Rows to columns convert

Hi,
I have one table as
CREATE TABLE BIPDBA.BIP_EXPORT_REQT_PARAM
EXPORT_REQT_ID NUMBER NOT NULL,
SN NUMBER NOT NULL,
EXPORT_REQT_PARAM_NAME VARCHAR2(100 CHAR) NOT NULL,
EXPORT_REQT_PARAM_VAL VARCHAR2(255 CHAR) NOT NULL
);Now I am storing the value as for every Parameter, for that Export_Reqt_ID
For example
EXPORT_REQT_ID     SN     EXPORT_REQT_PARAM_NAME     EXPORT_REQT_PARAM_VAL
1                      1     A                                             3232
1                      2     B                                             3233
1                      3     C                                             3234
1                      4     D                                             3235
1                      5     E                                             3236Now, I have to store the value of EXPORT_REQT_PARAM_VAL in variable names in one select query.
Select Value(EXPORT_REQT_PARAM_VAL) into Var_A,Var_B,Var_C,Var_D,Var_E from <table_name> where EXPORT_REQT_ID = 1 order by SNOrder by I have used to store the value in one sequence and it should go in appropriate variable.

Do you mean like this?
select max(decode,sn,1,export_reqt_param_val)
      ,max(decode,sn,2,export_reqt_param_val)
      ,max(decode,sn,3,export_reqt_param_val)
      ,max(decode,sn,4,export_reqt_param_val)
      ,max(decode,sn,5,export_reqt_param_val)
into var_a, var_b, var_c, var_d, var_e
from tablename
where export_reqt_id = 1

Hi, how can i break the value for a row and column once i have converted the image to the array???????

Hi, I would like to know how can i break the value for a row and column once i have converted the image to the array. I wanted to make some modification on the element of the array at a certain position. how can i do that?
At the moment (as per attachhment), the value of the new row and column will be inserted by the user. But now, I want to do some coding that will automatically insert the new value of the row and the column ( I will use the formula node for the programming). But the question now, I don't know how to split the row and the column. Is it the value of i in the 'for loop'? I've tried to link the 'i' to the input of the 'replace subset array icon' , but i'm unable to do it as i got some error.
Please help me!
For your information, I'm using LABView 7.0.

Hi,
Thanks for your reply.Sorry for the confusion.
I manage to change the array element by changing the row and column value. But, what i want is to allow the program to change the array element at a specified row and column value, where the new value is generated automatically by the program.
Atatched is the diagram. I've detailed out the program . you may refer to the comments in the formula node. There are 2 arrays going into the loop. If a >3, then the program will switch to b, where if b =0, then the program will check on the value of the next element which is in the same row with b but in the next column. But if b =45, another set of checking will be done at a dufferent value of row and column.
I hope that I have made the problem clear. Sorry if it is still confusing.
Hope you can help me. Thank you!!!!

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

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

My sourcec is containing 25 miliion records, and if i execute the query, it is getting hanged. Can someone help me how can i write a fine tuned query by using analytical function

How about this?

