Call Oracle function using PI

Can we call a Oracle function using PI? If yes then what should be the structure i.e. shoule that be built like a select ? or SQL_DML or ? Stored Procudure ?
Sample structure with example will help

Sure, is possible. You can use an JDBC Adapter (receiver or sender type).
Take a look here:
JDBC ADAPTER

The option to use is an your chose, in according to your requirement.
Usually, I use a StoredProcedure, except for very simple requirements.

Does it work if you add the return parameter first?

Ora-06502 while calling oracle function

I am using 9.2.0.4.0 database.
I have vb.net application that uses oracle provider for .net to connect to database.
I am calling Oracle function which returns varchar2 value back.
when i execute cmd2.ExecuteNonQuery, I get ora-06502 error.
CREATE OR REPLACE FUNCTION ZZZ_TEMP( p_val IN VARCHAR2) RETURN varchar2
AS
BEGIN
RETURN 'HELLO';
EXCEPTION WHEN OTHERS THEN
RETURN SQLCODE||' - '||SUBSTR(SQLERRM,1,100);
END;
************** vb.net code
Dim cmd2 As New Oracle.DataAccess.Client.OracleCommand(UserSchemaName & ".ZZZ_TEMP", con)
Dim VAL As String
Try
cmd2.Parameters.Add("RetVal", Oracle.DataAccess.Client.OracleDbType.Varchar2, ParameterDirection.ReturnValue)
cmd2.Parameters.Add("p_val", Oracle.DataAccess.Client.OracleDbType.Varchar2, ParameterDirection.Input).Value = "XYZ"
cmd2.Connection = con
cmd2.CommandType = CommandType.StoredProcedure
cmd2.ExecuteNonQuery()
VAL = cmd2.Parameters("RetVal").Value
Catch ex As Oracle.DataAccess.Client.OracleException
MsgBox(ex.Message)
End Try

If I change this function to retrun number rather than Varchar2 and change my
RetVal parameter as follow it works. I am noticing that there might be a bug when function returns varchar2
cmd2.Parameters.Add("RetVal", Oracle.DataAccess.Client.OracleDbType.int32, ParameterDirection.ReturnValue)
cmd2.Parameters.Add("p_Val", Oracle.DataAccess.Client.OracleDbType.int32, ParameterDirection.Input).valu ="XYZ"

BPEL Calling Oracle Function

Hi
I have a simple oracle function
create or replace function doubleme(x in integer) return integer as
begin
return x*x;
end;
i am calling this function using DBAdapter in BPEL project. I am not able to get the return value from function. Its throwing timeout exception and when i see the process the return value is null. Please let me know if i am missing anything.

I think you're going to have to use it as a string and use string comparison.

Can I call a function using array index?

I've defined an array which stores the function name, like this:
var aresetButtonTop:Array = new Array(resetTop1,resetTop2,resetTop3,resetTop4,resetTop5);
Then I have a button named"btnresetTop" which when clicked will call one of the five functions stored in the above array(aresetButtonTop). The functions are called at run-time depending upon some conditions. I need to figure out how I can call those functions using the array index. I'm using the following code to call the function. The value of i has been already calculated.
btnresetTop.addEventListener(MouseEvent.CLICK, aresetButtonTop[i]);
After doing this I'm getting the following error when I click the button:
TypeError: Error #2007: Parameter listener must be non-null.
    at flash.events::EventDispatcher/addEventListener()
    at gallerytest_fla::MainTimeline/thumbTopClick()
Note: thumbTopClick() is a function inside which all these codes are written.
I need to find out whether it is posible in AS3 to call a function name using the array index or not. If yes, could you pleas ehelp me out.

Thanx Andrei1, you were right, i was out of range.The value of i will obviously expire outside the for loop. Now I have corrected my mistake by assigning the value of i to a variable index inside the for loop and then use the following code:
btnresetTop.addEventListener(MouseEvent.CLICK, aresetButtonTop[index])
It was a silly mistake but I was not able to figure it out for the last 2 hours. Thanks once again for your help

Calling Oracle function and Procedure using OCCI with in C++ code

Could any body send me the sample code to create and execute Oracle function and Procedure using OCCI concept in C++?.
Edited by: 788634 on Aug 16, 2010 4:09 AM

Hi Vishnu,
Yes, sure, you can create a PL/SQL procedure, function, package, package body, etc. from within an OCCI application. I would say that, generally, this is not the sort of activity a typical client application would perform unless there is some initialization/installation processes that need to happen. In any case, here is a simple demo showing how to create a stand alone procedure (in a real application I would use a package and body) that returns a ref cursor. The ref cursor is just a simple select of two columns in the hr.countries sample table. Of course, there is no error handling, object orientation, etc. in this demo - I wanted to keep the code as short and as simple as possible to illustrate the concept.
Regards,
Mark

