Calling an Oracle function of BOOLEAN return type

I am facing a situation, where I have defined an overloaded function in one package (2 variants) which both return a type BOOLAN value under Oracle 9i R1.
I am having trouble to setting up an CallableStatemnt to call one of this functions from Java. Whenever I set the parameter with a BIT or NUMBER data type, I get an exception with java.lang.boolean during my
callablestatement.setobject( index, parameter, OracleTypes.BIT );
or
callablestatement.setobject( index, parameter, OracleTypes.NUMBER );
I have no problem calling the function from SQLPlus, but doing so from Java raises the exception. I have found no exact match in OracleTypes or java.sql.Types for a BOOLEAN data type.
In your response do you mean to modify the Function to return a NUMBER instead of a BOOLEAN, or do you mean to set the parameter as Types.NUMBER in the calling java code?
Thanks,
Fedro

Call to Oracle stored procedure that returns ref cursor doesn't work

I'm trying to use an OData service operation with Entity Framework to call an Oracle stored procedure that takes an number as an input parameter and returns a ref cursor. The client is javascript so I'm using the rest console to test my endpoints. I have been able to successful call a regular Oracle stored procedure that takes a number parameter but doesn't return anything so I think I have the different component interactions correct. When I try calling the proc that has an ref cursor for the output I get the following an error "Invalid number or type of parameters". Here are my specifics:
App.config

I defined a function import for the stored procedure using the directions I found online by creating a new complex type. I don't know if I should be defining the input parameter, WindfarmId, in my app.config? If I should what would that format look like? I also don't know if I'm invoking the stored procedure correctly in my service operation? I'm testing everything through the rest console because the client consuming this information is written in javascript and expecting a json format. Any help is appreciated!

Making the change you suggested still resulted in the same Oracle.DataAccess.Client.OracleException {"ORA-06550: line 1, column 8:\nPLS-00306: wrong number or types of arguments in call to 'GETWORKORDERSBYWINDFARMID'\nORA-06550: line 1, column 8:\nPL/SQL: Statement ignored"} System.Exception {Oracle.DataAccess.Client.OracleException}
I keep thinking it has to do with my oracle.dataaccess.client settings in App.Config because I don't actually put the WindfarmId and an input parameter. I tried a few different ways to do this but can't find the correct format.

XI calling an Oracle Stored Procedure which returns an Object to XI

I am currently trying to call an Oracle Packaged/Procedure from XI which accepts a couple of parameters as I/O and returns an Object as one of the parameters.
I have created the Object within the Oracle Database CREATE OR REPLACE TYPE xy_jdbc AS OBJECT
column_name type ...etc
CREATE OR REPLACE TYPE xy_tab_jdbc AS TABLE OF xy_jdbc;
One of the parameters for the stored procedure is set up as this type xy_tab_jdbc this will be populated based upon one of the parameters passed into the Package/Procedure.
Is this possible? If it is, how do I map the returned object within XI?

Dear Hilary,
the JDBC adapter does not support vendor-specific or non-scalar data types.
Workaround: Change the stored proc's signature not to use an object, but the object's fields instead.

Thilo

How to call a Oracle Proc,which contains Object Type as in Param, from java

Hi
Would like to know how to call a Oracle Procedure which contains the Object Type Parameter from java.
Here is my code will look like...
1. CREATE OR REPLACE TYPE emp AS OBJECT
Empno NUMBER,
Ename VARCHAR2(50)
[COLOR=royalblue]In step1 I have created object type.[COLOR]
2.CREATE OR REPLACE PACKAGE ref_pkg IS
TYPE tab_emp IS TABLE OF emp;
END ref_pkg;
[COLOR=royalblue]In step2,I have created a table type which is of type emp;[COLOR]
3. CREATE OR REPLACE PROCEDURE p_emp(p_emptab IN ref_pkg.tab_emp) as
BEGIN
FOR I IN 1..p_emptab.COUNT
LOOP
Some code written here
END LOOP;
END;
[COLOR=royalblue]In step3 I have passed tabletype which is of type emp as argument.[COLOR]
Now I need to invoke this procedure from JAVA.
Calling a procedure doesn�t matter.
But how I can map objecttype ? how will java recognize oracle object ?
How can I implement this ?
Any Help/Clues is Appreciated.
Thanks

Hi Bob
You can call a stored proc from a database control with the jc:sql annotation itself.
Assume a stored proc taking one In parameter
* @jc:sql statement="call sp_updateData({id})"
void call_sp_updateCust(int id);
You can even call stored proc with OUT parameters using
* @jc:sql statement="{call sp_MyProc(?, ?)}"
void call_sp_MyProc(SQLParameter[] params)
You can also call stored functions via db control.

