const items = {
  type: new GraphQLList(Type),
  description: 'get item list',
  args: {
    limit : { type: IntType},
    skip  : { type: IntType},
    order : { type: StringType},
    name  : { type: StringType},
  },
  resolve( request, args, session) {
    const options = wQueryS(args);
    return Model.findAll(options);
  }

{items(limit:16, order:'-updatedAt', name:"~test" ){id name}}

SELECT * FROM `Items` WHERE LOWER(`name`) LIKE '%test%' ORDER BY `Items`.`updatedAt` DESC LIMIT 16;
