Thanks for the replies.
Allowing non-aggregate columns in aggregate queries is very useful, as
shown with the min/max functions.
Probably with this feature comes that SQLite even allows all non-aggregate
columns in SELECTs with GROUP BY. Perhaps the documentation should warn
more clearly, that in

It is forbidden in most SQL dialects, only supported by SQLite
as a dirty shortcut.

The feature in last paragraph is already the case with plain ORDER BY. All

run the command-line shell on iOS? Can you explain to us how you do
that, because that is not somet
Just wonder what the possible use for this is.

Consider a function which INSERT's into the model and then INSERT's a log
table row. The caller probably isn't interested in the log rowid.
A better question to ask is always why an

I have checked in changes (written by Dan) that should address your
