  Hi all
  
  Maybe this is a stupid question. But why get this error with a report of the IR? and what is the solution for this. Please help me with this.

  Oh... And I also have a blob column... If the format is not given, the table is very good... but happen to get this error only when the BLOB download format is given.
  
  Thanks and greetings

  Hello

  I implemented a small suitcase of test on apex.oracle.com and I get the error even if I use the download format.

  I have a table
  test_blob (identification number, name varchar2 (10), blobcont blob)

  If I create IR as

    select
      id,
      name,
      blobcont
    from test_blob
  

  and then I set the download format I got the error.

  If you want this to work you need to change your query to

    select
      id,
      name,
      dbms_lob.getlength(blobcont) blobcont
    from test_blob
  

  And there still define download for blob on column blobcont format.

  Kind regards

• Special characters are not displayed using the report query

  I run my ad page APEX reports BI using apex_util.download_print_document (see below).
  
  Looks like it's stripping on the '+' in the report during the display. It displays correctly in the XML file.
  I even tried encoding with SELECT max (replace (I1.alpha_grade, ' + ', '% 2B')). This displays the '% 2B' instead of the ' + '.
  Any ideas?
  
  
  () apex_util.download_print_document
  p_file_name = > l_form_description,
  p_content_disposition = > 'attachment ',.
  p_application_id = > v ('APP_ID').
  p_report_query_name = > nvl (l_report_query_name, l_form).
  p_report_layout = > l_layout,
  p_report_layout_type = > 'rtf ',.
  p_document_format = > v ('P507_OUTPUT_FORMAT'));

  Bob,

  Try

  REGEXP_REPLACE ( i1.alpha_grade, '\&\#43;', '(+)' )

• Step failed in New Thread does not display in the report

  Hello

  I call a sequence of sub in a 'new topic '.  A step inside this sequence of subroutine fails.

  The end result is the Test failed because it is supposed to be, but the step failed does not show.  (I show not only failed in the report).

  Can it be fixed?

  Thank you

  Rafi

  It is correct. If you look at the entry Point of the execution of the process template, you'll notice that once completed execution of the main sequence, the generation of reports and other things start.

  If spawn you a sequence in the new thread from the main sequence, MainSequence could finish before the subsequence ends its execution and the results of the sous-suite propagate to MainSequence. So as Ray mentioned, you can force the MainSequence expect the subsequence full run using a queue time.

  See attached screenshot and/or example:

  

• How the setting to display in the report?

  Hi all... I have a multi select parameter in a report.
  
  Generally, we use this statement to initialize the model parameters
  
  <? param@begin: ParameterName? >
  
  and to show that we use: <? parameter_name? >
  
  But it's good for the parameters a unique value
  I have a multi selection setting, I need to show all these values(suppose 3) in the title of the report. (They may not be included in the SQL in a column)
  How to achieve this?
  
  Thank you very much in advance!

  You can use the same for multiple selection of values also

• Couldn't able to reduce the size of the image while storing in the report

  Hi friends,
  
  Im trying to save the image in my table, so that these are the steps that I follow...
  
  First, I created a table:
  

  CREATE TABLE "A_IMAGES"
  (
  "IMAGE_ID" NUMBER(10,0) NOT NULL ENABLE,
  "FILE_NAME" VARCHAR2(4000) NOT NULL ENABLE,
  "BLOB_CONTENT" BLOB,
  "MIME_TYPE" VARCHAR2(4000),
  CONSTRAINT "A_IMAGES_PK" PRIMARY KEY ("IMAGE_ID") ENABLE
  )

  After this sequence, relaxation and the procedure,.
  
  Let me show you the procedure
  

  create or replace PROCEDURE "DISPLAY_IMAGE"
  (
  inID NUMBER
  )
  AS
  vMIME VARCHAR2(48);
  vLENGTH NUMBER;
  vFILENAME VARCHAR2(2000);
  vBLOB BLOB;
  BEGIN
  SELECT MIME_TYPE, BLOB_CONTENT, FILE_NAME, DBMS_LOB.GETLENGTH(BLOB_CONTENT)
  INTO vMIME, vBLOB, vFILENAME, vLENGTH
  FROM A_IMAGES
  WHERE IMAGE_ID = inID;
  owa_util.mime_header(nvl(vMIME, 'application/octet'), FALSE);
  htp.p('Content-length: ' || vLENGTH);
  owa_util.http_header_close;
  wpg_docload.download_file(vBLOB);
  END;

  Everything worked fine, but the following error occurs when im trying to insert an image into a table with a browse button.
  

