View contents of record variable at debug time

My PL/SQL package I'm debugging contains some RECORD type definitions. How can I see the contents of variables fo these types at debug time.
The data tab shows the variable with an empty value and a type of 'OPAQUE'. As things currently stand for me I am simply unable to debug this code if I can;t see the contents of my variables.
What have I done wrong? Or is the tool currently not able to show me this information. If this is the case is there any sort of workaround.

Naveen,
I am able to find document_type_id with this
SELECT --document_extra_info_id
FROM hr_document_extra_info
where person_id=<>
But I am not sure how I need to see the document.
I dont know whether document exists or not?
My Questions are
1) Which path will documents store at server side?
2) I am able to create docs now and I am able to view the docs now. But I am not able to view the existing docs. I am not sure whether docs exist or not.
for this reason, I need to check whether docs exits in the path or not? Is it conversion issue or not? Please let me know.

Display for variable amount of time?

Any thoughts on how I might accomplish the following:
I need to be able to display a graphic (or video) for a variable amount of time in captivate. This will be for a quiz type slide. The user will only have a limited amount of time to view a graphic, and then must answer a question. The graphic will only be displayed for fractions of a second ie. 1/16 to a half second. The user must be able to adjust the time, so that they can go from slow transitions to faster transitions (for training purposes).
My initial thoughts were:
Is there a me
1) Collect and set a variable in Captivate for the time to wait (user selects at run time), pass that variables value to a flash object and play the content for the specified length of time on the Captivate slide.
or
2) Create a new question type widget and define the widget parameters (time to display, image file to use, etc..), but will I be able to change a parameter at run time to allow the user to define the length of time to display???
or
3) Create the whole quiz in Flash, then tackle transmiting the quiz score/interactions back to captivate? I don't have eLearning suite, so I dont have the question extras as well.
I would prefer to do as much in captivate for speed and I am most familiar with it. I would prefer to do as little in Flash as possible since I don't know it as well.
Suggestions???

Sorry I lost part of the post:
Is there a method in Captivate to wait a period of time, and if so just set a conditional loop to show an object, wait the time, and then hide? I am figuring that there is not, so my three other plans of attack...

Cannot view content grabber in Illustrator CC

Hi all,
I'm very new to Illustrator and finding the learning curve to be quite steep. Two questions - First, is there a kind of "getting started guide" with a brief explanation of the very basics and all features? The little random tutorials they show upon opening the program are helpful, but totally random and I can't find a list of contents even, to go through. I find I'm looking things up one thing at a time, issue by issue. That can't be the best way to learn the basics for a home user.. can it?
Major question right now as I'm using it.. I'm finding that I often cannot see the content grabber on images that I open (from iPhoto, for example) in Illustrator CC. I'd like to see that brown frame to quickly crop the image but the content grabber never shows up so I can't do that. The only "solution" I've seen is to go to View>Extras>View content grabber. But in this version, there is no "extras" in my view menu.
I feel like this is so incredibly basic but I'm learning as I go and totally lacking in resources here.
Thanks in advance.

How to Print the whole view content from a button on the View Layout

How to take print whole view content(lay out) in
webdynpro application.i.e whatever it may be tablecontent or label or inputfield .
Could you send the coded part briefly step by step from the beginning itself i.e
i put the button in the view lay out below the printed parts(label or inputfield) name like show preview .
Now my Question is what should i write in show preview function to take the print in label fields in the webdynpro view lay out
B'cos i am new to webdynpro.Help me
Thx in advance

Web Dynpro by default does not provide the option of printing the view content.
However still you have a round about way of doing it. Create the an html page similar to the Web Dynpro page. Store the code into a String variable.
String html="<html> ....<scripts>window.print()</scripts></html>";
bytes[] source=html.getBytes();
try{
byte[] b=new byte[1];
IWDCachedWebResource res=WDWebResource.getWebResource(b,WDWebResourceType.HTML);
String url=res.getURL();
}catch (WDURLException e) {
// TODO: handle exception
Now open the url in a new window and that would print the content of the html page.

Using numbers 2.3 how do i split windows to view more than 1 spreadsheet at a time?

using numbers 2.3 how do i split windows to view more than 1 spreadsheet at a time?

