Oracle stored functions and where clauses

Hello everybody,
I need to call an Oracle stored function and at the same time do a select on
the result of the query, it works well except when I use a where clause. I
am connecting to Oracle 8.1.7 through OLEDB using the Oracle provider for
OLEDB distributed with this Oracle version.
Here is the query I am doing:
select * from {call MC.SEC.QryTermbases(?, ?) where ID = ?}
If I remove the where clause it works well but I need to use the where. I
know that I could pass the parameter to the procedure instead of doing that
in the select but there are places where I can not do that since the SQL
query is generated dynamically. The code above is just a demo.
Thanks very much for your help,
Jose.

Thanks for answering, it is actually possible to do a select on the return of a function, I have tested it with other than "select *" and it has worked well. What has not worked for me is using a "where" clause. That is "select" without "where" has worked but not with the "where".
I also suspect that it does not work but similar queries work well in MSSQL 2000 and Interbase 6.0 so I thought may be there was a way to do that with Oracle. That is in MSSQL I can treat the result of a function as a normal table and I can do the same thing with a stored procedure that returns a recordset in Interbase.
Thanks again for answering,
Jose.

Calling a stored function in Oracle 8.1.5 which has out parameters

Hi,
The issue is, I am unable to call or execute a Oracle8.1.5 stored function which has 1 return value and 1 out parameter from neither from .NET nor from VB6.
If I use MSDAORA.1 : wrong number or types of arguments in call to function displays even though everything is perfect.
If i use OraOLEDB.Oracle.1 provider (even though my client and server are 8.1.5,i used this) it says Provider cannot be found. It may not be properly installed. as it is not 8.1.7 or higher. I want to use 8.1.5 only. Kindly give me a solution for this.
If i use 8.1.7 client for the server 8.1.5 my stored function is executing and returning the out parameter perfectly in .NET using MSDAORA.1. But I have to use 8.1.5 client and servers only. Please Help me.
Thanks a lot in advance

Functions normally have only 'in' parameters and return a single out value. Writing a function with an out parameter is risky, at best.
Rewrite the function, and make it a procedure instead. Then I would bet the problem will no longer exist.

Oracle stored function

Does anybody know how to call Oracle stored function from asp

How can i return a SDO_GEOMETRY value in a Java-Stored-Function?

For a example, Ive got a java-function witch returns a
oracle.sdoapi.geom.Geometry like:
public static Geometry GetQPoint(String sF_TABLE_NAME, long lFID)
And now, Ill try to deploy this function as a PL-SQL stored-function like:
GET_Q_POINT(
F_TABLE_NAME IN VARCHAR2,
FID IN NUMBER
) RETURN MDSYS.SDO_GEOMETRY;
I can't deploy this above mentioned java-function with Oracle9i JDeveloper because oracle.sdoapi.geom.Geometry can not mapped in any PL-SQL data type.
Is there any possibility to do it in a other way?
Please help me.

a quick example that takes as input a longitude and latitude,
and return a point geometry in wgs 84:
CREATE OR REPLACE FUNCTION get_geom (
     longitude IN          NUMBER,
     latitude     IN          NUMBER )
     RETURN mdsys.sdo_geometry
     DETERMINISTIC IS
     BEGIN
RETURN mdsys.sdo_geometry (2001,8307,
          mdsys.sdo_point_type (longitude, latitude, NULL), NULL, NULL );
END;

Calling Stored Function from Excel

Folks,
Can someone help me with an Excel Macro that will call an Oracle stored function taking in parameter from one of the Excel Cell and return the value from the function into a different cell in the spreadsheet?
Thanks

This is not the right Forum for this query still here is something for you to start with
The oracle function to add 1 to the input parameter
create or replace function AddOne(ID Number) return number is
Numout Number:=0;
begin
numout:=id+1;
return numout;
end;
The Macro in Excel file to run the above function(Please add necessary references for ado connectivity)
Option Explicit
Dim Objconn As ADODB.Connection

