Two issues:

- When running a tag event, the script is outside any normal project scope, and therefore has no default database. The optional parameter to `system.db.runQuery` for the database is **not optional** in this situation.

- Running any kind of database query, unless it **always** executes extremely quickly (single-digit milliseconds), is inappropriate in tag event scripts. Use a gateway tag change script instead (in the project, subscribed to the reference tag, not **on** the reference tag).

{ Failure to follow the fast-execution rule for tag events can crush your entire system. }
