You use the Tabular Model Scripting Language (TMSL) in SQL Server 2016. When you run a JavaScript Object Notation (JSON) based statement script, you see from the SQL Profiler that the Analysis Management Objects (AMO) instance is enumerating corresponding events with class CommandBegin and CommandEnd and subclass JsonCommand. But when you subscribe to events programmatically, TraceEventSubclass does not enumerate events of subclass JsonCommand.


The fix for this issue is included in the following cumulative update for SQL Server:

Cumulative Update 1 for SQL Server 2016
Note This fix can be obtained by installing a new version of the AMO assemblies on the client computer.

Each new cumulative update for SQL Server contains all the hotfixes and all the security fixes that were included with the previous cumulative update. Check out the latest cumulative updates for SQL Server:
