Function return type could be sequence?

I tried to write a function return a sequence, but netbeans don't allow it. is it possible? if not, how can I solve it?

Here is an example of a function and a var as a function.
function foo():Integer[] {
[0..9]
var bar:function():Integer[] = foo;
for ( i in bar() ) println("{i}");

Prior, Next, Shift functions return type?

I can not point out what is the return type of these functions? numeric value or member?
And if they return a member would this fomula be valid (i need to take avg value of march and june):
avgppl = @avgrange("HRsummary" -> "territory",@list(@currmbr("YearTotal"),@shift(@currmbr("YearTotal"),-3)))
Thanks in advance!

just use simple arithmetic combined with other functions
e.g.
If you want sum of base time periods underneath a summary time period, and make the formula generic to work on base time periods:
@SUMRANGE(@CURRMBR(Account),@Relative(@CURRMBR(Period),0))/@COUNT(SKIPNONE,@Relative(@CURRMBR(Period),0))
or, instead if you want the quarter averages at base time periods...
@SUMRANGE(@CURRMBR(Account),@Relative(@Relative(@CURRMBR(Period),-1),0))/@COUNT(SKIPNONE,@Relative(@Relative(@CURRMBR(Period),-1),0))

Column Function Return Type Number is forcing to cast to Decimal

Hi - I am using Oracle 11g Release 11.2.0.2.0 and ODP.NET 4.112.3.0.
Whenever I am trying to execute a package query with column function and return type is number, it is throwing cast exception whenever I am trying to cast it as GetInt32.
The workaround we have for now is to get it decimal and cast to Int32, this is going to be painful moving forward because it means that we have to check each of our packages and need to know if each package has column function and do this special casting.
Is this a known bug?

How to PL/SQL Function returns type

Hello,
I need to create a function, which is returning a list of ID's, which is stored in a type T_IDs, something like:
function search(searchstring in varchar2) return T_IDs
I have a little problem with filling the type inside the function body using a select statement like
select id from table where text like searchstring;
which is selecting a list of ids matching the where-clause. Is it possible to use select into or should I go for another mechanism?
Thanks for any ideas.

Function return type

I have a return string from function contains more than 4000 bytes.
But VARCHAR2(4000) is only 4000 bytes.
Is there ay way we can return more than 4000
Thanks a lot for the help
Prasad

You could create a nested table within this function...this nested table can be of type varchar2(4000).
Cut your string into various pieces as elements of this nested table..and you can reconcat yuor string when this function is returned.

Sandy,
I have a series of examples on this issue in my demo application. See this one:
http://htmldb.oracle.com/pls/otn/f?p=31517:146
You will basicaly need to write it like this:
CREATE OR REPLACE TYPE u_voc.t_in_list_tab AS OBJECT (
   i_group     NUMBER,
   i_company   NUMBER,
   i_estab     NUMBER
CREATE OR REPLACE TYPE u_voc.t_in_list_tab_type AS TABLE OF u_voc.t_in_list_tab;
CREATE OR REPLACE FUNCTION fu_voc_s_vehicles (
   pi_group     NUMBER,
   pi_company   NUMBER,
   pi_estab     NUMBER
   RETURN t_in_list_tab PIPELINED
AS
   l_tab   t_in_list_tab := t_in_list_tab (NULL, NULL, NULL);
BEGIN
   FOR c IN (SELECT v_ref_vehicles.nb_idvehicle, v_ref_vehicles.vc_reference,
                    v_ref_vehicles.vc_licenceplate
               FROM u_ref.v_ref_vehicles
              WHERE v_ref_vehicles.nb_idgroup = pi_group
                AND v_ref_vehicles.nb_idcompany = pi_company
                AND v_ref_vehicles.nb_establ = pi_estab)
   LOOP
      l_tab.i_group := c.nb_idvehicle;
      l_tab.i_company_number := c.vc_reference;
      l_tab.estab_number := vc_licenceplate;
   END LOOP;
   RETURN l_tab;
END;
SELECT *
FROM TABLE (fu_voc_s_vehicles (value1, value2, value3))But looking at your code, your function will return only one record.

