Tuple

Tuples group small amounts of data together and stores the data in a single column.

Prerequisites

  • Keyspace exists

  • Table exists

  • Tuple column exists

  • Insert tuple data into the table cycling.route. Note that the tuple is enclosed in parentheses. This tuple has a tuple nested inside; nested parentheses are required for the inner tuple, then the outer tuple.

CREATE TABLE IF NOT EXISTS cycling.route (
  race_id int,
  race_name text,
  point_id int,
  lat_long tuple<text, tuple<float, float>>,
  PRIMARY KEY (race_id, point_id)
);
INSERT INTO cycling.route (
  race_id, race_name, point_id, lat_long
) VALUES (
  500, '47th Tour du Pays de Vaud', 1, ('Onnens', (46.8444, 6.6667))
);

INSERT INTO cycling.route (
  race_id, race_name, point_id, lat_long
) VALUES (
  500, '47th Tour du Pays de Vaud', 2, ('Champagne', (46.833, 6.65))
);

INSERT INTO cycling.route (
  race_id, race_name, point_id, lat_long
) VALUES (
  500, '47th Tour du Pays de Vaud', 3, ('Novalle', (46.833, 6.6))
);

INSERT INTO cycling.route (
  race_id, race_name, point_id, lat_long
) VALUES (
  500, '47th Tour du Pays de Vaud', 4, ('Vuiteboeuf', (46.8, 6.55))
);

INSERT INTO cycling.route (
  race_id, race_name, point_id, lat_long
) VALUES (
  500, '47th Tour du Pays de Vaud', 5, ('Baulmes', (46.7833, 6.5333))
);

INSERT INTO cycling.route (
  race_id, race_name, point_id, lat_long
) VALUES (
  500, '47th Tour du Pays de Vaud', 6, ('Les Clées', (46.7222, 6.5222))
);
  • Insert tuple data into the column info in the table cycling.nation_rank. The info column stores the rank, name, and point total of each cyclist. The tuple is enclosed in parentheses.

CREATE TABLE IF NOT EXISTS cycling.nation_rank (
  nation text PRIMARY KEY,
  info tuple<int, text, int>
);
INSERT INTO cycling.nation_rank (
  nation, info
) VALUES (
  'Spain', (1, 'Alejandro VALVERDE', 9054)
);

INSERT INTO cycling.nation_rank (
  nation, info
) VALUES (
  'France', (2, 'Sylvain CHAVANEL', 6339)
);

INSERT INTO cycling.nation_rank (
  nation, info
) VALUES (
  'Belgium', (3, 'Phillippe GILBERT', 6222)
);

INSERT INTO cycling.nation_rank (
  nation, info
) VALUES (
  'Italy', (4, 'Davide REBELLINI', 6090)
);
  • Insert tuple data into the column cinfo in the table cycling.popular. The cinfo column stores the country name, cyclist name, and points total.

CREATE TABLE IF NOT EXISTS cycling.popular (
  rank int PRIMARY KEY,
  cinfo tuple<text, text, int>
);
INSERT INTO cycling.popular (
  rank, cinfo
) VALUES (
  1, ('Spain', 'Mikel LANDA', 1137)
);

INSERT INTO cycling.popular (
  rank, cinfo
) VALUES (
  2, ('Netherlands', 'Steven KRUIJSWIJK', 621)
);

INSERT INTO cycling.popular (
  rank, cinfo
) VALUES (
  3, ('USA', 'Matthew BUSCHE', 230)
);

INSERT INTO cycling.popular (
  rank, cinfo
) VALUES (
  4, ('Italy', 'Fabio ARU', 163)
);

INSERT INTO cycling.popular (
  rank, cinfo
) VALUES (
  5, ('Canada', 'Ryder HESJEDAL', 148)
);
