How to use the Group condition in the ODI mappings

Hi Experts,

I have a requirement in the customization of BI applications. Can you please someone explain how to use the LISTAGG function in odi mapping.

I applied the LISTAGGR function at the level of mapping odi, but I get error below.

Mapping of ODI: ColumnName: ENAME Expression: LISTAGG (EMP. ENAME, ",") THE GROUP (RANKING BY EMP. ENAME)

Error:

ODI-1240: Flow LIST_AGG_FUN_USAGE fails during an operation of integration. This flow of charge table target EMP_BI.

ODI-1228: task failed LIST_AGG_FUN_USAGE (integration) on the scott_db of ORACLE target connection.

Caused by: java.sql.SQLSyntaxErrorException: ORA-00937: not a function of simple-group


Oracle query:

If I used this sql query in the database the correct result is.

SELECT DEPTNO, LISTAGG (ENAME, ',') WITHIN THE EMP EMP (ENAME CONTROL) GROUP. DEPTNO;

Output:

10CLARK, KING, MILLER
20ADAMS, FORD, JONES, SCOTT, SMITH
30ALLEN, JAMES, MARTIN, BLAKE, TURNER, WARD


Please give your valid solutions, thanks in advance.

Kind regards

If you try in #ODI12C then in the set of properties, you can select the column which should be used to group by.

If it's 11g so its bit complicated. Simply replace the mapping with below codes.

LISTAGG (EMP. ENAME, ",") WITHIN GROUP (ORDER BY ENAME) / * sum() * /.

Magic!

Thank you

Chantal

  • How to use the search otherwise condition as

    Oracle 9i

    Hi all

    I work in the management of control here, we have a table named as OE_ORDER_LINES_ALL and the name of the column called UPI, and its length is 16 tank.

    Now the customer has the UPI with 13 tank and now, I need to check if all the IPUS are in the table.
    I have almost 600 of the UPI and I can't able to use as an operator. Y at - it one option other than as an operator.

    For example

    Resemble UPI this 050 009714373007G, but the customer gave this G 009714373007.

    Is there a UPI then I would use like this

    "Select upi in oe_order_lines_all where the upi as ' 009714373007 G %.

    If there is more than 2 UPIs how to use the search condition

    Any help is highly appricatable

    Thanks and greetings
    Srikkanth.M

    If you know that you will benefit from a number of values of UPI 13 characters and you should look for if there are rows in the table that match the 13 first characters

    select upi
      from oe_order_lines_all
     where substr(upi,1,13) IN( '009714373007G', <> )

  • How to use the global variable in the table target?

    Hello

    I am trying to load several files into a single interface. the data is loaded successfully. 92. the files are there. for this I used variables and package.

    My requrement is 92 files of data loaded into the target table. I want to know what data from file.

    to this I added a column (filename) to the existing target table.

    If I used joints (not same condition), its totally wrong. all file names are coming.

    Please see the following screenshots.

    err27.jpg

    exit; target table.

    err26.jpg

    in fact in the target table. first 10 lines are coming from file.i.e first _ACCOUNT_LIMIT_511.TXT. but all the files names are coming.

    I'm confuse. After the first data file inserted then insert second data file. in that all file names are coming. Please help me.

    I thought that the global variable is preferable to identify the data came from which file.

    to do this, the global variable is used in the target table. I don't always have my exit.

    Please help me.

    Thanks in advance.

    err25.jpg

    Hello

    You can use the same way, how you use the project variable, just you have to do a thin is #GLOBAL.variable_name for example: #GLOBAL. SMART_AL_FILE_NAME_S

    Note: Make sure you that while you use one variable overall in interface, indicator should be staged as you chose above the screen

    hope this helps you

  • With no headphone jack, how to use the iPhone in my car 7

    Okay, so here's the challenge.  I have a power source and a headphone and not Bluetooth.  It works perfectly with iPhones before 7.  But with 7, it isn't possible to use the same configuration I had for years.  I own my car, and I have no interest in buying a new car just to support a new phone.  And since this will be a problem for the years to come if I stay with Apple, I would like to know what are the solutions are available.

    So, how to use the new iPhone 7 while remaining responsible and using my car speakers?  Dongles Bluetooth that I need to reload, it's probably not.

    Thus, looking for ideas that might have people.  I can't be the only one with this concern.

    It's almost a certainty that a third party adapter will appear quickly. The new Macbook has a single port usb - c and people asked the same question, 'how to load and use USB at the same time." There are today dozens of solutions for the Macbook, and then it will be with the iPhone 7. An adapter with a 3.5 mm jack and a port of loading Lightening would be my guess. Kickstarter entrepreneurs are probably already working on it.

  • How to use the capture and the print button

    I tried to figure out how to use the capture and the "print" button, or add or what you call. I press it and the whole page of a different color changes, so I try to cut the section I want but I don't know how to send it to the printer. Can someone help me with this. I'm not at savvy with tech stuff, but when I find a recipe or something and it doesn't have an option to print a certain area, I can't understand how to use it?

    Thank you

    Andi Starbuck

    That happens to me is, I click and drag to make a rectangle of yellow selection, and as soon as I raise my finger on the mouse button, the part I've selected is captured as an image, a new tab opens and preview before printing, the image display. I can use the installation of the Page or simply print. But if I close the preview, this temporary image vanishes and I'm back on the page where I started. You see something different?
