Question

I am using Entity framework with following tools:

1. MS Visual studio 2010 Professional SP1

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

3. Oracle 11g server

My table looks as follows

my stored proc looks as follows:

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

    OPEN SUPP_LIST FOR 
    SELECT 
        SUPPLIER_NAME 
    FROM 
        A_SUPPLIER  ;

END;

I updated app.config for my entity framework 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 execute the following steps:

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

right click the stored procedure “GET_SUPPLIERS”
choose “add function import”
Function Import name and Stored procedure name are pre populated
Under Returns a collection of
I choose Entities as a_supplier which is the imported Oracle table.
Then I click on “Get column information” button.

I get a response called “The selected stored procedure retuns no columns.”

Please help.

I would like to be able to get recordset from stored procedure into my .net classes via entity framework.

Thanks

Please choose complex in “returns a collection of” and try again.