  ORA-06502: PL/SQL: digital or value error: character of number conversion error

  The error above if I include the following line in the source code of my region report...
  

  ' < img src = "#OWNER #." DISPLAY_IMAGE? inID =' | NVL (IMAGE_ID, 0) | "" height = "50" width = "50" / > "IMAGE

  mainly, I added the above line in my source region only query for the image (size setting)...
  
  If I give the report source region coding as the means below, it works like a charm
  :)
  

  SELECT FILE_NAME,IMAGE_ID,
  dbms_lob.getlength("BLOB_CONTENT") "IMAGE" 
  FROM A_IMAGES
  ORDER BY FILE_NAME

  But what is the problem with the above code means, as he worked successfully and I can also see the images in the report, but each image is looking too big...
  
  In order to reduce the size of the image that I gave this line,
  

  ' < img src = "#OWNER #." DISPLAY_IMAGE? inID =' | NVL (IMAGE_ID, 0) | "'" height = "50" width = "50" / > ' IMAGE

  but if I gave ways online, error is occurring as the image does not store in a size appropriate for the table...
  
  But there, I noticed one thing,
  
  dbms_lob.getlength ("BLOB_CONTENT") 'IMAGE' is normally in a type of NUMBER , and it works very well...
  
  But instead of dbms_lob.getlength("BLOB_CONTENT") 'IMAGE', if I replaced it with *' < img src = "#OWNER #." DISPLAY_IMAGE? inID =' | NVL (IMAGE_ID, 0) | ' ' ' height = '50' * width = "50" / > ' IMAGE means, it is converted to a string...
  
  I think mainly for that alone, it's show error...

  I created a new page 3 which shows how to use the CSS (in the header HTML page) to control the scaling of the images displayed in the reports using BLOB support declarative.

  However, you really need to use generated thumbnails to the right size instead of scaling of the images in the browser. If the images used in your demo are for guidance, so they are waaayyyy too big to use in this scenario. This just kill performance on your web server and database and unnecessarily consume massive amounts of band network bandwidth. Your DBA, system administrators, ISPS and users will be very unhappy.

• How to display a BLOB (Image) in a report of the EBS?

  User has requested to add a Logo image to a report called the E-Business Suite (EBS).
  
  The image is currently stores in a BLOB column.
  
  How can I make the image to display in the report?
  
  Thank you!

  I don't see why it wouldn't work on Unix. Each element in the layout is a source based on a column in your query (in the datamodel). It doesn't matter if it's Windows or Unix.

  Reports done automatically if you use the wizard. If you change an existing report, you need to add the column (in the datamodel) and element (in the layout) yourself.

• How can I get my Teststand report to display only the data of the latest iteration of a loop DoWhile ONLY stage?

  Good so I a DoWhile loop with a numeric value to test.  The loop will run 10 times.  I want only the status of success/failure of the test of the numerical value of the last iteration of the loop is displayed in the report.  I don't like on the other iterations.  Help, please!  Thanks in advance I think that this can be accomplished with the recall of ModifyReportEntry and fancy logic...

  Thanks for your comments everyone.  I ended up changing the reportgen_txt.seq to identify during my test was in a loop (by setting an additional result in the different stages of my comment loop-step to say "Record last loop.".)  Once this indicator lies in the ResultList I turn to reportgen_txt, I have to loop through all the ResultList entries and if the current entry has the same name and the "record last of loop." as a previous entry, I delete the previous entry and store the current.  All this way, I have to do is to set a flag in my test sequence, and if when debugging, I want to see all the data for all the iterations, I just remove the flag.

  The reportgen_txt.seq include:

  C:\Program NIUninstaller Instruments\TestStand 2010\Components\Models\TestStandModels

  I'm not worried about the time constants on my generation of report and I am not limited to stress strict memory so this seemed like the best way for me to do what I had accomplished.  I'm sure there are better ways, but it seemed simpler than the generation of report definition to be disabled and then enabled...

• How can I connect a Labview XY (cluster of 2 tables) TestStand 2010 SP1 chart and do appear correctly in the report?

