Fetches current parameter values from the dataset bound to a specified provider.
function AS_GetParams(const ProviderName: WideString; var OwnerData: OleVariant): OleVariant; safecall;
__fastcall OleVariant AS_GetParams(const BSTR ProviderName, OleVariant OwnerData);
Use AS_AS_GetParams to retrieve the current parameter values from the dataset associated with a provider.
The ProviderName parameter specifies the name of the provider component whose dataset has the parameters.
The OwnerData represents custom information that originates in a client dataset's BeforeAS_GetParams event handler and returns information that is passed to the client dataset's AfterAS_GetParams event handler.
AS_GetParams_result (C++) or AS_AS_GetParams (Delphi) returns the parameters, encoded as a Variant array, where each element is a 2-element Variant array containing a parameter name and a parameter value. These parameters can be converted to a TParams object using the UnpackParams procedure. If the dataset has no parameters, or if the provider does not support parameter fetching, AS_GetParams_result (C++) or AS_AS_GetParams (Delphi) returns a Null Variant.
