How to obtain the "affected row count" of a call to TSQLRest.Execute?
Sometimes after executing a DELETE/UPDATE statement, we need to examine the affected row count and I remember the SQLITE engine itself provides this feature. How to get that info out of TSQLRest? Thanks.

It is not possible, since it is not desired.
You should not use TSQLRest.Execute() from a client.
It is unsafe, and is to be disabled on any serious production system.
Write a persistence service instead, and call you custom SQL on the server side.
Using SynSQLite3, you are able to call TSQLDataBase.LastChangeCount.
Using SynDB, use ISQLDBStatement.UpdateCount.

Actually I'm talking about the server side 
I see now, access TSQLRestServerDB.DB.LastChangeCount.
Thanks!
