谁给说说中间层AS_GetRecords函数的用法，越详细越好，在线等待

幫助上的
Returns a data packet that contains the specified data.
Delphi syntax:
function AS_GetRecords(const ProviderName: WideString, Count: Integer;
out RecsOut: Integer;
Options: Integer;
const CommandText: WideString;
var Params: OleVariant;
var OwnerData:OleVariant): OleVariant;
safecall;

IAppServer.AS_GetRecords==>TDataSetProvider.GetRecords==>TClientDataSet.GetNextPacket(PacketRecords>0 and FetchOnDemand=false) or TClientDataSet.Data(PacketRecords=-1 and FetchOnDemand=True)
