1.5: Multiset problem

Hi
There is a problem during debugging procedure with statement like:
ResultTable := ResultTable Multiset Union All SomeOtherTable;
This problem occurs in all Developer versions- when you try to debug procedure it hangs (on 'Finished processing prepared classes'); and it is impossible to close the debug session; if I remove those lines- there is no problem. The problem concerns only debug- procedure works fine anyway.
ps by the way: is there any way I can close debug session, except the red button (which is pretty useless as it is 'grayed' usually)- there is a warning dialoguebox when trying exit Developer with active session- how can I call it without closing?

It looks like you have older versions of AIR installed.
Could you follow the advice in the end of this message:

Update Nested Table Problem

Hi All,
I have a update problem in nested table.

Hi,
I think MULTISET operators might interest you.

Cant deploy the mapping which is validated fine-Problem in debugging

Hi All,
I have a complex mapping with almost thirthy tables involved.
I have created a mapping with step by step process of t1 Join t2 ,t2 Join t3....t29 join t30
The mapping seems fine and was validated succesfully.
When I try to deploy the same it is throwing me the warnings as below...
how to resolve this?
how to pinpoint the exact problem area in pls code generated while deploying.
Thanks Much!

Hi,
there is only one software version. Whether or not you have to license it depends on the features you use.
Generate the code in the mapping editor using the "generate" button
In the generation result window, select generation style = intermediate and operating mode = "[PL/SQL] Set based"
Now you have to select some input or output group of some operator in your mapping.
Then the generation result window displays an SQL statement that represents the data that would go into the group you have selected.
Run the SQL directly in your target schema (using sql*plus, sql developer, etc.).
If the SQL cannot be executed, the problem is in that particular part of the mapping.
You may try to locate it further.
Good luck,
Carsten.

Urgent: export/import problem

Hey there.
I can't import my application anymore into ApEx 2.2,
I took an export from the development application (also 2.2) and wanted to import it into the production environment but i get the next error:
ORA-20001: GET_BLOCK Error. ORA-20001: Execution of the statement was unsuccessful. ORA-06550: line 77, column 19: PLS-00103: Encountered the symbol "F" when expecting one of the following: ) , * & = - + < / > at in is mod remainder not rem <een exponent (**)> <> or != or ~= >= <= <> and or like LIKE2_ LIKE4_ LIKEC_ between || multiset member SUBMULTISET_ <pre>begin --application/shared_com
Error installing application.
Any ideas what could be wrong?
Thank you in advance.
In addition:
I get the same error when importing with mozilla, only the "F" differs:
ORA-20001: GET_BLOCK Error. ORA-20001: Execution of the statement was unsuccessful. ORA-06550: line 77, column 19: PLS-00103: Encountered the symbol "F" when expecting one of the following: ) , * & = - + < / > at in is mod remainder not rem <een exponent (**)> <> or != or ~= >= <= <> and or like LIKE2_ LIKE4_ LIKEC_ between || multiset member SUBMULTISET_ <pre>begin --application/shared_com

Joel,
The problem is solved it seems,
I imported the application with carachter set: West European ISO-8859-1
It gave no problems.
So to resume:
Host DAD WE8ISO8859P1
Imported with character set: West European ISO-8859-1
I now changed the DAD of the target server to WE8ISO8859P1 but that hasn't got anything to do with the problem, i think i choose the wrong character set to import it.
Thanks for the help

