Call Oracle Function via JDBC Adapter

Hi to everybody,
using JDBC connection with an Oracle DB, from XI I manage to send messages to execute SQL statements or Stored Procedures. Does anybody know if there is a way to call also an Oracle Function?
Thanks a lot for any help...
Ilaria

Hi Illaria,
I think i agree with Michal. The solution to your problem would be to go for a stored procedure. The link on SDN help only tells us that a stored procedure can be executed and does not discuss about oracle functions.
http://help.sap.com/saphelp_nw04/helpdata/en/2e/96fd3f2d14e869e10000000a155106/content.htm
So, Stored Procedures, it has to be.

Oracle Function in JDBC Adapter

Dear All
Can we execute an oracle fucntion using receiver jdbc adapter? if yes then what should be the structure
I have gone through following links but the soluiotn is not clear
Using PI - Calling a Function in Oracle

I think two possible ways. You might want to write stored procedure and inside your stored procedure call oracle function. The second option is as below. In access tag write your query with standard functions. placeholder is to pass values for the variable.
<StatementName>
<anyName action=u201D SQL_QUERYu201D | u201CSQL_DMLu201D>
<access>SQL-String with optional placeholder(s)</access>
<key>
<placeholder1>value1</placeholder1>
<placeholder2>value2<placeholder2>
</key>
</anyName >
</StatementName>
Ex:
SELECT '03.12.2004:10:34:24' "Now",
       TO_CHAR(hiredate,'DD.MM.YYYY:HH24:MI:SS') "Hiredate",
       TO_DATE('03.12.2004:10:34:24','DD.MM.YYYY:HH24:MI:SS')
       - hiredate "Hired since [Days]"
FROM emp;
where to_char is the oracle function.

Calling Oracle function in JDBC

Hi,
The function in Oracle is defined as
FUNCTION SETUP RETURNS BOOLEAN
Argument Name Type In/Out Default?
PI_NE_ID NUMBER IN
PI_PI_AID VARCHAR2 IN
PI_ATTR_NAME_LIST_ID VARCHAR2 IN
PI_NETYPE VARCHAR2 IN DEFAULT
PI_CLLI VARCHAR2 IN DEFAULT
DI_CATEGORY VARCHAR2 IN/OUT
MSG VARCHAR2 IN/OUT
My code in Java is
CallableStatement stmt = con.prepareCall("{? = call ges.
Setup(?,?,?,?,?,?,?)}");
System.out.println( " formed call statement" );
stmt.setInt( 1, 6);
stmt.setString( 2, "COM-5004" );
stmt.setString( 3, "TS35-COM" );
stmt.setString( 4, "*" );
stmt.setString( 5, "*" );
stmt.setString( 6, "C" );
stmt.setString( 7, msg );
stmt.registerOutParameter( 8, Types.BIT );
stmt.registerOutParameter( 6, Types.VARCHAR );
stmt.registerOutParameter( 7, Types.VARCHAR );
stmt.execute();
I have tried commenting registerOutParameter for 6 and 7. But I get the error
Connectingjava.sql.SQLException: ORA-06550: line 1, column 13:
PLS-00382: expression is of wrong type
ORA-06550: line 1, column 7:
PL/SQL: Statement ignored
Can anybody please tell what is the problem.
I am using JDK1.3.
When I give Type.BOOLEAN instead of BIT I get compilation error.
Thanks
Smitha

Hi Smintha,
Oracle does not support the return of Boolean over JDBC. To work around this problem you have to write a wrapper function around your original function which returns then for example a number value that indicates true or false.
I assume that the reason for not returning boolean values is that Oracle's boolean value is threefold it can either be true, false or null where null is neither success or failure but rather non-existing.
Let me know if you need any further examples about this.
Hope this helps,
Kalle

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;

    BEGIN
        FOR v_rec IN testvalues_cur LOOP

        RETURN;
END;

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"

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.

Invoking PL/SQL function (via DB Adapter) with in parameter (BPEL newbie)

create or replace function f_test_bpel (p_in in number)
return number
is
begin
return p_in;
end;

Adding more to what 'Arcturus' has put across :
1) You can check your input & output arguments to a PL/SQL function/procedure using an assign activity, in which you tend to assign a source variable to a target variable.
Here, you can check to see, if the input & output to the DB Adapter are correct, if not, you can always recreate the adapter.
2) You can also check the schema of the PL/SQL function, to check if it has the right inputs & outputs.
It'd be a .xsd file in the format of <SCHEMA_NAME-OF-FUNCTION.xsd> viz. SCOTT_EMPDETAILS.xsd

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

JDBC MESSAGE FORMAT
http://help.sap.com/saphelp_nw04/helpdata/en/2e/96fd3f2d14e869e10000000a155106/content.htm
The option to use is an your chose, in according to your requirement.
Usually, I use a StoredProcedure, except for very simple requirements.

Calling Stored Procedure without JDBC-Adapter

Hallo,
as it is not possible calling Stored Procedures with the parameter Typ Record in Oracle my question: It is possible connecting to DB using native java-code for example in Mapping?
Thanks in advance,
Frank

Hi Frank,
Maybe you can use the DB look up using the JDBC adapter in your mapping.
Just check this blog for the same,
/people/siva.maranani/blog/2005/08/23/lookup146s-in-xi-made-simpler
As for calling an Oracle Strored Procedure, it is possible using a RECEIVER JDBC adapter, but not a SENDER JDBC adapter.
<i> import the jdbc-driver (oracle) in an archive in Designer.</i>
Also, this imported archive should be under any Namespace, but, it should be in the same SWCV as the one in which the mapping is being executed.

Bhavesh

Calling Stored Procedure from JDBC Adapter

Hello,
I am Updating a SQL Server Table using JDBC Adapter.
Now I have multiple input rows and the procedure needs to be called for each set.
Do I need to use multimapping for this or just generating multiple <b>Statement</b> node will solve?
Also For this will there is any knows/ forseen problem (like Transaction handling) that I need to take care of?
Thanks and Regards,

Himadri,
You can just create multiple statement nodes in one message.
I am not aware of any known or foreseen issues with this approach.
