How to use WITH Clause of Apex classic report

Hello.

I use Apex 4.2.1 on mod_plsq and Oracle 11 g 3.

I need to create a report classic usiing a WITH clause in the SQL report.  Apex keeps throwing the error 'CAN finf SELECT statement.

I then wrapped my report query in an envelope, SELECT * clause.  Apex then raises an error you need to use a variable LONG.

How is - a uses a WITH clause in the report query.

Here is my report query:

SELECT *.

Huh?  How can you put a SELECT statement in a procedure?  you return a cursor reference?

You create VIEWS.  You have three sections.  Give an opinion on each of them.  Test them with SQL Developer (or SQL * more)

Build from there.

In fact, it looks like you are trying to compare two tables"and return a DIFF

THINKING IN SETS

Use the WITH clause to build a 'virtual' table for EARLIER_NOTICE and a 'virtual' table for LATER_NOTICE.

Use FULL OUTER JOIN to compare the two.

THE FORMAT OF THE EXAMPLE:

select * from (
with w as ( .... )
,table_A as ( -- build the Virtual Table for EARLIER_NOTICE
SELECT *
 FROM
 V_URMT_COMPARE_NUCLIDE_DATA A1
   join W on (A1.urmt_btrs_pk, W.urmt_btrs_pk  and A1.earlier_notcie_id=W.earlier_notice_id)

--  old code
-- WHERE
-- 1 = 1-- why???
-- AND A.URMT_BTRS_PK     = (SELECT URMT_BTRS_PK FROM W)    --TO_NUMBER(:P202_URMT_BTRS_PK)
-- AND A.URMT_NOTICES_ID = (SELECT EARLIER_NOTICE_ID FROM W)   --TO_NUMBER(:P202_COMPARE_EARLER_NOTICE_ID)
,table_b as ( -- build the Virtual Table for the LATER_NOTICE

 select *
 from

 V_URMT_COMPARE_NUCLIDE_DATA B1
   join W on (b1.urmt_btrs_pk = W.urmt_btrs_pk  and b1.urmt_notice_id=W.later_notice_id)
)

--/*** NOW - WE COMPARE THE TWO ***/

    when B.urmt_btrs_pk is null then 'DELETED'
    else 'possibily updated'

ON (

  • How o use an icon in a standard report to display the details by using a hyperlink with APEX 5.0

    Hello

    I work with APEX 5.0.

    I would like a report (classic) display a report of details (also classical report) using a hyperlink, but not a "text-hyperlink" like 'click here for details'.

    Instead, I want to use a small icon which will occur the same result when you click on.

    It works fine, when the hyperlink is defined as text like: 'click here for details'.

    When I try to use an image, I don't get the desired result.

    Here's what I tried to Hare:

    1)

    Link-> Link attributes, then filled column: src = "& WORKSPACE_IMAGES. "" #ICON_NAME # "width ="40"height = 40 ' or img src =" & WORKSPACE_IMAGES. " "" #ICON_NAME # "width ="40"height = 40.

    = > no picture for the items in the column, but the link already created for each column of the remains (and works)

    2)

    Formatting of column-> HTML Expression, then filled: < img src = "& WORKSPACE_IMAGES. "" #ICON_NAME # "width ="40"height = 40" >

    = > the image appears for each column element, but the hyperlink is gone.

    Somone has idea how to use a picture/icon to have a hyperling in screens reported a detail?

    Thank you in advance for sharing your experience.

    Kimd cordially

    Hi Patrick,

    Link to the column-> then filled:

    Link text = #ICON_IS #

    Link attributes =.

    Target = this Application Page

    Page = 5

    Article 1 = P5_DEPTNO

    Value 1 = #DEPTNO #.

    Article 2 = P5_DEPARTMENT

    Value 2 = #DNAME #.

    Put this   in the link text not in attributes of link

    Remove the code from the link attributes.

    I don't have how to make it the way that describe you.

  • How to use 'with query clause"in DBadapter

    Hi all
    I need to implement a query "with clause" in oracle soa 11g bpel. When I put the query in the db adapter in pure sql, the schema is not generated correctly. The one you suggest a solution to my problem.

    Kind regards
    Kone

    Pure SQL will not work because it expects the first word in the SQL to SELECT (or INSERT, UPDATE, DELETE).

    If your query is WITH... SELECT...

    Try this:

    Delete everything before SELECTING. Copy and paste the XSD generated to another window. The SQL test may fail, but it simply means that he could not fill the column types in the SELECTION... OF the list. You can always make yourself manually edit the XSD (including in the wizard until you hit then). Then replace the WITH... remaining clause before SELECT it... If the XSD is crushed, the version that you saved in the other window and paste it over. Then press next and the runtime must still work.

    Keep in mind that SQL is very complex and difficult to scan entirely in the user interface. However, the minimum information needs DbAdapter is very limited; basically just the name and number of the columns that are returned. The XSD is supposed to be editable in the wizard, if the SQL code is too complex.

