      25.00     100 ........................................
3     100     MCD          31.50     100 ........................................
I want the above to be transformed into the following output .
TRANS_ID TYPE VALUE
2 PORTFILIO_NUM 100
2 TICKER MO
2 PRICE 25.00
2 NUM_SHARES 100.
I don't want to use case/decode function by hard coding the 200 columns.
Can anyone provide me a good way (mostly dynamic way) of doing this?
I searched the whole forum and also other forums. Everywhere I could find
rows to columns / columns to rows where the column names have been hardcoded.
I want a dynamic way of doing it. Let me know if u need any other inputs.
DDL :
CREATE TABLE PORT_TRANS
TRANS_ID VARCHAR2(100 BYTE),
PORTFILIO_NUM VARCHAR2(100 BYTE),
TICKER VARCHAR2(100 BYTE),
PRICE VARCHAR2(100 BYTE),
NUM_SHARES VARCHAR2(100 BYTE)
INSERT INTO PORT_TRANS (TRANS_ID,PORTFILIO_NUM,TICKER,PRICE,NUM_SHARES)
VALUES('2','100','MO','25.00','100');
INSERT INTO PORT_TRANS (TRANS_ID,PORTFILIO_NUM,TICKER,PRICE,NUM_SHARES)
VALUES('3,'100','MCD','31.50','100');
COMMIT;
Thanks,
Priya.

Hi,
What you're trying to write is something like this:
WITH     cntr     AS
     SELECT     LEVEL     AS n
     FROM     dual
     CONNECT BY     LEVEL     <= 4
SELECT     p.trans_id
,     CASE
          WHEN c.n     <= 2
          THEN
               CASE     c.n
                    WHEN 1     THEN 'PORTFILIO_NUM'
                    WHEN 2     THEN 'TICKER'
               END
          ELSE
               CASE     c.n
                    WHEN 3     THEN 'PRICE'
                    WHEN 4     THEN 'NUM_SHARES'
               END
     END     AS type
,     CASE
          WHEN c.n     <= 2
          THEN
               CASE     c.n
                    WHEN 1     THEN p.PORTFILIO_NUM
                    WHEN 2     THEN p.TICKER
               END
          ELSE
               CASE     c.n
                    WHEN 3     THEN p.PRICE
                    WHEN 4     THEN p.NUM_SHARES
               END
     END     AS value
FROM          port_trans     p
CROSS JOIN     cntr          c
ORDER BY     p.trans_id
,          c.n
;I wrote this as if CASE could only handle 2 choices, rather than 128, just to show how to nest CASE expressions.
What you have to do is write the CASE expressions, based on the contents of all_tab_columns.
In your sample data, all of the columns are VARCHAR2 (another design flaw). If you have any columns of other types, use TO_CHAR to convert them to VARCHAR2; that is, the final code to be run will have something like:
...                    WHEN 4     THEN TO_CHAR (p.NUM_SHARES)If I had to do this, I might run several queries on all_tab_columns, each producing one script, containing just a fragment of the query.
To run the whole thing, I would hard-code a main query like this
WITH     cntr     AS
     SELECT     LEVEL     AS n
     FROM     dual
     CONNECT BY     LEVEL     <=
                    @num_columns.sql
SELECT     p.trans_id
,     CASE
          @type.sql
     END     AS type
,     CASE
          @value.sql
     END     AS value
FROM          port_trans     p
CROSS JOIN     cntr          c
ORDER BY     p.trans_id
,          c.n
;As with any coidng, start small and take baby steps. Maybe the first step would just be to write num_columns.sql, which just contains the number 4. When you can do that, hard-code the CONNECT BY query, calling num_columns.sql.
Good luck!

From rows to columns

Hi all, i was wondering if there is a way to transform rows to column using analytical function. i know you can use min or max function and group by but would like to know if the same can be accomplish using analytical function. i am using oracle 9i
sample data
WITH table1 AS
   SELECT 'AJD' id , 'BUNIT' code, 1000 myvalue FROM dual UNION all
   SELECT 'AJD' id , 'BCAT' code, 2000 myvalue FROM dual UNION all
   SELECT 'AJD' id , 'BLINE' code, 3000 myvalue FROM dual UNION all
   SELECT 'AJD' id , 'BCEN' code, 4000 myvalue FROM dual UNION ALL
   SELECT 'AAA' id , 'BUNIT' code, 5000 myvalue FROM dual UNION all
   SELECT 'AAA' id , 'BCAT' code, 6000 myvalue FROM dual UNION all
   SELECT 'AAA' id , 'BLINE' code, 7000 myvalue FROM dual UNION all
   SELECT 'AAA' id , 'BCEN' code, 8000 myvalue FROM dual
desire output

AAA    5000    6000   7000    8000
if this can be done using analytical function, please provide query if possible. thanks

Thanks for the sample data.
I'm not sure why you want to do this with analytic fiunctions instead of aggregates, it seems like a lot of effort for no gain, but this works on 9.2.0.8.0, and should work on other versions of 9i.
