Convert multiple rows into single rows for the respective index name

Dear Experts,
I want to convert multiple rows into single rows for the respective index name,
Here is my query.
SELECT user_tables.table_name, user_indexes.index_name, user_ind_columns.column_name
FROM user_tables
JOIN user_indexes on user_indexes.table_name = user_tables.table_name
join USER_IND_COLUMNS on USER_INDEXES.INDEX_NAME = USER_IND_COLUMNS.INDEX_NAME
where user_indexes.index_name not like '%PK%' AND user_ind_columns.column_name NOT LIKE '%SYS%'
ORDER BY user_tables.table_name,user_indexes.index_name;
Result of previous query
TABLE_NAME
INDEX_NAME
COLUMN_NAME
T1
IDX_ACCNTYPCFG1
ENABLE_SERVICE
T1
IDX_ACCTTYPCFG1
ACC_CODE
T1
IDX_ACCTTYPCFG1
ACCTYPE
T2
IDX_ACCTTYPCFGAPP1
ACCTYPE
T3
IDX_ACTLG1
MOBILE_NO
T3
IDX_ACTLG1
ID
Desired output required is
TABLE_NAME
INDEX_NAME
COLUMN_NAME
T1
IDX_ACCNTYPCFG1
ENABLE_SERVICE,ACC_CODE,ACCTYPE
T2
IDX_ACCTTYPCFGAPP1
ACCTYPE
T3
IDX_ACTLG1
ACCTYPE,MOBILE_NO
please help.

Maybe
with
user_tables as
(select 'T1' table_name,'IDX_ACCNTYPCFG1' index_name,'ENABLE_SERVICE' column_name from dual union all
select 'T1','IDX_ACCTTYPCFG1','ACC_CODE' from dual union all

select 'T3','IDX_ACTLG1','MOBILE_NO' from dual union all
select 'T3','IDX_ACTLG1','ID' from dual
select table_name,
case index_name when 'IDX_ACCNTYPCFG1' then 'IDX_ACCTTYPCFG1' else index_name end index_name,
listagg(case column_name when 'ID' then 'ACCTYPE' else column_name end,',') within group (order by null) column_name
from user_tables
group by table_name,case index_name when 'IDX_ACCNTYPCFG1' then 'IDX_ACCTTYPCFG1' else index_name end

Merge multiple rows into single row (but multiple columns)

How to merge multiple rows into single row (but multiple columns) efficiently.
For example
IDVal IDDesc IdNum Id_Information_Type Attribute_1 Attribute_2 Attribute_3 Attribute_4 Attribute_5
23 asdc 1 Location USA NM ABQ Four Seasons 87106
23 asdc 1 Stats 2300 91.7 8.2 85432

65 affc 2 Stats 5510 42.7 46 9999
65 affc 2 Audit 1996 July 172 1100
where different attributes mean different thing for each Information_type.
For example for Information_Type=Location
Attribute_1 means Country
Attribute_2 means State and so on.
For example for Information_Type=Stats
Attribute_1 means Population
Attribute_2 means American Ethnicity percentage and so on.
I want to create a view that shows like below:
IDVal IDDesc IDNum Country State City Hotel ZipCode Population American% Other% Area Audit Year AuditMonth Audit Type AuditTime

Hi,
That's called Pivoting . The forum FAQ has a section on this subject: {message:id=9360005}
I hope this answers your question.
If not, post your best attempt, along with a little sample data (CREATE TABLE and INSERT statements, relevant columns only), and also post the results you want from that data. (You did post the results you wanted, but they're very hard to read because they're not formatted. Use \ tags, as described in the forum FAQ, below.)
Explain, using specific examples, how you get the results you want from the data given.
Always say which version of Oracle you're using (e.g., 11.2.0.2.0). This is always important, but especially so with pivots.
See the forum FAQ {message:id=9360002}

If you understand how SQL statements are executed it's along these lines...
1. Open Cursor
2. Parse SQL statement and determine columns
3. Bind in any input values
4. Fetch data
5. Bind out values to columns
6. Repeat step 3 until no more data
7. Close cursor
Now, you're expecting that you can determine the columns (step 2) from the fetched data (step 4 onwards). You can't. The SQL engine needs to know the expected columns before any data is fetched so, it can't base the number of columns on the data itself.
If you need that requirement, you would need to query the data first and build up a dynamic query based on the data and then execute that dynamically built query to fetch the data and pivot it into those columns, which means that you have queried the data twice. Not good practice and not good (or simple) coding.
What you're talking of doing is something that should be handled at the presentation/interface layer, not as part of the data fetch.
Typically these sorts of things are handled most easily in report generation/writer tools such as Oracle Reports, Business Objects etc. where they fetch the data from the database and then process it to format it on the display, pivoting the results as required.
It's not something that lends itself to be easily achieved in SQL. Yes, SQL can do pivoting of data quite easily, but NOT with a dynamic number of columns.
If you were to specify that there is a maximum number of columns that you could get (rather than wanting it dynamic), then you can do it simply in SQL with the max-decode method...

