How to break the if condition

Hi guy,
I wrote a "pr_suppalloc_rules" procedure, this procedure I called sub procedure 'pr_suppalloc '.
In the procedure '(pv_mro_no, pv_status) pr_suppalloc' I pass the two parameter. pv_mro_no is in parameter.
pv_status output parameter and it is illustrated the procedure success or failure. If this is faliure, I get code sqlerror.

create or replace procedure (pv_mro_no in varchar2, pv_type in varchar2, pv_status out varchar2)
is
Start
pr_suppalloc (pv_mro_no, pv_status);

If pv_status is not null then
Rollback;
Dbms_output.put_line (pv_status);
*--> How come out of this if condition.
end if;

pr_suppalloc_rule1 (pv_mro_no, pv_status);

end;
*-> From this moment, I get out of this proceudre.
I used OUT there but can't access the PL/SQL.
Could you help me.

Thanks in advance.

If you really want to stop the execution of this procedure within the FI... END IF; block, you can use the RETURN; statement...

create or replace procedure ( pv_mro_no in varchar2,pv_type in varchar2,pv_status out varchar2) is
begin
  pr_suppalloc (pv_mro_no,pv_status);

  if pv_status is not null then
    rollback;
    DBMS_OUTPUT.put_line (pv_status);
    --> How to exit this if condition.
    RETURN;
  end if;

  pr_suppalloc_rule1 (pv_mro_no,pv_status);
end;

Although you can find better coding practice to implement exceptions defined by the user and use a STIMULUS; instead...

create or replace procedure ( pv_mro_no in varchar2,pv_type in varchar2,pv_status out varchar2) is
  ex_null_status exception;
begin
  pr_suppalloc (pv_mro_no,pv_status);

  if pv_status is not null then
    RAISE ex_null_status;
  end if;

  pr_suppalloc_rule1 (pv_mro_no,pv_status);
exception
  when ex_null_status then
    rollback;
    DBMS_OUTPUT.put_line (pv_status);
end;

  • Re: Satellite A300 - how to restore the original condition?

    Hello

    My computer freezes for a second or 2 from time to time and Toshiba support told me it might be a software problem. I don't think, because he began the day I bought the laptop and the display driver keeps on the work stoppage, but because I said that if it's a software problem.
    I would have to pay for it, I want to try everything before sending it for repair. This is why I would like to restore my Satellite in its original state as he was just at the moment where I bought it.

    So basically I have 2 questions:

    1 - does anyone have any idea why it keeps freezing on me? And what I should try to do to fix it?
    2. can someone tell me how to restore the laptop to its original state?

    Thank you very much Dina

    Hello

    To determine if it of a software problem or not, you need to restore the factory setting and if it doesn't work you can go to an authorized service provider. They can repair the laptop for you.

    The factory settings can be restored with the Toshiba recovery disc. I guess that your laptop has been delivered with Windows Vista, if you have options to restore factory settings: the Toshiba disk recovery or HARD drive recovery service.

    HARD drive recovery function formats the first partition of your laptop and install Vista again with all the drivers and tools of Toshiba. It is an image that is stored on the second partition of HARD drive in the folder HDDRecovery.
    If you go into the advanced with F8 boot menu after you start the computer, you can start this feature of Toshiba. And then select Repair my computer and some Windows files will be loaded. Then, you can choose the function to drive HARD Toshiba Recovery and follow the instructions on the screen.

    The Toshiba Recovery disk, you must create first, or have you done this yet? Normally, you get a reminder of recovery message after the first start of the laptop that you must burn this disc. Therefore, you must the preinstalled Toshiba recovery disc creator and the image in the folder in HARD drive recovery will be burned on the disc. Then you have a startup disk that can restore the factory settings and HARD whole disc formats then back up your data first!
    The recovery disk is necessary if you have a new HDD or Windows start doesn t. Otherwise, you can use HARD drive recovery.

    I hope I could help a bit and now you understand how to restore the factory settings.
    If you have any other questions, please let us know! :)

    I tried to move the directory in E:\ back to C:\, but received a parsing error.

    The directory c: is not really a directory; It is a library which is
    just a pointer to the real directory on E:, a bit like a shortcut.

    So if you get there via the library or the directory, you are in
    in the same place - E:\My Documents and any changes there are also
    See in the library.

  • 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:

    Please give your valid solutions, thanks in advance.

    REDA

    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

    And that you pass as the input... I'm guessing that you spend the entire load as input...
    If Yes, then you will always get the first element...
    you have two options here...

    (1) your you change the entry of transformation so that it accepts that the entrance is the only unit of

    8786
    Sandrine

    and the GET the desired output
    .. u must send the entry under tns:getReportMetadataResponse/back/ns0:ReportMetadataCollection / ns0:ReportMetadata / ns0:ABCData [$CounterVariable]

    (2) change the transformation to accept a number as an input parameter and then your transformation should look like:-pass the $Counter also as input variable...

  • How to put the OR condition in IdXML

    I wanted to find all the users who meet the search criteria th "FirstName = John OR FirstName is Sally." How can I do it in IdXML OAM?

    By default, IdXML put 'AND' condition if more than one search parameter is provided. Is it possible to put an OR condition between IdXML search setting?

    Thank you!
    Kabi

    Hi k,

    In the oblixappparams.xml of the server identity file, there is a searchSameAttrAsOr parameter which can be set to true. Does research using the same attribute (as in your example with name) OR rather research AND research, but the research on different attributes remain ANDS. This works for the UI, and I guess that's the same thing for IDXML, although I have not tried it myself.

    Kind regards

    Could someone help me with this issue?

    Farid Ali

    Ridwan,

    Since you have a SISO system, you can try using the screw "Design Control" to convert the transfer function after normalization of State-Space model, you can use a function 'hidden' in the design of control that are used to calculate the original terms of your system. This function will calculate the necessary value to States in order to obtain the desired result, based on the model. If your initial release is zero, the Conversion.vi cd_IC will give you an empty model and to avoid an error, then change its value to zero.

    As an attachment, you have an example and a screw that you allow to use it in 2009 LV.

  • How to avoid the race condition critical in the event loop?

    I'm having a problem of race in the structures of the event.  I looked through various discussions of the forum and have not been able to track down a solution.

    In the attached vi (labView2015), if you type a new number for 'X', are not press entry, and hit then the "Go" button, then the old value of 'X' is used in the case of structure.  I deduce that it is a problem of race where after clicking on the 'Go' button has undertaken a task in the structrue event and also set up something in the queue to actually update the value of the variable.  Sounds good?

    This is the simplest example I could do for this problem that has emerged in vi a lot larger and more complex.  Any help is appreciated.

    With our thanks!  Devon

    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

    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', <> )
