Oracle Proc in edmx via add function import is not working

Question

I have a mandate to call a external oracle package from my local oracle db proc using Entity Framework. I have created a synonym for that. When I am trying to polpulate the oracle procedure data in my mvc screen using odp.net. The screen is closing automatically when I am trying to retive the column info by clicking "get column information" under "Add Function Import" in model browser.
Following is my code snipet
1. created a oracle stored proc to call the external proc
CREATE OR REPLACE PROCEDURE USP_GET_DETAILS
IN_ID IN NUMBER,
OUT_RESULT OUT SYS_REFCURSOR
IS
OUT_FED_TAX_ID_NO VARCHAR2(50);
OUT_PARTY_ID_NO NUMBER;
OUT_PARTY_TYP_CD NUMBER;
BEGIN
PKG_GET_DETAILS.USP_GET_DETAILS_INFO (IN_ID, OUT_FED_TAX_ID_NO, OUT_PARTY_ID_NO);
OPEN OUT_RESULT FOR
     SELECT OUT_FED_TAX_ID_NO, OUT_PARTY_ID_NO FROM DUAL;
END USP_GET_DETAILS;
2. added the proc "USP_GET_DETAILS" using "Update model using database" in my edmx file
3. Now proc has been added to my edmx file under SSDL
<Function Name="USP_GET_DETAILS" Aggregate="false" BuiltIn="false" NiladicFunction="false" IsComposable="false" ParameterTypeSemantics="AllowImplicitConversion" Schema="BCS_OWNER">
<Parameter Name="IN_ID" Type="number" Mode="In" />
</Function>
4. added following code to my web.config file
<oracle.dataaccess.client>
<settings>
<add name="BCS_OWNER.USP_GET_DETAILS.RefCursor.OUT_RESULT" value="implicitRefCursor bindinfo='mode=Output'" />
<add name="BCS_OWNER.USP_GET_DETAILS.RefCursorMetaData.OUT_RESULT.Column.0" value="implicitRefCursor metadata='ColumnName=OUT_FED_TAX_ID_NO;NATIVEDATATYPE=Varchar2;ProviderType=Varchar2'" />
<add name="BCS_OWNER.USP_GET_DETAILS.RefCursorMetaData.OUT_RESULT.Column.1" value="implicitRefCursor metadata='ColumnName=OUT_PARTY_ID_NO;NATIVEDATATYPE=Number;ProviderType=Decimal'" />
</settings>
</oracle.dataaccess.client>
5. underModel Browser try to add the procedure under "Add Import Function", select "Complex Type". when i am clicking on "Get column information" button, the screen blank for some time and then auto closing the screen without displaying any column info. I would like to know if any thing wrong i am doing on my steps? please help?

Answer 1

I managed to workaround this problem.
I add the function with no return value. Then in the Model Explorer you go to the properties of the imported function and edit the return type property, the same dialog appears, but this time it works as expected(considering you have set all the values correctly on your config file).
