The query extension adds a query method which allows a different way to construct queries instead of the usual method chaining:

  dataset = DB[:items].query do
    select :x, :y, :z
    filter{(x > 1) & (y > 2)}
    reverse :z
  end

You can load this extension into specific datasets:

  ds = DB[:table]
  ds = ds.extension(:query)

Or you can load it into all of a database‘s datasets, which is probably the desired behavior if you are using this extension:

  DB.extension(:query)
