  • How can'i use wm_concat in ODI 10

    Hello

    I would like to know how to use the wm_concat function in an ODI interface (I use 10 ODI)

    For example, I have the following source data

    A    B     C
    

    ---       --- -------
    

    20     5     SMITH
    

    30     3     ALLEN

    20     2     ADAMS
    

    30     5     JAMES
    

    20     1     FORD
    

    10     5     MILLER

    and I want to insert the next data kes

    A     sum(B)     wm_concat(c)

    20     15      SMITH,FORD,ADAMS,SCOTT,JONES
    

    30     20      ALLEN,BLAKE,MARTIN,TURNER,JAMES,WARD

    by adding a function of sum () in the column mapping B.

    The following query generates the ODI

    SELECT A, SUM (B), WM_CONCAT (C)
FROM <table>
GROUP BY A, WM_CONCAT (C);

    This means that the ODI does not recognize WM_CONCAT as aggregate function.

    don't you think that it is possible to say ODI to do not function in the group by

    PS: I use an Oracle 11 g database 2 which recognizes the WM_CONCAT function.

    Thank you very much

    Hello

    WM_Concat is no longer valid, that it has been deprecated by oracle, a long time ago.

    Using the LISTAGG function instead... It should work in ODI...

    SELECT deptno, LISTAGG (ename, ',') INTRA GROUP (ORDER BY ename) as employees

    WCP

    GROUP BY deptno;

    DEPTNO EMPLOYEES

  • lines due to the wm_concat() in double request gorge yourself

    Here's the query I need to run

    SELECT the separate user interface. Index_name, UI. Owner, UI. Table_name, wm_concat (uic.column_name) on column_name (partition by order of position_colonne uic.index_name), the ui.index_type, the parameters
    Of

    and ui.index_name not like 'SYS_C00% '.
    and ui.index_name not like 'SYS_IOT_TOP_ %' and owner = 'USER1 '.
    control of the user interface. INDEX_NAME



    The problem is wm_concat() because the all_IND_COLUMNS table contains the entry duplicated for index (index1 of the table(column1,column2,column3) type)

    for this wm_concat returns the result as below:
    --------------------
    Column1
    Column1, Column2
    Column1, Column2, Column3

    But in * result I don't need it for a particular name of index (separate index)

    as an example, I have two indexes in schema:
    index1 on table1 (column1, column2, column3) and
    Index2 on table2 (column5)

    This result need
    Row1 - index1 Column1, Column2, Column3
    Index2 column 5 row2-


    my query returns
    index1 Column1 row1-
    row2 - index1 Column1, Column2
    row3 - index1 Column1, Column2, Column3
    row4 - column 5 index2

    Are you trying this?

    SELECT UI.INDEX_NAME,
  ui.owner ,
  UI.TABLE_NAME ,
  ui.index_type,

  listagg(column_name,',') within GROUP (

  • How to get distinct records by using the ListAgg OBIEE report function?

    Hi all

    I get a correct result as mentioned below. But I don't see duplicates in my result here, in my example, I get duplicate for the name of the employee 'Pat '. So how to get Distinct values by using the LISTAGG function?

    Data set of sample with the Department and its employees

    Service employee

    ----------      ----------

    Marketing Michael

    Pat of marketing

    Pat of marketing

    Pat of marketing

    Purchase of Den

    Purchase of Alexander

    Purchase of Shelli

    Purchase of Sigal

    Guy of purchase

    Purchase of Karen

    Using the ListAgg function, we can convert it to:

    Employees of the Department

    -----------     -------------------------------------

    Marketing of Pat, Pat, Pat, Michael

    Purchase of Sigal, Shelli, Karen, Guy, Den, Alexander

    I tried a lot of things, but I'm not able to understand how exactly this can be achieved, if anyone has any idea or suggestions please do share, thanks in advance.

    After much research, I found the solution & I want to share what he finds very useful, we can create SQL logic in the Advanced tab, as below and after you click Rescan, and then you will get your desired results.

    SELECT saw_0, Evaluate_Aggr T1.dept ("ListAgg(%1,'' & '') intra group (about 1%)") ("as long as VarChar (1000), T1.emp) saw_1 FROM)

    SELECT 'emp_dept '. "the Department dept,

    'emp_dept '. "' employee ' emp

    IN THE "DOMAIN".

    GROUP BY dept, emp

    ) T1 GROUP FROM T1.dept ORDER BY saw_0

    Also note here that we have good anti-aliasing for columns parent (ex: saw_0, saw_1), another by mistake oracle bi server.

    EDIT: There are "n" lines for ptpos_list. So, we need to manage the many values of ptpos_list.

    Hello

    This is a feature annoying LISTAGG - you cannot use DIFFERENT with her.

    A workaround is to to a separate GROUP BY, or SELECT DISTINCT simply get the unique values, then call LISTAGG on these unique results, like this:

    WITH got_distinct_ptpos_list AS

    (

    SELECT id, part_type_id, ptpos_list

    OF ptpos_explanations

    GROUP BY id, part_type_id, ptpos_list

    )

    SELECT id, part_type_id

    LISTAGG (ptpos_list, ',')

    THE Group (ORDER BY ptpos_list) in the form of recommendations

    OF got_distinct_ptpos_list

    GROUP BY id, part_type_id

    ;

    LISTAGG isn't the only way to get the desired results.  See https://oracle-base.com/articles/misc/string-aggregation-techniques for other ways to string aggregation, including a user-defined aggregate function and SYS_CONNECT_BY_PATH.

