Description
Returns the current parameter values of the dataset.
The provider component calls PSGetParams to implement its GetParams method.
PSGetParams returns a TParams object that describes the current values of all parameters of the dataset. If the dataset does not have any parameters, PSGetParams returns nil (Delphi) or NULL (C++).
This method is an implementation of the IProviderSupport.PSGetParams method and, by default, returns nil for Delphi and NULL for C++, because TDataSet does not implement a provider by default. To use it, every TDataSet descendant must override it in its specific way.