OracleDbType for function OBJECT return type

Hi all,
I inherited an oracle function that has an object as a return type:
create or replace TYPE OBJECTPATH IS OBJECT (OBJECTID NUMBER);
create or replace TYPE OBJECTPATH_TAB AS TABLE OF OBJECTPATH;
create or replace FUNCTION GETOBJECTINPATH ( pobjectid in NUMBER, role1 varchar2, role2 varchar2 ) RETURN OBJECTPATH_TAB
IS
v_tmp_tab OBJECTPATH_TAB:=OBJECTPATH_TAB();
parentid NUMBER;
rowno INTEGER;
BEGIN
rowno:=0;
parentid:=pobjectid;
loop
select objectid into parentid from dual left join (select ro2.objectid from relationshipobject ro1, relationshipobject ro2
where ro1.role=role1 and ro2.role=role2 and ro1.relationshipid=ro2.relationshipid and ro1.objectid=parentid)
on 1=1;
if parentid is null then
exit;
end if;
v_tmp_tab.extend;
rowno:=rowno1;+
v_tmp_tab(rowno) := OBJECTPATH(parentid);
end loop;
RETURN v_tmp_tab;
END;
On my application side, I am trying to run this function and retrieve the return value with ODP.NET as below. However, I am stumped when I need to supply an OracleDbType for the function return type.
1. What is the OracleDbType I should use for the return type? I read that there used to be support for OracleDbType.Object, but it seems like it is now not supported. I am using ODP.NET 11g. Am I getting the situation correct?
2. If retrieving an object return type is not as straightforward as setting the parameters (as what I have done below), what is the workaround to achieve it?
OracleCommand runGetPObjectInPathCmd = new OracleCommand("GETOBJECTINPATH", conn);
runGetPObjectInPathCmd.CommandType = CommandType.StoredProcedure;
runGetPObjectInPathCmd.Parameters.Add(new OracleParameter("pobjectid", OracleDbType.Decimal)).Value = pobjectId;
runGetPObjectInPathCmd.Parameters["pobjectid"].Direction = ParameterDirection.Input;
runGetPObjectInPathCmd.Parameters.Add(new OracleParameter("role1", OracleDbType.Varchar2, 255)).Value = role1;
runGetPObjectInPathCmd.Parameters["role1"].Direction = ParameterDirection.Input;
runGetPObjectInPathCmd.Parameters.Add(new OracleParameter("role2", OracleDbType.Varchar2, 255)).Value = role2;
runGetPObjectInPathCmd.Parameters["role2"].Direction = ParameterDirection.Input;
runGetPObjectInPathCmd.Parameters.Add("OBJECTPATH_TAB", OracleDbType.Decimal); // this is not correct as the return type is not a NUMBER
runGetPObjectInPathCmd.Parameters["OBJECTPATH_TAB"].Direction = ParameterDirection.ReturnValue;
runGetPObjectInPathCmd.ExecuteNonQuery();
Thanks in advance for any help and would greatly appreciate it.

Hi Greg,
Thanks for your reply. I am not exactly sure whether I am using 11.1.0.6.21. The Oracle.DataAccess.dll I see under my \ODP.NET\bin\2.x directory is of Assembly/Product Version 2.111.6.0 - is this version 11.1.0.6.21? I also do not have the samples directory. Am I working on a wrong version? Thanks for your patience as I am really new to this and appreciate your guidance.

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.

DLL return type and parmaters

I must access a DLL developped by VC++ via LV6i with the 'Call Library function'. Everythimg is fine, but the DLL function return type is bool, and I don't find the bool data type in the 'Call library parameter'.
Secondly, I must pass parameters to this DLL function. Parameters type are : std::vector and GUID. How can I pass this type of parameters ??
Function is : bool MyFunction (const GUID &guidMyGuid, std::vector &MyVector).
Thanks in advance.

You can't, you have to create a CIN that reshapes this parameters to something LabView understand.

