Row to Column Conversion Question
Hi All,
Could you please help on this sql query statement:
SELECT BENEFIT FROM TEST_T ;
BENEFIT
QO,1G,1U,1W
Out Put Needed like this
BENEFIT
QO
1G
1U
1W
Thanks,
Hi,
As I said, it depends on your data, your requirements and your version.
REGEXP_COUNT was new in Oracle 11.1. Since you're using an earlier version, you can see how many comma-delimited sub-strings you have by seeing how much shorter the string gets if you remove all the commas:
1 + LENGTH (benefit)
- LENGTH (REPLACE (benefit, ','))
This assumes you don't have data with mutiple consecutive commas such as 'AB,,,,CD', but it might not cause any terrible results even if you do.
The way I used CONNECT BY won't work in Oracle 10, either.
Now I know everything I need to know about your Oracle version, but I don't know anything about your data or your requirements. Do you want me to spend my time writing solutions that assume things about your data and your requirments, so you can spend your time trying them only to see that they don't do what you need?
Explain what your data is like. Do you have a fixed number of comma-delimited parts (e.g., always 4 parts). If not, do you have an upper bound (e.g., never more than 10 parts)? Can you have multiple consecutive commas?
Explain what you need to get from that data. Will you always be splitting one string into parts, as in the example you posted, or will you need to split multiple stings in the same query? Will the correct results ever contain NULL?
Post a little sample data (CREATE TABLE and INSERT statements), showing all special cases you need to handle. Post the results you want from that data.

Hi,
i am having following table
SELECT* FROM Col_to_row;
output is:
A B C
X Y Z
1 2 3
i want to write query for below output, need to convert row into column for n number of rows for example i have taken only 3 rows:
A X 1
B Y 2
C Z 3Three things to notice in this solution:
1) I am ordering by the original column name. You may want to order by something else.
2) When pivoting, you must indicate the name, number and datatype of the columns, so if there is a fourth line of input you have to add a column to the query.
3) This works on Oracle 11GR1 and above. Next time, be sure to indicate your Oracle version from the start.create table COL_TO_ROW(C1, C2, C3) as select
'A', 'B', 'C' from DUAL union all select
'X', 'Y', 'Z' from DUAL union all select
'1', '2', '3' from dual;
select * from (select rownum rn, a.* from COL_TO_ROW a)
UNPIVOT(VAL for COL in(C1, C2, C3))
PIVOT(max(VAL) for RN in (1,2,3))
order by col;
COL 1 2 3
C1 A X 1
C2 B Y 2
C3 C Z 3 -
Row break + column header Question
I've got two question i can't find out by myself.
Question 1:
I use a row break on the first column of my report. That workd correctly. But how do i get a line or a empety row after the break? I prefer a line...
Question 2:
I want to have an extra header above some columns. how to create that. A example:
extra header 1 extra header 2
column1 column2 column3 column4 column5 column6 column7
hope someone can help me with this... tnx in advancedHi,
For your second question, you could create a custom template and put in the additional headers in there, under the 'Before Column Heading' section. I have done this with one of my reports where I simply copied the standard template and changed it to include the header information. This is an example of what I have in the Before Column Heading section for my custom template.
<tr><th class="t18ReportHeader"#ALIGNMENT# colspan="4" style="font-weight:bold;text-align:center;">Progress Data </th></tr>
<tr><th class="t18ReportHeader"#ALIGNMENT#> </th>
<th class="t18ReportHeader"#ALIGNMENT# style="font-weight:bold;text-align:center;" colspan="4"> Header 1 </th>
<th class="t18ReportHeader"#ALIGNMENT# colspan="5" style="font-weight:bold;text-align:center"> Header 2 </th>
<th class="t18ReportHeader"#ALIGNMENT# colspan="4" style="font-weight:bold; text-align:center"> Header 3</th>

Rows to Column Conversion in ABAP
Hello guys,
I wanted to create a report in which I need to convert rows in to column.
e.g.
I have a itab_col which contains my column header as follows.
itab_col-plant itab_col-name
1000 Plant A
2000 Plant B
3000 Plant C
I have a itab_data which contains my data as follows .
itab_data-date itab_data-qty itab_data-plant
01.06.2006 10 1000
01.06.2006 20 1000
01.06.2006 50 2000
02.06.2006 20 3000
I need to print the report as follows
Date Plant A Plant B Plant C
01.06.2006 30 50 0
02.06.2006 0 0 20
Could you tell me how I can do it in abap.Hi,
first create table with following attribute.
table_row_to_column
1. date
2. Plant A
3. Plant B
4. Plant C.
.............D E F ..number of plant possible.
Sum Up The data
01.06.2006 10 1000
01.06.2006 20 1000
01.06.2006 50 2000

01.06.2006 30 1000
01.06.2006 50 2000
02.06.2006 20 3000
to new data_table_sum_value
<b>for that u have to</b>
1) Sort the table date & plant.
2) sum up records for similar plant based on date
<b>Convert rows in to column.</b>
loop at data_table_sum_value.
case data_table_sum_value-plant.
when 1000.
table_row_to_column-plant_A = data_table_sum_value-qnty.