CAST MULTISET...is it supported by BI

In a precedent POst i explained the problems we had with multiple queries to display data as a hierarchical manner, with more than 2 levels
We'd like to explore the way with CAST MULTISET...but before to spend time, we'd like to assure that it is supported by BI Publisher.
As an example ( with one level):
We prepared the Object Types as is :
create or replace TYPE ETAG_T AS OBJECT("@S_NUME_OBJE" NUMBER,
                    S_NUME_ETAG NUMBER,
                    C_TYPE_ETAG VARCHAR2(4 CHAR),
                    L_DESC_ETAG VARCHAR2(50 CHAR),
                    N_NOMB_PIEC NUMBER,
                    N_SURF_TOTA NUMBER,
                    D_MODI DATE,
                    R_FONC CHAR(5),
                    R_UTIL CHAR(20),
                    C_CODE_LANG VARCHAR2(4 CHAR)
create or replace TYPE etaglist_t AS TABLE OF etag_t
create or replace TYPE obje_t as Object (
"@S_NUME_OBJE" NUMBER,
N_NUME_IMME VARCHAR2(5) ,
N_NUME_OBJE VARCHAR2(5) ,
etag_list etaglist_t
Then the data query is (Statement is named Q1):
SELECT
obje_t(s_nume_obje, n_nume_obje, n_nume_imme,
CAST (MULTISET (SELECT S_NUME_OBJE,
                    S_NUME_ETAG,
                    C_TYPE_ETAG,
                    L_DESC_ETAG,
                    N_NOMB_PIEC,
                    N_SURF_TOTA,
                    D_MODI,
                    R_FONC,
                    R_UTIL,
                    C_CODE_LANG
FROM imm.b12_0 eta
WHERE eta.s_nume_obje = obj.s_nume_obje)
AS etaglist_t))
AS "obj"
FROM pointi.b02_v obj
WHERE obj.s_nume_obje= :sNumeObje
As a result , we get only the <obj> element like this :
<LIST_Q1>
<Q1>
<obj/>
</Q1>
</LIST_Q1>
We tried too :
SELECT XMLElement("Object",
obje_t(s_nume_obje, n_nume_obje, n_nume_imme,
CAST (MULTISET (SELECT S_NUME_OBJE,
                    S_NUME_ETAG,
                    C_TYPE_ETAG,
                    L_DESC_ETAG,
                    N_NOMB_PIEC,
                    N_SURF_TOTA,
                    D_MODI,
                    R_FONC,
                    R_UTIL,
                    C_CODE_LANG
FROM imm.b12_0 eta
WHERE eta.s_nume_obje = obj.s_nume_obje)
AS etaglist_t))
AS "obj" ) as "objXML"
FROM pointi.b02_v obj
WHERE obj.s_nume_obje= :sNumeObje
And we get :
<Q1>
<objXML/>
</Q1>
Seems to be not supported isn't it...
Laurent

Ok thanks,
I already checked your blog before to speak about pl/sql tables ;-)
I think , for maintenance, it will better too , than having a single query with many cast...Multiset , which could have more than 500 lines :-(
But in our case, as we should have kind of hierarchies in the XML (with levels) and collections, i think we should have a mix :
store pl/sql tables in a package, that will be reused from the main query, and certainly continue to use cast multiset to manage theses nested collections.
As you said, i think we could remove the use of Object Types as we do today.

Problem with OWB Paris (case expression)

I've got a little problem with defining an attribute property. I've defined a simple case statement: case when LKP_IN.TEST_TAB_ID is null then 'INS' else 'UPD' end. When I validate the expression I get the following error message:
Line 1, Col 8:
PLS-00103: Encountered the symbol "when" when expecting one of the following:
. ( * @ % & = - + ; < / > at in is mod remainder not rem
<an exponent (**)> <> or != or ~= >= <= <> and or like LIKE2_
LIKE4_ LIKEC_ between || multiset member SUBMULTISET_
The symbol ". was inserted before "when" to continue.
Line 1, Col 50:
PLS-00103: Encountered the symbol "THEN" when expecting one of the following:
; and or
Needless to say that this worked well with OWB 10g R1. Any clue?
Thanks in advance
Jörg

Hello, Jörg
To what database are you trying to deploy your mapping? It seems that db version is pre-9i?
If so, note that CASE statement is unavailable in PL/SQL until Oracle 9i its available only in SQL (in pre-9i Oracle had different code from SQL and PL/SQL interpretation, after 9i it share interpreter code). The compilation error may appear in ROW-based parts of package: OWB generates code that calls CASE statement directly in PL/SQL it cause error.
To avoid deployment error wrap this expression component by some operator (order, dedup, join, set). In this case OWB pack expression along with wrap operator in SQL statement and package will compile.
Where were discussion here (in forum) about using analytical function in mapping the same approach works for CASE / DECODE if deploying to pre-9i database.