Function overloading on return types

consider following two overloaded functions
public int functionA(int a,int b);
public char functionA(int a,int b)and if i call them like this
int returnInt = functionA(a,b)
char returnChar = functionA(a,b)in this scenario which function to call can be decided depending on the
return type then why java don have overloading on the basis of return type ?

Try it.

Same functions with different return types in C++

Normally the following two functions would be considered the same:
int getdata ( char *s, int i )
long getdata ( char *s, int i )
Every other compiler we use would resolve both of these to the same function. In fact, it is not valid C++ code otherwise.
We include some 3rd party source in our build which sometimes messes with our typedefs causing this to happen. We have accounted for all of the function input types but never had a problem with the return types. I just installed Sun ONE Studio 8, Compiler Collection and it is generating two symbols in our libraries every time this occurs.
Is there a compiler flag I can use to stop it from doing this? I've got over 100 unresolved symbols and I'd rather not go and fix all of them if there is an easier way.

Normally the following two functions would be
considered the same:
int getdata ( char *s, int i )
long getdata ( char *s, int i )Not at all. Types int and long are different types, even if they are implemented the same way.
Reference: C++ Standard, section 3.9.1 paragraph 10.
For example, you can define two functions
void foo(int);
void foo(long);
and they are distinct functions. The function that gets called depends on function overload resolution at the point of the call.
Overloaded functions must differ in the number or the type of at least one parameter. They cannot differ only in the return type. A program that declares or defines two functions that differ only in their return types is invalid and has undefined behavior. Reference: C++ Standard section 13.1, paragraph 2.
The usual way to implement overloaded functions is to encode the scope and the parameter types, and maybe the return type, and attach the encoding to the function name. This technique is known as "name mangling". The compiler generates the same mangled name for the declaration and definition of a given function, and different mangled names for different functions. The linker matches up the mangled names, and can tell you when no definition matches a reference.
Some compilers choose not to include the return type in the mangled name of a function. In that case, the declaration
int foo(char*);
will match the definition
long foo(char*) { ... }
But it will also match the definitions
myClass foo(char*) { ... }
double foo(char*) { ... }
You are unlikely to get good results from such a mismatch. For that reason, and because a pointer-to-function must encode the function return type, Sun C++ always encodes the function return type in the mangled name. (That is, we simplify things by not using different encodings for the same function type.)
If you built your code for a 64-bit platform, it would presumably link using your other compilers, but would fail in mysterious ways at run time. With the Sun compiler, you can't get into that mess.
To make your program valid, you will have to ensure your function declarations match their definitions.

OTL call for oracle function

Hi,
I created a Oracle function like get_employee_id() which will return the employee id if the name and department exists.
If not exists it will insert the record and return the emp_id.
get_employee_id(name,department)
if name and department exists id will be returned
else record will be inserted and emp id will be returned.
emp_id is a sequence which will be triggered to auto increment.
Problem is::
Not getting a correct way to access get_employee_id() from OTL interface.
I am trying like
query << "BEGIN :3<int> := get_employee_id(:1<char[128]>,:2<char[1024]>); END;" ;
otl_stream oos(1, query.str().c_str(), db());
oos << emp_name ;
oos << emp_dept ;
while(true){
oos >> emp_id ;
if(!oos) break ;
Please let me know what is the correct way of accessing this.Thanks for the help in advance.

