LoadVars dataType problem

hello,
i have some variables sent out of flash in a LoadVars object,
later to be returned with the same values...
i have done "trace (typeof (variable));" before sending it
out, which tells me that "variable" is a Number, which it should
be.
i do it again upon Loadvars.load, and it is a string....
strange because a different variable goes out as a Number and
comes back as a Number...
does anyone have an idea why this happens?
thanks.

my bad-
i think what happened is that i "re-declared" the one that
tells me it's a Number on the return page...
is this what i have to do for all incoming variables that are
NOT supposed to be strings?
or is there a way to CHANGE data type from String to Number?
thanks

Datatype problem in project euler

Today I had nothing to do, so I participated in Project Euler http://projecteuler.net with Labview. I'm at question 10 now. The question itself isn't much of a challenge, but the problem I'm having is that the datatypes are to small for the value I would like to put in there. The value first goes up, then changes from + to - and then goes back to zero. This all happens while I'm just adding up to the value.
I guess there is a sollution to this problem but I don't seem to find it. Is there someone who can and will help me please?

Well, the link you gave said problem 10 was "Find the sum of all the primes below two million", a little different problem than 2^1000.
In order represent 2^1000 at full resolution, you would need a 1000 bit number! Of course a U64 won't be able to hold it. A double will hold it and it comes to about 1.07...e301, so 301 decimal digits. But a double won't store the full resolution.
In order to do what you want, you will have to set up your own math functions using 125+ bytes. You will have to do the multiplication and do all of your own carries. That why they made it a problem, to challenge you to figure out the algorhitm to do it. Otherwise going 2^1000 in any programming language is a trivial exercise.

Problem of LOV, Datatype Problem

hi experts
When i applied an LOV on Supplier ID field which is foreign key, i am getting this error please see the Snapshot of form.
http://1.bp.blogspot.com/-JsNiNnjdoyg/T5KGcPpzlCI/AAAAAAAAAOk/a51eItBrDWM/s1600/Capture-1.PNG
Datatype of supplierID in Child Table is Integer while in parent table it is type of DBSequence. I have also apply sequence in database.
One Very Important thing is that i am using lot of LOVs in My project but i am not getting this type of error in any LOV. I am using same techniques in other LOVs. I have not any
problem in database.
Please help me to solve this problem.
Thanks.........Regards
Muhammad Nasir

In Record group of second LOV(EMPLOYEES) insert where-clause like:
where emp.DEPTNO = :DEPTNO_you get_from_first_lov
P.S. Please, do better if you write in lowercase, It would be more readable

Datetime Datatype problem in Forms

Hi,
I have just faced a problem some moment ago in Oracle Forms . Firstly , informed you that i am using Forms [32 Bit] Version 10.1.2.0.2 (Production)
Ok, i have a field named ENTRY_TIMESTAMP. I kept 'Datetime' datatype there in forms level. Now if i change anywhere on that particular form, ENTRY_TIMESTAMP datatype changed from 'Datetime' to 'Date'. You can also check it by making a form of this scenario.
I don't know , is it a bug or any others code/process is responsible for this kind of changing ?
Any idea ?????????????

Exactly i don't know, is it bug ? but thinking so as same case happened for form version 6i
But it not happened for form version *10.1.2.3* To upgrade you need patchset from support.oracle.com / metalink.
If your have valid support contact then you can able to download.
Hope this helps

Oracle Spatial datatype problems - HELP!!

Can anyone help with this problem. I am using Pro*C/C++ to create a DLL which I am then
linking to another C based application. I am attempting to use Pro*C/C++ to read/write
Oracle Spatial Objects. I have no problem writing Pro*C/C++ code or accessing the
functions in the DLL. My problem is returning values from the DLL functions to my
application. So far the only values I seem able to return are character strings.
Below are two versions of the same function. One that returns a char string and a second
that returns nothing. I would like the second function to work and to return an integer
value for "g_type". Any ideas??? By the way "g_type" is the return value in question. I am
using Oracle Pro*C/C++ 8.1.5 and the V8 Oracle Call Interface for the datatype conversion.
Header files for the Object types have been generated by the Object Type Translator.

Hi,
From a quick look I can't see anything wrong. You might want to compare this with the example in $ORACLE_HOME/md/demo/examples.
Also, note that in 9i there will probably be an occi (C++ OCI) available, should this be useful to you.

