Entity framework cannot "add function import" for Oracle stored procedure

I am using Entity framework with the following tools:

• MS Visual studio 2010 Professional SP1

• Latest Oracle Data Provider from Oracle website. (ODAC 11.2 Release 4 (11.2.0.3.0) for 32 bit) Downloaded from http://www.oracle.com/technetwork/topics/dotnet/index-085163.html

• Oracle Server 11g

My table looks like this

my stored procedure looks like this:

PROCEDURE "GET_SUPPLIERS" (
    "SUPP_LIST" OUT SYS_REFCURSOR) IS
BEGIN 

    OPEN SUPP_LIST FOR 
    SELECT 
        SUPPLIER_NAME 
    FROM 
        A_SUPPLIER  ;

END;

      

        
        
        
      

    

I updated the app.config for my entity infrastructure project as follows:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <connectionStrings>
    <add name="Entities" connectionString="tookitoutfromhere" />
  </connectionStrings>


  <oracle.dataaccess.client>
    <settings>
      <add name="FSDEVTL.GET_SUPPLIERS.RefCursor.SUPP_LIST" value="implicitRefCursor bindinfo='mode=Output'" />
      <add name="FSDEVTL.GET_SUPPLIERS.RefCursorMetaData.SUPPLIER_NAME.Column.0" value="implicitRefCursor metadata='ColumnName=SUPPLIER_NAME;BaseColumnName=SUPPLIER_NAME;BaseSchemaName=FSDEVTL;BaseTableName=A_SUPPLIER;NATIVEDATATYPE=Varchar2;ProviderType=Varchar2'" />
    </settings>
  </oracle.dataaccess.client>


</configuration>

      

        
        
        
      

    

I follow these steps:

In my .edmx project -> Model.Store -> Stored Procedures -> GET_SUPPLIERS

right click the stored procedure "GET_SUPPLIERS" select "add import function" The function name and stored procedure name are prepopulated In the Returns collection section I select Entities as a_supplier which is an imported Oracle table. Then I click the Get Column Information button.

I am getting a response titled "The selected stored procedure does not drop columns".

Please, help.

I would like to be able to get a set of records from a stored procedure into my .net classes via entity framework.

thank