Calling oracle function in OMB script

Hi
Can anyone please tell me how can i get the returned value of an oracle function in OMB script. or how can i get the value into OMB variable and use it.
Basically i want to set the properties of OWB mapping via OMB script.
Following OMB code sets the max error limit of a mapping.
OMBALTER MAPPING 'MAP_DATA' SET PROPERTIES (MAXIMUM_NUMBER_OF_ERRORS) VALUES ('100')
i dont want to hard code the value 100 rather i want this value to be returned from a function.
If it is not possible then plz tell me how can i set MAXIMUM_NUMBER_OF_ERRORS property of OWB mapping via sql or pl/sql.
Any type of clue will be highly appreciated.
Best Regards

Here is my bare-bones OMB SQL Library to allow you to do pure SQL calls from within OMB+. All I have ever used it for is to run queries, so I don't have a library procedure for calling a function, however if your function is SQL-callable (e.g. select my_func() from dual) then it would work. Either that or you'll want to augment this library to build a procedure that will call and return the results from a java preparedStatement. It's something I've been meaning to do, but haven't got around to it yet.
All you should need to do is save this as it's own tcl file and then source it at the top of your own script, or embed it into your script.
EDIT: Here is a page with some sample code on using java.sql.CallableStatement to call a Pl/SQL procedure from Java which should certainly do the trick for you in conjunction with the basic session control in my library.

How to call oracle function from ejb3

i'm trying to call an oracle query-function from ejb3.
The oracle function:
create or replace FUNCTION getSecThreadCount(secId in NUMBER,avai in NUMBER)
RETURN SYS_REFCURSOR is cur SYS_REFCURSOR;
m_sql VARCHAR2(250);
BEGIN
m_sql:='select count(thrId) from thread where secId='|| secid||'
and thrAvai='|| avai;
open cur for m_sql;
return cur;
END;
I'v tried several ways to call it,but all failed:
1. the calling code:
public Object getSectionThreadCount(int secId,int avai){
          Query query=manager.createNativeQuery("{call getSecThreadCount(?,?) }");
          query.setParameter(1, secId);
          query.setParameter(2, avai);
          return query.getSingleResult();
but i got the exception:
Exception in thread "main" javax.ejb.EJBException: javax.persistence.PersistenceException: org.hibernate.exception.SQLGrammarException: could not execute query; nested exception is: javax.persistence.PersistenceException: org.hibernate.exception.SQLGrammarException: could not execute query

PLS-00221: 'GETSECTHREADCOUNT' not procedure or not defined
ORA-06550: row 1, col 7:

2. the calling code:
@SqlResultSetMapping(name = "getSecThreadCount_Mapping")
@NamedNativeQuery(name = "getSecThreadCount",
query = "{?=call getSecThreadCount(:secId,:avai)}",
resultSetMapping = "getSecThreadCount_Mapping",

          @QueryHint(name = "org.hibernate.readOnly", value = "true")})
public Object getSectionThreadCount(int secId,int avai){
          Query query=manager.createNamedQuery("getSecThreadCount");
          query.setParameter("secId", secId);
          query.setParameter("avai", avai);
          return query.getSingleResult();
but i run into the exception:
Exception in thread "main" javax.ejb.EJBException: javax.persistence.PersistenceException: org.hibernate.exception.SQLGrammarException: could not execute query; nested exception is: javax.persistence.PersistenceException: org.hibernate.exception.SQLGrammarException: could not execute query

Caused by: java.sql.SQLException: lost in index IN or OUT parameter:: 3
By the way, i have successfully called the function from hibernate. And i use oracle 11g, JBoss5 RC1.
Could anyone tell me how to call the function from EJB3?
Thanks.

}Basically you just ignore the refcursor outbound parameter.
This is a stored function, have yet to try outbound refcursor parameters in stored procedures...

Call Oracle Function from ASP++++!