  Patterns of data record TestStand 2010 SP1 default shared this cluster in two tables stored as binary data, resulting in two graphs displayed in the report: one for data and one for X data Y. We need the elements X and Y, couples on the same graph. This cluster is marked for logging as a step output variable. It seems possible to add a table "PROP_XYGRAPH" (similar to the PROP_ANALOGWAVEFORM) to the schema to simplify the other treatment after the database record, but how can we get the Builder, to accept this type of data is displayed correctly? XY graphics come from LabVIEW 2013 SP1 exclusively as a cluster of two matrices, usually between 500 and 1,000 items long.

  Hi all

  I am bulding an open source oracle apex app to track aircraft using ADS - B technology.

  I have somes types of units.  for example (kilometers, miles, knots, feet and metres).

  So, in the report of the IR, I want pick capable of showing a unit in time.

  For example

  Radio Group.

  Ground speed: (*) km/h () Mhp (Knt)

  Vertical speed: (*) ft/s (m/s)

  Can anyone help to build a code or point a direction to get above result?

  I tried already a thread, but did not work.

  Apex: Display/hide report column with Radio button. 2 cents to Oracle by Christoph

  Display / hide column IR dynamically

  
  

  I have a limited knowledge of Oracle APEX.

  I am bulding an open source oracle apex app to track aircraft using ADS - B technology.

  I have somes types of units.  for example (kilometers, miles, knots, feet and metres).

  So, in the report of the IR, I want pick capable of showing a unit in time.

  For example

  Group of radio buttons.

  Ground speed: (*) km/h () Mhp (Knt)

  Vertical speed: (*) ft/s (m/s)

  There are different ways to do this. Probably the easiest would be:

  1. Create lists of values (LOVs) for units.
  2. Add the elements of the Group of radio -based unity LOVs report interactive region (IR), by specifying one of the units as a default value.
  3. Present the radio group via the Items property of the Page to send IR region.
  4. Create multi-column report for each metric combination / unit.
  5. Control the display of the report columns (applies to IR, but also classic report columns) conditionally using value of element in the Expression 1 = Expression 2 conditions Expression 1 is the group element of relevant radio and Expression 2 unit LOV value corresponding to that used in the column of the report.
  6. Add a dynamic action on the evolution of the components of the radio to refresh the IR region.

  A less obvious approach would also use LOVs, group radio elements and dynamic action of change/update as above, but only have one column for each measure in the report. The column value is calculated using an expression based on the value of the radio group, for example:

  .
  .
  .
  /* Assuming base speed unit is km/h */
    ground_speed
  * case :p1_ground_speed_unit
      when 'mph' then 0.621371
      when 'kn' then 0.539957
      else 1
    end ground_speed
  .
  .
  .
  

  The unit could be indicated in the column heading in the report referring to the element of the device by using a substitution of static text string:Ground Speed (&P1_GROUND_SPEED_UNIT.)

  I looked at the application.

  Do you want to go to the report page after click on the report button? If it is, your button to submit the page. Then, you need a branch to access this URL. By submitting the page, your value should be set at the session.

• Display all the fields in a column

  Hello
  
  I have a standard report and on the one hand of the columns (status), I have 3 domains. lets say 'won', 'lost', 'draw' with their respective w, l, d codes displayed in the report.
  When I try to insert a new record, it displays only the 'draw' (d) case. the other two cases also get inserted but does not appear on the report. the research too does not detect the other two.
  
  How can I get the other two fields also appear in the cloumn (status) on the report on the home page.
  
  
  Thank you
  Neya

  With a dynamic lov, you want your column display or "D" is the name (which is meaningful to the user) and the column back or 'R' is the one that will be the value stored in the database column.

  So, you can

  D     R
  --------
  Draw  D
  Won   W
  Lost  L
  

  I don't know why the Select list that displays on the form (using the dynamic LOV) displays all the values that are output when you run the same query on the DB schema.

  Maybe try to create an another NEW LOV in APEX shared components and see how it goes?

• hidden lines in export the report to excel

  Hello
  
  If there is a report with the hidden fields, the fields will be displayed when the report is exported to excel.
  
  Is it possible to prevent this?
  
  The setting in pref.txt ExportGroupSortedItemsAsBlank does not seem to be an excel report. In both cases, we have already defined as 1.
  
  Thank you.
  Leah

  Hi LEA
  Sorry you can not remove the export of hidden lines. The reason why they are generally there to sort and without them the data would be a mistake, so you cannot remove their export. Inside the discoverer, they are only is removed from the display, they are still used in the SQL code and will always be used in exports.

  Sorry about that

  Best wishes