ALV - Multiple Rows into Single Row

I have a requirement to display the ALV output from CDHDR&CDPOS tables here in the output i have 15 columns( Fields ) any changes im displaying in report output ,but if there is same time multiple columns will change im displaying as individual record instead of that i need to show as single row.
in this output last three records have same time change but i have populated into three different columns i want to make it as SINGLE Row Record.
Thanks!!

We don't need script task for this. Use TSQL in the datasource. Refer below example
DECLARE @TEMP TABLE(ID INT, [VALUE] NVARCHAR(30))
INSERT INTO @TEMP VALUES(1 , 'MAZ')
INSERT INTO @TEMP VALUES(1 , 'HON')
INSERT INTO @TEMP VALUES(1 , 'FOR')
INSERT INTO @TEMP VALUES(2 , 'JEEP')
INSERT INTO @TEMP VALUES(2 , 'CHE')
INSERT INTO @TEMP VALUES(3 , 'NIS')
INSERT INTO @TEMP VALUES(4 , 'GMC')
INSERT INTO @TEMP VALUES(4 , 'ACC')
INSERT INTO @TEMP VALUES(4 , 'LEX')
SELECT [id],
Stuff((SELECT ',' + [VALUE]
FROM @TEMP
WHERE [id] = a.[id]
FOR xml path('')), 1, 1, '') [VALUE]
FROM @TEMP a
GROUP BY [id]

The group will be either X or Y only.
Can anyone help me out pls

Combine 2 rows into single row?

I have a table A which has information related to a process. For process completion there exist 2 rows. One has in it the total elapsed time, the time the entire process (which is multipart) begin and end time, but the columns related to rows processed are blank. Another related row has a start, end and elapsed time in it -- which I don't want -- but it has the row counts that I do want.
I want to take these 2 rows, combine the relevant information into 1 row and insert that row into table B.
I know I could insert from the first row and then come back and update it from the second row, but I hate having to read Table A twice. Any suggestions?

Function Module to convert multiple records into single record and vice-ver

hi,
i have a requirement to convert 10 records in an internal table to single record which should be passed
to a single variable and store in the database.Kindly let me know is there any function module
which meets my requirement. Also i need to do split one single record to 10 records each of
say 65 length interval.
kindly provide me if there is nay functinon module as such.
I can do with ABAP-OOPS.Please suggest function module.

I dont think such FM exists, but if you wanna code one it would be simple. Just loop through the internal table, keep concatenating the currently processing record into a long character variable to convert 10 records into one record.

Convert multiple delivery into single invoice

Hi all,
Kindly give solution to the below scenerio:
The delivery is created each time the material is being send to the customer, But the customer requires a single invoice for all the delivery at the end of each month. How to address the scenerio.
With regards,
Afzal

Hi ! Afzal,
In the customer master record on the Sales Area Data, in the billing tab page, we have a field called Invoice dates.
In that field, if you maintain a Factory Calender which has a set up of the dates, monthly one of the days, you can achieve your requirement.
In the standard system for such a requirement Factory calender 'AM' is available. So fill in the field mentioned with Factory Calender 'AM - Agreement Monthly'.
Now when you run Billing due list, all the deliveries that have been executed during the month will be available in billing due list only at the end of the month for this customer. Billing due list will be as regular for other customers. In this way, deliveries can be combined.
Regards,
PATHIK

I meant is there a way to do it without using a table?
LISA86
We have not used any extra table. Ok, Try the below:
Select distinct
names= REPLACE(
Select a.Name as [data()]
From YOURTABLENAME A
Where A.Rnk = b.Rnk
Order by a.Name
FOR XML PATH ('') ), ' ', ',') ,Rnk
From YOURTABLENAME B Order by Rnk

Concatenating multiple rows into Single Row

Hi Experts,
I have got a new challenge in my project, but i am not aware of that one, please help me...
i have a source like this
col1    col2
1         a
1         b
1         c
my target would be like this
col1     col2
1          a,b,c
i know how to achieve this in SQL( using LISTAGG( ) or wmconcat( ) ), BUT........
how i can load this into ODI Target table, pleae explain in detail ..
Cheers
Venkat

Hi,
You should be able to map your LISTAGG function on the target datastore as Col2, if you get in problems with group by , try this trick to supress the group by from ODI :

To achieve this i have tried with multiple Field routines , but data is not populating for all partner fields .
Out put in DSO

Hi Raf /Rajesh ,
Thank you so much for your replies
@ Raf Rule group will update data into multiple rows ..
@ Rajesh
1.In my data only Falg is differentiator .
2.You need to create multiple Infoobjects to meet your requirement. --May i know what do you mean ??, already i have created multiple infoobjects for every partner w.r.t falg .
Shown in above data
3.Also you are not sure whether the data from source is always consistent like    5 distribution channels, 5 flags etc. - in data i will have only 5 different flag value -F1,F2,F3,F4,F5
I am wondered to know why multiple field routines are not working ....
Regards ,
Hari

Convert multiple rows into single rows for the respective index name
