AWS ATHENAでは、テーブル名に数字から始めるとエラーとなる

Last updated at Posted at 2021-12-22

AWS ATHENAで、テーブルを作ろうとしたら、エラーで作成できませんでした。エラーメッセージが意味不明で少しハマったのですが、数字から始まるテーブルは作成できないようです。修正して解決しました。

(参考)ドキュメントに書いてある通りのCREATE文を組んだつもりでした。(CloudFrontからのログからテーブル作成)
https://docs.aws.amazon.com/ja_jp/athena/latest/ug/cloudfront-logs.html

(参考)ハイフンも駄目なようです。

line 1:8: mismatched input 'EXTERNAL'. Expecting: 'OR', 'SCHEMA', 'TABLE', 'VIEW'

以下のCREATE文はエラーになります。
