I want to create a generic data layer that uses Oracle as the back end. By
generic, I just want a couple of procedures. All access will be done with
stored procs, and I want one that returns a dataset and one that returns a
datareader. I want to pass in the commandName, and a ParameterArray that
holds the parameters I want to populate:
Public Shared Function ExeCmd(ByVal CommandName As String, ByVal CmdParam as
OracleParameterCollection) as DataSet
Using z as new OracleCommand
with x
.CommandType = StoredProc
.CommandText = CommandName
'I want to iterate through the parameter collection and add
each parameter here
end with
End Using
End Function
How can I apply the ParameterCollection to the command?

I'm not sure how to do it in Oracle, but here's what i do for DB2.
Public Function Execute_Command(ByVal Command As DB2Command, ByVal
Parameters() As DB2Parameter, ByVal With_Return As Boolean) As
DB2DataReader
Dim Parameter As DB2Parameter
If Not Parameters Is Nothing Then
For Each Parameter In Parameters
' Only add it if something is actually there.
If Not Parameter Is Nothing Then
Command.Parameters.Add(Parameter)
Next Parameter
End If ' Not Parameters Is Nothing
' The command is ready. so, execute it, and grab the output, if
any.
' The information cannot be controlled by this statement, so
catch errors.
Try
If With_Return Then
Return Command.ExecuteReader
Else
Command.ExecuteNonQuery()
End If
Catch The_Exception As Exception
Report_error(The_Exception)
End Try
End Function
