• Procedure that injects another procedure

  Hello everyone,
  
  I need to create a procedure that removes another procedure as follows:
  
  create or replace procedure drop_any_proc (proc_name varchar2) is
  drop procedure proc_name;
  end;
  
  Please let me know.

  In essence:

  create or replace procedure drop_any_proc (proc_name varchar2) is
  begin

  But I would add even more around it... of error management and safety nets and wonder why I want such a procedure :)

• How to create a dynamic RTF report that creates dynamic columns based on the selection of dynamic columns in a table?

  Hi all

  Suppose I have table, whose structure changes frequently on a daily basis.

  For example. / / desc my_table gives you after the name of the column the day 1

  SQL > my_table DESC;

  Output

  Name

  Age

  Phone

  
  

  Day 2, two other columns are added, viz, address and salary.

  SQL > my_table DESC;

  Output

  Name

  Age

  Phone

  Address

  Salary

  
  

  Now, I want to create a Dynnamic RTF report which made extracting data from all columns from my_table daily. For this, I have defined a simultaneous program with XML output type and include in annex a data/definition of data model that takes XML as input and gives the final result of the conc program in EXCEL layout. I am able to do that for a constant number of columns, but don't know how to do it when the number of columns to display dynamically changes.

  For 1 day my XML file should be like this.

  <?xml version="1.0" encoding="UTF-8"?>
  <dataTemplate name="XYZ" description="iExpenses Report" Version="1.0">
  <dataQuery>
  <sqlStatement name="Q2">
  <![CDATA[
  SELECT Name
  ,Age
  ,Phone
  FROM my_table
  ]]>
  </sqlStatement>
  </dataQuery>
  <dataStructure>
  <group name="G_my_table" source="Q2">
    <element name="Name" value="Name" />
    <element name="Age" value="Age" />
    <element name="Phone" value="Phone" />
  </group>
  </dataStructure>
  </dataTemplate>
  
  

  And my day 1, EXCEL output RTF model should be like this.
  Name age phone

  Swapnill 23 12345

  For 2 days my XML file should be like this. With 2 new columns selected in the SELECT clause.

  <?xml version="1.0" encoding="UTF-8"?>
  <dataTemplate name="XYZ" description="iExpenses Report" Version="1.0">
  <dataQuery>
  <sqlStatement name="Q2">
  <![CDATA[
  SELECT Name
  ,Age
  ,Phone
  ,Address
  ,Salary
  FROM my_table
  ]]>
  </sqlStatement>
  </dataQuery>
  <dataStructure>
  <group name="G_my_table" source="Q2">
    <element name="Name" value="Name" />
    <element name="Age" value="Age" />
    <element name="Phone" value="Phone" />
    <element name="Address" value="Address" />
    <element name="Salary" value="Salary" />
  </group>
  </dataStructure>
  </dataTemplate>
  
  

  And my day 2, exit EXCEL model RTF should be like this.
  Name address telephone pay

  23 12345 Madrid 100000 Swapnill

  Now, I don't know below things.

  • Make the dynamic XML as we did in the day 1 there are 3 columns in the SELECT statement and the day 2, 5 columns. I want to create a dynamic XML which must not be changed if the new columns are added into my_table. I don't know how to create this query and also create their corresponding items below.
  • Make the RTF model dyanamic as day 1 there are 3 exit EXCEL columns and the day 2, 5 columns. I want to create a dynamic RTF model that would display all the columns selected in XML dynamic. I don't know how the RTF will create new XML tags and how it will know where to place them in the report. Means, I can create model RTF day 1, by loading the XML data for 3 columns and place 3 tags XML in the model. But how he will create and place the tags for the new columns the day 2?

  Hope so, you got my requirement, it's difficult. Please let me know how I can implement the necessary solution using the RTF dynamically without any manual intervention.

  Kind regards

  Hi guys,.

  I was able to solve above the requirement.

  I created a procedure that would create & update (attached to the data definition) XML file dynamically for each race. This dynamic XML contains the SQL statement for the data query that is built dynamically. I am updating this XML file using XDOLoader utility to the definition of data. Then run my program customized to generate the excel output.

  Exit excel retrieves correct number of columns dynamically (3 on Day1 and Day2 5), with corresponding data records.

  Kind regards

  I created two columns using an alter table statement that is Approx_car_year, Approx_car_age.

  I do not require the Approx_car_year column so if there is a way to perform the calculation without it would be great.
  
  Thank you much in advance.

  Please note that I am assuming that you also want to update approx_car_year table column. If this column is not present in the table or you don't want to update, then you can remove it from the update statement mentioned above.

  I hope this helps.

  Hello
  In case the solution given by Rod does not work, perhaps because of sorting you can try this:

  1. create a calculated item, say called BASEVALUE and enter 1 for the calculation

  2. create this second calculation:

  * Sum (BASEVALUE) (ORDER BY sorting your items LINES UNBOUNDED PRECEDING) + variable departure*, so if your sort were growing sorted POINTS and MYDATE down with a 500 starting point it would be as follows:

  SUM (BASEVALUE) OVER (ORDER BY ASC, DESC MYDATE ROWS UNBOUNDED PRECEDING ELEMENTS) + 500

  3. remove the spreadsheet BASEVALUE so that it does not appear

• I've created a form that uses the value field text to fill the text of another field.  Does not take into account changes

  I've created a form that uses the value field text to fill the text of another field.  However, if I need to change the text, the second field does not update this change.  Instead of reset the form each time, is the Javascript code to update the fields if they have been modified?

