List of values when using xquery with links?

Hello

What is the best way to build something like:
collection('test.dbxml')/tree[type=('a','b','c')]
with XQuery variable when it is unclear how many entries will be in the listeType beforehand? I would like to somehow put ('a', 'b', 'c') in a context of query as a variable to something like:
collection('test.dbxml')/tree[type=$var]
So, avoiding the risk of strengthening of string concatenation queries.

Hello

Java example:

XmlResults res = manager.createResults();
res.add(new XmlValue("a"));
res.add(new XmlValue("b"));
res.add(new XmlValue("c"));
....

xmlQueryContext.setVariableValue("myVarName", res);

  • How to complete the list of values when loading screen

    Hi all

    I have a list of values based on another field (ANOTHER_FIELD).

    for example
    Select the value d, r
    from table_name
    where id =: ANOTHER_FIELD;

    ANOTHER_FIELD has a default value.

    But when the screen is opened to the list of values does not have the default value and the values list is empty.
    Just when it is filled with submission of the form, the list of values.

    Please tell me how can I complete the list of values when loading screen.

    Thank you!

    Hello

    It depends on how you have defined the default value for ANOTHER_FIELD.

    I always set my default settings using a calculation, that runs before header, on the element that defines the value using a static assignment, but to ensure that the calculation is dependent on the order of the day being NULL - try this

  • Select the first value in the list of values when running in poplist

    Hello
    IM using forms 6i. I filled the poplist by request. But what I need, I want to choose the first value in the list of values when running...

    That is to say, during execution, the poplist should have chosen its first value in the list of values.

    Concerning

    WHEN CREATING a RECORD of the block of the list item or after the filling of the list item, you can write

    : my_list_item: = GET_GROUP_CHAR_CELL ('my_list_item', 1); / * If the data type of the item in your list is character.*.

    Here, instead of 1, you can give any clue... 1: value to the first list item position

  • Using XQuery with PL/SQL, link the Variable

    I am only able to find an example of use of xquery with pl/sql.

    [http://www.comp.dit.ie/btierney/oracle11gdoc/appdev.111/b28369/xdb_xquery.htm#CBAEEJDE]

    Why is what they show only using bind variables? It's the only way it should be used, it provides a performance gain more simply by using the crossing clause and a passing beam a PL/SQL variable? I'm looking to implement a solution for my company using Xquery in PL/SQL. I am concerned that these procedures will be called during a flow of the user interface and performance it must be as soon as possible.

    A PL/SQL variable, column, or the output of another operation would be all be equivalent to a connection variable that PL/SQL compilation is concerned. Which would be bad practice would be to build in XQuery with the predicate hardcoded in the XQuery operation whenever the XQuery query has been run.

  • wrong values when using NOT EXISTS

    Greedings,
    I have a problem when using NOT exists in a query
    for example, in the following query im trying to recover the unit costs (column) with the code (column), '55210' if the order of this unit cost is included in another table and the order of the 2nd table does not exist in a 3rd table.
    Thanks in advance for any advice
    SELECT c.unit_cost
           from amounts c
           WHERE trim(c.code)='55210'
           AND EXISTS (SELECT * from order_record a where trim(c.order_no)=trim(a.L1))
           AND NOT EXISTS (SELECT * FROM invoice_voucher b,amos_order_record a WHERE Trim(b.F1)!=trim(a.L1)

    You don't seem to have linked one of your tables in NOT EXISTS (i.e. invoice_voucher b, amos_order_record one) to the parent table (amount c)

    Hi Rita

    Okay, now gotcha. Indeed, I think that if I did that, I would make two changes of parameters.

  • Problem with list-of-values while using Oracle ATS

    All by registering a fact oracle application using Oracle ATS, whenever I click on a button LOV and select a value from the list, I am being disconnected from the application. Is this a common occurrence? Let me mention here that LOV works very well, it's only when recording with the ATS that I find this question.

    Could someone give me a solution to workaround with LOVs in ATS?

    The LOV works very well in OATMEAL, I use EBS form it works fine, maybe there an installation problem. Alternatively, you can manually include LOV by action forms are trying.

  • Data merge problem - bad values when exporting PDF with "All folders" only

    Hi - I have the weirdest problem with InDesign: I use merge data from .csv to create a deck of cards (9 per page), and when I export to PDF from the data merge Panel, one of my field has erroneous data: it uses values from previous records and which repeat.

