Executing DML-ing stored function from EntityManager

Hi,
Is there some way of getting the result from a DML-ing stored function from the EntityManager? I can use a native query and just select the function from dual if it doesn't do any DML but when it does, it is not permitted. I can't use getDelegate() to get the raw connection either :-/

Calling database stored function from Entity Object

Hi,
I want to call a database stored function from create() method of Entity Object.
Database function returns some value.
Can anybody suggest me some way to do it.

You can try the following:
make a String whit your function call, I dont know if this is the correct SQL syntax for a function, it should be for a stored procedure.
String call = "begin; callyourfunction; end;"
PreparedStatement ps = getDBTransaction().createPreparedStatement(call,0);
ps.execute();
ResultSet rs = ps.getResultSet();
You can now read the data from the function from the rowset.
Be sure to cleanup the PreparedStatement when your done whit it to avoid open database connections.
ps.close();ps=null;

How to execute a HANA stored proc from Data Services

Hi
How do i execute a HANA stored procedure from Data Services.
in the HANA SQL editor , we run the stored procedure "name_of_sp" as
call name_of_sp ();
call name_of_sp ( 1 , 2 ) // suppose 1 and 2 are two integer input parameters.
so how do I call the above from Data Services .
SQL('name_of_datastore', 'call name_of_sp()') does not seem to work , ,
Rishi

I got the answer , we dont need to import sp .
i was just having a syntax error:
the statement below works
SQL('name_of_datastore', 'call name_of_sp()');

Execute a stored function from command line

Hello,
I have a db stored function and I need to execute it from command line. I've tried by this way:
(I need to connect with sys credentials)
sqlplus sys/mypwd@mydb AS SYSDBA @myfile.sql
and myfile.sql is:
exec myschema.sf_test;
but I get this error:
ERROR at line 1:
ORA-06550: line 1, column 7:
PLS-00221: 'sf_test' is not a procedure or is undefined
ORA-06550: line 1, column 7:
PL/SQL: Statement ignored

You can use exec command for the execution of a procedure with out bind variable, but for a function always use bind variable.
Function should return a value, so you must have to assign the function return value to a variable.
like given below(or simply query the function using select statement)
Method 1
======
variable v1 number;
exec :v1 := t_func;
Method 2
======
declare
x1 NUMBER;
begin
x1 := t_func;
end;
SQL> create function t_func return number
2 as
3 begin
4 return 0;
5 end;
6 /
Function created.
SQL> exec t_func;
BEGIN t_func; END;
ERROR at line 1:
ORA-06550: line 1, column 7:
PLS-00221: 'T_FUNC' is not a procedure or is undefined

Method 3

Executing an Oracle Stored Procedure from Sender JDBC adapter

I could really use some help from someone who had done this before.
I've read the help about using the JDBC sender adapter, but it's not helping enough.
I found this line: "Specify an SQL EXECUTE statement to execute a stored procedure, which contains exactly one SELECT statement.
The expression must correspond to the SQL variant supported by the relevant JDBC driver. It can also contain table JOINs."
That's definately what we want to do, but we can't figure out the syntax.
The procedure in oracle looks like this:
CREATE OR REPLACE PROCEDURE test_ref_cursor
( cur_generic IN OUT result_sets.cur_generic)
as
BEGIN
Open cur_generic for
select
   proposal_number,
   to_char(sequence_number),
   column_name,
   column_value,
   update_timestamp,
   update_user
   from
   coeus.sap_test;
END test_ref_cursor;
And we have tried every kind of statement we can think of, but the file adapter always gives us an "invalid sql statement" error.
Does anyone know what syntax we need to put in the "Query SQL Statement" in the JDBC sender adapter in order to call this procedure? Or is there something wrong with the procedure that is causing the error?
<i>I will absolutely return and give points, but PLEASE read my whole post before answering and do not just link me to or quote the help for configuring a sender JDBC adapter or blogs that are about the JDBC adapter in general but do not deal with the issues I am having. Thank you.</i>

Hi Vanda,
Unfortunately, the sender JDBC adapter does not support Oracle's store procedure/function. Unlike stored procedures from other database vendors, Oracle returns a cursor, not a resultset. The sender JDBC adapter must send a resultset to XI.
There are 2 possible ways you can accomplish this:
1. Use BPM and call the Oracle stored procedure using a receiver adapter via a asynch-synch bridge.
2. Develop a user-module for the adapter, which can be used with a sender adapter.
Thanks

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:

Any help is greatly appreciated,

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.