Problem when calling a return type BOOLEAN SQL Function in a package

Hi All,
I am having problem when trying to call a SQL function in a package with return type BOOLEAN
The SQL function signature is as follows
CREATE OR REPLACE PACKAGE RMSOWNER.ORDER_ATTRIB_SQL ****
FUNCTION GET_PO_TYPE_DESC(O_error_message IN OUT VARCHAR2,
I_PO_TYPE       IN     VARCHAR2,
O_PO_TYPE_DESC IN OUT VARCHAR2)
RETURN BOOLEAN;
Following is my java code
+CallableStatement cs3 = conn.prepareCall("{?=call ORDER_ATTRIB_SQL.GET_PO_TYPE_DESC(?,?,?)}");+
+cs3.registerOutParameter(1, java.sql.Types.BOOLEAN);+
+cs3.registerOutParameter(2, java.sql.Types.VARCHAR);+
+cs3.registerOutParameter(4, java.sql.Types.VARCHAR);+
+cs3.setString(2, "");+
+cs3.setString(3, "ST");+
+cs3.setString(4, "");+
+ResultSet rs3 = cs3.executeQuery();+
I get the following exception, i tried changing the sql type(registerOutParameter) from boolean to bit but i still getting this exception.
But when i call any other functions with return type other than boolean they work perfectly fine.
Please can anyone help me fix this issue, i am not sure if its anything to do with vendor JDBC classes?

As you can see the CallableStatement class acepts PL/SQl blocks.

How to make a function return number(10,0) data type (ORACLE 10g)?

With 10g, how to make a function return number(10,0) data type?
here is the function, it returns a number type :
create or replace FUNCTION Get_portfolio_Id3 (p_HistObjTable In Varchar2,p_LHISTOBJID IN NUMBER) RETURN view_cpu_STD_Asset.LPORTFOLIOITEMID%Type IS
v_Id view_cpu_STD_Asset.LPORTFOLIOITEMID%Type;
BEGIN
If p_HistObjTable ='amPortfolio'
then v_Id:=p_LHISTOBJID ;
elsIf p_HistObjTable = 'amComputer' then
select litemid into v_Id from smcdba.amComputer c where c.LCOMPUTERID=p_LHISTOBJID ;
else v_Id:=-99;
End If;
RETURN v_Id;
END Get_portfolio_Id3;
Thanks.

Can Evaluate function return object type

Hi
Evaluate function can be used to call db functions in OBIEE. I have a function which returns an object ( pl/sql table).
Created a simple report in Oracle Answers and added following in one of the columns
evaluate( 'get_ccid(%1)' as t_ccid , @{p_request})
When I try to run this in Oracle answers, getting syntax error. If same function returns varchar or number it works well.

evaluate( 'get_ccid(%1)' as t_ccid , @{p_request})Eakta, You syntax seems to be wrong here. What type of data your presentation variable contains here ?? You are saying its working fine with Number datatype..so can you try..somthing like below with some default value..
EVALUATE('get_ccid(%1)',@{p_request}{2})
OR
EVALUATE('get_ccid(%1)' as varchar(250),@{p_request}{ABC})
Also, refer
Syntax for Evaluate function in OBIEE

Hope its useful

Function with return type boolean

I have created a function with return type boolean as:
CREATE OR REPLACE FUNCTION fn RETURN BOOLEAN
AS
exp EXCEPTION;
BEGIN
return TRUE;
EXCEPTION
when OTHERS then RAISE exp;
END;
FUNCTION fn compiledThen I was trying to call this function into dbms_output.put_line procedure, I got this error:
EXECUTE DBMS_OUTPUT.PUT_LINE(fn);
ORA-06550: line 1, column 7:
PLS-00306: wrong number or types of arguments in call to 'PUT_LINE'Can someone please help me understand, why this happened?
Is this because of boolean return type?

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' );
6    else
7      return( null );
8    end case;
9 end;

SQL>
SQL> exec DBMS_OUTPUT.put_line( 'Flag is '||BoolToChar(true) );
Flag is TRUE

Return type Boolean From Oracle Function

1. How do I get a return type of Boolean from Oracle function in Java?
2. I have a function fx overloaded in Oracle (8 variances) and I have trouble getting the right one in Java. Is 8 too high a figure or Java does not support calling overloaded functions or what?
Thanks for any help.

I am facing a similar situation, where I have defined an overloaded function in one package (2 variants) which both return a type BOOLAN value.
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( indez, parameter, OracleTypes.BIT );
or
callablestatement.setobject( indez, 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

Function return type could be sequence?
