JDBC string- number conversion in Canadian locale

How come Oracle JDBC driver thinks "2.1" is an invalid number in Canadian locale? The decimal point in Canadian locale is still "." as used in US locale. It is easy to verify this by changing your locale to English (Canada) and check the "Number" settings on your Windows machine.
This is definitely a bug. Can antone from Oracle confirm this?
Thanks.

It is working now because you have imported oracle.jbo.domain.Number and hence not using java.lang.Number.
java.lang.Number is a abstract class and hence no constructors, whereas oracle.jbo.domain.Number has many constructors (one of which Srinath suggested to use.)
you can still make it work with
oracle.jbo.domain.Number n = new oracle.jbo.domain.Number(businessReqID) ; //if businessReqID is a String.
You dont need to get the int from the String in order to use this constructor.
Thanks

String/number conversion

I am trying to convert a number in a string (a SPICE netlist) to a double. The string contains extra letters. Is there a String or double (or float) method that safely converts without vomitting on unwanted characters?
And by the way, I used to (about 1+ years ago) be able to look at a reference online that gave a detailed description of the Java standard class methods. Know where I might find this?

Re: Error, numeric or value error: character to number conversion error

Can someone please please tell me why I'm getting this error and what I'm doing wrong? It looks like a simple error, "numeric or value error: character to number conversion error".
My code is as follows:
string connectionString = WebConfigurationManager.ConnectionStrings["DEMO_TEST"].ConnectionString;
OracleConnection con = new OracleConnection(connectionString);
OracleCommand cmd = new OracleCommand("DEMO.PKG_LOCATION_TYPE.INS", con);
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Add(new OracleParameter("@P_DESCRIPTION", OracleDbType.Varchar2, 60));
cmd.Parameters["@P_DESCRIPTION"].Value = "Test_Description";
cmd.Parameters.Add(new OracleParameter("@P_NAME", OracleDbType.Varchar2, 6));
cmd.Parameters["@P_NAME"].Value = "Test_Name";
cmd.Parameters.Add(new OracleParameter("@P_LOCATION_TYPE_CD", OracleDbType.Decimal, 4));
cmd.Parameters["@P_LOCATION_TYPE_CD"].Direction = ParameterDirection.InputOutput;
con.Open();
try
cmd.ExecuteNonQuery();
catch
//In case of an error
finally
con.Close();
con.Dispose();
And I recieve the following error block:

Are the parameters in your procedure in the same order as they are created in this code? Oracle command works by position unless you change it to be BindByName.
Failing that you seem to have defined a parameter (P_NAME) to have a length of 6, and are then setting it's value to a string with a length of 9.
Also the in/output parameter is defined as type decimal. Is this correct? It is defined as InputOutput but you don't assign it any value.
If these suggestions don't help then perhaps if you post the stored procedure you might get some more ideas.

ORA-06502: PL/SQL: numeric or value error: character to number conversion

Hello,
I am new to Oracle Apex so I decided to read and do the tutorials that are on the apex.oracle.com site.
Now I am at the tutorial 6: How to Work with Check Boxes of the Advanced Tutorials.
At a certain point you have to add a new radio button.
At the Item Source Value you have to add SELECT 'Y' FROM DUAL WHERE :P2_LIST_PRICE*0.75=:P2_MIN_PRICE.
But when I try to create the item, I keep getting the following error:
ORA-06502: PL/SQL: numeric or value error: character to number conversion error
Error creating item.
Does anybody know what could be the problem.
Thanks in advance.

Here I m passing a string variable to pass the select statement for the ref cursor.
There seems some problem in the substr conversion in the statement.

But when i run as a independent staement passing real values in the place of placeholders
i get the result right.
The *:PERIOD_NAME* format is *'Jan-2009-10'* .
And I need to pass the *:PERIOD_NAME* to the query as *'Jan-09-10'*
Pls suggest.

FM for Material number conversion from R/3 to APO in R/3

Hi,
   Can anybody tell me conversion exit (function module) for Material number conversion from R/3 to APO in R/3 system. I mean i have 18 digit R/3 material number which i have to convert to 40 digit APO material number in R/3 system.
Please suggest to win full points.
Thaniks in Advance,
Chandan Dubey

Dear Chandan,
Conversion Exits:
CONVERSION_EXIT_MATN1_INPUT ....... If you are storing Material With Zeros
Then concatenate it with 22 zeros. i.e. '0000000000000000000000000000'.
For example:
data : v_matnr type matnr,            "R/3 Material
       v_apo_matnr(40) type c,        "APO Material with 40 length
       v_zeros(22) type c. value '0000000000000000000000000000'.
CALL FUNCTION 'CONVERSION_EXIT_MATN1_INPUT'
       EXPORTING INPUT          = v_matnr
       IMPORTING OUTPUT         = v_matnr.
concatenate e_mantr v_zeros into
            v_apo_matnr.
Regards,
Naveen.