Problem with single quote around ANYINTERACT

CREATE TABLE JUNK
as SELECT s.survey_id,s.shape,s.original_depth
FROM bathyuser.sounding s,m_covr r

WHERE SDO_GEOM.RELATE (s.shape, 'ANYINTERACT', r.geom, 0.5) = 'TRUE'
AND DSNM=CNT.DSNM)';
This above SQL works fine in SQL prompt. But when I put it together in PL/SQL it gives me this error :
WHERE SDO_GEOM.RELATE (s.shape, 'ANYINTERACT', R.geom, 0.5) = 'TRUE'

This is how you go about debugging execute immediate statements. I am assuming that you fixed the first problem as marias suggested and cam up with something like this. Note, I changed the table in your surso to dual since I do not have your tables, but the effect is the same. I changed the EXECUTE IMMEDIATE to DBMS_OUTPUT.Put_Line so you can actually see what you are trying to execute. I also added some carriage returns to make the formatting a littel easier to see. This is what I got:

PL/SQL procedure successfully completed.You have at least two issues with this CREATE TABLE statement. The last line needs to have the X (which came from dual) quoted since it is a string. You also still have a reference to CNT.DSNM, unless you fixed both occurences.
Another major problem is that if your cursor will return more than one row, and by the structure of this I assume that it might, the on the second record you are going to get:
ORA-00955: name is already used by an existing object.
Although I see no reason why you need dynamic sql here, you really need to use bind variables whereever possible (everywhere you use a variable except ofr names of database objects. So, your procedure should look more like:

Perhaps if you can explain in words what you are trying to accomplish someone can provide a much better response.

Hi Frank,
Please chech your object view definition.
are u sure that there will be sigle value populated in the set ArrestWeapons?? your definition says that there will be multiple values and thais is how xmlquery typically handles the nesting.
inside the <ArrestWeapons> ,there will be no of <ArrestWeapons_ITEM> nestings equal to the no of records.
if u do not want this item tag there or two options.
1)try canging the object view definition.i am not sure about your requirements of the xml query. the heriarchy can also be acheived by nested cursors and by objects/nested tables.
2)u will have to manipulate the clob while generating the xml file and delete the unwanted tags.
feel free to post any further queries...

Refer Multiset Union value from cursor

Hi everyone,
I am new to the concept of pseudo functiona and was just trying to use the multiset union function. I have written a cursor which gives me a column 'buyer' and a corresponding dataset. Now my dilemna is how to refer the elements in the dataset using the cursor. Could anyone please help?
CREATE TABLE BUYER
BUYER        NUMBER(4)                        NOT NULL,
BUYER_NAME   VARCHAR2(120 BYTE)               NOT NULL,
BUYER_PHONE VARCHAR2(20 BYTE),

   end loop;
end;
error:
PLS-00302: component 'COLUMN_VALUE' must be declared

Thanks a lot for your help. Now the one i posted was just to simplify the actual problem. But let me try and give you the complete picture.
I have a nested table structure:
Table structure:
                                          ->ExtOfXOrderSkuDesc_TBL -> ExtOfOrderExpDesc_TBL
    I_message -> ExtOfXOrderDesc_TBL
                                          ->ExtOfXOrderPackDesc_TBL -> ExtOfOrderExpDesc_TBLCould not post the whole table detail as its too big
CURSOR c_insert_item IS
   SELECT im.item,
          item_diff.import_country_id,
          item_diff.hts_no,
          item_diff.ExtOfOrderExpDesc_TBL --needs to be casted
     FROM TABLE(CAST(I_message.ExtOfXOrderDesc_TBL(1).ExtOfXOrderSkuDesc_TBL AS "RIB_ExtOfXOrderSkuDesc_TBL")) item_diff,
          item_master im
    WHERE item_diff.style_no = im.item_parent
   UNION ALL
   SELECT im.item,
          pack_diff.import_country_id,
          pack_diff.hts_no,
          pack_diff.ExtOfOrderExpDesc_TBL --needs to be casted
     FROM TABLE(CAST(I_message.ExtOfXOrderDesc_TBL(1).ExtOfXOrderPackDesc_TBL AS "RIB_ExtOfXOrderPackDesc_TBL")) pack_diff,
          item_master im
    WHERE pack_diff.style_no = im.item_parent;Now i need to make an union of all the elements including the ExtOfOrderExpDesc_TBL . So i wanted the cast it as multiset. But pardon my ignorance i feel i am lost somewhere. Based on you reply could you suggest how can i make the union and access each element using the cursor record?
Thanks

