  If you want to set the element from the procedure directly, you can use the APEX_UTIL. SET_SESSION_STATE function (a session valid apex)

  You could call it after authentication or Application process that runs when a new session is created

• How to pass values from one form to the other setting

  Hello
  
  I have created two forms Form_A and Form_A. Form_B, having a button "submit" and called the new form of B.

  In FormA, just before calling FormB declare and initialize a global variable

  :GLOBAL.PASS_BACK := ''; -- declaration and initialization

  You can set parameters of Pagecontext and transmit values through them. These values can be passed between pages, even if the AMs are different.

  Try:
  pageContext.putParameter ("Parameter1", value1);
  pagecontext.setForwardURL (second page)

• Return multiple values from a table

  Hi there I'm working on a bit of sql that returns values when they exist in a table.
  The code I have returns the correct value when there is an entry in the tbl_studentmodules table, as soon as there is more than one entry in this table it does display no line at all: (.)
  
  Can someone tell how to return multiple values?
  
  

               select modulename from tbl_modulefeedback
  where 1 = (select count(*) from tbl_studentmodules
         where upper(:APP_USER) = upper(student_id))
  and 1 = (select count(*) from tbl_modulefeedback, tbl_studentmodules
        where tbl_modulefeedback.modulecode = tbl_studentmodules.modulecode)

  Thanks in advance!
  
  Ashleigh

  Try this:

  select modulename
  from tbl_modulefeedback
  where 1 <= (select count(*) from tbl_studentmodules
         where upper(:APP_USER) = upper(student_id))
  and 1 <= (select count(*) from tbl_modulefeedback, tbl_studentmodules
        where tbl_modulefeedback.modulecode = tbl_studentmodules.modulecode)

• Return multiple values from a function in a SELECT statement

  I hope I've provided enough information here. If not, let me know what I'm missing.
  
  I create a view that will combine the information from several tables. Most are pretty simple, but there are a couple of columns in the view that I need to get by running a function within a package. Even if this is quite simple (I have a function named action_date in a package called rp, for example, that I can use to return the date that I need through SOME rp.action_date (sequence_number).
  
  Here is the question: I really need to return several bits of information of the same record (not only action_date, but also action_office, action_value, etc.)-a join of the tables will work not here, as I will explain below. I can, of course, perform a function separate for each statement, but this is obviously inefficient. Within the select statement of the view, however, I don't know how each of the values that I need to get back.
  
  For example, right now, I have:
  
  Table 1:
  sequence_number NUMBER (10),
  name varchar (30),
  ...
  
  Table2:
  Table1_seq NUMBER (10),
  action_seq NUMBER (10),
  action_date DATE,
  action_office VARCHAR (3),
  action_value VARCHAR (60),
  ...
  
  I can't just simply join Table1 and Table2 because I have to perform processing in order to determine the rows returned matching, I really need to select. If the package opens a cursor and treats each line until it finds the one I need.
  
  The following works but is ineffective since all calls to the package returns the columns of the same record. I don't know how to put all the values that I need in the SELECT statement.
  CREATE VIEW all_this_stuff AS
  SELECT sequence_number, name,
  RP.action_date (sequence_number) action_date,
  RP.action_office (sequence_number) action_office,
  RP.action_value (sequence_number) action_value
  FROM table1
  
  Is there a way to return multiple values in my SELECT statement or I'm going about this all wrong?
  
  Any suggestions?
  
  Thank you very much!

  Hello

  What you want is a Query of Top - N , what you can do using the ROW_NUMBER analytic function in a subquery, like this:

  WITH     got_rnum     AS
  (
       SELECT     action_seq, action_dt, action_office, action_type, action_value
       ,     ROW_NUMBER () OVER ( ORDER BY  action_date
                                 ,            action_seq
                           ,            action_serial
                         ) AS rnum
       FROM     table2
       WHERE     action_code     = 'AB'
       AND     action_office     LIKE 'E'     -- Is this right?
  )
  SELECT     action_seq, action_dt, action_office, action_type, action_value
  FROM     got_rnum
  WHERE     rnum     = 1
  ;
  

