Merging Mulitiple Rows into single row

Hi All ,
I am loading master data to DSO from PSA .
In my source i have got 5 records for specific keys
Ex : Customer Divis  DistChan   Flag   Partner1    Partner Name
           1            PC     11          F1     11                    Jhon
           1            PC     11          F2     12                    Jone
           1            PC     11          F3     13                    Jack
           1            PC     11          F4     14                    Jame
In Target i need to have data in single records
Ex :
: Customer Divis  DistChan   Flag   Partner1    Partner1 Name  Partner2     Partner2 Name  Partner3     Partner3 Name Partner4     Partner4 Name
      1            PC     11       F1             11                 Jhon              12                    Jone         13            jack                 14              Jame
To achieve this i have tried with multiple Field routines , but data is not populating for all partner fields .
Out put in DSO
Customer Divis  DistChan   Flag   Partner1    Partner1 Name  Partner2     Partner2 Name  Partner3     Partner3 Name Partner4     Partner4 Name
      1            PC     11       F1             11                 Jhon       
Any inputs why its not populating data for other fields ...is there other method to make this ??
All your valuable inputs are appropriated
Thanks in advance
Regards ,
Hari    

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

  • 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...

  • 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?

  • Merge 2 rows into single row with data update?

    hello all,
    i have a table with below data,

    insert into @tbl values (2, 'env2', '5/4/2010', '6/6/2012')
    --earlier start data is '4/4/2010' from 'env1'
    --latest end data is '6/6/2012' from 'env2'
    insert into @tbl values (3, 'env1', '3/3/2010', '4/4/2012')
    insert into @tbl values (4, 'env2', '2/2/2010', '5/5/2012')
    --earlier start data is '2/2/2010' from 'env2'

    i need to merge 2 rows for column  "uname" having value "env1" & "env2" to "envZ" and need to capture earlier start date and latest end date from both and update with new.
    the desire output should be,
    declare @tbl table (uid int, uname varchar(10), start_dt date, end_dt date)
    insert into @tbl values (1, 'envZ', '4/4/2010', '6/6/2012')
    insert into @tbl values (4, 'envZ', '2/2/2010', '5/5/2012')

    insert into @tbl values (6, 'envX', '9/9/2010', '10/10/2012')
    insert into @tbl values (6, 'envY', '9/9/2010', '10/10/2012')
    note - i must need to update one row and delete other row as i can't insert new rows (having huge data with other columns also).
    please suggest optimize query. thanks!

    Which version and edition of SQL Server are you using?
    Whenever there is a row with 'env1', there is a corresponding 'env2' and vice versa? 
    The row with 'env2' is always after the row with 'env1'?   (uid+1)
    If the answers are yes to both questions above, here's a possibility:
    -- code #1 v3
    ;with
    ENVZ as (
    SELECT uid= case when T1.start_dt <= T2.start_dt then T1.uid else T2.uid end,
    start_dt= case when T1.start_dt <= T2.start_dt then T1.start_dt else T2.start_dt end,
    end_dt= case when T1.end_dt > T2.end_dt then T1.end_dt else T2.end_dt end
    from @tbl as T1
    inner join @tbl as T2 on T2.uid=T1.uid+1 and T2.uname='env2'
    where T1.uname = 'env1'
    MERGE
    into @tbl as T3
    using ENVZ as T4
    on T3.uid = T4.uid
    when matched and (T3.uname in ('env1','env2')) then
    UPDATE set T3.uname= 'envZ',
    T3.start_dt= T4.start_dt,
    T3.end_dt= T4.end_dt
    when not matched by source and (T3.uname in ('env1','env2')) then
    DELETE;
    The table @tbl is read three times in the above code. There are probably ways to optimize the above code. Or even other more efficient approach.

    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 :

  • Multiple rows into single row

    i have a table
    EID Code
    1 100
    1 101

    i want to get the output as Eid code code1 code2
    1 100 101 104
    2 102
    can anyone suggest on this?

    Not sure why so many are suggesting string aggregation techniques when the OP said...

