Calling Stored Function from DOT NET

Hi,
I am trying to call a stored function "PKG_MIS_USER_MASTER.ADD_USER(userid varchar2, password varchar2) return NUMBER" from my DOT NET application.
Everything works fine within TOAD. Can anyone please help me in writing the C# code for calling a stored function along with its return value.
Thanks in Advance.

You can (as of 15-JUL-2005) get chapter 5 and chapter 7 of my book from the ODP.NET homepage, which is located here:
http://www.oracle.com/technology/tech/windows/odpnet/index.html
The link is at the bottom of the page.
The direct link is:
http://www.oracle.com/technology/books/pdfs/dotnet_ch5_7.pdf
Chapter 5 covers using PL/SQL from .NET.

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);
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?

Trying to call a function from C#

Hi all,
I am having problems calling a function that returns a sys refcursor and takes a varchar2 as an input. From the SQL Developer IDE I see that the function is run like
DECLARE
X_AR_MHTR VARCHAR2(200);
v_Return sys_refcursor;
BEGIN
X_AR_MHTR := 697678;
v_Return := CMS_SMS.FOR_WEB.WEB_STATION_1(
X_AR_MHTR => X_AR_MHTR
/* Legacy output:
DBMS_OUTPUT.PUT_LINE('v_Return = ' || v_Return);
:v_Return := v_Return; --<-- Cursor
END;
here is my C# code
public static void getTilemetriseis(bool isLemessos, string AMSet, out OracleDataReader dr)
DataSet ds = new DataSet();
OracleDataAdapter ad = new OracleDataAdapter();
OracleCommand cmd = new OracleCommand();
cmd.CommandType = CommandType.StoredProcedure;
cmd.CommandText = "CMS_SMS.FOR_WEB.WEB_Station_1";
if (isLemessos)
cmd.Parameters.Add("X_AR_MHTR", OracleDbType.Varchar2, ConfigurationManager.AppSettings["LemessosArMhtr"].ToString(), ParameterDirection.Input);
cmd.Parameters.Add(new OracleParameter("anexoflCur", OracleDbType.RefCursor, ParameterDirection.ReturnValue));
// ad.SelectCommand.CommandText = string.Format(@"select m_code,ar_mhtr,city,address,stcode
// from cms_sms.FOR_WEB.flowmetersall where ar_mhtr = {0}
// order by length(ar_mhtr),ar_mhtr", ConfigurationManager.AppSettings["LemessosArMhtr"].ToString());
else
cmd.Parameters.Add("X_AR_MHTR", OracleDbType.Varchar2, "697678", ParameterDirection.Input);
cmd.Parameters.Add(new OracleParameter("v_Return", OracleDbType.RefCursor, ParameterDirection.ReturnValue));
// ad.SelectCommand.CommandText = string.Format(@"select m_code,ar_mhtr,city,address,stcode
// from cms_sms.FOR_WEB.flowmetersall where ar_mhtr= -1
// order by length(ar_mhtr),ar_mhtr", AMSet);
cmd.Connection = OracleDBManager.getOracleCMSConnection();
cmd.ExecuteNonQuery();
dr = (OracleDataReader)cmd.Parameters["v_Return"].Value;
cmd.Connection.Close();
The error rises on cmd.ExecuteNonQuery() and is described as
ORA-06550:
PLS-00306: wrong number or type of argument
Any ideas?

Off the top of my head, your parameter type on the second parameter is wrong. The function doesn't have a return value, one of the parameters contains it. So the second parameter's type can't be ReturnValue (should be output).
Either that or change the function to only have one parameter and add RETURN sys_refcursor into the definition, at which point you can use ReturnValue.

Cannot call ANY stored functions from my Java program

My problem is that I cannot call ANY stored procedure from my Java

very well in PL/SQL:
PL/SQL code:

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.

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;

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

Transfer data from dot net to sap system

Hi gurus!
please , help me out , i wanna transfer data from dot net to sap system. i have no idea abt it.
Points can be given sure!!!!!!
Rahul Deshmukh

Hi,
You need to create a RFC(Remote Function Call) to achieve this.
Goto Transaction SE37
Import Parameters(What all data you are going to pass from JAVA to SAP)
EXPORT parameters(What all data you want to pass from SAP to JAVA)
TABLES parameters (What all tables you want to pass from JAVA to SAP)
Goto Attributes tab & select Remote Enabled.
Do the coding to insert records in ZTABLE.
Activate the RFC
Now, in JAVA code to login to sap & call the RFC with the required data.

