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}

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

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 .....

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.

Dynamic SQL Pivoting(Converting Row to Columns)

Hi All,
I am using Oracle 9i (Oracle9i Enterprise Edition Release 9.2.0.1.0 - Production)
and also 10g version
I am facing difficulties to find out the logic for
converting the set of values in one of the columns into the column headings for the entire query.
create TABLE my_tab ( deptno VARCHAR2(5), job VARCHAR2(50), sal NUMBER);
insert into my_tab ( deptno,JOB, sal) values ( 10, 'ANALYST', 23000);
insert into my_tab ( deptno,JOB, sal) values ( 10, 'SALESMAN', 1500);
insert into my_tab ( deptno,JOB, sal) values ( 10, 'CLERK', 3550);
insert into my_tab ( deptno,JOB, sal) values ( 20, 'SALESMAN', 700);
insert into my_tab ( deptno,JOB, sal) values ( 20, 'ANALYST', 4200);
insert into my_tab ( deptno,JOB, sal) values ( 30, 'SALESMAN', 5600);
insert into my_tab ( deptno,JOB, sal) values ( 30, 'CLERK', 12000);
insert into my_tab ( deptno,JOB, sal) values ( 30, 'ANALYST', 19000);
COMMIT;
SELECT * FROM my_tab
DEPTNO ______ JOB ________ SAL
10 ______ ANALYST ________ 23000
10 ______ SALESMAN     ________     1500
10     _______ CLERK     ________     3550
20     _______     SALESMAN ________     700
20     _______     ANALYST     ________ 4200
30     _______     SALESMAN ________     5600
30     _______     CLERK     _______          12000
30     _______ ANALYST     _______     19000
--And I wish to convert it into this structure:
DEPTNO ________ ANALYST ________ SALESMAN _________ CLERK
10      ________     23000 ________     1500     _________     3550
20     ________ 4200 ________     700     _________     NULL
30     ________ 19000 ________     5600     _________     12000
It may be dynamic. i.e Later i inserted more two records into My_tab.
insert into my_tab ( deptno,JOB, sal) values ( 20, 'CLERK', 3400);
insert into my_tab ( deptno,JOB, sal) values ( 30, 'MANAGER', 48000);
So it should be dynamic.
output is like this.
DEPTNO ________ ANALYST ______ SALESMAN ______ CLERK ______ MANAMGER
10           ________ 23000     ______ 1500     ______ 3550     ______     NULL
20          ________ 4200     ______ 700     ______ 3400     ______     NULL
30          ________ 19000     ______ 5600     ______ 12000     ______     48000
Please help me regarding this.

Hi, Prasanta,
Displaying one column from many rows as many columns on one row is called Pivoting . The following thread shows the basics of how to pivot:
Help for a query to add columns
That example uses the aggregate COUNT function; you'll want SUM (or possibly MIN or MAX) instead.
Getting a dynamic number of columns requires Dynamic SQL . As a simpler alternative to pivoting and dynamic SQL, you might consider String Aggregation , where you concatenate a column from many rows into one big string, to be displayed on one row.
See the following thread for more about string aggregation and other options on pivoting into a variable number of columns:

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

Navigation on row and column total in pivot report

Hi All,
I have created a pivot report with 2 dimension columns and one measure and defined row and column total. Now, users wants to have a navigation report on the row/column total so that once he clicks on total value, he can see the detail report. While doing this, he also wants to pass on the 2 dimension column values to detail report.
Is there any workaround for this?
Thanks in advance.

use a formula column/row. use RANK function in that. (e.g. Rank([A], asc) will sort the rows based on column A values in ascending order)
you can use this rank in your heading.
But frankly this is not so easy. You have to do it in a very intelligent way, so that rank gives you column number/row number any how.
Have a try and let see if you find a appropriate solution.
Regards,
Rahul

