Question about nested tables

Hallo everyone,
I have a problem with nested tables. I can create them and insert data with the sql command line. It is not possible in the browser.
But I cannot view the values - neither in the command line nor in the browser.
In the browser, oracle shows this error-message:
'ORA-01031 insufficient privileges' (I have admin rights!!)
Is it possible that Oracle Express Edition doesn't support all object-oriented features?
Thanks in advance

I downloaded the latest apex 3.0.1, but itshouldn't
be used with Oracle XE according to theinstallation
guide.Where did you read that? There's even a XE releated
install guide:
[url=http://www.oracle.com/technology/products/databas
e/application_express/html/3.0.1_and_xe.html]Oracle
Database XE and Application Express 3.0.1C.
when I downloaded apex, the documentation in the database requirement (2.1) says:
"Note:
Do not install this version of Oracle Application Express on Oracle Database Express Edition (Oracle Database XE)."
Maybe the documentation is not up to date, because I downloaded last week

Question about Update Tables

Hello Gurus,
I have a question about "update table" entries. I read somewhere that an entry in update table is done at the time of the OLTP transaction. Is this correct? If so, does this happen on a V1 update or V2 update? Please clarify. Similarly, an entry in the "extraction queue" (incase you are using "queued delta" will happen on V1 update. I just want to get a clarification on both these methods. Any help in this matter is highly appreciated.
Thanks,
Sreekanth

Hi
update tables are temporary table that are refreshed by v3 job.update table is like buffer, it gets filled after updation of application table and statistical table through v1 v2 update . we can bypass this process by delta methods.

About nested tables in oracle 8i

hello,
actually i am working with oracle 8.1.5 's nested tables
concept...
here is a description of my tables
create type parameterranges
parameter_name varchar2(20),
min_value number(10),
max_value number(10)
create type parameter_ran as table of parameterranges
create table material_details
mat_type varchar2(20),
parameter_ranges parameter_ran
okay...
now my doubt is how do i place constraints on the nested table fields i.e on min_value etc...(especially NOT NULL
constraint)
DOUBT NO 2
=============
I have a query to find out the mat_type,partno from material_details table Based on the parameter value and its min_value ,i.e based on some name value pairs which I am achieving as below .
select m.mat_type,m.partno
from material_details m,table(m.parameter_ranges) p
where p.parameter ='THICKNESS' and p.min_value = '1'
and m.mat_type='STEEL'
intersect
select m.mat_type, m.partno
from material_details m,table(m.parameter_ranges) p
where p.parameter ='STANDARD' and p.min_value = 'SAE1010'
and m.mat_type='STEEL';
Now I want this to be in a cursor..i.e I want to use the same set of rows returned by the above in another query involving another table .
That is using the multiple mat_type and partno returned from above I want to find out
Other fields (company,plant) from another table part_details which also has a nested table in it
How do I go about this???Actually I want to use these in a PLSQL procedure where we can have row by row control of the rows returned ,that is why I want a cursor.......
could u think about this too...and if possible mail me at my yahoo id ..
thanx once again
please reply to my id
[email protected]
thanx

I don't understand exactly your problem. Can you send me a mail which expresses your problem??

Using Multiple Subpaths - question about nested XML data

Hello.
I am in the process of getting my head around the nested XML data that is one layer deeper than I know how to handle - ultimately I would like to populate a Spry MenuBar from the static XML file.
Updates & revisions to the menu would be done by simply uploading a new XML file to the server whenever something needs changed.
The problem I am having is in regard to more than one subpath.
I can successfully get the "Menuheading" and the "items" to show but the "subitems" that should attach to the "items" are nowhere to be found. Once this is figured out, I will begin building my menu.
I'm not getting an XML error when testing in Safari (Mac OS 10.5.8)
I thing my problem lies here in the head section of the page - obviously somewhere in the subPaths area:
<script type="text/javascript">var dsItems1 = new Spry.Data.XMLDataSet("MenuXML.xml", "/menu/menuitem", { subPaths: [ "items/item", "subitem" ] });
and here in the body section at subitem:
<tr spry:repeat="dsItems1">
<td>{@id}</td>
            <td>{menuheading}</td>
            <td>{items/item}</td>
            <td>{subitem}</td>
        </tr>
==================================================
The end result I would like rendered in the menu is:
==================================================
Menuheading
---- Item (hyperlink)
---- Item (hyperlink)
---- Item (hyperlink)
---- Item
       ------- sub submenu item (hyperlink)
Menuheading
---- Item
       ------- sub submenu item (hyperlink)
       ------- sub submenu item (hyperlink)
       ------- sub submenu item (hyperlink)
---- Item (hyperlink)
---- Item (hyperlink)
---- Item (hyperlink)
...and so on.
I have attached both files in their entirety at the bottom of the post in hopes someone can help.