Row to column conversion during excel download
Dear Experts,
I have an internal table with one column.
It has some entries say ten.
I want this ten rows of entries to be displayed in the excel sheet as a single row. It means each row entry of the internal table should fit in to each cell.
Is there any possibility with GUI_DOWNLOAD FM to do this?
If not, then how could i do that?
Please let me know its urgent.
Regards,

i m not aware of whether it can be done through FM 'GUI_DOWNLOAD' but i have one sugeestion.
You can first transpose your internal table and then download it.

Row to column conversion in large result set
I need to get the differnt levels of alerts for each user, with the total alert counts and counts for each type of alert.
SELECT COUNT(*) TOTAL,
u.name,
d.deptname,
COUNT(CASE WHEN al.severity = 5 THEN 1 END) INDETERMINATE,
COUNT(CASE WHEN al.severity = 4 THEN 1 END) WARNING,
COUNT(CASE WHEN al.severity = 3 THEN 1 END) MINOR,
COUNT(CASE WHEN al.severity = 2 THEN 1 END) MAJOR,
COUNT(CASE WHEN al.severity = 1 THEN 1 END) CRITICAL
FROM alerts al, user u, dept d
WHERE al.userid = u.userid
AND u.deptid = d.deptid
AND al.time = sysdate - 4/24
AND al.time <= sysdate
GROUP BY u.name, d.deptname This might be inefficient especially when the amount of data is huge and potentially you could be looking at millions of rows in a given interval. So I was thinking of grouping by severity, which would eliminate the CASE statements, but then the problem on group by is that I get it as a rows instead of columns.
Would anyone have a suggestion as to do it effeciently especially one that has millions of rows? Thanks.I guess eventually we are probably going to move towards that, but using a staright forward query is the immediate solution and any help on that would be great. Thanks.

Reg:Row to column conversion
Hi All,
I will give string three string values in a single variable like CNTNS_VAL_STR = test,value,small
but i need result like
test
value
small
Please help to reslove the one
thanks,Your requirement isn't very clear anymore.
Please post a small testcase, like I did below, assuming you're looking for a way to query column values based on an input string:
SQL> create table t as
2 select 1 rn,'A' descr from dual union
3 select 2,'B' from dual union
4 select 3,'C' from dual union
5 select 4,'Q' from dual union
6 select 5,'X' from dual;
Table created.
SQL> select * from t;
RN D
1 A
2 B
3 C
4 Q
5 X
5 rows selected.
SQL> create or replace function str2tbl( p_str in varchar2, p_delim in varchar2 default ',' )
2 return sys.odcivarchar2list
3 pipelined
4 as
5 l_str long default p_str || p_delim;
6 l_n number;
7 begin
8 loop
9 l_n := instr( l_str, p_delim );
10 exit when (nvl(l_n,0) = 0);
11 pipe row( ltrim(rtrim(substr(l_str,1,l_n-1))) );
12 l_str := substr( l_str, l_n+1 );
13 end loop;
14 return;
15 end;
16 /
Function created.
SQL> select *
2 from t
3 where descr in ( select column_value
4 from table(str2tbl('A,B,C'))
5 );
RN D
1 A
2 B
3 C
3 rows selected.
So, I more or less 'joined' a table to a pipelined function (no cursor needed) based on an input string.
If you search for 'str2tbl' on http://asktom.oracle.com then you'll find many more examples. -
Row and Column transpose question
Dear Support ,
I would like to transpose one internal table , for example :
Column : MATERIAL , QTY , DATE
MA1 , 100 , 2009-01-01
MA2 , 200 , 2009-01-01
MA3 , 200 , 2009-03-02
After the convertion , it should be like that :
Column : MATERIAL , 2009-01-01 , 2009-03-02
MA1 100 0
MA2 200 0
MA3 0 200
As i know , in SQL it is very easy to do that , just like :
select sum(case ' xxx ' when ' xxx ' .... ) ....
But how to do that in ABAP ?
Thanks .