Simple call to stored function from asp (vbscript) adodb

please let me know if this question would be better suited to another forum.
i am simply attempting to call an oracle stored function that returns a varchar2 from an asp vbscript page using adodb. i have calling of stored procedures working fine.
attempting to call the function with the following code:
set sp_aprvd_cr = Server.CreateObject("ADODB.Command")
sp_aprvd_cr.ActiveConnection = MM_MHR_CONN_STR_STRING
sp_aprvd_cr.CommandType = 4
sp_aprvd_cr.CommandTimeout = 0
sp_aprvd_cr.Prepared = true
sp_aprvd_cr.CommandText = "PMS.sp_hpmsq054_aprvd_cr"
sp_aprvd_cr.Parameters.Append sp_aprvd_cr.CreateParameter("IP_PMSPT_ID", 200, 1,10,sp_aprvd_cr__P_PMSPT_ID)
sp_aprvd_cr.Parameters.Append sp_aprvd_cr.CreateParameter("return_param", adVarchar, adParamOutput)
set rst_aprvd_cr = sp_aprvd_cr.Execute
suspect that preparing the return code is where i am having troubles.
any examples or assistance would be greatly appreciated.
thanks in advance.

Return value from stored function must be the first parameter in the parameters collection.
So, try this instead,
sp_aprvd_cr.Parameters.Append sp_aprvd_cr.CreateParameter("return_param", adVarchar, adParamOutput)
sp_aprvd_cr.Parameters.Append sp_aprvd_cr.CreateParameter("IP_PMSPT_ID", 200, 1,10,sp_aprvd_cr__P_PMSPT_ID)Cheers,

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
Sub Macro1()
Dim StrSql As String
Dim ObjRs As New ADODB.Recordset
Dim I As Long
StrSql = "Provider=OraOLEDB.Oracle.1;Password=swallocation;Persist Security Info=True;User ID=swallocation;Data Source=dumpdb"
Set Objconn = New ADODB.Connection
Objconn.Open StrSql
For I = 2 To Sheet1.Rows.Count
If Not CStr(Sheet1.Cells(I, 1)) = "" Then
ObjRs.Open "select AddOne(" + CStr(Sheet1.Cells(I, 1)) + ") from dual", Objconn
If Not ObjRs.EOF And Not ObjRs.BOF Then
ObjRs.MoveFirst
Sheet1.Cells(I, 2) = ObjRs(0).Value
End If
ObjRs.Close
Else
Exit For
End If
Next
Set ObjRs = Nothing
Objconn.Close
Set Objconn = Nothing
End Sub
Hope you get something to start with

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);

ValueReadQuery query = new ValueReadQuery();
query.setCall(call);
query.addArgument("P_EMAIL_ADDRESS");
Vector parameters = new Vector();

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,
Chris

Running Stored functions from PHP

Hi all,
I cannot find any proper example in which it is detailed how to run an oracle stored function (or function within a package) from php.
i.e. this is my function
create or replace function myfunction return date is
begin
return sysdate;
end myfunction;
this is my php (but doesn't work)
function OracleExecutefunction($pconnection){
$sql = "declare v_date date; begin v_date:=myfunction; end;";
$result = OCIParse($pconnection,$sql) or OracleProblem();
OCIExecute($result, OCI_DEFAULT) or OracleProblem();
return $result;
This is what I get: Resource id #4
I would appreciate any help or much better a working example.
Cheers

OK, i have it working now by doing the following:
function OracleExecutefunction($pconnection){
$sql = 'select myfunction mdate from dual';
$result = OCIParse($pconnection,$sql) or OracleProblem();
OCIExecute($result, OCI_DEFAULT) or OracleProblem();
OCIFetch($result);
#echo "My function=" . ociresult($result, "MDATE");
return ociresult($result, "MDATE");
Is there any other better way of doing it?
Thanks

How to execute a procedure or function from Java Stored procedure

Hi,
I am new to Java Stored Procedures. I am working on Oracle 8i and JVM 1.3.1. I want to call a PL/SQL procedure from within Java. I have tried looking at severa; cources but they are quite high level for me. Can someone provide a simple example including the Source Code for .java file and also the calling function's code?
Heres a sample of what I have been working on: I an including Java code, and Function code and how I call the function. Instead of doing "select sysdate from dual" I want to do like "create table temp1(var1 varchar2(10))" or similar... like "exec procname(var1)" etc.
Thanks in advance.
PS. The variable passed in function is just a dummy variable.