    Thank you

    I have a camera video camileo x 100. Can someone tell me how to use this unit on other software rather than the CRA? Won't codec, I use vegas video 8 and I try to convert you arc soft video converter, the only problem is

    1. I don't see video without audio
    2. regardless of the profile, I chose the converter does not give me the original size I shot the video
    3. the video is really badly coded and his jumps every time I press on play or make.

    Can you recommend some sort of software where I can convert these files and always keep it without loss?

    I think that it is a terrible problem! Why do you make a camera where you can not even change freely with a versatile codec? The arc soft video demo edition is low and in my opinion it is not supposed to buy a camera with these limited edition modes

    I would be really appreciated if someone could give a suggestion for a converter that can be used!

  • How is used with fx i18n resources: include?

    I can't seem to get bundles of resources working with fx: include.  This old post suggests it should work, but I'm running into two different errors.  I downloaded a very simple example here:

    https://DL.dropboxusercontent.com/u/8788282/sample-app.zip

    The example has everything set up the way I expect to work.  When I open "MainView.fxml" with SceneBuilder (7 bundled JRE), I get a MissingResourceException.  When I try to run "SampleApp" using JDK8-b111 I get a NullPointerException.  In the second case, it seems that fxmlloader might be passing a null to ResourceBundle ClassLoader.

    Does anyone know how to use beams of resource with nested views?  The Introduction of to FXML. JavaFX 2.2 docs silence resources fx: includes, but does not explain how it is supposed to work.

    A possible workaround is to make sure the ResourceBundle you go to your main FXMLLoader is not loaded by the system class loader. I think that the best way to proceed is to wrap the resource group, you get in the usual way in a trivial wrapper implementation. Something like this:

    import java.io.IOException;
    import java.util.Enumeration;
    import java.util.Locale;
    import java.util.ResourceBundle;
    import java.util.Set;
    
    import javafx.application.Application;
    import javafx.fxml.FXMLLoader;
    import javafx.scene.Parent;
    import javafx.scene.Scene;
    import javafx.stage.Stage;
    
    public class ResourcesTest extends Application {
    
     @Override
      public void start(Stage primaryStage) throws IOException {
           ResourceBundle resources = new ResourceBundleWrapper(ResourceBundle.getBundle("resources.Resources"));
           System.out.println(this.getClass().getClassLoader());
           System.out.println(resources.getClass().getClassLoader());
           FXMLLoader loader = new FXMLLoader(getClass().getResource("ResourcesTest.fxml"), resources);
           Parent root = (Parent) loader.load();
           Scene scene = new Scene(root, 300, 120);
           primaryStage.setScene(scene);
           primaryStage.show();
      }
    
      public static void main(String[] args) {
           launch(args);
      }
    
     // this class effectively does nothing, but it will be loaded by the
     // application class loader
     // instead of the system class loader.
      private static class ResourceBundleWrapper extends ResourceBundle {
    
           private final ResourceBundle bundle;
    
           ResourceBundleWrapper(ResourceBundle bundle) {
                this.bundle = bundle;
           }
    
           @Override
           protected Object handleGetObject(String key) {
                return bundle.getObject(key);
           }
    
           @Override
           public Enumeration getKeys() {
                return bundle.getKeys();
           }
    
           @Override
           public boolean containsKey(String key) {
                return bundle.containsKey(key);
           }
    
           @Override
           public Locale getLocale() {
                return bundle.getLocale();
           }
    
           @Override
           public Set keySet() {
                return bundle.keySet();
           }
    
           }
    }
    

    The simplest workarounds is may be possible, but I don't see one right now...

    I was able to achieve using the linl. I created a link on the col_id and it redirected to itself after you set the value of col2_id. I also changed the style of the button link and so col1_id looks like a button.

    However, I was interested to know if we can achieve this with a radio button and use the update form the Report2.

    You mean like this? It is very simple to implement using dynamic measurements.

    1. Add a column of radio group to the main report:

    select
        apex_item.radiogroup(1, d.department_id) rbg
      , d.*
    from
        oehr_departments d
    

    APEX 5.0, apply a static ID "rbg" to the column of radio group.

    2. create a hidden page unprotected element to maintain the value of the selected radio button to use as a filter in the detailed report. In the example, it is P31_DEPARTMENT_ID.

    3 refer to the element of filter in the WHERE clause of the report detail:

    select
        *
    from
        oehr_employees
    where
        department_id = :p31_department_id
    

    Set the Items property of the Page to send in the definition of report P31_DEPARTMENT_IDretail area.

