client = Trilogy.new(host: "127.0.0.1", port: 3306, username: "root", read_timeout: 2)
if client.ping
  client.query_options[:database_timezone] = :utc
  client.change_db "mydb"

  result = client.query("SELECT id, created_at FROM users LIMIT 10")
  result.each_hash do |user|
    p user
  end
end

mysql2 gem compatibility

The trilogy API was heavily inspired by the mysql2 gem but has a few notable differences:

• The query_options hash doesn't inherit from the connection options hash. This means that options like turning on/of casting will need to be set before a query and not passed in at connect time.
• For performance reasons there is no application_timezone query option. If casting is enabled and your database timezone is different than what the application is expecting you'll need to do the conversion yourself later.
• While we still tag strings with the encoding configured on the field they came from - for performance reasons no automatic transcoding into Encoding.default_internal is done. Similarly to not automatically converting Time objects from database_timezone into application_timezone, we leave the transcoding step up to the caller.
• There is no as query option. Calling Trilogy::Result#each will yield an array of row values. If you want a hash you should use Trilogy::Result#each_hash.
