Create a Table
Run clickhouse-client and execute the following CREATE query:
CREATE TABLE recipes(title String,ingredients Array(String),directions Array(String),link String,source LowCardinality(String),NER Array(String)) ENGINE = MergeTree ORDER BY title;
Insert the Data
Run the following command:
clickhouse-client --query "INSERT INTO recipesSELECTtitle,JSONExtract(ingredients, 'Array(String)'),JSONExtract(directions, 'Array(String)'),link,source,JSONExtract(NER, 'Array(String)')FROM input('num UInt32, title String, ingredients String, directions String, link String, source LowCardinality(String), NER String')FORMAT CSVWithNames" --input_format_with_names_use_header 0 --format_csv_allow_single_quote 0 --input_format_allow_errors_num 10 < full_dataset.csv
This is a showcase how to parse custom CSV, as it requires multiple tunes.
Explanation:
- The dataset is in CSV format, but it requires some preprocessing on insertion; we use table function input to perform preprocessing;
- The structure of CSV file is specified in the argument of the table function input;
- The field num (row number) is unneeded - we parse it from file and ignore;
- We use FORMAT CSVWithNames but the header in CSV will be ignored (by command line parameter --input_format_with_names_use_header 0), because the header does not contain the name for the first field;
- File is using only double quotes to enclose CSV strings; some strings are not enclosed in double quotes, and single quote must not be parsed as the string enclosing - that’s why we also add the --format_csv_allow_single_quote 0 parameter;
- Some strings from CSV cannot parse, because they contain \M/ sequence at the beginning of the value; the only value starting with backslash in CSV can be \N that is parsed as SQL NULL. We add --input_format_allow_errors_num 10 parameter and up to ten malformed records can be skipped;
- There are arrays for ingredients, directions and NER fields; these arrays are represented in unusual form: they are serialized into string as JSON and then placed in CSV - we parse them as String and then use JSONExtract function to transform it to Array.