     balanceobjct := fnc_convertBalance(cursor_billing, 'BALANCE','BALANCETYPE');
return balanceobjct;
END bpm_art_rpt_account_balance;
When i call this function from the Oracle DB with a DB GUI everything works fine, but when i call it from a BPEL Process i get the following error
ORA-00932: inconsistent datatypes: expected OUT Conversion failed got ORA-06512: at "ARBOR.FNC_CONVERTBALANCE", line 0 ORA-06512: at "ARBOR.BPM_ART_RPT_ACCOUNT_BALANCE", line 12 ORA-06512: at line 1
Any ideas ?
Thanks

Note that ResultSetConverter.convert(java.sql.ResultSet, java.lang.String, java.lang.String) returns a java.sql.Array. I don't know what BALANCE is (you left out its definition), but it appears to be a single object (i.e. a java.sql.Struct), which is wrong. The purpose of the ResultSetConverter API is to convert a Ref Cursor into something the adapter can handle (i.e. a java.sql.Array), which you may then use to process the array elements.

Oracle function and query return different results

Hi, I am using oracle 10g database.
Function is :
create or replace FUNCTION FUNC_FAAL(myCode number,firstDate date
*, secondDate date)*
RETURN INTEGER as
rtr integer;
BEGIN
select count() into rtr*
from myschema.my_table tbl where tbl.myDateColumn between firstDate and
secondDate and tbl.kkct is null and tbl.myNumberColumn = myCode ;
return (rtr);
END FUNC_FAAL;
This function returns 117177 as result.
But if I run same query in the function seperately ;
select count()*
from myschema.my_table tbl
where tbl.myDateColumn between firstDate and secondDate
and tbl.kkct is null and tbl.myNumberColumn = myCode ;
I get different result 11344 (which is the right one).
Table and function are in the same schema.
What can be the problem ?
Thanks.

1. i think ur parameter name and Column names are same Firstdate and seconddate try to choose different name
2. try using Trunc function around your dates
where trunc(tbl.myDateColumn) between trunc(firstDate) and trunc(secondDate)then compare the result....sometimes time elements comes into play.

Boolean return type. Help please.

i can't figure whats wrong with my isPositive method. It cant display the "true" or "false" after cheking if my nVal is positve or negative.
import java.util.*;
public class Digits
    public boolean isPositive(int nVal)
         if(nVal>=0)
              return true;
         else
              return false;
      public static void main(String[] args)
         int nVal;
         Digits d = new Digits();
         Scanner a = new Scanner(System.in);
         System.out.print("Enter Integer: ");
         nVal = a.nextInt();
         d.isPositive(nVal);
}

Well, you're not doing anything with the return value. Try
import java.util.*;
public class Digits
    public boolean isPositive(int nVal)
         return nVal>=0; // note this simplification, too
      public static void main(String[] args)
         int nVal;
         Digits d = new Digits();
         Scanner a = new Scanner(System.in);
         System.out.print("Enter Integer: ");
         nVal = a.nextInt();
         System.out.println(d.isPositive(nVal));
}

What is the parameter signature for DBMS_OUTPUT.put_line() ?
Is is string - as detailed in Oracle® Database PL/SQL Packages and Types Reference guide.
So how can you pass a boolean data type as parameter value, when the parameter's data type is string?
PL/SQL supports implicit data conversion. So you can for example pass a number or date value to DBMS_OUTPUT.put_line() - and the PL/SQL engine automatically (and implicitly) converts that (using the TO_CHAR() functions) to a string.
However, the TO_CHAR() parameter signature supports number and date - not boolean. It cannot convert a boolean value into a string.
So passing a boolean value means the implicit conversion fails - and results in the above error.
To make it work, you need to perform an explicit conversion. As as a data type conversion function from boolean to string is not available, you need to write a user defined function. E.g.
SQL> create or replace function BoolToChar( b boolean ) return varchar2 is
2 begin
3    case
4       when b then return( 'TRUE' );
5       when not b then return( 'FALSE' );