Numeric or value error: character to number conversion error

I'm having problems inserting a value from a date picker field (DD-MON-YYYY HH MI )
i'm submitting this value to a packaged procedure that accepts this field as VARCHAR2 .
on the insert, i do a to_date( P_DATE, 'DD-MON-YYYY HH:MI PM' )
and i get the numeric conversion error.
If I change the to_date on the procedure side, I get the :could not read the end of the format mask - which I've found threads about on this site.
I've tried using HH24 and different formats, but I get one of the two above errors on the insert.
If I don't fill in the datepicker field at all, it works fine.
help is appreciated !
Bill

PL/SQL: numeric or value error: character to number conversion error in TRG

Hi,
I've got strange issue with one trigger which during update of table reports (DB is 9.2.0.8):
ORA-06502: PL/SQL: numeric or value error: character to number conversion error
ORA-06512: at "UDR_LOG", line 345
ORA-04088: error during execution of trigger 'UDR_LOG'but line 345 is:
END IF;
so its kind of strange
the code looks like
343 IF nvl(to_char(:old.PKD_ID),'''') <> nvl(to_char(:new.PKD_ID),'''') THEN
344 v_zmn := v_zmn || 'PKD_ID''' || to_char(:old.PKD_ID) || '''' || to_char(:new.PKD_ID) || '''';
345 END IF;
so its concatenation not to_number usage .error is triggered by update statement on any column .
I'm sorry I cant provide You with whole trigger code .
So if You could only recommend any investigation method that would be great .
Regards
Greg

Hi, Greg,
When there's an error in a trigger, the line numbers in the error messages are relative to the first DECLARE or BEGIN statement; often, that's a few lines after CREATE OR REPLACE TRIGGER. Post a few lines after what you already posted.
If you can't find the error, then create another table for testing this, and create a smaller trigger on that table, which does only enough to cause the error. Then you'll be able to post the complete trigger, and the code needed to re-create the problem.

    Statement "CALL SCREEN" is not allowed in this form.
What happened?
    Error in ABAP application program.
    The current ABAP program "SAPLSHL2" had to be terminated because on
    statements could not be executed.
    This is probably due to an error in the ABAP program.
Error analysis
    There is probably an error in the program
    "SAPLSHL2".
    The program was probably called in a conversion exit
    or in a field exit. These are implemented by
    function modules called CONVERSION_EXIT_xxxxx_INPUT/OUTPUT or
    USER_EXIT_xxxxx_INPUT.
    Conversion exits are triggered during screen field transports or
    WRITE statements, field exits during field transports from the
    screen to the ABAP/4 program.
    In this connection, the following ABAP/4 statements are not allowed:
    - CALL SCREEN
    - CALL DIALOG
    - CALL TRANSACTION
    - SUBMIT
    - MESSAGE W... and MESSAGE I...
    - COMMIT WORK, ROLLBACK WORK
    - COMMUNICATION RECEIVE
    - STOP
    - REJECT
    - EXIT FROM STEP-LOOP
    Moreover, conversion exits for output conversion
    (implemented by function modules called
    CONVERSION_EXIT_xxxxx_OUTPUT) do not allow
    - MESSAGE E...

What could cause the problem by selecting only 0Material when checking the InfoCube 0PUR_C01 content? What does that mean by this STOP msg "Settings for material number conversion not found"?
Thanks

Hi Kevin,
Set the length of 0MATERIAL and change conversion to alpha:

Maximum Number of Objects in Local History does not work

In our Production system, I have configured the Maximum Number of Objects in Local History to be '10'. I do not see any queries in the dropdown. I have executed and changed queries since I made this change. None of the users can see a history log.
In our Dev system, the Maximum Number of Objects in Local History is working as expected.
Is there a system-wide setting that overrides my personal setting?
Thanks.

you could have a consolidated DSO with the keys alone and see if you can have an alternate design using an infoset instead....

ORA-06502: numeric or value error: character to number conversion error

I met the following error when I ran Donald's PL/SQL function to_number_or_null. Could somebody here help me find the resolution? Thanks!

