I wish this helpful for you :items is the table name. That's just Sequel's syntax for indicating which table you want to insert into.

wish helps you Found the solution on this thread: Unable to connect mysql from Sequel gem
Call gem('mysql') to specify use of the native sql driver before Sequel.connect().

I wish this helpful for you Ruby will automatically close the database connection sockets on process shutdown, so you don't need to call DB.disconnect manually (though you can if you want to).

I wish did fix the issue. There are some problems I detected:
Here you add the cities with downcase:
code :
    cities.each do |city|
        begin
            DB[:locations].insert(:name => city.downcase)
        rescue Sequel::UniqueConstraintViolation
            puts "Duplicate, not added"
        end
    end
    allLocs = DB[:locations].where(:name => cities).order(:name).all
allLocs = DB[:locations].where(:name => cities.map(&:downcase)).order(:name).all
        addDist(toLoc, fromLoc)
        addDist(toLoc[:id], fromLoc[:id])
DB[:distances].insert(:to=>tos[:id], :from=>froms[:id])
selection = DB[:locations].where(:name => cities.map(&:downcase)).order(:name)
selection.each{|toLoc|
  selection.each{|fromLoc|
        puts toLoc.to_s + " : " + fromLoc.to_s 
        #If you comment out the line below everything runs fine, minus the insertion obviously
        addDist(toLoc[:id], fromLoc[:id])
   }
}

Hope that helps You didn't provide an executable setup, so I haven't tested this, but I think it will work. The basic idea is to just add a constant column of results to your select.
code :
reports = db[:reports]
report_columns = [:user_id, :purchase_date, :sku, :channel]

spoons_select_graph = {
  user_id: :users,
  purchase_date: :spoon_receipts,
  product_id: :spoon_receipts,
  channel: [:spoon_receipts, :channel, 'spoons']
}
spoons = db[:spoon_receipts]
spoons_select = spoons.graph(:users, user_id: :user_id).set_graph_aliases(spoons_select_graph)

reports.disable_insert_returning.insert(report_columns, spoons_select)
