• Collection of Apex of access that is created as part of the wizard to load data

  Hi all

  I tried to figure out how to access the Collection of Apex that stores data related to the data load.

  Please need documentation that may help understand the process.

  Hi all

  In the upload form, we have 4 Pages / screen, each screen has an associated collection of Apex.

  Below the Apex Collection are associated with Pages

  "SPREADSHEET_CONTENT" - page 1

  "PARSE_COL_HEAD" - Page 2

  "LOAD_CONTENT" - Page 3

  "LOAD_COL_HEAD" - Page 3

  "FIN_LOAD_CONTENT" - Page 4

  What interested me was in the PARSE_COL_HEAD that lists the columns that are not mapped on the 2nd Page, (data map).

  So now that we know the collection of the Apex, I will ask the Collection:

  Select count (c002) in the CNT from apex_collections where 'PARSE_COL_HEAD' and C002 = collection_name = "DO_NOT_LOAD";

  If you want to see it working, I created an example on the link below:

• Collections of apex

  When I do a

  select * 
  from apex_collections

  I always get a 'no data found.' even though my request was told that there is indeed a collection of apex.
  
  For debugging purposes, what is the best way to see what is contained in a collection of apex at some point in time?

• From the APEX Collections out APEX?

  We have a system developed in the APEX that generates reports using plsql returning a query. These query parameters are passed using the APEX collection infrastructure. This allows you to run various reports and add them to the system by simply inserting the code in a table.
  
  Anyway, it was suggested that we might be able to schedule the report to run using the Oracle Applications and a concurrent request. What we'd probably do would be to a txt file using "immediate execution" of the spool and print it out. The next issue is of course to get the parameters set up with their respective values.
  I have tried this in the code and get an error:
  

  BEGIN
    wwv_flow_api.set_security_group_id(apex_util.find_security_group_id('OUR_WORKSPACE_NAME'));
    apex_collection.create_collection('XXTEST');
    apex_collection.add_members('XXTEST', p_c001 => apex_application.g_f01);
  END;

  This returns the error:
  

  ORA-01400: cannot insert NULL into ("FLOWS_030100"."WWV_FLOW_COLLECTIONS$"."SESSION_ID")
  ORA-06512: at "FLOWS_030100.WWV_FLOW_COLLECTION", line 288
  ORA-06512: at line 3

  Then... Is it possible, we can use the framework of collections of APEX to outside the APEX?
  
  
  Thank you
  John

  Yes,

  I was testing. Like, after you have created the session I chose v double ('APP_SESSION'), and he returned very well, so there is obviously more behind the scenes of transformation that takes place in APEX, so that the session available in the table of $ wwv_flow_sessions.

  Maybe you could just piggy back on a session that is new enough to be always available, but old enough that it is no longer used (through one of the points of view APEX).

• Error ORA-01445 tabular form on a Collection in APEX 5

  When I load a page with a tabular presentation built on a display of a collection to the APEX 5, I'm getting an ORA-01445: cannot select ROWID, or the sample, a view of joining without an error table preserved key.

  I create a view

  CREATE or REPLACE FORCE VIEWS test_coll_vw

  (

  C001,

  C002,

  C003,

  C004,

  seq_id

  )

  AS

  SELECT TO_NUMBER (c001),

  C002,

  TO_NUMBER (c003),

  TO_NUMBER (c004),

  seq_id

  Of apex_collections

  WHERE collection_name = 'TEST '.

  Then create a tabular presentation on the view with the primary key of the source SEQ_ID and primary key of the trigger existing through the wizard.

  Debug information shows the statement which is a failure:

  Select NULL NULL "CHECK$ 01", "SEQ_ID,' NULL 'C001', NULL"C002', 'C003', 'C004', NULL NULL NULL "APEX$ ROWID ' sys.dual union all select ' CHECK$ 01", 'SEQ_ID', 'C001', 'C002', 'C003', "C004", "APEX$ ROWID" in (select NULL "CHECK$ 01", "SEQ_ID", "C001", "C002", "C003", "C004", "ROWID" "APEX$ ROWID" (select).

  "SEQ_ID."

  "C001."

  "C002."

  "C003."

  "C004.

  of 'WPCAMS_APP '. "" TEST_COLL_VW ".

  ) APEX$ RPTSRC

  order of 1, 7

  ).

  These tabular forms worked up to 4.2, but they seem to fail at 5 APEX for upgrade or newly created pages one.  The generated query is identical between versions, but it seems that the underlying apex_collections view has changed between versions and the origin of the problem.