How to convert rows into columns with decode function

Need help with Pivoting rows to columns

Hi,
I need help with pivoting rows to columns. I know there are other posts regarding this, but my requirement is more complex and harder. So, please give me a solution for this.
There are two tables say Table 1 and Table 2.
Table1
name address email identifier
x e g 1
f s d 2
h e n 3
k l b 4
Table2
identifier TRno zno bzid
1 T11 z11 b11
1 T12 z12 b12
1 T13 z13 b13
2 T21 z21 b21
2 T22 z22 b22
As you can see the identifier is the column that we use to map the two tables. The output should be like below
output
name address email identifier TRno1 zno1 bzid1 TRno2 zno2 bzid2 TRno3 zno3 bzid3
x e g 1 T11 z11 b11 T12 z12 b12 T13 z13 b13
f s d 2 T21 z21 b21 t22 z22 b22
Also we do not know exactly how many TRno's, zno's, etc each value in the identifier will have. There may be only 1 TRNO, zno and bzid, or there may be four.
All the values must be in separate columns, and not be just comma delimitted. There are also other conditions that i have to add to restrict the data.
So, can you please tell me what is should use to get the data in the required format? We are using Oracle 10g. Please let me know if u need any more information

Something like this ?

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.

Pivot function in Oracle 10g???

Hello everybody,
at the beginning of the week I had a simple problem (I thought that...), but now after trying and trying, I can't find a solution for it. First of all I'm working on Oracle 10g with the version 10.2.0.4.0. I can't change the version, it's standard in the whole company...
At the beginning I have a table like the following one, but please note, that the compartment, the type and the amount are flexible and can change at any time:
comp type amount
a1 6280 10
a2 6280 20
a2 4810 15
a2 1147 12
a3 6280 33
Now I want the table to look like this:
a1 a2 a3
1147 0 12 0
4810 0 15 0
6280 10 20 33
A simple question in Excel for example, I just use the pivot function and have it fixed within 10seconds. But how can I do sth. like this in Oracle with simple SQL? Or it can be PL/SQL too, cause I will use this in an APEX application.
Can you please give me a hint or a solution? But as stated before a1, a2, a3 are just examples it is possible that tomorrow a4, a5 and so on are coming. If it is necessary I can also create additional tables and views of course!
Thanks for your help!
Regards
hoge

Hi Hoge!
Here is your solution:
SELECT TYPE,
       sum(a1) AS a1,
       sum(a2) AS a2,
       sum(a3) AS a3
FROM (SELECT TYPE,
               decode(comp, 'a1', amount, 0) AS a1,
               decode(comp, 'a2', amount, 0) AS a2,
               decode(comp, 'a3', amount, 0) AS a3
          FROM test)
GROUP BY TYPE
ORDER BY TYPE; And here is my test case setup:
CREATE TABLE test
    (comp VARCHAR2(255),
     TYPE NUMBER,
     amount NUMBER);
INSERT INTO test(comp, TYPE, amount) VALUES('a1', 6280, 10);
INSERT INTO test(comp, TYPE, amount) VALUES('a2', 6280, 20);
INSERT INTO test(comp, TYPE, amount) VALUES('a2', 4810, 15);
INSERT INTO test(comp, TYPE, amount) VALUES('a2', 1147, 12);
INSERT INTO test(comp, TYPE, amount) VALUES('a3', 6280, 33);

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

Pivot Table Row and Column extension OBIEE 11g

Hi,
I have pivot view report, I have 3 columns,
1) User Name
2) Date
3) Login Count
User Name will be row(Vertical)
Date will be Column heading (Horizontal)
Login Count Measures
So I will get login Count of user wrt date.
Now When I give Wide range of filter i.e, from 1st Jan 2010 to 31st Dec 2010.
There is increase in row also column, when it reaches certain extent it gives error as *'Exceeded configured maximum number of allowed input records.'*
How to change the limit? or there is any fix?
Thanks,
Satheesh

Hi,
I have also faced the same issue, i have solved by changing DefaultRowsDisplayed count in instance config file.
<Views>
<pivot table>
<DefaultRowsDisplayed>75</DefaultRowsDisplayed>
<pivot table>
</Views>
Paste that code (which i mentioned in my last post) in instanceconfig.xml before these tags
</ServerInstance>
</WebConfig>
But remember you need to restart the presentation service once this is done....
Thanks