    1    100   101  104
    2    102 Clearly the output is required in seperate columns, not as one aggregated string.
    The solutions should relate to pivoting, not string aggregation.

    Assumed the date values are actually DATE types.
    Partition on DT and RNO can be amended as per your requirement..
    And assumed your sample data has a typo..
    If your data is correct..
    with x as
    select 991 rno, 9 from_sqn ,11 to_sqn ,to_date('2010-01-01','yyyy-mm-dd') dt
    from dual union all
    select 991, 15 ,22 ,to_date('2010-01-01','yyyy-mm-dd') from dual union all
    select 991, 22 ,33 ,to_date('2010-01-01','yyyy-mm-dd') from dual union all
    select 992, 33 ,44 ,to_date('2010-01-01','yyyy-mm-dd') from dual

  • Merging rows into one row but into SEPARATE Columns

    Hello Gurus,
    I have searched alot on OTN and many other places, but no where I could get the solution of how can we merge rows into one row but separate column. For example
    Consider the below scenario
    "DEPARTMENT", "EMP","NAME","SUBJECT"
    "Electronics","1","Sam","LIC"
    "Electronics","2","Pam","VLSI"
    "Electronics","3","Tom","C"
    "Mech","1","Abu","Thermo"
    "Mech","4","Lina","Machines"Now, I need the output like
    Based on Department as Group By Clause
    "DEPARTMENT", "EMP1","NAME1","SUBJECT1","EMP2","NAME2","SUBJECT2","EMP3","NAME3","SUBJECT3"
    "Electronics","1","Sam","LIC","2","Pam","VLSI","3","Tom","C"
    "Mech","1","Abu","Thermo","4","Lina","Machines"
    The row data to be loaded into separate columns. Name of the column is not an issue... can be anythingIn all the forums which I went through I could find them loading into a single column, but not into respective separate columns.
    Any help would be much appreciated.
    Thanks

    Frank,
    I saw your name nearly n number of times, as I went through many forums today... And the link which you have just posted, I went through it today afternoon.
    Could you please explain this bit taken from your dynamic pivot post.
    SELECT     DISTINCT
         ',     COUNT (CASE WHEN job = '''
    ||     job
    ||     ''' '     AS txt1
    ,     'THEN 1 END)     AS '
    ||     job
    ||     '_CNT'     AS txt2
    FROM     scott.emp
    ORDER BY     txt1;Many Thanks.You only need that when you need column aliases based on the actual data (and you explicitly said you don't need that) or when can't put an upper bound on the number of columns to be displayed. If that doesn't apply to this problem, then don't use any kind of dynamic SQL (like the code above); it makes the job much more difficult, less efficient and less robust.
    Here's what the code above is doing.
    If you were hard-coding a query that showed the number of people in each job, and you knew that the possible jobs were 'ANALYST', 'CLERK' and 'MANAGER', then you might hard-code a query like this:
    SELECT    deptno
    ,       COUNT (CASE WHEN job = 'ANALYST'  THEN 1 END)     AS analyst
    ,       COUNT (CASE WHEN job = 'CLERK'    THEN 1 END)     AS clerk
    ,       COUNT (CASE WHEN job = 'MANAGER'  THEN 1 END)     AS manager
    FROM       scott.emp
    GROUP BY  deptno
    ;If the jobs had different names, or if there were not 3 different jobs, then you would have to change the lines in the SELECT clause that start with ", COUNT ( CASE ...".
    The code you posted is from an example of dynamic SQL, where you first run a Preliminary Query . (What you posted above is, in fact, the complete preliminary query.) The output of that preliminary query is exactly the variable part of the real query, such as:
    ,       COUNT (CASE WHEN job = 'ANALYST'  THEN 1 END)     AS analyst
    ,       COUNT (CASE WHEN job = 'CLERK'    THEN 1 END)     AS clerk
    ,       COUNT (CASE WHEN job = 'MANAGER'  THEN 1 END)     AS managerYou then use this output as part of your main query. In other words, you can write something today that will generate exacrly as many columns as you need next year, with names from the data as it is next year. How? because you're not writing the full query today. The variable part will be written by the preliminary query when it runs next year.
