Question

We have a Procedure in Oracle with a SYS_REFCURSOR output parameter that returns the data we want to bind to an ASP.NET GridView control. I’ve seen this done before but I can’t find the original reference I used to solve the problem.

Here is what the procedure looks like:

create or replace PROCEDURE GETSOMEDATA (     P_Data OUT SYS_REFCURSOR ) AS BEGIN     OPEN P_Data FOR SELECT * FROM SOMETABLE; END GETSOMEDATA; 

And for now the GridView is just bare-bones:

<asp:GridView ID='grdData' runat='server' AutoGenerateColumns='true'></asp:GridView> 

Answer 1

Try something like: (didn’t specify which language)

    Public Function GetSomeData() as DataTable         Dim OrclConn as New OracleConnection('Connectionstring')         Dim OrclCmd as New Oraclecommand('GETSOMEDATA', OrclConn)         OrclCmd.CommandType = CommandType.StoredProcedure         OrclCmd.Parameters.Add('P_Data', OracleType.Cursor).Direction = ParameterDirection.Output 'Or ParameterDirection.ReturnValue          Dim OrclDA as New OracleDataAdapter(OrclCmd)         Dim RtnTable as DataTable         OrclConn.Open         OrclDA.Fill(RtnTable)         OrclConn.Close          Return RtnTable     End Function