Use of boolean returning functions in a project

Hello all gurus,
in my project, we have a fairly important packaged functions that return boolean values. Working with these ones in pl/sql is very fine. But sometimes we need to reuse these functions in SQL, but no luck because bools are usable under pl/sql only and can't interact in any way in SQL statements. So the workaround should be to use these functions to return us some Y/N or 1/0 to emulate boolean behavior in SQL statements.
Here what i tested with not luck:
-- not work
select r.role, sys.diutil.bool_to_int(dbms_session.is_role_enabled(r.role)) as is_role_enabled
from   dba_roles r;
-- not work
select r.role
from   dba_roles r
where sys.diutil.bool_to_int(dbms_session.is_role_enabled(r.role)) = 1;
-- not work
select t1.id,
       bool_to_char(my_bool_func(t1.x, t1.y, ...)) as is_something
from   t1;
-- not work
select t1.id,
       sys.diutil.bool_to_int(my_bool_func(t1.x, t1.y, ...)) as is_something
from   t1;The odd wrapping trick as a last resort solution is working....
-- Works! Seems the only way, but a lot of wrapping work...
create or replace function my_bool_func_wrap(p_x number, p_y number, ...) return varchar2 as
begin
   return bool_to_char(my_bool_func(p_x, p_y, ...));
end;
select t1.id,
       my_bool_func_wrap((t1.x, t1.y, ...)) as is_something
from   t1;I read a lot, but no elegant and working way.
Is there a more standard, elegant universal way to call bool functions from SQL?
Is creating a custom type visible and usable from both pl/sql and sql, if possible, a way to go?
Any other pointers?
For new development, is it good to make my boolean type returning functions using SQL compatible type like CHAR (Y/N) or NUMBER (1/0) ? It will make us less wrapping job, but more and less elegant bool handling code on the pl/sql side.
What is the goal to have bool only in pl/sql and not usable in SQL? It's kind of a feature incompatibility in the same product. Strange...
Thanks a lot

Finally, I'll have to dump the BOOLEAN return type to all our boolean functions and return char instead. With this I will be able to call then from SQL.... From this perspective, BOOLEAN is useless.I would not say that. Let's assume that you implement boolean in SQL as a single byte character string containing either Y or N, enforce that with a constraint and also add a not-null constraint to it.
You simply define two PL functions (not usable from SQL) that deals with the conversion. You use the one function to change boolean to char before hitting the SQL engine, and the other to convert char to boolean when getting data from the SQL engine.
As I/O routines are modularised, it means that you need to deal with these conversions once only when writing and once only when reading (per module).
Simple example:

Problem calling Oracle function from Access 2007 / ADO

Hopefully, I'm posting this in the correct forum. I'm also posting on an Access forum as I'm not entirely sure where the issue lies.
I'm calling an Oracle function from Access 2007 using an ADO Command object.
The function takes three input parameters and has a return value and an output parameter. The output parameter is a BLOB, and the return value is varchar2 (either "T" or "N") based on the outcome of the function.
If I pass correct values to the function, I get the following error message (errs out on the command.execute line):

Set Param2 = CMD.CreateParameter("P_INVENTORY_ITEM_ID", adInteger, adParamInput, 4, 5207)
CMD.Parameters.Append Param2
Set Param3 = CMD.CreateParameter("P_REVISION", adVarChar, adParamInput, 2, "04")
CMD.Parameters.Append Param3
Set ParamBlob = CMD.CreateParameter("X_DRAWING", adLongVarBinary, adParamOutput, 200000)
CMD.Parameters.Append ParamBlob
CMD.Execute , , adExecuteNoRecords *** this is where the error occurs
conn.Close
MsgBox CMD.Parameters("RESULT")
End Sub
I've tried using different data types for the varchar2 parameters (adVarChar, adBSTR, adChar) with no difference.
If I pass a bogus value for Param3...."'04'"...the function returns "N" indicating that it actually executed something. But, when I pass the correct value "04", it returns the above mentioned error.
I can execute the function in PL/SQL just fine, so I'm thinking there's something wrong with the parameters, datatype, or other definitions on the Access side.
Does anyone have any thoughts? I'm at a dead end with this. Sorry for the long post. Thank you.

I tried your code with 11107 ODBC/client/database (but with a NULL output blob for convenience sake) and got no errors.
If you're using 92 ODBC/client, you may want to try upgrading to something more current, or at least getting the latest patch(9208) to see if that helps. Since it works for me I'm guessing it may be a resolved bug in that version.
Hope it helps,
Greg
