  Chambers,

  You can use wwv_flow_utilities.array_element to avoid any no_data_found. The function does not raise any errors. For example, for the line which only have a value of table when you wait 2, it can be useful.

  EXECUTE IMMEDIATE 'insert into table_name@Schema1 (col1,col2)
      values (:1,:2)'
      USING
        wwv_flow_utilities.array_element(v_data_array,1),
        wwv_flow_utilities.array_element(v_data_array,2);
  

  Kind regards

  problems with windows install

  I am trying to install flipshare on my computer. I have vista. When I download the program and try it to install it, I get 2 errors. They are as follows...

  "There is a problem with the windows package install." A script required for this install to complete could not be run. Contact your personal support provider or the package. »

  Then when I click OK, this error comes in... "It seems you have an incomplete or corrupt installation. Please use Add/Remove programs to uninstall the previous version. »

  I don't have a previous version of flipshare on the computer, I deleted it and it isn't on the list of programs.

  I have installed all updates.

  I got a support to scan the computer and got a Windows Resource Protection found corrupt files but was unable to solve some of them.

  Does anyone have suggestions as how to do to solve this problem?

  I downloaded Speedy PC Pro in the hope that they could help and he did not. They resumed even remotly and could not understand it :(

  Any help? :(

• Query of the region gets no data found

  Hi all
  
  I have a region that is of type "SQL query". This area is also a button 'apply update '. There is a validation of the page that looks up a value in a shuttle that goes off when you press 'Apply update'. Sometimes, when the button is pressed and the validation fails the region return that the no data found message as defined in the attribute for the region, other times reports page when the failure of the validation of data which has been in the region until the button is pressed just stay there, as it should.
  
  Why I get such different results when validation fails? Why do I sometimes get "no data found" and other times I get the data in the array returned by the SQL query?
  
  A couple of things to point out,
  
  (1) the table gave in, the sql query will always return Row (s)
  
  (2) the sql query is NOT dependent on the values of page defined level.
  
  (3) the sql query is simple, similar to...
  
  Select *.
  of my_custom_table
  my_column asc order

  Is a global temporary table... but it is defined as "on commit preserve rows", my data must therefore be kept for my entire session, even if it wasn't, it still does not explain the sporadic "no data found", unless the APEX is somehow sometimes change the session and I'm not aware of it...

  Exactly what APEX - and any other web technology using connection pooling- done.

  Replace the TWG with a collection of the APEX. You can define a view of the collection to match the name of the existing table, the column names and data types.

  How to activate the search function.  I get no match found when I search for words on the scanned PDF document

  A scanned document is just an image; even if it contains text, it is not searchable.

  Put text in a scanned image available, you will need to perform the recognition of text (OCR), which can be made with Acrobat, but not the free player.

• Interactive report: "no data found" when first loading

  Hello
  
  I use APEX 4.0 with Oracle 10 g r2 under Windows XP Pro SP3.
  
  I have an interactive report and a menu with a few items to filter the report.
  
  The problem is that the first time I load the page, the report shows "no data found", when I reboot, it works. If I navigate to another page and then I go back to the page of report, it also works.
  
  There seems to be a problem with session state, but I can't found how do works, even using an AJAX setItemInSessionState() function.
  
  The query depends on the values of the elements:
  

  select
       SPAT_ID, SPAT_ACCL_NAME, SPAT_AREA_NAME, SPAT_CLASS, SPAT_NUMBER, SPAT_PT, SPAT_TYPE, SPAT_STATUS,
       round(SPAT_CUMUL,2) as "SPAT_CUMUL"
  from
       SPATIAL_POINTS
  where
       upper(SPAT_AREA_NAME) LIKE upper(:P3_FILTRE_AREA_NAME)
  AND upper(SPAT_CLASS) LIKE '%'||upper(:P3_SPATIAL_CLASS)||'%'
  AND upper(SPAT_NUMBER) LIKE '%'||upper(:P3_FILTRE_NUMBER)||'%'
  AND instr(upper(:P3_SPATIAL_POINT_VALUES),upper(nvl(SPAT_PT,' '))) > 0
  AND instr(upper(:P3_SPATIAL_TYPE_VALUES),upper(SPAT_TYPE)) > 0
  AND (:P3_FILTRE_ACC_NAME IS NULL AND spat_accl_name IS NULL OR CASE WHEN :P3_FILTRE_ACC_NAME = '%' THEN nvl(spat_accl_name,'_NULL_') ELSE :P3_FILTRE_ACC_NAME END = nvl(spat_accl_name,'_NULL_'))

  I've implemented on apex.oracle.com, if you find the time to take a look: http://apex.oracle.com/pls/apex/f?p=4550:1
  You should get a "no data found" the first time the page loaded.

  Made the trail 30 for all applications begin as soon as you download the trial version of the creative cloud? Or the test for Photoshop 30 days begins the day you install Photoshop regardless of when you downloaded the trial version of the creative cloud and installed Lightroom?

  It is the date of installation that counts, but sometimes the 30 day trial may finish early, especially if you change something on your system (for example, hardware, clock, etc. system restore).