  For example I Text1 and Text2.

  When I type in Hello in Text1 I see Hello in Text2.

  Later, if I decide to change to Goodbye Text1, Text2 remains Hello.

  The shape of the hoe can recognize this change?

  Thank you

  Edit: I think I have misunderstood the situation.

  If you want to both fields have the same value, just to give them the same name.

• Creating a button that highlights himself and another object

  Hi all

  I have a specific function, I am applying for my InDesign document for export to interactive PDF and SWF/html format.
  The function that I am creating is:
  I have a picture of a typical WYSIWYG toolbar. I created highlight buttons that sit on top of each icon in the image. When the reader hovers over this image of an icon (with the cursor) I want it highlight and also a piece of text lower on the page to highlight as well (which is a definition and an explanation of the icon). So I want the reversal of my first button action to also trigger another action, which is to highlight a piece of text somewhere else on the page. I managed to get so I put the cursor on the first button (icon image), it highlights, and the text below the page. But this isn't quite what I want. I want the text already exists, then highlight. Basically I want the two buttons to be connected. So that whenever I have fly over a part of the image of a created button, it will highlight, and a piece of exploratory text highlight simultaneously elsewhere on the page. A bit like an infographic. It is surely possible?

  Thanks in advance for your help.

  Generally, the animations as this is to export a SWF file are better be done in Adobe Flash.

  In Indesign that kind of market, too. Only for export as SWF, you can assign to the action "go to the State." For a text block, you can assign different status, where the 1st State would be 'normal' and the 2nd status would be "highlighted". Highlighted applies to the object "text frame", so that you can assign a contour or background. Better than nothing.

  Example: Dropbox - test_highlight.indd

• Is it possible to create interactive drop-down lists that reference the tables on pages separate from the PDF?

  I'm looking to create a user to input PDF in the drop-down lists are used to search for tables, however, I'm not very familiar with the options that are available or if this is even possible?  Also, is it possible to write a substantive code that could read the text of the user entered to perform a search or even solve an equation? Can someone let me know if these elements are possible and/or let me know what adobe program may be required to accomplish these tasks? Thank you!

  PDF documents have no concept of "tables" as MS Word or MS Excel has. There is content that looks like a table.

  Acrobat JavaScript knows tables and form fields. So we could have a table in JavaScript and complete a series of fields that looks like a table. You can use JavaScript to find the table.

  JavaScript in Acrobat can accept user entries in the fields and pop-up windows.

  It is possible to solve theoretical equations the user if the good rating or coding is used.

  D.P. Story is an evangelist generated LaTex PDF to create PDFS with mathematical symbols, and he also created the AcroTex product that allows to create educational tools that includes mathematics calculation self placement tests.

• I am trying to create a function that would be on the table type returns.

  Gurus,
  
  I am trying to create a function that returns a table nested with 3
  columns in a table as a guy.
  
  my query is like
  
  Select col1, col2, col3 from table_1;
  
  I am a bit newbie in Oracle and have never used collections.
  Can you please guide?

  Then you should start with the documentation
  http://docs.Oracle.com/CD/B28359_01/AppDev.111/b28370/TOC.htm

  Chapter 5 is all about collections using PL/SQL and examples

  This isn't enough of a description to know what you're trying to do, or how you plan to use the service. The query you provided is completely irrelevant to the question you are asking.

  You ask about functions in pipeline? Here is an example of this

  -- type to match emp record
  create or replace type emp_scalar_type as object
    (EMPNO NUMBER(4) ,
     ENAME VARCHAR2(10),
     JOB VARCHAR2(9),
     MGR NUMBER(4),
     HIREDATE DATE,
     SAL NUMBER(7, 2),
     COMM NUMBER(7, 2),
     DEPTNO NUMBER(2)
    )
    /
  
  -- table of emp records
  create or replace type emp_table_type as table of emp_scalar_type
    /
  
  -- pipelined function 
  
  create or replace function get_emp( p_deptno in number )
    return emp_table_type
    PIPELINED
    as
     TYPE EmpCurTyp IS REF CURSOR RETURN emp%ROWTYPE;
      emp_cv EmpCurTyp;
      l_rec  emp%rowtype;
    begin
      open emp_cv for select * from emp where deptno = p_deptno;
      loop
        fetch emp_cv into l_rec;
        exit when (emp_cv%notfound);
        pipe row( emp_scalar_type( l_rec.empno, LOWER(l_rec.ename),
            l_rec.job, l_rec.mgr, l_rec.hiredate, l_rec.sal, l_rec.comm, l_rec.deptno ) );
      end loop;
      return;
    end;
    /
  
  select * from table(get_emp(20))
