Not useful.
The component provides a service action that executes a query that only works for SQL Server and determines @@servername, @@servicername, and @@VERSION.
Because normal set ups of OutSystems have the DEV and TST environments sharing the same database, it will not be possible to distinguish the environments.
Also, it is necessary to customize the component, replacing some values hardcoded in the query, for it to work for a real scenario.
Example of normal values are:
ServerName: EC2AMAZ-HQM60MQ
ServiceName: MSSQLSERVER
