Calling Oracle Functions in Data Template

Hi,
I have a package and 2 functions inside that, I need to use those 2 functions inside my BI Publisher Data Template,
Package1
Function1(Param1 varchar2,param2 varchar2) return Refcursor
Open Refcursor for
Select Fun1Col1,Fun1Col2,Fun1Col3 from ABCD;
Function2(Param1 varchar2 , Fun1Col1 varchar2,Fun1Col2 varchar2 ) return Refcursor
Open Refcursor for
Select Fun2Col1,Fun2Col2,Fun2Col3 from XYZ where XXX=Fun1Col1 and YYY=Fun1Col2 and ZZZ=Param1;
Here the Second Function is using the Output Columns of First Function as Input Parameters.
The above functions are created for Oracle Reports which is working fine, Now I am converting them from Oracle Reports to BI Publisher and I am not able to proceed.
I have designed my Data Template as follows.
<dataTemplate name="XYZ " description="XYZ" defaultPackage="">
     
     <properties>
          <property name="scalable_mode" value="off"/>
          <property name="debug_mode" value="off"/>
     </properties>
     
     <parameters>
          <parameter name="Param1" dataType="varchar2"/>
          <parameter name="Param2" dataType="varchar2"/>
     </parameters>
     
     <lexicals/>
     
     <dataQuery>
          <sqlStatement name="Q_Container_Query">
               <![CDATA[
Select Package1.Function1(:param1,:param2) from dual;
]]>
          </sqlStatement>
          <sqlStatement name="Q_Container_Item_Query">
               <![CDATA[
Select Package1.Function2(:param1,:Fun1Col1,:FunCol2) from dual
]]>
          </sqlStatement>
     </dataQuery>
     
     <dataStructure>
          <group name="G_Container_Query" source="Q_Container_Query">
               <element name="Fun1Col1" value="Fun1Col1"/>
<element name="Fun1Col2" value="Fun1Col2"/>
<element name="Fun1Col3" value="Fun1Col3"/>
               <group name="G_Container_Item_Query" source="Q_Container_Item_Query">
               <element name="Fun2Col1" value="Fun2Col1"/>
<element name="Fun2Col2" value="Fun2Col2"/>
<element name="Fun2Col3" value="Fun2Col3"/>
               </group>
          </group>
     </dataStructure>
</dataTemplate>
The point of concern is whether
Select Package1.Function2(:param1,:Fun1Col1,:FunCol2) from dual
is valid or not, because its accepting Function1's output values as Input Parameters.

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"

I have created data template like following,
<sqlStatement name="Q_INVOICE">

</sqlStatement>
But how does I create a element for the "t1.ship_city || ', ' || t1.ship_state || ' ' || t1.ship_zip" column in the oracle function. I normally create an element like following,
<group name="G_INVOICE" source="Q_INVOICE">
               <element name="CUST_ORDER_NBR" value="cust_order_nbr"/>
               <element name=":dest_id" value="dest_id"/>
</Group>
But how do i create element if a column name is kind of dynamic. Please help. I cannot Rename/change the Column in SQL Query. Please let me know If I could handle this whole logic in BI Publsiher.

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.

Call oracle function in ODI

I am new to ODI. I need to call a function created on the database which return a value. In ODI I created a variable. In the select (of the variable) I don't know how to call the source table value that needs to be passed to the function.
My oracle function:
create or replace function return_timeid(trans_date in date)
return number is
Result number;
v_trans_date varchar2(30) := to_char(trans_date, 'dd-mon-rrrr hh24miss');
v_hour number := 0;
v_min number := 0;
begin
v_hour := substr(v_trans_date, 13, 2);
v_min := substr(v_trans_date, 15, 2);
case
when v_min between 1 and 30 then
result := (v_hour * 100) + 30;
when v_min = 0 then
result := v_hour * 100;
when v_min > 30 then
result := (v_hour + 1) * 100;
end case;
-- convert 2400 to 0000
if result = 2400 then
result := 0;
elsif result = 2430 then
result := 30;
end if;
return result;
end return_timeid;
The result will be a time ID, depending on the source record value in the source table. How do I keep the time ID in the variable that I created.
This is the select in my variable (Time_ID):
SELECT BIUSER.return_timeid(GPRS_HOME_CDRS.CALL_DATE_DT) FROM dual
this is my error:
904 : 42000 : java.sql.SQLException: ORA-00904: "GPRS_HOME_CDRS"."CALL_DATE_DT": invalid identifier
Regards

I tried to call the function in the mapping. My code:
biuser.return_timeid(GPRS_HOME_CDRS.CALL_DATE_DT)
but then I get the ORA-00936 (missing expression)

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:

          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.

Here's a working model:
package.procedure: (created in example schema scott)
CREATE OR REPLACE package body data_pkg as

}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 a package in Data template

Hi All ,
I am using Data template for XML generation and want to call a PL/SQL package.I have gone through some of the threads on the topic.
I have some doubts in this regard :
1)Can we have procedures inside package or its just the functions that can be called.
2)Does the package gets executed every time we generate the report.(It got executed for me just once).
3)The parameters defined in the data tamplte can be passed to the PAckage as well?
4) Is this supported on BIP 10.1.3.2 or XML publisher 5.6.2?
Thanks!!

Thanks for your detailed answer!!
I am trying to call a package just to understand how it works .This package just inserts a row in "suppliers" table.I ma calling this package through 'beforeReprot' trigger and querying the table after that.
I have written a package "test_pack" :
create or replace
package test_pack as
function test_insert_fun return boolean;
end test_pack;
create or replace
package body test_pack as
function test_insert_fun return boolean is
begin
insert into suppliers values (1,'p1','p2');
return (TRUE);
end;
end test_pack;
Data Template :
<dataTemplate name="test" dataSourceRef="demo" defaultpackage="test_pack">
     <dataQuery>
          <sqlStatement name="Q1">
               <![CDATA[SELECT * from suppliers]]>
          </sqlStatement>
     </dataQuery>
     <dataTrigger name="beforeReport" source="test_pack.test_insert_fun()"/>
</dataTemplate>
However after this , when I try to view data , I amnot seeing any output.When i go nad check the suppliers table in db, i dont see any values.
I believe this package should be executed everytime i view the data.
Please advice!!

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
Pixie 0
452 1
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;

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.

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

Calling oracle functions from PreparedStatement

Hi everybody,
I have got the transaction rolled back when I tried to call HexToRaw() function of oracle to insert raw data into a table. The raw data column is of size 30 chars.
Part of my prepared statement is :
" VALUES(?,?,?, HEXTORAW(00000000000000000000000000000000),?,?) "
I just need to insert a sequence of zeroes into the column, so no setBytes() needed i guess.
Any help will be apprciated.
Thank you all.

Could anyone please reply....

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