I have a lot of Oracle function in packages and i would like use it in my ASP pages.
With Oracle procedure it's all right.
Sample like this
set cn = Server.CreateObject("ADODB.Connection")
connString = "Provider=MSDAORA.1;Data Source=<>;User ID=<>;Password=<>"
cn.Open connString
SQL = "{call test.test_asp({resultset 0, cResult})}"
Set cmd = Server.CreateObject ("ADODB.Command")
Set cmd.ActiveConnection = cn
cmd.CommandText = SQL
cmd.CommandType = 1 'adCmdText
Set rs = Server.CreateObject ("ADODB.RecordSet")
Set rs = cmd.Execute
If NOT (rs.BOF and rs.EOF) Then
Do while NOT rs.EOF
<%=rs("dfcountry")%>
<%=rs("dfname")%>
rs.MoveNext
LOOP
End if
And in package TEST i have
PROCEDURE TEST_ASP(cResult IN OUT ResultCursor)
IS
BEGIN
OPEN cResult FOR
SELECT *
FROM tcountry;
END TEST_ASP;"
I Hope You help me with similar call a function!!!
For example, this is one
FUNCTION test_fun
RETURN resultcursor
IS
vres resultcursor;
BEGIN
OPEN vres FOR
SELECT *
FROM tcountry;
RETURN vres;
END test_fun;

Stored Procedures
When executing an Oracle PL/SQL stored procedure using a command, use Oracle native syntax or the ODBC procedure call escape sequence in the command text:
Oracle native syntax: BEGIN credit_account(123, 40); END;
ODBC syntax: {CALL credit_account(123, 40)}
Preparing Commands
OraOLEDB validates and fetches the metadata only for SELECT SQL statements.
Command Parameters
When using Oracle ANSI SQL, parameters in the command text are preceded by a colon. In ODBC SQL, parameters are indicated by a question mark ("?").
OraOLEDB supports input, output, and input/output parameters for PL/SQL stored procedures and stored functions. OraOLEDB supports input parameters for SQL statements.

Calling Oracle Functions and Procedures in Java

I've looked online for a blurb on using Oracle SQL functions and
procedures in Java, but I haven't found anything. Can someone
either give me a quick crash course on this, or point me to the
best source of information for this?

From the SQLJ FAQ.
http://otn.oracle.com/tech/java/sqlj_jdbc/htdocs/faq.html#sqljplsql
Within your SQLJ statements, you can use PL/SQL anonymous blocks
and call PL/SQL stored procedures and stored functions, as in the
following examples: Anonymous
block:
#sql {
DECLARE
n NUMBER;
BEGIN
n := 1;
WHILE n <= 100 LOOP
INSERT INTO emp (empno) VALUES(2000 +
n);
n := n + 1;
END LOOP;
END
Stored procedure call (returns the maximum
deadline as an output parameter into an output host expression):
#sql { CALL MAX_DEADLINE(:out maxDeadline) };
Stored function call (returns the maximum
deadline as a function return into a result expression):
#sql maxDeadline = { VALUES(GET_MAX_DEADLINE)
Of course, you can also use JDBC code to achieve the same - the
standard JDBC escape sequences for stored function and procedure
calls are supported, using for example:
"{? = CALL GET_MAX_DEADLINE}"
or:
"{call MAX_DEADLINE(?)}"
and for the rest of the details, get that JDBC crash course...

Calling oracle function from Access passthrough query does not return list

Thanks to the help I received in an earlier post I've created an oracle 10g function that returns a list after executing the sql it contains. It works in oracle, using sql developer.
I need to have the list that it returns show up in MS Access via a passthrough query. It's not working so far. The connection string etc is ok, I'm able to use passthrough queries to run sql strings successfully. But when I try to call the function via the Access passthrough query at first nothing seems to happen (ie no list appears) and if I try to run it again, there is a odbc error 'call in progress. Current operation canceled'. There are only the three records in the table. I'm missing something, can anyone spot it?
The passthrough query looks like this
select * from fn_testvalues from dual
Again that runs in oracle.
To create the testing table and 2 functions see below.
CREATE TABLE t_values (MyValue varchar2(10));
Table created
INSERT INTO t_values (
SELECT 'Merced' c1 FROM dual UNION ALL
SELECT 'Pixie' FROM dual UNION ALL
SELECT '452' FROM dual);
3 rows inserted
CREATE OR REPLACE FUNCTION fn_isnum(p_val VARCHAR2) RETURN NUMBER IS
n_val NUMBER;
BEGIN
n_val := to_number(p_val);
RETURN 1;
EXCEPTION
WHEN OTHERS THEN
RETURN 0;
END;
Function created
testing the table:
SELECT val, fn_isnum(MyValue ) isnum
FROM t_values;
VAL ISNUM
Merced 0

Now the function that is called in the passthrough query:
create or replace function fn_testvalues
return sys_refcursor is
rc sys_refcursor;
begin
open rc for
Select t_values.*, fn_isnum(MyValue) IsNum from t_values;
return(rc);
end fn_testvalues;

Calling Oracle Function in PHP

Hi,
I'm calling a oracle function in php, the function has 1 IN parameter and 1 OUT parameter. The OUT parameter is BOOLEAN type.How to bind php variable for BOOLEAN type?
Thanks.
srinath.