Calling Stored Function from TopLink

I have a simple Stored Function that I'm trying to call using TopLink API:
TopLink Version: 10.1.3.3.
Oracle JDBC Driver: ojdbc5.jar (Oracle JDBC Driver version - "11.1.0.6.0-Production+")
Stored Procedure:
Function Get_Email_Address_Id(P_EMAIL_ADDRESS IN varchar2) return number;
TopLink Code:
public String executeStoredFunction() {
TopLinkTemplate tlTemplate = getTopLinkTemplate();
StoredFunctionCall call = new StoredFunctionCall();
call.setProcedureName("EMAIL_ADDRESS_PKG.Get_Email_Address_Id");
call.setResult("FUNCTION_RESULT", String.class);
call.addNamedArgument("P_EMAIL_ADDRESS");
ValueReadQuery query = new ValueReadQuery();
query.setCall(call);
query.addArgument("P_EMAIL_ADDRESS");
Vector parameters = new Vector();
parameters.addElement("1009");
String result = (String)tlTemplate.executeQuery(query, parameters.toArray());
return result;
Error I'm getting:

Observations:
Why is TopLink complaining about DatabasePlatform?
I'm using Oracle 10g as my database platform. Did anyone encounter this problem?
I have tried various combinations but it always have same complaint.
Thanks in advance for help.

Hello,
It is complaining because the DatabasePlatform being used doesn't support functions. So the problem is that it is using the DatabasePlatform instead of the Oracle10Platform that you are expecting. How have you defined it? Could you have multiple sessions.xml files, and the one that is being picked not define the Oracle10Platform? Or could you be overriding the login somehow (prelogin event etc) and setting it to use the default DatabasePlatform by accident?
Best Regards,

Stored function not returning result set unless recompiled

Hi,
I have a strange situation going on with a basic Java (1.6.0.17) application talking to an Oracle 11g (11.2.0.1.0) database. Basically what is happening is that sometimes a stored function's return value (a result set) is not making it as far as JDBC/Java, unless I recompile the stored function (with absolutely no changes to the application or function's code). I am always able to successfully see the result set if I call the function directly from within SQL Developer, just not on the Java app/JDBC side.
I've tried running with 3 different physical Oracle 11g servers and tried running the app on a couple of machines. I'm wondering if this is either some kind of caching issue or perhaps a JDBC bug/misconfiguration.
Any help would be greatly appreciated. Attached to this message:
1. stored function code
2. snippet of Java app code
3. ODBC trace output when returned a empty result set (ie failure scenario)
4. ODBC trace out when returned the correct result set (ie success scenario)

Wrong value in java stored function

Hi All,
i have written a java stored function,
at the end of the code it insert record into the database
among other columns also a number(18,3) column,
when I debug it (out side of server) - works fine.
when I load it to database i get wrong values in column
(like instead of 76.546 i get 77.667) I can't figure out where it comes from.
I use big decimal in java code.
if i Hard code the value in java code it works fine!
am I missing something ?, calculations/ data type different out side then inside database? using oracle 10.2.0.2
Cheers
Sahar

Hi
the code calculate some averages of amounts ( money) according to several
conditions,and parameters given to the function and stores the average into table in the database
the money columns are of data type 18,3 , both source and target tables have same structure.
thanks
Sahar

Cannot call ANY stored functions from my Java program

My problem is that I cannot call ANY stored procedure from my Java
program. Here is the code for one of my stored procedures which runs
very well in PL/SQL:
PL/SQL code:
CREATE OR REPLACE PACKAGE types AS
TYPE cursorType IS REF CURSOR;
END;
CREATE OR REPLACE FUNCTION list_recs (id IN NUMBER)
RETURN types.cursorType IS tracks_cursor types.cursorType;
BEGIN
OPEN tracks_cursor FOR
SELECT * FROM accounts1
WHERE id = row_number;
RETURN tracks_cursor;
END;
variable c refcursor
exec :c := list_recs(11)
SQL> print c
COLUMN1 A1 ROW_NUMBER
rec_11 jacob 11
rec_12 jacob 11
rec_13 jacob 11
rec_14 jacob 11
rec_15 jacob 11
Here is my Java code:
import java.sql.*;
import java.io.*;
import oracle.jdbc.driver.*;
class list_recs
public static void main(String args[]) throws SQLException,
IOException
String query;
CallableStatement cstmt = null;
ResultSet cursor;
// input parameters for the stored function
String user_name = "jacob";
// user name and password
String user = "jnikom";
String pass = "jnikom";
DriverManager.registerDriver(new oracle.jdbc.OracleDriver());
try { Class.forName ("oracle.jdbc.driver.OracleDriver"); }
catch (ClassNotFoundException e)
{ System.out.println("Could not load driver"); }
Connection conn =
DriverManager.getConnection (
"jdbc:oracle:thin:@10.52.0.25:1521:bosdev",user,pass);
try
String sql = "{ ? = call list_recs(?) }";
cstmt = conn.prepareCall(sql);
// Use OracleTypes.CURSOR as the OUT parameter type
cstmt.registerOutParameter(1, OracleTypes.CURSOR);
String id = "11";
cstmt.setInt(2, Integer.parseInt(id));
// Execute the function and get the return object from the call
cstmt.executeQuery();
ResultSet rset = (ResultSet) cstmt.getObject(1);
while (rset.next())
System.out.print(rset.getString(1) + " ");
System.out.print(rset.getString(2) + " ");
System.out.println(rset.getString(3) + " ");
catch (SQLException e)
System.out.println("Could not call stored function");
e.printStackTrace();
return;
finally
cstmt.close();
conn.close();
System.out.println("Stored function was called");
Here is how I run it, using Win2K and Oracle9 on Solaris:
C:\Jacob\Work\Java\Test\Vaultus\Oracle9i\FunctionReturnsResultset>java