Rows to Columns conversion in an Internal Table
Hello All,
I have data like below:
Matnr1 ABC 100
Matnr1 ABC 200
Matnr1 ABC 500
Matnr2 XYZ 300
Matnr2 XYZ 600
I want data like this:

Is it possible? If yes, could anybody help achieving this?
Thanks a lot in advance.
AjayHi Ajay,
Try this.
( this is temp table for your formate)
data: begin of itab1 occurs 10,
line(150),
end of itab1.
Sort itab by col1 col2. ( Here itab is your table )
loop at itab.
at new col2.
write: / itab-col1,
itab-col2.
concatenate itab-col1
itab-col2
into itab1.
endat.
write itab-col3.
concatenate itab1
itab-col3
into itab1.
at end.
append itab1.
clear itab1.
endat.
endloop.

Hi,

=========================================
BULK INSERT Temp

FIELDTERMINATOR = ','
, KEEPNULLS
==========================================
Does anybody know what is happening and what needs to be done ?
PLEASE HELP
Thanks in advance
VikramTo load that file with BULK INSERT, use this format file:
9.0
4
1 SQLCHAR 0 0 "\"" 0 "" ""
2 SQLCHAR 0 0 "\",\"" 1 col1 Latin1_General_CI_AS
3 SQLCHAR 0 0 "\",\"" 2 col2 Latin1_General_CI_AS
4 SQLCHAR 0 0 "\"\r\n" 3 col3 Latin1_General_CI_AS
Note that the format file defines four fields while the fileonly seems to have three. The format file defines an empty field before the first quote.
Or, since you already have a .NET program, use a stored procedure with table-valued parameter instead. I have an example of how to do this here:

Can somebody help me here. thanks in advanceYou need pivot query like this, (I didn't list all the months)
select HOST, DB, TS,
max( decode( month, '2005-08', SIZE, null ) ) 2005_08,
max( decode( month, '2005-09', SIZE, null ) ) 2005_09,
max( decode( month, '2005-10', SIZE, null ) ) 2005_10,
max( decode( month, '2005-11', SIZE, null ) ) 2005_11
from ( select HOST, DB, TS, MONTH, sum(SIZE_MB) SIZE
from yourtable
group by HOST, DB, TS, MONTH)

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 thisHi,
Here's one way to do that:
WITH got_times AS
SELECT MAX ( CASE
WHEN msg_line = 'LONGITUDINAL REFRESH HAS BEGUN'
THEN msg_datetime
) AS start_time
, MAX ( CASE
WHEN msg_line = 'LONGITUDINAL REFRESH HAS COMPLETED'
THEN msg_datetime
) AS end_time
FROM xxwv.xxwv_hsum_info_reports
SELECT start_time
, end_time
, (end_time - start_time) * 24 * 60 AS duration_minutes
FROM got_times
;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. -
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!!!!

Hello All,
I have a requirement where I have to convert rows to columns and vice versa in 10g.
Pivot isn't supported in 10g.
Actual query looks like this
change_name primary_key_id
ASSET 1501
COLLATERAL 1501
ASSET 1502
COLLATERAL 1510
ASSET 1503
COLLATERAL 1515
Required Output:
change_table_name Asset Collateral
Primary_key_id 1501 1501
Primary_key_id2 1502
Primary_key_id3 1510
Primary_key_id4 1503
Primary_key_id5 1515Thx
Shank.

Pivot isn't supported in 10g.Pivot can be done in any version of Oracle.
The PIVOT keyword of the SELECT command isn't supported in Oracle 10. That's only one way of pivoting.
Actual query looks like this
change_name primary_key_id
ASSET 1501
COLLATERAL 1501
ASSET 1502
COLLATERAL 1510

Primary_key_id5 1515
I think you want something like this:
SELECT 'Primary_key_id
|| TO_CHAR ( NULLIF ( ROW_NUMBER () OVER (ORDER BY NVL ( a.primary_key_id
, c.primary_key_id
, 1
) AS change_table_name
, a.primary_key_id AS asset
, c.primary_key_id AS collateral
FROM table_x a
FULL OUTER JOIN table_x c ON a.primary_key_id = c.primary_key_id
-- Next 4 lines added after Ankit, below
AND a.change_name = 'ASSET'
AND c.change_name = 'COLLATERAL'
WHERE a.change_name = 'ASSET'
OR c.change_name = 'COLLATERAL'
;If you'd care to post CREATE TABLE and INSERT statements for your sample data, then I could test it.
This generates a unique change_table_name for each row. I don't see how you get the values you said you wanted associated with the other columns. That is, I have the same question as Justin:
Justin Cave wrote:
... How do you know that 1502 goes with primary_key_id2 and not primary_key_id3 or 4 or 1?Perhaps you don't really care which change_table_name is given to each row, just so long as they are unique, and numbered with consecutive integers (except for 1). If you really do need exactly what you posted, explain how you get it. You probably just need to change the analytic ORDER BY clause.