    4. create a dynamic action of change on the Group of radio buttons:

    Event: Change

    Selection type: jQuery Selector

    jQuery Selector:td[headers="rbg"] input[type="radio"]

    Real Actions

    Seq: 10

    Action: Set value

    Type of value: Expression of JavaScript

    JavaScript expression:$(this.triggeringElement).val()

    Selection type: Article (s)

    Point: P31_DEPARTMENT_ID

    Seq: 20

    Action: Discount

    Selection type: Region

  • Using trigger ('apexrefresh') on a classic report

    4.2.2.00.11 RAC-11.2.0.3 apex.

    With the help of Jquery UI make a popup HTML region dialog box. 2 hidden elements exist in the area of the dialog box. A classic report is a region of the child in the area of dialogue - and use the 2 items hidden as report/SQL variables.

    JavaScript is used to set the values of the 2 hidden items, display the pop-up dialogue window and trigger an update of the classic report.

    Only the shutter button does not work. Which, from my Google search should work.

    The classic report starts with 2 divs. The 1st div id is generated, Apex e.g. report_ < number > _catch. The 2nd div (class uReportContainer) contains the id that I assigned the classic report, for example < regionID > report_.

    Triggering a refresh on each region fails to refresh the report itself. I.e. after does not result in a discount or other identifiers div:

    $('#<divID>').trigger ('apexrefresh');

    What is the identifier (or JQuery selector) to use for a classic report? Or what I am doing wrong?

    Workaround solution - I use a call to the pagination of the classic report in my Javascript instead of the update. For example

    apex.widget.Report.Paginate ('< identifier >', {min:1, max: 100, read: 100});

    It seems to work very well. But I prefer the refresh method and not a hack. :-)

    Strange sounds. I've been watching the code widget.report.js etc, but really, it's pretty basic. There is nothing wild in there. When he realizes it "report_" + id + "_catch" targets and fires before and after the events of refresh it. You can try to trigger an update on this item and see if it works?

    I have a classic report that has an element of control as the first column. I would like to put an element of the checkbox in the header, line when what it is supposed to set the element of the checkbox in all State lines. Something like in components shared APEX / links / edit the grid.

    Is this possible to do? TIA.

  • How to use the clause type conditionally create new lines

    This question is just for learning - no object other than to start real world to create versions of some queries known to learn how to measure the performance of the MODEL clause clause of the MODEL versions.

    The question is: How can you write a STANDARD clause that pivots (updates) ONLY the lines that actually need to rotate and do NOT change the lines that have no value and cannot be rotated.

    I found a good site that has about two dozen example articles on different pieces. This first link is the beginning of the series.

    SQL features tutorials - Clause TYPE

    http://www.sqlsnippets.com/en/topic-11663.html

    This link is to a clause of FAQ of BluShadow MODEL version "how to convert rows to columns."

    Line - MODEL method string

    http://www.sqlsnippets.com/en/topic-11987.html

    The solution to this link uses this line of source:

    POSITION KEY VAL

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

    R08 0 v1, v2, v3,.

    and this result set:

    POSITION KEY VAL

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

    R08 1 v1

    R08 2 v2

    R08 3 v3

    The reason why it produces that result set is this clause of the statement of MODEL

    RETURN THE UPDATED LINES

    If you comment on this article, you will see that the original lines are all in position 0. This means that the solution reproduced EACH SOURCE LINE even if there is only one item in the list of values.

    Thus, even a line source with a single value (for example, the r01 'a') will be updated and updated this line is returned.

    For a large number of data sources with only a few lines that actually need to rotate it would be a great performance of infringement.

    This is the sample data source

    with t as (button 1, 'a' value 'abc' col2, col3 'def' of the double
    Select Union all 2, 'b', 'ghi', 'jkl' from dual
    Union all select 3, 'c, d, e, 'mno', 'pqr' from dual.
    Union all select 4, 'f', 'stu', 'vwx' from dual
    )
    Select the key, value, col2, col3
    t

    KEY, VALUE, COL2, COL3
    1, a, abc, def
    2, b, GHI, jkl
    3, "c, d, e, mno, pqr.
    4, f, stu, vwx

    Lines 1, 2 and 4 only have a value of (a, b, c respectively.

    Only line 3 must rotate. It contains "c, d, e" and which must become 3 lines in the result set

    Value of the key, col2 col3
    1 an abc def
    2B ghi jkl
    3 c mno, pqr
    3 d mno, pqr
    3 e mno, pqr
    4 f stu vwx

    The nut of the problem is that if the clause 'RETURN UPDATED ROWS' is used, then the lines 1, 2 and 4 must be updated in order to be returned in the result set. And if this clause is NOT used, then line 3 must be updated by 'c', d, e 'c' and two new product lines: one line for a ' and one for 'e '.

    How can you do this with the TYPE clause without the help of the clause "Return LINES UPDATE"? I don't have a solution to sample showing what I tried because I can't understand what it takes to even try.

    I have a solution that uses "RETURN UPDATED ROWS" but I want to compare this performance to the exercise, when this clause is NOT used.

    We ask BluShadow to add the solution of MODEL clause to this FAQ with other similar solutions.