Converting from rows to columns

Converting Rows to Columns
We have one business requirment where they want to convert rows to columns. The data we are talking about is 2-3 TB of data. Data looks something in this format.
Table Structure
Date_1 Unit_Number Data_ID Data_Value
2013-01-02 00:00:00 100013 123 671
2013-01-02 00:00:00 100014 131 771
2013-01-02 00:00:00 100015 281 812
2013-01-02 00:00:00 100016 712 979
2013-01-02 00:00:00 100017 715 719
Pivoted table
Date_1 RY XY HJ KD IK GH HH KK TK RT ...
2013-01-02 00:00:00 671 771 812 979 719 979 719 980 799 79
2013-01-02 00:10:00 671 771 812 979 719 979 719 980 799 79
and so on
We are pivoting this data using query and creating view using query something like below
select a.date_1 date_1 a.unit_number system_number,
max(CASE WHEN a.data_id= 123 then a.DATA_Value END) RY,
max(CASE WHEN a.data_id= 281 then a.DATA_Value END) XY,
max(CASE WHEN a.data_id=712 then a.DATA_Value END) HJ,
max(CASE WHEN a.data_id=715 then a.DATA_Value END) KD,
max(CASE WHEN a.data_id=666 then a.DATA_Value END) IK,
max(CASE WHEN a.data_id=231 then a.DATA_Value END) GH,
max(CASE WHEN a.data_id=881 then a.DATA_Value END) HH,
max(CASE WHEN a.data_id=734 then a.DATA_Value END) KK,
max(CASE WHEN a.data_id=734 then a.DATA_Value END) TK,
max(CASE WHEN a.data_id=724 then a.DATA_Value END) TK,
from FROM table_name group by 1,2
We also tried pivot clause but still no major improvement in performance.
There are about 40 such rows that we are trying to convert into columns. We created indexes, Primary, Secondary and referencial ones to tune this overall query. Also added paritions, We find this conversion works fine for smaller query, however for larger set of data we get high CPU and IO and also often runs into spool error. The data set we are runing on this query are about 3-4 TB. There is another table where we have about 100 rows which we need to convert into one row and again size goes to 4-5 TB
Questions I have
1) Is there better way to convert columns to Rows?
2) What options can be use to reduce CPU, IO and Spool error?
3) Does Orage 11g datawarehouse any feature which will hellp us here
4) Any other appproach or design suggested here that will help us?
This design is pushed by our business due to flexibility this design offers and we are runing into performance and we are trying to make this work without impacting CPU, Spool and IO
Any suggestions would help us here, thanks for reading this

;When you run the two different (but very similar) to get the two times, you have two different WHERE clauses. You can combine those two similar queries into one, but whatever WHERE clause you have will apply to the whole query. Whenever you wish you could apply a WHERE clause just to one column, think of CASE instead.

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

Converting key figures from rows to column using DSO and start routine

Hi SDNer:
I need some help to convert key figures from rows to column.
The source is DSO 1 and I am thinking about writing ABAP in the start routine to do the conversion. The target is DSO2.
Below is the more detail information with example. Basically, for each record in DSO 1 I need to create 3 records (because there are 3 KF's) and output to DSO2.
I would really appreciate some help on this.Thank you.
Tony
DSO 1 data format (SOURCE)
Period   ID   KF1 KF2 KF3
200702 100 300 200   750
Output to DSO 2 (TARGET)
Period   ID    KF LABEL
200702 100 300 KF1
200702 100 200 KF2
200702 100 750 KF3

This is the code in BI 7.0.
u need to put a field "Label" in DSO1. u dont need to populate this in DSO1 but it helps the code to populate the field in DSO2.
DATA: wa_result TYPE _ty_s_sc_1,
t_result TYPE STANDARD TABLE OF _ty_s_sc_1.
DATA:counter(2) TYPE n.
LOOP AT SOURCE_PACKAGE INTO wa_result.
counter =0.
while counter < 3 .
wa_result- Period = wa_result-Period.
wa_result- ID = wa_result-ID.
if counter = 0.
wa_result- KF1 = wa_result-KF1.
wa_result- Label = 'KF1'.
elseif counter = 1.
wa_result- KF1 = wa_result-KF2.
wa_result- Label = 'KF2'.
else.
wa_result- KF1 = wa_result-KF3.
wa_result- Label = 'KF3'.
endif.
APPEND wa_result TO t_result.
counter = counter+1.
endwhile.
endloop.
CLEAR: SOURCE_PACKAGE,wa_result.
LOOP AT t_result INTO wa_result.
APPEND wa_result TO SOURCE_PACKAGE.
ENDLOOP.

Hi Pavan,
Thanks for the prompt reply.
The link seems to be of not relevant to my question.
My question is to clearly transpose the rows to columns and vice versa without any changes to data.
Regards,
993012I do not see any modification to the data in the Link posted by Pavan. Anyways, One catch with Transposing the Rows is, you need to know the Number of Columns you need to project.
With Static SQL, there is no way to do so. Hence, you will need PL/SQL with Execute Immediate/Dynamic SQL.
See demostration by Tom Kyte on Dynamic Pivots to have a look at the example and adapt to your situation.
Although, I will debate on the need to do it in SQL. Because what you are upto is a part of Reporting and there are many reporting Tools which will have this functionality in-built. SQL, ideally should not be used for reporting purposes. It sole purpose it to store and pass the data to be rendered by Client Software i.e. Java or Third Party tools.
