The driver should convert Int64 to Bignum, using e.g. Kernel#Integer:
i64 = System::Int64.new(1000000000000)
=> 1000000000000 (Int64)
Integer(i64)
=> 1000000000000
Integer(i64).class
=> Bignum

Only problem i’ve ran into with this method for now has been the usage
of System::Int64 for Primary keys.
In a join table it was storing the yaml representation of the Int64
object instead of the proper Integer value,
as a quick patch I’ve applied the following but i’m sure there is a
better safer way;
class System::Int64
def to_i; self.to_s.to_i; end
end

I went out of my way and decided to have a look at updating the SQlite
dll.
It seems the interface has changed since sqlite3-ironruby gem release.
I have downloaded and put the Community.CsharpSqlite.dll in the native
folder:
http://code.google.com/p/csharp-sqlite/downloads/list?can=1&q=&colspec=Filename+Summary+Uploaded+ReleaseDate+Size+DownloadCount
Then I have adjusted driver.rb to:
http://pastebin.com/diff.php?i=7e522Rvs
Most things seem to just work, and it’s blazing fast now, about as fast
as Ruby 1.9.2’s sqlite3 performance!
I thought i’d let you know in case experiencing similair issues

writes slow, reads fast
Hello,
I am since some weeks working with IronRuby.
I do not consider myself a great programmer in neither Ruby or .NET, yet
I really love Ruby, and in these past few weeks IronRuby and .NET in
general has really grown on me; very powerful!
So first; my gratitude for this amazing product, thanks to all who make
this possible!
My project’s available @ Github:
https://github.com/sickboy/six-updater-gui
My current issue is that SQLite writes seem to take at least 0.7 seconds
per write.
So if I update 100 records at once in 1 query, it will take ~0.8s.
But also if I update 1 record, it will take ~0.7s…
In comparison, the same actions with mingw Ruby 1.9.2 (from
RubyInstaller.org), these writes take only about 0.005s
Reads seem to be okay.
Is this a known problem? Is there anything that can be done about this?
Do others see these long delays as well? How about msSQL (/Express)?
Not sure if I should create a seperate mail thread for this;
The second problem i’m having is that when I load a database model with
ActiveRecord 2.3.8 into a BindingList, and that to a BindingSource, and
assign it to a DataGridView, everything is fine.
When I use ActiveRecord 3.03, I get “A singleton class has no underlying
system type”. Unless I don’t add records to the binding list, before
assigning the BindingSource as data_source of the DataGridView, and
instead, add records to the binding list after assigning the
data_source.
I am not sure how I should debug this problem.
Lastly I have the feeling (based on timing results in my logs) that
processing IronRuby scripts is faster when they run through the ir.exe
interpreter, than when they are executed in an engine from within a c#
app.
Could that be because certain optimizations are enabled in ir.exe, or
something similair?
Thanks for your time!
