Sorry, I should have looked at your syntax more closely.
You can't open an existing database as an in memory database. If you want
to open an in memory database, the revopendatabase syntax is
revOpenDatabase("sqlite",":memory:") and it will be a brand new, empty
database with no tables. The syntax you used would have created a disk
database file named /Users/Dev/Documents/Ratings.db3:memory: with no tables
in it, hence the error message you got.
Hope that explains it better.
