Note
We assume that you already created the tables in step Creating a table and populated them with data in step Adding data to a table.
SELECT
sa.title AS season_title, -- sa and sr are "join names",
sr.title AS series_title, -- table aliases declared below using AS.
sr.series_id, -- They are used to avoid
sa.season_id -- ambiguity in the column names used.
FROM
seasons AS sa
INNER JOIN
series AS sr
ON sa.series_id = sr.series_id
WHERE sa.series_id = 1
ORDER BY -- Sorting of the results.
sr.series_id,
sa.season_id -- ORDER BY sorts the values by one column
; -- or multiple columns.
-- Columns are separated by commas.
