But my question is about DataSnap because the value of the sequence is changed while reading the client layer. Command; LMemTable. Also, one question: since you are about the only one with any experience with both of these methods, have you noticed any performance difference between these two REST architectures? Learn more about Teams. I use technical standards that the Embarcadero indicates. See this firebirdsql generatorguide-basics. Thank you for feedback. When you get the REST server data, this is returning records, the first 50 records are supressed. Create; if not FDMemTable1. So if you execute that query from your app and from ISQL, it gets increased twice.

In practice, however, even Delphi's own clients don't support this with REST Only in XE7 a better support for sending FireDAC datasets over. FireDAC enables native high-speed direct access from Delphi to InterBase, Informix, DataSnap and more, including the NoSQL Database MongoDB.