Strange Datatype Problem

Can anyone explain why I can't get these values to insert into my tables using a created data page in one of my APEX applications. The error I get is "ORA-01481: invalid number format model". I am able to insert these values manually by inserting a row in the object browser. This happens when importing a CSV or a tab separated list. I'm using APEX 4.1

Inconsistent datatypes problem (ORA-00932)

Hi all,
Given the following two tables , located in two different schemas :
CREATE TABLE schema1.national_desc
(     ENT CHAR(18 CHAR),
     COD_MAJ CHAR(1 CHAR),
     SID_DESC_COD_ADD NUMBER(8,0),

UNION
SELECT
'0',
sid_cod_add,
l_desc,
NULL,
NULL
FROM
F24510
where
id_lang='FR'and Oracle complains with this error : ORA-00932.
We have tried to "cast" the L_DESC column with TO_CHAR but some column value exceeds 4000 chars.
Casting with TO_CLOB give the same first error.
Any idea ?

Hi ,
Thanks for your reply. We have finally find the problem :)
Instead of UNION, we perform an UNION ALL. With UNION Oracle had to check unicity
between rows containing NCLOB columns...
Hopefully, in our case UNION ALL does the trick !

Table(cast - invalid datatype problem

Hi All,
Basic scenario:
PACKAGE
create or replace
PACKAGE C2_PAYMENT_DOC IS
TYPE bin_array IS TABLE OF NUMBER
INDEX BY BINARY_INTEGER;
FUNCTION test_fun(l_doc_id IN integer) RETURN bin_array;
PACKAGE_BODY
create or replace
package body C2_PAYMENT_DOC as
FUNCTION test_fun (l_doc_id IN integer) RETURN bin_array IS
l_gross bin_array;
begin
c2_purchase_invoice.get_inv_gross_amount(l_doc_id, l_gross(1));
return l_gross;
end;
END;
QUERY
select * from Table(Cast(c2_payment_doc.test_fun(1) As bin_array));
Result of the query is ORA-00902: invalid datatype
How can I make the select statement valid?
Thanks in advance,
Bartek

You can not use local collection types in SQL. You must create type bin_array as SQL nested table type. Also, depending on version you might not need to cast:
SQL> CREATE OR REPLACE
2    TYPE bin_array
3      AS TABLE OF NUMBER
4 /
Type created.
SQL> create or replace
2   PACKAGE C2_PAYMENT_DOC IS
3 FUNCTION test_fun(l_doc_id IN integer) RETURN bin_array;
4 end;
5 /
Package created.
SQL> create or replace
2 package body C2_PAYMENT_DOC as
3
4 FUNCTION test_fun (l_doc_id IN integer) RETURN bin_array IS
5 l_gross bin_array := bin_array();
6 begin
7      l_gross.extend;
8      l_gross(1) := l_doc_id;
9 return l_gross;
10 end;
11 END;
12 /
Package body created.
SQL> select * from Table(Cast(c2_payment_doc.test_fun(1) As bin_array));

           1

Sybase ODBC driver - numeric or decimal datatype problem

Hello!
I have Sybase Adaptive Server Enterprise 15.0.2 and Oracle 10.2.0 ("show release" in SQL*plus prints 1002000100) on the same machine (OS = Windows XP, name = Workstation). I wanna load correct information from the table in Sybase via Oracle database link.
Well, I've edited tnsnames.ora, listener.ora. Also I've created initmysybase.ora in hs\admin directory. And, of course, set up DSN (using Sybase ODBC driver) via odbcad32.exe - and named it "mysybase".
Table ("test", user = guest) definition in Sybase is:
column "id" - int, column "data_num" - numeric(10, 5), column "data_dec" - decimal(10, 5). And it's content is: (1, 1.12345, 5.54321). I've set up a database link.
My problem is that whenever I do the SELECT statement (SELECT * FROM "guest.test"@mysybase) I get 0 (zero) for both data_num and data_dec columns.
Status of investigation:
The "describe" command in SQL*plus returns:
id NOT NULL NUMBER(10)
data_num NUMBER(10,5)
data_dec NUMBER(10,5)
UPDATE statement works perfectly.
I've downloaded a trial version of ODBC drivers from www.datadirect.com and all works fine.
So, I believe that maybe there are some bugs in ODBC driver from Sybase, or maybe I should configure smth.
My initmysybase.ora:
HS_FDS_CONNECT_INFO = mysybase
# HS_FDS_TRACE_LEVEL = DEBUG
HS_FDS_TRACE_LEVEL = ON
HS_NLS_NUMERIC_CHARACTER = ",."
HS_LANGUAGE = American
tnsnames.ora:
mysybase =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = WORKSTATION)(PORT = 1521))
(CONNECT_DATA =
(SID = mysybase)
(HS = OK)
listener.ora:
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
(ADDRESS = (PROTOCOL = TCP)(HOST = WORKSTATION)(PORT = 1521))
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = mysybase)
(SID_NAME = mysybase)
(ORACLE_HOME = C:\oracle\product\10.2.0\db_1)
(PROGRAM = hsodbc)
So, maybe anybody know how to solve this problem?
Thanks,
Yury

