TDにアップロードしたいが、Embulkのymlファイルがないので作るとき

Last updated at Posted at 2020-12-22

information_schemaからこうやってやるメモっす

既にTDのTableに入ってるんだけど、embulkのファイルがないーこれをコネクターで取りたい―とかWFで取りたい―とかの場合
(今回は同一ファイルのIF元が変わるーんだけどembulkのymlが手元にない。先方は現行保障してs3にputするのでwfで取得してね。って言われたパターン)

information_schemaからordinal_position順に書き出せば、すぐにembulkのymlにできそう。(guessできないときの話)

SELECT
    ordinal_position,
    column_name,
    data_type,
    '  - {name: '||column_name||', type: '||case data_type
      when 'varchar' then 'string'
      when 'bigint' then 'long'
      else data_type
    end||'}' as col
FROM
    information_schema.columns
WHERE
    table_schema = '(DB_NAME)'  -- DB名
AND
    table_name = '(Table_NAME)'  -- テーブル名
AND
    column_name != 'time'  -- timeカラムは除外
order by ordinal_position -- 入ってる順番にソート