  Does anyone have a solution or workaround?

  Thank you

  Hi Phil,

  APEX 5.0 the definition of the view of apex_collection had to be changed for security reasons. This change introduced a regression with tabular form validations, when the table refers to this view. Tabular form declarative validations require the ROWID in order to restore your changed data after a validation failed, and for this reason, APEX is insert the IDENTIFIER in the query in a table. It is currently not possible when tables refers to the sight of apex_collections. We are looking at a solution to this problem, but for now the only way to get around this is not, in this case, use the declarative validation and use some custom validations or process.

  Kind regards

  problem

  I have a special case where I need to use a dynamic SQL code to populate a Collection

  (I'm still working on avoiding that...)

  According to the APEX Documentation, it seems that you can use right cursor number of DBMS_SQL.

  However, when I try, I get ORA-29470.

  ORA-20104: create_collection_from_query error:

  ORA-20104: create_collection_from_query ExecErr:

  ORA-29470: effective Userid or roles are not the same when the cursor was analyzed

  And if I open the cursor with "security_level = > 0", I get:

  ORA-29474: DBMS_SQL. OPEN_CURSOR failed. security_level 0 is not allowed.

  In regards to the APEX_COLLECTION using the number of cursor, it's a known bug?

  Any other comments/suggestions/response?

  Thank you

  Hello

  I encountered the same problem when upgrading a database from Oracle 10 g to 11 g. The latter has additional security to protect against the "misuse of cursor" or somesuch.

  Since you are using 4 Apex, you can work around the problem by using instead the CREATE_COLLECTION_FROM_QUERY_B (the 'B' is 'essential', it will make your code more quickly, too!), since this procedure allows to make the call as to bind the variable names and values, thus negating the need to use dbms_sql yourself. See docs here: APEX_COLLECTION

  A workaround for Apex 3 (and Oracle 11 g) is to open the cursor dbms_sql and loop through it, call apex_collection.add_members for each line. Obviously, this will be slower than the procedure in bulk, but at least you can avoid the ORA-29470.

• How to create a collection of apex to store and to loop through the values

  I couldn't find a simple example to do
  Apex 4.2
  
  I need to create a collection of the apex. I have a query that returns multiple roles for a user. I need to check to see if one of my values of point is within the collection, but I'm not sure how. So far, I have:
  
  Start
  APEX_COLLECTION. () CREATE_COLLECTION
  p_collection_name = > 'ALL_ROLES');
  
  Select count (granted_role) in the County of dba_role_privs where upper (grantee) = upper(:APP_USER);
  
  end;
  
  How would store the query results in the collection?

  Even shorter

  declare
    v_count number;
  begin
    if :P32_SUBMISSION_DATE is null
    then
      return false;
    end if;
    select count(*) into v_count
    from dba_role_privs
    where upper(grantee) = upper(:APP_USER)
    and  granted_role in ('SURVEY_SUID','SURVEY_JOB_SUID');
  --
    return v_count > 0;
  end;
  

  Note that with a combined function as count you will never get an exception no_data_found

  Hello

  Write the name of the collection always in capital letters
  >
  Appellation collections

  When you create a collection, you must give it a name that cannot exceed 255 characters. Note that collection names are not case-sensitive, and will be converted to upper case.

  Once the collection is named, you can access the values in the collection by running a SQL query on the view APEX_COLLECTIONS.

• Check the box of a CASE for a Collection of Apex statement

  Attempt to use a case statement to determine the day of the week in the field of LINEITEM_DATE2, then
  Place the REG_HOURS in the new columns in the collection representing the days of the week.
  The case statement below (in bold) just doesn't. I even tried when a simple and hardcode
  a value. So is it possible that way?

  P 8 JUNE 16, 10
  P 2 JUNE 14, 10

  6 8 P
  P2 8

  Hello Shelly,

  V_DATE's date , it means that you needn't to_date:

  CASE
  /*WHEN to_date(LINEITEM_DATE2, 'DD_MON_RR') = to_date(t_date, 'DD_MON_RR')*/
  WHEN LINEITEM_DATE2 = t_date
  THEN REG_HOURS
  ELSE '0'
  END as monday
  

  I guess that LINEITEM_DATE2 is of type date .

