JIS X 0401 都道府県コード JSON

Last updated at Posted at 2020-04-22

概要

JIS X 0401:1973「都道府県コード」とISO 3166-2:2013:JP「国の下位区分コード」を結合して、都道府県名の漢字、カナ、英字表記をJSONデータに整備してみた。

都道府県コード JSON

以下のリンクからダウンロード可能
都道府県コードJSON

  • "code":都道府県等コード
  • "name":都道府県名(漢字)
  • "kana_name":都道府県名カナ
    • "half_upper":半角カナ(拗音・促音大書き)
    • "full_lower":全角カナ(拗音・促音小書き)
  • "en_name":都道府県名英字
    • "en":ISO 3166-2:JPのLanguage codeがenのもの
    • "ja":ISO 3166-2:JPのLanguage codeがjaのもの
  • "start_date":適用開始年月日

適用開始日は、沖縄県を除いて「地方自治法(昭和22年4月17日法律第67号)」の施行日としている。
沖縄県については、「琉球諸島及び大東諸島に関する日本国とアメリカ合衆国との間の協定(昭和46年6月17日署名)」の発効日としている。

活用例

RDB(OracleとPostgreSQL)への挿入事例

Oracleの場合(Oracle12.2以降)

仮のJSONテーブルを作成しデータを全件挿入する。
(Oracle12.1以前だと「SQLエラー: ORA-00908: NULLキーワードがありません。」が発生する。)

create_json.sql
CREATE TABLE TEMP_JSON (
    V1 CLOB CONSTRAINT c1 CHECK(v1 IS JSON)
);

ORACLEのCLOBに4000バイトを超えるデータを挿入する場合は、4000バイト未満で区切る必要がある。
面倒なので、元のJSONデータを1行ずつ || TO_CLOB(' ～ ')にしてみた。

insert_json.sql
INSERT INTO TEMP_JSON VALUES(
to_clob('{')
|| to_clob('  "_comment":"JIS X 0401:1973, ISO 3166-2:JP",')

RDBっぽいテーブルを作成する。

create_pref.sql
CREATE TABLE PREF (
    CODE CHAR(2)  NOT NULL,
    NAME VARCHAR2(12),
    KANA VARCHAR2(24)
);

仮のJSONテーブルからINSERTする。

insert_pref.sql
INSERT INTO PREF (CODE, NAME, KANA)
SELECT J.CODE, J.NAME, J.KANA
  FROM TEMP_JSON, 
        JSON_TABLE(V1, '$.prefecture_list[*]'
            COLUMNS(CODE VARCHAR2(2)  PATH '$.code',
                    NAME VARCHAR(300) PATH '$.name',
                    KANA VARCHAR(300) PATH '$.kana_name.full_lower'
            )
        ) as J
;