    What is strange, is that when the noticed, all right. Is also very good if I create a merged Document and PDF export. Is also very good if I export to PDF using just the range of entries it is play: I don't get that wrong data if export as PDF, "All records" in the data merge Panel.  Very frustrating!

    Someone saw? I feel that my data is ok, if the export of individual records is very well...

    Cheers for any help.

    Thank you! Which has me on the path to what looks like a fix...

    Copy all the fields in a new file does not solve the problem - the same behavior, but after the start of charges, I started to adjust the sizes of the fields and stumbled upon a possible solution.

    A field that trouble is a text box for a single digit, if limits are quite small. The name of the field for example placeholder. > is bigger and complained of cut-off text.  Increase the limits of the text box to be at least the size of the reliable placeholder text solves the problem. It decreases the size of a single digit... back of the problem.

    How weird.

    Thanks Peter.

  • set at runtime (color, pattern) using srw package-list of values to use

    Hi to you all,.

    Sometimes, in the reports that we want to set color, pattern, etc... a filed during execution.
    We can do this by using the package-srw.

    colors are identified by their names or RGB values
    to retrieve the value of their name or RGB, I use conditional formatting "tool" or "ownership" of this field.

    for example:
    -Automatically generated reports generator.
    If (: A = 'blue')
    then
    SRW.set_foreground_border_color ('r0g75b100'); - light blue
    SRW.set_foreground_fill_color ('r0g25b75'); - medium-blue
    SRW.set_text_color ('r0g0b50'); -darkblue
    end if;


    However,.

    is their a list with the names of valid for use with model
    SRW. SET_FILL_PATTERN ('pattern');
    ?

    Greetings,
    E.

    Hello

    .. Another method is to move your mouse over the fill pattern in the "fill pattern Palette. The name of the models is displayed in the status bar

  • Select list first value problem using AJAX

    Hello

    I've implemented the list of selection in AJAX by allusion to Denes Kubicek - http://apex.oracle.com/pls/otn/f?p=31517:119:3737449055187298:NO. I have only 2 selection lists. The AJAX functionality doesn't quite work for the first selected value in the list select a first. I get not all values in second SelectList when the first value is selected in the first SelectList. It works very well for the rest of the values in the first selection list. I kept a few warning messages to debug JavaScript. I think the problem is with the function below,

    get var = new htmldb_Get (null, html_GetElement('pFlowId').value,
    = States_In_County', 0);
    Get.Add ('F109_AJAX_COUNTY', html_GetElement (pThis) .value);
    gReturn = get.get ('XML');

    For the first value in the first list of Select, gReturn.getElementsByTagName("option").length; Returns 0.

  • VirtualAlloc fails when using MEM_RESERVE with MEM_LARGE_PAGES.

    VirtualAlloc is called with the combination of MEM_RESERVE and MEM_LARGE_PAGES, the call always fails. According to research on the web (in particular, http://blogs.msdn.com/b/oldnewthing/archive/2011/01/28/10121300.aspx), the reason is that the OS is not able to guarantee that we will find a contiguous physical memory space of 2 MB.

    However, it not seem desirable to prohibit purely and simply this problem on modern computers which can often have 8 GB or 12 GB of physical memory, which should mean that it often takes a reasonable amount of pages of 2 MB available. Reserving a large amount of virtual space and no commitment necessary is a very useful technique, and its overhead is reduced by using large pages (not to mention that the memory itself should run faster because of less narrowly BLT and Associates page walks). Commit all the memory in the front is very undesirable because only a fraction of this memory is perhaps necessary (normally, the operating system allocates only the committed memory when it is consulted, but apparently it is also disabled for large pages). However, using realloc() or similar techniques may invalidate all previous pointers to areas have been attributed, which makes them impractical for certain tasks.

    In addition, once VirtualAlloc was called once with MEM_RESERVE. MEM_LARGE_PAGES, any subsequent calls to VirtualAlloc with the same program also appear to fail with an error, even if they work fine without it. This seems to be a bug in the API.

    Would it not possible to allow MEM_RESERVE without validation for MEM_LARGE_PAGES (and the associated MEM_COMMIT later) at some point in the future?