  As written, this returns a single line (at most).
  I suspect you'll actually get a rank for each group , where a group is defined by a value in a table in which you join.
  In this case, add a PARTITION BY clause to the ROW_NUMBER function.
  If post you a small example of data (CREATE TABLE and INSERT statements), I could show you exactly how.
  As I don't have your tables, I'll show you the use of the tables in the scott schema.
  This is a view containing data in the scott.dept table and also to scott.emp, but only for the highest employee in each Department (in other words, the employee whose oldest hire date). If there be a tie for the first hire date, while the candidate with the lowest empno is selected.

  CREATE OR REPLACE VIEW     senior_emp
  AS
  WITH     got_rnum     AS
  (
       SELECT     d.deptno
       ,     d.dname
       ,     e.empno
       ,     e.ename
       ,     e.hiredate
       ,     ROW_NUMBER () OVER ( PARTITION BY  d.deptno
                                 ORDER BY          e.hiredate
                           ,                e.empno
                         ) AS rnum
       FROM     scott.dept     d
       JOIN     scott.emp     e     ON     d.deptno     = e.deptno
  )
  SELECT     deptno
  ,     dname
  ,     empno
  ,     ename
  ,     hiredate
  FROM     got_rnum
  WHERE     rnum     = 1
  ;
  
  SELECT     *
  FROM     senior_emp
  ;
  

  Output:

  .    DEPTNO DNAME               EMPNO ENAME      HIREDATE

  Moreover, one of the conditions to the query you posted has been

  action_office     LIKE 'E'
  

  which equals

  action_office     = 'E'
  

  (AS is always equivalent to = if the string that follows AS does not contain the winning cards.)
  Did you mean say that or did you mean something like this:

  action_office     LIKE 'E%'
  

  Instead?

• Copy the default value from another field in the same page

  Hello

  I need to pass a value from one page to another page and I want to use this key as DEFAULT VALUE for a field.

  If I create a form tabular all it's ok, but if I create a normal page. I am not able to do that.

  1. 1. I call the page and I pass the value. I also have a FIELD of VIEW and I can see the correct value.
  2. 2. I create a field with attributes of this:
     1. a. source > Source = database column type
     2. b. sources > Source value or expression = FK_ID_DA (the column name)
     3. c. default > default = P27_PK_ID_DA (the field that contains the value)
  3. 3. on the screen, I see P27_PK_ID_DA and not the value

  Where is the error?

  Thank you very much

  TexasApexDeveloper wrote:

  You missed one: before the variable, without it, the default value is the string...

  Not sure that you can READ the other pages... Such that if you are on Page 27 and have a field that you want to use on page 30, page 27 is presented and its items in session state, you can 'see' on page 30.

  So, if you set the default value: P27_PK_ID_DA, then you should get by default, you are looking for...

  Only if the default value Type is set on the PL/SQL Expression. If the literal value "P27_PK_ID_DA" is seen then the Type of default value should currently be set static text with Substitutions of State of Session, in which case the value of session state must be referenced using the syntax of substitution string:

  &P27_PK_ID_DA.

• APEX - passing values from one page to the other

  Hello
  
  I created a new page with a report. I put one of the columns as a link that opens another page. This page should contain other details of the particular line.
  
  For example:
  There is a page with a list of employee names and the number of employees in both columns. When I click on the name of employee, he must open another page with additional details of the employee in particular (such as date of birth, e-mail etc.).
  
  What I'm trying at the moment is to create another page with a report inside. How do I pass the name of the employee as a parameter to this second page? And how do I do the query in the second page accept this setting?
  
  Is there a better way to do this?
  
  Kind regards
  Santhosh Jose

  Hello

  on your detail page (2nd report) create a hidden page element called P2_EMPID
  Now change the query on this page to use this page element in the where clause (such as a variable binding).
  for example:

  Select * from EMP
  where empid =: P2_EMPID

  On your first page, you need to set a link to the column for the chosen, employed at the point P2_EMP on the second page. This can easily be done via a column binding in the report on the first page (have it redirect to a page in the apex and set the page to the second page of the report, and also set the P2_EMPID value to the value of #EMPID #, correcting the names of these variables can be chosen in the selection lists when you set the link in the column).