Calling Stored procedure from Forms 6i

Dear all,
I have a stored procedure having INand INOUT parameters. I need to call it from Forms 6i triggers. Will you please tell me the syntax for calling stored procedure and stored function from Forms 6i and report 6i.

[email protected]

Just the same as for a local procedure, the only restrictions concern package public variables which are not visible from client side PL/SQL, and you probly want to keep the interfaces simple as client side PL/SQL (e.g. the Forms and Reports engines) don't support the same range of datatypes that the database does.

How to call stored procedure from Pro*C

How to call stored procedure from Pro*C ?

my Pro*C code is the following..
EXEC SQL EXECUTE

test_procedure();

the test_procedure() has a simple update statement. and it works well in SQL Plus consol. but in Pro*C, there is a precompile error.
will anybody help me what is the problem ??

I'm in the process of moving C files (with embedded SQL, .PC files) from Unix to Linux. One program I was trying to compile had this piece of code that called an Oracle function (a standalone), which compiled on Unix, but gives errors on Linux:
EXEC SQL EXECUTE

:r_stat := TESTSPEC.WEATHER_CHECK();
END;

Calling Stored Function

Hi all,
Trying to call a stored function from vfp5 using odbc, not ado. I'm having issues with the correct syntax of the statement. Can I not use the standard vfp sqlexec() command? ( i.e. sqlexec( connhandle, "{call package.function()}, "returncursor" ) Any help would be great since my customer has no clue on this, and frankly, neither do I.

This is supported in the next code drop of the XSQL Servlet. Due out on OTN in the next couple of weeks.

How to call a function from asp

if err.description <> "" then
response.write ("No se pudo! :(")
else

end if
rs.close
set rs = nothing
but there is an error:
ORA-06576: not a valid function or procedure name
Please is very urgent!!!
Thanks.
Angie.

You need to use the syntax "{call <procedure_name>}".
The {call } syntax tells the OLE DB provider that it needs to translate the call into whatever the database's procedure calling syntax is. This means that even though different databases have different syntax for calling stored procedures, your OLE DB code can be run against any of them without changing.

Calling stored procedures from entity object and application module

Hello
I've put in place an EntiyImpl base class containg helper methods to call stored procedures.
I now need to call stored procedures from the application module.
Apart from creating an application module base class and duplicating the helper method code is there a way
to share the helper methods for calling stored procedures between the entity impl and application module impl ?
Regards
Paul

Does the helper code depend on features of a particular entity object instance, beyond its database transaction?
If so, I'm not sure I see how it could be used from an application module class.
If not, here's what you do:
Step 1:
Parametrize the database transaction--you might even want to. So instead of
protected myHelperMethod(Object someParam) {
DBTransaction trans = getDBTransaction();
change this to
protected myHelperMethod(DBTransaction trans, Object someParam) {
Step 2: make the method public and static--once you parameterize the DBTransaction, you should be able to do this.
public static myHelperMethod(DBTransaction trans, Object someParam) {
Step 3: Remove the method from your EntityImpl base class into a utility class:
public abstract class PlSqlUtils {
private PlSqlUtils() {}
public static myHelperMethod(DBTransaction trans, Object someParam) {
When you want to call the method from an application module, entity object, or even view object class, call
PlSqlUtils.myHelperMethod(getDBTransaction(), paramValue);
Unlike Transaction.executeCommand(), this lets you provide functionality like setting procedure parameter values, retrieving OUT parameter values, etc.
Hope this helps,

Calling Stored Procedures from Discoverer

Does anyone know if I can call stored procedures from Discoverer? I know it supports Registered PL/SQL functions. If yes, can I find any documentation. Any information will be very helpful.
Thanks in advance!

One way I can think of to do that would be to use function with pragma restrict references. You can then use the function as a column in a SQL query to make a folder in Discoverer.