I think you're going to have to use it as a string and use string comparison.

Toplink JPA Calling Oracle Function Return sys_refcursor

I have a function which return sys_refcursor and I am trying to call this using JPA(1.0)
@NamedNativeQuery( name = "getEmpsByDeptId"
        , query = "{ ? = call my_pck.getEmployees(:longName)}"
        , resultClass = Employee.class
        , hints = { @QueryHint(name = "org.hibernate.callable", value = "true")
                       , @QueryHint(name = "org.hibernate.readOnly", value = "true")
DAOImpl
query = getEntityManager().createNamedQuery("getEmpsByDeptId");
query.setParameter("longName", "SCOTT");
list = (List<Employee>)query.getResultList();
However when I execute, I am getting the following exception
Exception [TOPLINK-6132] (Oracle TopLink Essentials - 2.1 (Build b52-fcs (09/24/2008))):
oracle.toplink.essentials.exceptions.QueryException Exception Description:
Query argument 2 not found in list of parameters provided during query execution.
Query: ReadAllQuery(test.entity.Employee) at oracle.toplink.essentials.exceptions.QueryException.namedArgumentNotFoundInQueryParameters
I have tried using
call my_pck.getEmployees(?)}"
and
query.setParameter(1, "SCOTT");
However error remains the same and how can I resolve this issue?
I have used the same function with Hibernate using JPA2.0 and it has worked.
Thank

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):
Run-time error '-2147467259 (80004005)':
[Oracle][ODBC][Ora]ORA-06502: PL/SQL: numeric or value error
ORA-06512: at line 1
Here's the function:
FUNCTION GET_ITEMREV_ATTACH(P_ORGANIZATION_ID IN NUMBER,
P_INVENTORY_ITEM_ID IN NUMBER,
P_REVISION IN VARCHAR2,
X_DRAWING OUT BLOB) RETURN VARCHAR2 IS
RESULT VARCHAR2(1);
BEGIN
RESULT := 'T';
BEGIN
SELECT L.FILE_DATA
INTO X_DRAWING
FROM FND_ATTACHED_DOCUMENTS AD,
MTL_ITEM_REVISIONS_B IR,
FND_DOCUMENTS_TL D,
FND_LOBS L
WHERE AD.ENTITY_NAME = 'MTL_ITEM_REVISIONS' AND
AD.PK1_VALUE = IR.ORGANIZATION_ID AND
AD.PK2_VALUE = IR.INVENTORY_ITEM_ID AND
AD.PK3_VALUE = IR.REVISION_ID AND
AD.CATEGORY_ID = 1001216 AND
D.DOCUMENT_ID = AD.DOCUMENT_ID AND
D.LANGUAGE = 'US' AND
L.FILE_ID = D.MEDIA_ID AND
IR.ORGANIZATION_ID = P_ORGANIZATION_ID AND
IR.INVENTORY_ITEM_ID = P_INVENTORY_ITEM_ID AND
IR.REVISION = P_REVISION;
EXCEPTION
WHEN OTHERS THEN
RESULT := 'N';
END;
RETURN(RESULT);
END GET_ITEMREV_ATTACH;
Here's the VB code I'm using to call the function:
Private Sub Command8_Click()
Dim CMD As New ADODB.Command
Dim conn As ADODB.Connection
Dim Param1 As ADODB.Parameter
Dim Param2 As ADODB.Parameter
Dim Param3 As ADODB.Parameter
Dim ParamBlob As ADODB.Parameter
Dim ParamReturn As ADODB.Parameter
Set conn = New ADODB.Connection
With conn
.ConnectionString = "Driver={Oracle in OraHome92};Dbq=OAPLY;UID=***;PWD=*******"
.CursorLocation = adUseClient
.Open
End With
Set CMD = New ADODB.Command
Set CMD.ActiveConnection = conn
CMD.CommandText = "immi_attach_pub.get_itemrev_attach"
CMD.CommandType = adCmdStoredProc
Set ParamReturn = CMD.CreateParameter("RESULT", adVarChar, adParamReturnValue, 1)
CMD.Parameters.Append ParamReturn
Set Param1 = CMD.CreateParameter("P_ORGANIZATION_ID", adInteger, adParamInput, 1, 6)
CMD.Parameters.Append Param1
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
