Hi,
I'm currently using the following to return data from a stored proc and populate a mem table.
        RtcDataSetFieldsToDelphi(RtcValue1.asDataSet, gridT);
        gridT.CreateTable;
All great, however some stored procs return multiple datasets  Roll Eyes
and only the first is returned
Is there currently any way to retrieve multiple dataset results ?

thanks
Ron

You can store any data structure you want with TRtcValue objects (any field inside a TRtcDataSet, TRtcRecord, TRtcArray and TRtcFunctionInfo object can be of any data type - including these complex data types) and send it with RTC Remote Functions, but ... you need your own functions for copying data from a TDataSet to TRtcDataSet and back if you are sending complex data types like nested datasets or some other database-specific field types, because functions provided in the "rtcDB.pas" unit ONLY serve as basic examples and can ONLY handle the most basic data types.

In other words, you can copy "RtcDataSetFieldsToDelphi" and other related functions from the "rtcDB.pas" unit into your own unit (give each function a new name) and modify them to do what you need, or ... just use these functions as examples (that's what they actually are) and write your own.