A problem with threads

I am trying to implement some kind of a server listening for requests. The listener part of the app, is a daemon thread that listens for connections and instantiates a handling daemon thread once it gets some. However, my problem is that i must be able to kill the listening thread at the user's will (say via a sto button). I have done this via the Sun's proposed way, by testing a boolean flag in the loop, which is set to false when i wish to kill the thread. The problem with this thing is the following...
Once the thread starts excecuting, it will test the flag, find it true and enter the loop. At some point it will LOCK on the server socket waiting for connection. Unless some client actually connects, it will keep on listening indefinatelly whithought ever bothering to check for the flag again (no matter how many times you set the damn thing to false).
My question is this: Is there any real, non-theoretical, applied way to stop thread in java safely?
Thank you in advance,
Lefty

This was one solution from the socket programming forum, have you tried this??
public Thread MyThread extends Thread{
     boolean active = true;
     public void run(){
          ss.setSoTimeout(90);
          while (active){
               try{
                    serverSocket = ss.accept();
               catch (SocketTimeoutException ste){
               // do nothing
     // interrupt thread
     public void deactivate(){
          active = false;
          // you gotta sleep for a time longer than the
          // accept() timeout to make sure that timeout is finished.
          try{
               sleep(91);
          }catch (InterruptedException ie){
          interrupt();
}

You can also try to provide a greater Priority to your player thread so that it gains the CPU time when ever it needs it and don't harm the playback.
However a loop in a Thread and that to an infinite loop is one kind of very bad programming, 'cuz the loop eats up most of your CPU time which in turn adds up more delays of the execution of other tasks (just as in your case it is the playback). By witting codes bit efficiently and planning out the architectural execution flow of the app before start writing the code helps solve these kind of issues.
You can go through [this simple tutorial|http://oreilly.com/catalog/expjava/excerpt/index.html] about Basics of Java and Threads to know more about threads.

N.B. And yes there are more articles and tutorials available but much of them targets the Java SE / EE, but if you want to read them here is [another great one straight from SUN|http://java.sun.com/docs/books/tutorial/essential/concurrency/index.html] .

J2ME problem with threads

Hi all,
I would like to ask you for a help. I need to write a small program at my university. I started to write a midlet which function would be to countdown time for sports activities. I woul like to start a new thread - the one that counts down - and at the same time make the main thread sleep. After the "countdown" thread finishes, the main thread wakes up and waits for user input. The problem is that when the "countdown" thread finishes his work, I've got Uncaught exception java/lang/NullPointerException. error and the midlet halts.

Groovemaker,
Your Licznik class has a member m of type monitor, which has not been instantiated (in other words is null) hence, when calling m.put() you get NullPointerException. Please also mind, that using Thread.sleep(1000) is not an accurate way of measuring time.
If I may, please use recommended for Java class naming conventions - some of your names use lower case, while other don't which is confusing to the reader.

Problem with threads within applet

Hello,
I got an applet, inside this applet I have a singleton, inside this singleton I have a thread.
this thread is running in endless loop.
he is doing something and go to sleep on and on.
the problem is,
when I refresh my IE6 browser I see more than 1 thread.
for debug matter, I did the following things:
inside the thread, sysout every time he goes to sleep.
sysout in the singleton constructor.
sysout in the singleton destructor.
the output goes like this:
when refresh the page, the singleton constructor loading but not every refresh, sometimes I see the constructor output and sometimes I dont.
The thread inside the singleton is giving me the same output, sometime I see more than one thread at a time and sometimes I dont.
The destructor never works (no output there).
I don't understand what is going on.
someone can please shed some light?
thanks.
btw. I am working with JRE 1.1
this is very old and big applet and I can't convert it to something new.

Ooops. sorry!
I did.
     public void start() {
     public void stop() {
     public void destroy() {
          try {
               resetAll();
               Configuration.closeConnection();
               QuoteItem.closeConnection();
          } finally {
               try {
                    super.finalize();
               } catch (Throwable e) {
                    e.printStackTrace();
