        !            15: \f0\fs24 This example shows how to evaluate any arbitrary SQL statement or stored procedure by using a subclass of DBBinder, called MultiBinder. This example has been designed to be used with  the 3.1 Sybase Adaptor, so that you can get a non-rectangular result set from the evaluation of the stored procedure. However, it could theoretically work with other adaptors as well. \

This object extends the DBBinder functionality. In particular, it adds the ability to notify the DBBinder delegate when a new result set has been fetched from the binder. Thus, one can get multiple result sets from a stored procedure evaluation. Note that this feature is only valid starting with NextStep Release 3.1. \