  If you want to compare without time then

  CASE
  /*WHEN to_date(LINEITEM_DATE2, 'DD_MON_RR') = to_date(t_date, 'DD_MON_RR')*/
  WHEN trunc(LINEITEM_DATE2) = trunc(t_date)
  THEN REG_HOURS
  ELSE '0'
  END as monday
  

  I also think that:

   p_c008 => monday,
  

  Must be:

   p_c008 => rec.monday,

  The code I used to add a colletion APEX will work perfectly and is as below
  
  -Initialization Collection PHASE_COLLECTION
  BEGIN
  IF THIS ISN'T APEX_COLLECTION. COLLECTION_EXISTS('PHASE_COLLECTION') THEN
  APEX_COLLECTION. CREATE_COLLECTION ('PHASE_COLLECTION');

  What I tried to use APEX_COLLETION to check the overlap between the date_range.
  The requirement is just to display a warning if the user adds a record to the new phase or update record of current phase may overlap between the order of phase together.
  Table PHASE_MEMBERSHIP script is
  
  CREATE TABLE 'PHASE_MEMBERSHIP '.
  (
  ACTIVATE THE "MPM_ID" NUMBER NOT NULL,
  ACTIVATE THE "MPM_ENG_ID" NUMBER NOT NULL,
  ACTIVATE THE "PHASE_NUMBER" NUMBER (2.0) NOT NULL,
  "DATE_STARTED" DATE NOT NULL ACTIVATE.
  DATE OF THE "DATE_FINISHED."
  'NOTES' VARCHAR2 (2000 BYTE),
  'DATE_CREATED' DATE NOT NULL ACTIVATE.
  ACTIVATE THE 'CREATED_BY' VARCHAR2 (20 BYTE) NOT NULL,
  NUMBER (2.0) 'ACTIVE' DEFAULT 1 ACTIVATE NOT NULL)
  
  So, basically, I want to fill the documents associated with a particular to a collection of APEX called PHASE_COLLECTION MPM_ENG_ID.
  Then when the user specify date_started and date_finished, it will update/insert the APEX collection first.
  Then the rank based on audit collection date
  http://www.Oracle-base.com/articles/Misc/overlapping-date-ranges.php
  then display the warning to ask the user to confirm message.
  
  But then I'm stuck at the step of updating COLLECTION of APEX.
  
  If anyone has any ideas on what is wrong, please help.
  
  Thanks in advance.

  Your syntx error line number should give you the trick - it is not a member of the update, rather the SQL - you are referring to apex_collection, not apex_collections view dictionary.

• Several elements of Application or Apex Collection?

  Hey everybody,
  
  I was wondering if I could get a glimpse on a novelty, I want to add my company to current APEX app.
  There is a set of 15-20 variables that will unfold in a database table that will determine some
  messages, images etc. which will appear on the application of the apex.
  
  I was wondering would it be better for the performance to create 20 items in application to hold these data, or a collection of Apex would be more appropriate.

  Codes says:
  I was wondering would it be better for the performance to create 20 items in application to hold these data, or a collection of Apex would be more appropriate.

  Whichever is easier for you to do work and performs very well (speed)

  If the elements are different, then the different elements may work better. If the elements are an extensible set of the same type of question as ID of employee or dates, then a collection might work better. Remember that if they are the same one editor could allow you to write less code for processing by a loop through the contents of the collection

• APEX 4.01 collections rendering problem

  I'm creating a collection using apex 4.01.

  I then added a region on the page.
  I've created a report in the region with a source of the sql query. I then placed the query in the source section.
  
  I created a load on before the header process which loads the EMP table collection.
  
  When I run instead of getting my output display as intended in the collection, it displays the data in the html tags. Its as if the HTML is not be stripped.
  I see where in the attributes report there is an option to strip HTML. I set to Yes. Its in the section layout and pagination of the attributes of the rpt.
  
  Here is an example of what the report is rendered:

  We use the care Assistant apex, now during the Validation process, we want to perform validation custom, is there a way that we can access the data? Please suggest?

  Hi all

  In the upload form, we have 4 Pages / screen, each screen has an associated collection of Apex.

  Below the Apex Collection are associated with Pages

  "SPREADSHEET_CONTENT" - page 1

  What interested me was in the PARSE_COL_HEAD that lists the columns that are not mapped on the 2nd Page, (data map).

  So now that we know the collection of the Apex, I will ask the Collection:

  Select count (c002) in the CNT from apex_collections where 'PARSE_COL_HEAD' and C002 = collection_name = "DO_NOT_LOAD";