Datatype Problems between Java and COBOL

I am calling a COBOL stored procedure from a Java Servlet. The COBOL stored procedure needs compressed numeric values and Java sends it Integer values. I'm getting an error saying my parameters don't match up. I'm wondering if it's because COBOL needs a compressed value. Has anyone else dealt with this or a similar problem? Please HELP!!!!
Thanks so much.

I need to add more information...
I am using JDBC. I am passing in 4 parameters from my Java code: 2 shorts and 2 ints. In the COBOL parameter definition they are 2 SMALLINTs and 2 INTEGERs. In the COBOL stored proc the 2 SMALLINTs are S9(04) comp and the 2 INTEGERs are S9(09) Usage comp. Example values that I am passing in are:
(short) 2000
(short) 22
(int) 1749
(int) 164
The stored procedure is on a DB2 database. Hopefully this gives you a little more information to go on...
Thanks.

Parameters DataType Problem

if i create a parameter of type Date in crystal reports and the then try to select records based on the value of this parameter, i am simply not able to do this because when i go to select record section of report then i select the field of sql table, select comparison operator ,when i try to select the parameter created above, its not there in the list because parameter is of type Date and the sql field is of type smalldatetime.
i want the report's parameter to be date only but there is no datatype of Date in sql server.
Solution?

If the date parameter isn't showing up in the list of available options in the Selection Expert... Try adding it to the formula manually:
{TableName.SmallDateField} > {?DateParameter}

Flash LoadVars textfile problem

I'm using a loadvars action to load external .txt file, and
it loads the file BUT only will read numbers out of the file.
It won't read letters-which make words- which make
sentences-which makes me angry.
Any idea why this would be? I've tried playing around with
the .txt file encoding, would it be something in the AS code? (even
thought it has to be loading the file since it is reading the
numbers.)
Any suggestions?

ok. code will follow
Whats wrong is :
I'm loading external text files (.txt) but only numbers are
showing up when loaded. It is loading numbers, so it's pulling the
right file, but it won't display any letters from the text file. I
have tired changing encoding on the .txt file with no (correct)
results.
SO basically... what would cause flash to load numbers but
not letters from an external .txt file?
note* (code uses curFrameNum in textfile name to match text
files to picture files, but that works, its just not displaying the
loaded text completely/ correctly)
Code:
// -----------------<Loading captions
A.S.>---------------- \\
frameNum.autoSize = "center";
loadedInfo.autoSize = "Left";
//--------------triger the mcl to
load------------------------\\
//myMCL.loadClip("",);
//myMCL.loadClip("slideshow2.swf",1)
//---------------LoadVars----------------------\\
var myLV:LoadVars = new LoadVars();
myLV.onLoad = function (success) {
if (success) {
loadedInfo.htmlText = true;
loadedInfo.htmlText = myLV.info;
} else {
loadedInfo.text = "There has been an error loading the
requested pictures."
//--------slide counter----------\\
var slideInfoLV:LoadVars = new LoadVars();
slideInfoLV.onLoad = function (success) {
if (success) {
slideCounter();

Datatype problem while using copy command

Hi all,
I an using copy command to copy data
SQL> copy from xyz/abc@xxx to aaa/sss@aaa create Table1(Name,duration) using select * from Table2The problme is in Table2 duration is like 4.5,but when after copying in Table1 it is coming as 4 .
Could someone help me in fixing this ?
rgds,
Karna

try not defining the columns first, the create will do that.
copy from xyz/abc@xxx to aaa/sss@aaa create Table1 using select * from Table2
I am assuming the table2 only contains the two columns.