Any help is greatly appreciated,
Jacob Nikom

Thank you for your suggestion.
I tried it, but got the same result. I think the difference in the syntax is due to the Oracle versus SQL92 standard
conformance. Your statament is the Oracle version and mine is the SQL92. I think both statements are acceptable
by the Oracle.

Why returning string from java stored function failed ? HELP ME, PLEASE

Hi everybody,
I created java stored function: it's doing http post, parsing xml from http reply, and returning string result.
Sometimes, it doesn't return any value. What can be a reason ?
The high level procedure, has following form:
class SBE {
public static String call(String arg0) {
SBE sbe=new SBE("d:\\oracle\\ora81\\network\\log\\SBE.log");
String result=SBEParser.go(sbe.sendRequest(arg0, ""), sbe.logger);
sbe.logger.log(result);
sbe.logger.log("Finish SBE intetraction");
return result;
PLSQL wrapper has a simple form:
create or replace package PG_SBE as
function CALL(arg0 in varchar2) return varchar2;
end;
create or replace package body PG_SBE as
function CALL(arg0 varchar2) return varchar2 as language java name 'SBE.call(java.lang.String) return java.lang.String';
end;
In log file ("d:\\oracle\\ora81\\network\\log\\SBE.log"), I can find message :
"Finish SBE intetraction"
but query:
select pg_sbe.call("any argument") from dual;
doesn't finish.
What can be a reason ? What can I do to trace stage of convertion java string to varchar ?
Please help me...
Best regards
Marek

hi Stefan thanx.....even after changing the call statement i get the same error. i changed query string as...
String myquery = "{ ? = call jspTest}";
CallableStatement cst = con.prepareCall(myquery);
Can u please check out my call sepc that i have written in pl/sql and plz let me know it there is any error in that.

This comes up periodically. It just isn't possible using that type of approach. Probably the best you could do is the create an ADT (containing collections) and use that to pass a 'batch' of information.
Hopefully this will get addressed in the next release of the database.

Named parameters in stored function

Hi,
I am trying to execute stored function from java in oracle . I am using Oracle 9.2.0.1.0 and the newest JDBC drivers, ie. for 10g which are compatible. I have flicked through JDBC Named Parameters example but it only addresses stored procedures.
The problem I have is that I do not know what name the return value of stored procedure has.
stored function parameter names:
1. ????
2. test1 Mode: IN
3. test2 Mode: IN
?=call test_function(?,?);
When I am trying to set values as indexes everything works perfect.
CallableStatement cs = .....
cs.registerOutParameter(1, Types.VARCHAR);
cs.setString(2, "a");
cs.setString(3, "b");
cs.execute();
String returnedValue = cs.getString(1);
However, when I am trying to use named parameters the code looks like this:
CallableStatement cs = .....
cs.registerOutParameter(1, TYPES.VARCHAR);
cs.setString("test1", "a");
cs.setString("test2", "b");
and the question is what is the name of return parameter.
I have tried to put the same name as the name of stored function but is reports error.
Instead I had to first getmetadata from oracle and in case of stored functions utilize it, unfortunatelly getting metadata has perfomance issues and I heard that oracle 10g is even slower in getting metadata.
If anyone knows the answer to my question, please answer.
