Returning ref cursor from oracle stored procedure by using DAAB from MS EntLib 4.1

Is it possible开发者_高级运维 to get ref cursor from oracle stored procedure by using DAAB from Microsoft Enterprise Library 4.1?

Yes, surely you can.

PROCEDURE load_all (
    p_row_start          IN     number,
    p_page_size          IN     number,

    cur_out              OUT    sys_refcursor
) AS
...

And on the C# side:

DbCommand cmd = db.GetStoredProcCommand("my_package.load_all", paramValues))
IDataReader r = db.ExecuteReader(cmd);
...

RefCursor param supposed to be named "cur_out".

DAAB does not provide a capability for us to get the Ref Cursor. The issue is System.Data.Common does not have DbType.Cursor or DbType.RefCursor type. So, there is a bit of tweaking required in the DAAB 4.1 source code. Please follow the steps provided in the following link. It works like a piece of cake.
