Binding ASP.NET GridView to an Oracle SYS_REFCURSOR

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 2

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

Dim oracon As New OracleConnection("User Id=developer;Password=developer;Data Source=orcl;") Dim ds As New Data.DataSet Dim qry As String oracon.Open() qry = "select * from Employee" Dim adp As New OracleDataAdapter(qry, oracon) adp.Fill(ds) GridView1.DataSource = ds GridView1.DataBind() oracon.Close()
