Набор данных кулинарных рецептов от RecipeNLG доступен для загрузки [здесь](https://recipenlg.cs.put.poznan.pl/dataset). Он содержит 2.2 миллиона рецептов, аего размер чуть меньше 1 ГБ.
- набор данных представлен в формате CSV и требует некоторой предварительной обработки при вставке. Для предварительной обработки используется табличная функция [input](../../sql-reference/table-functions/input.md);
- при загрузке используется `FORMAT CSVWithNames`, но заголовок в CSV будет проигнорирован (параметром командной строки `--input_format_with_names_use_header 0`), поскольку заголовок не содержит имени первого поля;
- в файле CSV для разделения строк используются только двойные кавычки. Но некоторые строки не заключены в двойные кавычки, и чтобы одинарная кавычка не рассматривалась как заключающая, используется параметр `--format_csv_allow_single_quote 0`;
- некоторые строки из CSV не могут быть считаны корректно, поскольку они начинаются с символов`\M/`, тогда как в CSV начинаться с обратной косой черты могут только символы `\N`, которые распознаются как `NULL` в SQL. Поэтому используется параметр `--input_format_allow_errors_num 10`, разрешающий пропустить до десяти некорректных записей;
- массивы `ingredients`, `directions` и `NER` представлены в необычном виде: они сериализуются в строку формата JSON, а затем помещаются в CSV — тогда они могут считываться и обрабатываться как обычные строки (`String`). Чтобы преобразовать строку в массив, используется функция [JSONExtract](../../sql-reference/functions/json-functions.md).
В этом примере используется функция [has](../../sql-reference/functions/array-functions.md#hasarr-elem) для проверки вхождения элемента в массив, а также сортировка по количеству шагов (`length(directions)`).
