Sqlite (Mono.Data.Sqlite)
the Create table command is implemented, but disabled by default due to a bug in the sqlite database provider (https://bugzilla.novell.com/show_bug.cgi?id=324934), the feature will be enabled by default when the bugfix hits a mainstream mono version (probably mono 1.2.5.1 or 1.2.6)
