ddefed03e6 Don’t allow use of $ param with no value in queries 
Beforehand it was possible to do  SELECT * FROM $  which would show all of the variables defined. This is now not possible, and variables must be specified using their defined name.

47e1a4aceb Fix a bug with virtual records in scoped queries 
When querying a virtual document, it would check that the scope had permission to view the record, even though the record did not actually belong to a table.

Not it checks to see if the record is a virtual in-memory record, and does not perform any permissions checks if this is the case.

d2a451345a Don’t alter subquery RETURN type 
Don’t alter the RETURN type for CREATE / UPDATE / DELETE / RELATE / INSERT / UPSERT statements. Not only does this cause unexpected behaviour, but it also altered the statement from multiple goroutines, and therefore caused a data race.
