Calling #to_a on a ResultSet seems to clear the result, so that the next time #to_a returns an empty array. Is this intended?
$ cat test.rb
require 'sqlite3'
db = SQLite3::Database.new( "./test.sqlite" )
db.type_translation = true
db.execute <<END
create table if not exists t (
x real
)
END
db.execute "insert into t values (1)"
qry = db.prepare "select * from t"
res = qry.execute
p res.to_a
p res.to_a
$ ruby test.rb