Hi seth,
Numbers vocabulary:
Spreadsheets (aka: Document)
contain one or more Sheets
on each of which may be placed one or more Tables
each of which contains one or more cells
each of which may contain either data or a formula.
Spreadsheets open in separate windows. Depending on the contents of each spreadsheet, and the scale at which you want to see it (and the size of your display), you can view more than one spreadsheet in the same manner as you can view more than one of any kind of document—open two documents in separate windows. Resize the windows to allow both to be viewed at the same time. Place and scale the individual documents to permit viewing the desired part of each
Sheets within the same document cannot be displayed simultaneously. You can make and open a copy of the document, then open and view both copies as described above, but this introduces new opportunities to edit the wrong copy. You could Copy a Table from one part of the document, open Preview and go File > New from Clipboard to create a PDF copy of that table (readable, but not editable), and view the spreadsheet and pdf documents as described above.
Tables can be rearranged, or have rows or columns (or both) hidden to permit simultaneous viewing of selected parts of both.
A Table can have Table > Freeze Header Rows and Table > Freeze Header Columns set to keep these rows/columns visible as the rest of the table is scrolled. Or can have a range of rows (or columns) hidden to allow viewing of rows (columns) adjacent to that range visible on the same screen.
Numbers does not support freezing of rows or columns other than Header rows and Header Columns.

"view content preview in thumbnails" option is not available in view settings for "finder" for one user

"view content preview in thumbnails" option is not available in view settings for "finder" for one user

I hope this discussion can be revived. I have the same problem. There seem to be quite a few Japanese sites that don't bother specifying their encoding. Perhaps they are older and from a time when it was not necessary to adhere to standards. Examples: http://www1.plala.or.jp/CUE/cave_yozawa.html, http://chigaku.web.fc2.com/saitama/sanchi/youzawa/youzawa.html. Happy to upload screenshots, but how?
Is there a way to tell Safari what encoding to use if the web page fails to do that?

I can't place the content of a variable in a TextField

Hi.
I have a TextField made at authoring time. I need to place
the content of a variable in a TextField.
The variable counts the clicks and i want to display the sum
in a TextField.
Here is the code I made:
var limit:Number=29;
var count:Number=0;
var current:Number=0;
_root.mask_mc.onPress = function() {
_root.bat_mc.gotoAndPlay(2);
if(count<limit) {
count++;
}else{
_root.nextFrame;
count=0;
_root.scor_txt.text = count;

yes, that's right, (this code look very similar to something
I wrote for someone the other day ;)
I would also not call to _root as it doen't look like it's
needed here, if this resides on the main timeline (it looks that
way from here :) (if not leave them in there, I just don't like
calls to _root much)
also you will need to use:
nextframe();
so it should look more like:

How to execute the content of varchar variable like a simple query

Hi everyone!
I did a PL/SQL region in apex, in this region I did the query which is storaged in a variable; it was did it concatenate several times,
in the procedure I have several sentences.
I thought that the command 'execute immediate' would get a good result but it do not print the result.
declare
variable varchar2(1000);
begin
--sentences
--execute inmmediate( variable );
--return variable
end;
I only want to how to execute the content of varchar variable.
For example, suppose that the result of this procedure is
'SELECT SYSDATE FROM DUAL'
How and what do I must do for this query execute like a normal query that is in apex?
I expect your prompt reply.
Thank you for your help.
Best regards

Let us say your table containing SQL is
t_sql_table
and has two columns
primary_key
and
sql_query.
You would need to do the following:
1. Create a Report of type "Function returning SQL Query"
2. Put the following there:
DECLARE
   v_query   VARCHAR2 (4000);
BEGIN
   SELECT sql_query
     INTO v_query
     FROM t_sql_table
    WHERE primary_key = 1;
   RETURN v_query;

Does a table/view still return records if the underlying VPD policy fails ?

Hi All,
I have one following question -
Does a table or view still return records if the underlying VPD policy fails?
I am adding one more thing here. Let us say security is being implemented using the application context and VPD.
What would happen when application context is not set ? Would the application apply any default privilege as VPD?
Thanks,
Ashi

If you are truly setting a VPD, you have to make sure that the context is set and the condition variable are passed through it. This is normally done through a logon trigger so again, generically , its not possible that it would not be set. I didn't get at all what ever you said in the last line? What is "default priv for VPD" ?