• Oracle form functions and procedures in the APEX, how?

  I'm working to recreate in the APEX, already existing read only forms in Oracle Forms. Report features interactive APEX among other things, in fact worth as well as to target a different audience than utilizies versions of Oracle Form. Versions of Oracle Forms use a lot of pre and post query triggers, PLSQL functions.
  
  In Oracle Forms that places, these functions can be found in the "Units of program" section of the form. A feature typical of this kind, based on a particular Mission ID route, collecting names of regular passengers, is shaped with a comma and a space after each of them, in a single string that is returned and displayed the list of passengers of a line.
  
  I have all of this written code so I can move most of the main request of the Oracle form in an interactive report. These functions and triggers called in the form of the "Units of program" section of the Oracle form rather than stored in the database schema in a package, where they would go inside the APEX? Can I create a 'shortcut' in the APEX and call it from the interactive report "Source Région"? I can create the PLSQL function at the level of the region of the interactive report or page level? Or, my best bet creates a package that is stored in the database, all these functions and/or proecedures I might need the original form of Oracle?
  
  Some advice would be greatly appreciated.

  I don't think I've been pretty clear in the description of the specific thing I want to do, simply, it does not reach the level of forms of conversion of the APEX. It is basically a problem of PLSQL function.

  I have an interactive report which is currently 90 percent of what I want however, each line, which represents a Mission may have several feet. Each arm has two places or ICAO codes attached to it. Based on the number of Mission, I want to loop through the array of leg, collect all the codes of ICAO for this Mission, put them together in 1 variable separated by a coma and add this variable to display the columns in this interactive report as the last column.

  In Oracle Forms, I have a function registered in the database, which is called in the main query. Maybe I ask a question that does not need to be asked, but anyway my question is can I put this function currently in the database somewhere within the interactive report and somehow reference it via Http, or should I just stick with set of functions and procedures in the packages stored in the database and called the conventional way?

  You could switch the function to the database and call it from the report query, but it sounds as if it were superfluous. In the report query using any form of Re: 4. How can I convert rows to columns? is appropriate for your version of the (unspecified) database.

  When you have a problem, you will get an answer faster, more efficient including information as much information as possible from the outset. This should include:

• Full version of APEX
  
• Complete operating system DB, version, edition, host
  
• Architecture of Web server (EPG, SST or APEX listener/host operating system)
  
• Browser (s) and version (s) used
  
• Theme
  
• Model (s)


• Region/section type (s) (particularly as to distinguish if a 'report' is a standard report, an interactive report, or indeed a 'update report' (i.e. a tabular presentation))

  With APEX, we also had the chance to have a great resource in apex.oracle.com where we can reproduce and share problems. Reproduce things is the best way to solve most of the questions, particularly those relating to the layout and Visual formatting. If you expect a detailed response it is appropriate that you take on an important part of the effort by getting as much as possible with an example of the problem on apex.oracle.com before asking for help on specific issues, then we can see firsthand.

• How the procedure returns a value as a result of the query

  Dear Sir

  I have a requirement that I want to get a tabular output, we will for example

  Create procedure my_test_ret_chr is

  Table type is table of the varchar2 (30) index directory.

  a table;

  procedure p (table array_in)

  is

  Start

  I'm looping 1.array_in.count

  dbms_output.put_line (array_in (i));

  end loop;

  end;

  Start

  a.1: = 'Apple ';

  (2): = "banana";

  3 a: = "Pear";

  p a;

  end;

  Select double my_test_ret_chr

  When I run this query, it shows the result in a table records like select empno emp;

  Then use function pipeline as already say:

  SQL> CREATE OR REPLACE PACKAGE my_pkg IS
  2  TYPE t_col IS RECORD(
  3  i NUMBER,
  4  n VARCHAR2(30));
  5  TYPE t_nested_table IS TABLE OF t_col;