Should I be doing something with the Spry.Data.NestedXMLDataSet instead?
If so, how do I implement that?
many thanks in advance

Yes, you should be using the nested dataset instead.

SSMA (Access - SQL 2012) newbie question about new tables

I have successfully run SSMA and moved the back end tables of an Access project to SQL Express 2012.
Some questions:
- if I add a new table to the SQL backend, how do I get it to appear in the Access project?
- if I want to move the whole thing to another computer, how do I go about it?
- do I always have to have the SSMA app installed?
- I can't see an ODBC datasource on the machine
Thanks for some help
CarolChi

Thanks, I was not clear in my questions:
1. Given that from now on the tables should all be in SQL, I think it would be better to create new tables in SQL them there rather than create them in Access and have to keep moving them to SQL with SSMA. So if I create a new table in SQL how can I
see it in Access? Or can I easily create a linked table in Access?
The table created by SSMA have this property:
If I create a new table in SQL and link it I get a more classic ODBC connection:
2. I am happy with SQL backup/restore, attach/detach. But how does Access know where the SQL Database has gone?
3. I thought the migration was a one time task, but from what you say it is an ongoing "linking" app. So I would be better to export my tables and re-link them to get something that can be moved to another network or computer?
4. The SSMA looks very much like an ODBC connection.
This is a new project so I will have to make lots of new tables and also move the whole thing around to different computers, on different networks.

Question about multiple tables and formulas in numbers

I was wondering about having a formula that effects one table based on data in the other table. I have a spreedsheet that i created for work. In column A is a list of addresses. In column B-ZZ is a list of "billing codes" the get applied to the service work done for that address.Its kind of difficult to look at this large spreadsheet on my iphone and edit it on the go. Is there a way to, Have another column, possibly on sheet 2 or something, where i type in these "billing codes" and they would fill an x or some other character in cell that corrisponds with that billing code on that address line? So to be as plain as possible, I want to enter data in one cell (another sheet if possible) and have it "mark" another cell in response to the specific data on that "entry cell." Im thinking this way because instead of scrolling back and fourth on the sheet on my iphone, to "mark" the boxes, i could just navigate to sheet 2 enter the data, or "billing codes" and they would "X" the cell that would match up with the code column and address row. each address row would have a seperate "entry field" in sheet 2, to make the formula easier. thanks for any help

Tom,
That's a lot of columns for jsut a table of marks that reflect an input. Sure, you could have each cell in that giant table check to see if some corresponding cell contains certain text, but that document is going to be slower than you might be able to tolerate.

Question about selection table analysis

Dear All,
My last post was closed by the moderator so I would like to ask a different question. Please apologize if my question is trivial.
1. There is a selection table seltab with one fields of type I, with the following contents:
I     GT     3     0
I     NE     8     0
The literature eg. ABAP Objects says that the control statement like IF or CASE can be used with logical expression IN.
Now I am checking if the variable test fulfills the conditions defined by the selection table.
DO 10 TIMES.
IF test IN seltab.
    write test.
ENDIF
test = test + 1.
ENDDO.
As a result I get a full list of values.
1 2 3 4 5 6 7 8 9 10
2. Now, if the table contains
I     GT     3     0
I get
4 5 6 7 8 10 as expected
3. If the table seltab contains
I     NE     3     0
the result also seems to be ok
1 2 4 5 6 7 8 9 10
The final question is. Is it true that the logical expression IN cannot be used with IF for more complex data comparisions?
Thanks,
Grzegorz

Well, the contents
I GT 3 0
I NE 8 0
I read as:
the variable fulfills the condition if is greater than 3 and not equal 8
test > 3 and
test <> 8
which should give the result from the example above a list
4 5 6 7 9 10
What is wrong with my analysis?
Regards,
Grzegorz

Question about GLPCA table

hi gurus,
i need to find a relation between profit center and G/L account to do same reporting on charges by profit centers.
in table GLPCA i have the fields i need, but i have a question: are all the charges traced in this table (GLPCA) ? in other words are all the vendors invoices present in this table.
Thank you.