Create record variable that refers dynamic query assigned to a ref cursor?

Hi ,
Just explaining what I am trying to achieve:
1) i have a hr.departments table that was loaded in hr schema on 1st oct 2012 with 4 columns(department_id, department_name, manager_id, location_id)
2) now I have a new schema by my name 'rahul' and I have loaded departments table but now an additional column has come into picture,ie created_date, this table got loaded on 1st-Nov-2012
3) Now going forward my columns could be dropped from the departments table (it can be a case), for example might be my departments table in my schema 'rahul' one day could comprise of only 3 columns(department_id,department_name,manager_id)
4) Now in the next step, I have managed to extract common column names(in a single line where columns are delimited using a comma) from both the tables(hr.departments and rahul.departments) which are (department_id, department_name, manager_id, location_id) using all_tab_cols table and I have written a function for it which i will be pasting below.
5) now going forward, using the above column names line with column names delimited using comma, I have used a ref cursor and assigned a query to it using the line of columns that I have extracted from the above point
6) Now I want to create a record variable which refers to my ref cursor, something like we do when we create a record variable by reffering to an explicit cursor defination that we give in the declaration block.
PS:
1) I have been out of touch with plsql for a long time so I have lost a lot of mmeory regarding plsql.
2) basically I need to compare data in hr.departments table with rahul.departments table for only columns that are common to both the tables, rest new or discarded columns information will go in one of the log tables that I have created(this is done already)
Please help me, I did try searching on google for the same but it really confused me very badly, any kind of help is appreciated, please find my code below:

This thread is basically nothing more than a continuation of your original thread except now you are finally explaining what you are really trying to do.
Re: passing table name to a procedure and then need to open a cursor ..
In that original thread you said you found the solution

Well Mate thanks for your suggestion but I got it working through ref cusror, thanks for your time.

So I ask you to post your 'solution' and when you finally did it was clear that you hadn't solved anything at all. Your solution used a ref cursor all right but the code relied on a record ('record_employees') that was based on a table name ('employees') that was declared within the procedure. There isn't much point in passing in a table name if you have to hard-code the table name in the procedure.
create or replace procedure p_ref_cursor(fp_old_table in varchar2)
is
type ref_cursor is REF CURSOR;
v_ref_cursor ref_cursor;
record_employees hr.employees%ROWTYPE;
begin
open v_ref_cursor for 'select * from '||fp_old_table;
loop
fetch v_ref_cursor into record_employees;
exit when v_ref_cursor%NOTFOUND;
dbms_output.put_line(record_employees.employee_id);
end loop;
end;Then sb92075 ask you the question that illustrates what I just said

And you blew him off with this

Mate, departments never came in my context, in my prior message I explained what I was trying to achieve ... so I dont know what problem you are understanding reading my posts.

And now here you are asking how to get this to work for the departments table.
It is very difficult to help someone that won't tell us what it is they are really trying to do so we can try to suggest some better ways of doing it. Hopefully, in the future, you wil start by explaining your problems instead of focusing on the solution you think you should use.
Back to the issue -
The first thing you should do is finish defining the requirements. Assuming the above actually works to identify columns that have different data what are you going to do with that information?
1. Do you need to save that different data from TABLE1 somewhere?
2. If you don't save it how will anyone look at it to decide which table has the correct data?
3. If you do save it how will you save it 'generically' since other tables will have different columns and datatypes?
4. What about the data from the same record in TABLE2; do you need to save that data somewhere?
5. Will these two tables have primary keys? Are they on the same columns in each table? If not what if TABLE1 has one record but there are TWO records in TABLE2 that are identical. Is that a match? Or is that a problem because TABLE2 has an extra record even though the record is identical?
In short detecting the differences is just one small part of the entire problem. You also need to save those differences somewhere so someone can examine the data and decide what action to take. That is the more difficult part of trying to implement a 'generic' solution.
But now that we know what you are really trying to do take a read through this thread from 6 years ago. It has three different ways to pass a query to a procedure and get different output. You may want to save a copy of the thread since it has some very advanced techniques in it.
