The following example creates an OdbcParameter and sets some of its properties.

Public Sub CreateOdbcParameter()
   Dim parameter As New OdbcParameter("Description", OdbcType.VarChar, 88)
   parameter.IsNullable = True
   parameter.Direction = ParameterDirection.Output
End Sub

public void CreateOdbcParameter()
{
   OdbcParameter parameter = new OdbcParameter("Description", OdbcType.VarChar, 88);
   parameter.IsNullable = true;
   parameter.Direction = ParameterDirection.Output;
}

Null values are handled using the DBNull class.