Only for those entries in which profit center is assigned.
Eg :Say expenses or revenue for which profit center is assigned directly. only the expenses line item(i.e Dr) or revenue line item (i.e CR) alone will be there in GLPCA.
But in BSEG you can find both the entries(Dr & Cr) for the same doc, which you cant find in GLPCA.
Hope you understood.

More syntax questions about nested symbols

I have a symbol timeline that does everything I need it to do except to access a function within the stage symbol. I would have thought that calling the function in the stage symbol from a nested symbol (which is loaded dynamically, if that makes any difference) would be something along the lines of:
sym.getComposition().getStage().gotoNextSlide("slide5");
but no luck. I can alert the stage itself as [Object Object], which brings up another question. Is there an always-available property of objects that one can alert or trace to make sure the correct object is being targeted? I've had no luck with the symbol's id, name, or symbolName.

Sure. You've seen one form of the project I'm working on, though I'm at the next speedbump. Here's an excerpt of the involved parts.
I have the stage symbol and within that symbol, I have a function:
function gotoSlide(slideName){
          fadeTo(slideName);
function fadeTo(slideName){
     /// this all works fine, when called from the main timeline
In the composition, I'm loading slides from the library and on the timeline of one of those slides is the following.
navHidden = true;
var trueButton = sym.getSymbol("answers").$("true");
trueButton.bind('click',goNext);
function goNext(){
          sym.getComposition().getStage().gotoSlide("slide_05");
I know there are other syntaxes I could use but refactoring is in the future. The console log I get is:
Object [object Object] has no method 'gotoSlide'
It's slide 5 in these:

Question about temporary tables and imports.

Hello everybody.
Interesting one this. We have an application that uses global temporary tables. We refresh live to test using import of the application schema. I noticed when doing this yesterday that the temporary tables were being recreated in test as perminant rather than temporary.
Is there a reason for this? Has anyone come across this before? Is there a way around it (apart from manual checking)?
Many thanks
Rup

I believe exp/Imp will export and import it is Temporary table. I have just done a simple test to check and it works fine;

Question about multiple table JOIN syntax

Good morning,
I'm trying to join three tables and getting an error. Here is the query:
with
p (messageid, parentmessageid, subject) as
    select 2001, null, 'xyz'    from dual union all
    select 2002, 2001, 'ngh'    from dual union all
    select 2003, 2001, 'nghj'   from dual union all
    select 2004, 2001, 'pppp'   from dual union all
    select 2005, null, 'hhhhh' from dual union all
    select 2006, 2005, 'hhhhj' from dual
m (thread, messageid) as
    select 1004, 2001           from dual union all
    select 1005, 2006           from dual
select p2.messageid, p2.parentmessageid, p2.subject
from (p p2 left outer join m m2
                          on (p2.parentmessageid = m2.messageid))
       join m m3
         on m3.messageid = p2.messageid
;                which gives an "ORA-00918: column ambiguously defined.
I can't figure out why it gives that error. I fail to see the ambiguity.
Thank you for helping,
John.
P.S: In case someone wants to get a good laugh, here is a "solution" that does not have any ambiguity:
with
parentchild (messageid, parentmessageid, subject) as
    select 2001, null, 'xyz'    from dual union all
    select 2002, 2001, 'ngh'    from dual union all
    select 2003, 2001, 'nghj'   from dual union all
    select 2004, 2001, 'pppp'   from dual union all
    select 2005, null, 'hhhhh' from dual union all
    select 2006, 2005, 'hhhhj' from dual
messagethread (thread, messageid) as
    select 1004, 2001           from dual union all
    select 1005, 2006           from dual
j1 as
   select p.messageid, p.parentmessageid, p.subject, m.thread
     from parentchild                     p
          left outer join messagethread   m
                       on p.parentmessageid = m.messageid
j2 as
   select j1.messageid, j1.parentmessageid, j1.subject, j1.thread, m.thread t2
     from j1 left join messagethread m
       on j1.messageid = m.messageid
select j2.messageid, j2.parentmessageid, j2.subject, nvl(j2.thread, t2)
from j2
order by messageid