    REGEXP_REPLACE should work, too.  What exactly have you tried?  (However, it is probably more effective to get the unique results immediately the bat, rather than producing more than you want and then by doing something more to get rid of the duplicates).

    Hello Tom,

    listagg() is not supported for fast refresh.

    http://docs.Oracle.com/CD/E11882_01/server.112/e25554/basicmv.htm#i1007028

    Only SUM, COUNT, AVG, STDDEV, VARIANCE, MIN and MAX are supported to fast refresh.

    Kind regards

  • LISTAGG and DBMS_SQL

    Oracle 11 g 2

    It is a check-in process. MY_TAB is the source table and MY_TAB_ARC is the check-in table. MY_TAB_ARC has two additional columns - dt_archived and remarks.

    Currently, these columns are the last columns of the table of check-in, but there is no guarantee of this. Because you can add new columns in the source table in the future.

    create table my_tab
( id    number ,

create table my_tab_arc
( id    number ,
  list  varchar2(50) ,

    Am I missing something here? Or you cannot use LISTAGG in DBMS_SQL?

    I say knock yourself out.

    Dynamic SQL has its place.

    I have it would probably become a procedure you want to call it.

    Things that you can examine and possibly already have:

    This does not cover a deletion, nor is there follow-up to what has or has not been archived.

    Depending on the size, link in bulk and batch inserts may need to be worked in code similar to this one. (Yes, she gets more complicated)

    Make sure you have no constraints on your table to archive. (unless you want to build in the error handling)

    I have built in error management then it throws an exception when a column has not yet been added to the table to archive.

    You can write code to add columns to your table to automatically archive, but I just wanted to show that what you want is possible.

    You a little too much code, but you were close.

    declare
v_source_table varchar2(30) := 'MY_TAB';
v_id_to_archive number := 1;
v_destination_table varchar2(30);
v_verify_cols varchar2(4000);
tab_columns varchar2(4000);
v_sql clob;
begin

v_destination_table := v_source_table||'_ARC';

select listagg(src.column_name,',') within group (order by src.column_id) tab_columns into v_verify_cols
  from user_tab_cols src
where not exists (select 1 from user_tab_cols trgt
where trgt.table_name = src.table_name||'_ARC'
   and src.column_name = trgt.column_name)
   and table_name = v_source_table;

if v_verify_cols is not null
  then raise_application_error(-20001,'Columns Missing In Archive Table: '||v_verify_cols);
end if;

    and src.column_name = trgt.column_name

    and trgt.table_name = v_destination_table
    and trgt.virtual_column = 'NO';

v_sql := 'insert into '||v_destination_table||' ('||tab_columns||',dt_archived,remarks)
select '||tab_columns||',sysdate,''ARCHIVED'' from '||v_source_table||' where id = :id';

  • Query complex REGEXP LISTAGG

    Hello world

    I have a problem with a complex regular expression, maybe I'm over complicating it.

    Essentially, what I have is some interactions, interaction can go to several queues over time, what I need to achieve is when the queue of the item is listed as WORKBIN or OFFICE I want to find the queue that was before that. Things get complicated, because sometimes I have an example where he goes queue > QUEUE > WORKBIN > TAIL > DESKTOP >TAIL> WORKBIN I need to find the line in "BOLD".

    What I tried was the LISTAGG a partition of interactions for a list as a QUEUE. QUEUE | WORKBIN | QUEUE | DESKTOP COMPUTER | QUEUE: WORKBIN can use REGEXP_INSTR to cut the chain out, but I can't seem to find the latest iteration of the expression.

    Here is an example of the data:

    queue of the date interaction_id

    1037150 2015-01-21 07:56:40 desktop_in_progress

    And the statement that I have tried:

    UBSTR (SUBSTR ('|)) ' || LISTAGG (LAST_QUEUE_NAME, ' |') Group (order of AGENT_END_TS) on (INTERACTION_ID score) |' | ', 1, REGEXP_INSTR ('|) ' || LISTAGG(LAST_QUEUE_NAME, '|') Group (order of AGENT_END_TS) on (INTERACTION_ID score) |' | ((',' desktop_in_progress', 1-2), INSTR (SUBSTR ('|)) ' || LISTAGG (QUEUE_NAME, ' |') Group (order of AGENT_END_TS) on (INTERACTION_ID score) |' | ', 1, REGEXP_INSTR ('|) ' || LISTAGG(QUEUE_NAME, '|') Group (order of AGENT_END_TS) on (INTERACTION_ID score) |' | ((',' desktop_in_progress ', 1-2),' | (',-1) + 1, REGEXP_INSTR ('|) ' || LISTAGG(QUEUE_NAME, '|') Group (order of AGENT_END_TS) on (INTERACTION_ID score) |' | ((',' desktop_in_progress', 1-2)

    Any help or suggestions appreciated