10 return to_number(aiv_number);

Only INVALID_NUMBER exception is handled and also VALUE_ERROR should be handeled. You can resolve it by handling VALUE_ERROR exception or by adding WHEN OTHERS as I did in following example.
SQL> create or replace FUNCTION to_number_or_null (
2      aiv_number in varchar2 )
3      return number is

10     return to_number(aiv_number);
11     exception
12     when INVALID_NUMBER then
13      return NULL;
14     when OTHERS then
15      return null;
16     end to_number_or_null;

Return 2 values (string, number) multiple rows, from java stored function

I would like to return 2 values (String, number prefered but String, String will work) from a java stored function.
I was able to successfully return a varray of varchar2 values but I was wondering if it is possible to return 2 values by using a varray?
Is it even possible? I tried using combinations of types which included a varray of objects (with 2 attributes) or a type as table of objects but I couldn't figure out how in my java code to set these values. Also what would my java function return type be and what Oracle type would map to it?
Any help and examples or pointers would be great.
Thanks,
Dennis

Thanks to all. I finally figured it out through all the pieces on the web.
Here is what worked for me. First create 2 oracle types. One object type to represent the "columns" I will pass back:
CREATE OR REPLACE TYPE COST_OBJ AS OBJECT (COST_NAME NVARCHAR2(50), COST_VALUE number ) NOT FINAL
note: make sure the "strings" are defined as NVARCHAR2 or Java will puke if it is just VARCHAR2.
Then create a table type to hold your objects defined as following:
CREATE OR REPLACE TYPE COST_OBJ_TABLE is table OF COST_OBJ
Then create the oracle stored function that is a wrapper to the java function:
CREATE OR REPLACE FUNCTION get_Costs(Name VARCHAR2, evalDate VARCHAR2, fuelCodeID NUMBER) return COST_OBJ_TABLE
is language java name
'com.costs.storedProcedures.Cost.getCosts(java.lang.String, java.lang.String, int) return oracle.sql.ARRAY'
Once that is done, Oracle is ready. The Java function looks something like this:
public ARRAY getCosts(String name, String evalDate, int fuelCodeID) {
DBAccess da = getDBAccess();
// get a handle on the connection
Connection conn = da.getConnection();
// The stuff that will be returned should be as type object array
// make it to the size of the number of fuelcomponents passed in
Object[] returnStuff = new Object[3];
// create the type of struct that is defined on the database
StructDescriptor structDesc =
StructDescriptor.createDescriptor("CY_UMAP.COST_OBJ", conn);
for (int i = 0; i < returnStuff .size(); i++) {
Object[] costValues = new Object[]{
     "This is object " + i,
     new Integer ( i ) };
STRUCT cost_obj = new STRUCT(structDesc, conn, costValues);
returnStuff[i] = cost_obj;
ArrayDescriptor x_ad = ArrayDescriptor.createDescriptor (
"CY_UMAP.COST_OBJ_TABLE", conn);
ARRAY x_array = new ARRAY(x_ad, conn, returnStuff);
return x_array;
I hope this helps others.

How to send really Chinese word, not the string "&# number " to web browser

Each Chinese word on page sending to web browser is translated to a string in form "&#<number>" by default, it's a problem when Chinese word is included in url. How to specify sending really Chinese word, not the string "&#<number>" to web browser?

Thanks that seems to make much more sense, still having some troubles though.
Ok so now the majority of it seems to be working and it seems to be sending the String just fine. And I'm having it send the String to the BufferedWriter "out" and then using the newLine() method to send a carriage return but the BufferedReader on "in" seems to not detect the carriage return.
I have it doing a readLine() so that (as I understand it) it should be blocking, waiting until an end of line character so I assume each call of newLine() should have it pick up something but a quick breakpoint shows that it never stops blocking on readLine().
I assume the connection is fine because the application running as server uses the socket object returned by the accept() method.
Is there something I've perhaps misunderstood about the BufferedReader's readLine() method?
Here's the new version of my netbeans project:
http://rapidshare.com/files/371224512/KerazehDood.rar
Also on a different line of questioning, I'm just wondering about socket convention.
I was thinking it'd be useful in a game similar to what I'm attempting to make to not only send player position information but also client keypress information, I was just wondering, if you're doing something like that would it be frowned upon to use two separate ports? I think it would make the implementation far more legible and easy to structure but wasn't sure if applications usually try to stick to only one port or not.
Thanks.