Hi Sven,

Is there a "hint" that could be used to test that hypothesis ?
John.I tried NO_QUERY_TRANSFORMATION and MATERIALIZE but the error still was there. So it might not be a problem of rewriting the query.
However I checked the explain plan for a similiar query which is working.

Question about dual table

Hi,
Can anyone clarify me this
Can I insert rows into dual table (being a programmer) ?? Using oracle 9i ... If no, can DBA do that ??? Say suppose, I have inserted 100 records in the dual table .. In any way, my applications are going to get hampered after inserting the records in the dual table
Regards

Or perhaps this:
SQL> SELECT * FROM
2 ( select rownum from dual connect by rownum <= 10 );
    ROWNUM
         1
         2
         3
         4
         5
         6
         7
         8
         9
        10
10 rows selected.In 9i at least you most certainly can insert into sys.dual, which is a regular table in the SYS schema, although you deserve all you get if you do so:

Question about af:table

Hi all, can you show me the way to turn off the "show all" option in af:table (when we use paging)? Thanks a lot!
Harry.

hi Harry
I'm not sure what your question is, but the af:table component in the SRList.jspx page of the SRDemoSample application uses "paging".
<af:table value="#{bindings.findServiceRequests1.collectionModel}"
         binding="#{backing_SRList.srTable}" var="row"
         rows="#{bindings.findServiceRequests1.rangeSize}"
         first="#{bindings.findServiceRequests1.rangeStart}"
         emptyText="#{bindings.findServiceRequests1.viewable ? 'No rows yet.' : 'Access Denied.'}"
         selectionState="#{bindings.findServiceRequests1.collectionModel.selectedRow}"
         selectionListener="#{bindings.findServiceRequests1.collectionModel.makeCurrent}">

</af:table>(tip : You can use "Your Control Panel" to make your name visible in forum posts.)

Simple beginner question about default tables (LOGMNR, etc.)

Hi all, I just installed SQL Developer and the Express server. I have worked with other SQL databases and with remote Oracle databases. But never been a DBA for an Oracle DB. I tried searching on LOGMNR and AQ$_, but couldn't find anything, hence this question.
If there is some online documentation that covers these particular tables and my question, then a pointer to that would be appreciated.
Anyway, I created a connection per the instructions and it seemed to work. But when I look at tables listview, I see a whole slew of tables. I assume these are all housekeeping/meta data tables (eg. information_schema in MySQL). Is this correct?
Also, short of manually creating a filter for each of the file types ("%$%"help", "LOGMNR%", "SQLPLUS%", etc.), is there an easy way to ignore these tables and just see the tables I want to create for testing purposes?
And I am curios why these all show up by default. Could it be that I am expecting something because of experience with other databases and am actually doing things the "wrong" way? Or is this just because I am using the Express Server? Or is there another (very good) reason for these tables to exist?
Thanks,
justme

The complete oracle documentation is at http://tahiti.oracle.com. There is a lot of it, but Log Miner and Advanced Queuing have their own manuals. You should also consider starting with the Concepts Manual followed by one of the "2-day" tutorials such as "2-Day DBA"
What user are you connecting as? It sounds as if you are connecting as SYS or SYSTEM if you can see the dictionary tables.
You should create a separate user to connect as.
(create user myuser identified by mypassword;
grant connect,resource to myuser;)

A question about sorting tables.

Hello All!
Just a quick question: performance wise, which is better, declare an itab with the 'sorted table of' or use the 'sort itab' later.
Thanks in advance!

Hi Kevin,
follow for example more or less the code given in this thread: Functionality to dynamically sort tableview columns and implement a <i>compare</i> method corresponding to your needs (for example using <i>compareToIgnoreCase</i> method of <i>String</i>).
Hope it helps
