これは非常に中毒性があります。「LLM と SQL」に関するブログ投稿と、少しの試行錯誤を基に、Discourse データベースの部分的な説明を含むこのプロンプトを作成しました：
Discourse データベースのプロンプト
/* Discourse database documentation start */ と /* Discourse database documentation end */ コメントの間のテキストには、Discourse フォーラムアプリケーションの PostgreSQL データベースに関する詳細が含まれています。
すべてのテーブルと列は `CREATE TABLE` 文で定義されています。各 `CREATE TABLE` 文に続くサンプルクエリにも注意してください。いくつかの追加の重要な詳細は、
インライン (`-- --`) および複数行 (`/* */`) コメントに含まれています。この情報を送信した後、Discourse Data Explorer プラグインで実行するいくつかのクエリを作成するように依頼します。これらのクエリを作成するために必要なすべてのテーブルと列は、
私が送信した `CREATE TABLE` 文に含まれています。

/* Discourse database documentation end */
これは users、groups、group_users、posts、topics、categories、tags、topic_tags、user_actions、polls、poll_options、および poll_votes テーブルをカバーしています。現在は 1150 トークンなので、問題を引き起こすことなくサイズを2倍にできるはずです。なお、これを ChatGPT のチャット入力にコピーする場合、2つの別々の入力に貼り付ける必要があります。チャット入力の文字制限は、チャットセッションのトークン制限よりも少ないためです。
例の user_actions クエリの前にかなり詳細なコメントを追加しました。これらの例のおかげで、ChatGPT は「いいね」を与えた回数や「いいね」を受けた回数などに関する質問にうまく答えています。以前はそこでの処理に苦労していました。同様のアプローチが必要なテーブルがいくつかあると思われます。
ドキュメントを送信した後、以下のプロンプトが役立ちます。
プロンプトの例
「クエリ期間 CTE でクエリを開始してください」と尋ねた場合、クエリは以下の SQL（コメントを含む）から正確に開始されるようにしてください：
--[params]
-- string :query_interval = 1 week
-- date :start_date
-- date :end_date
WITH query_periods AS (
SELECT
generate_series(:start_date, :end_date, :query_interval::interval)::date AS period_start,
(generate_series(:start_date, :end_date, :query_interval::interval)::date + :query_interval::interval - INTERVAL '1 DAY')::date AS period_end
)
Data Explorer プラグインはクエリにパラメータを追加できるようにしています。クエリで使用されるパラメータは、この形式でクエリの上部のコメントに表示する必要があります：
--[params]
--param_type :param_name
使用可能なパラメータタイプは：
int、bigint、boolean、string、date、time、datetime、double、user_id、post_id、topic_id、category_id、group_id、badge_id、int_list、string_list、user_listです。
以下は例です：
--[params]
-- string :action_type
パラメータにオプションのデフォルト値を指定できます。例えば：
--[params]
--string :action_type = like
「クエリ期間 CTE」プロンプトを作成したのは、ChatGPT にクエリ期間 CTE の作成方法を具体的に指示しなかった場合、種々のソリューション（良いものも悪いものも）を提示してくるためです。プロンプトを使用すると、私が指定した正確なコードを追加し、その後問題なくその上にクエリを構築します。興味深いことに、ChatGPT に送信した初期ドキュメントに「クエリ期間 CTE」の作成方法に関する詳細を追加しようとした際、ChatGPT はその指示を無視しました。なぜか、別々のプロンプトとして送信すると違いが生まれます。
Discourse がトピックや投稿を「論理的に削除（soft delete）」する方法を説明するプロンプトも役立ちます。トピックや投稿に関連するクエリでは deleted_at IS NOT NULL をチェックする必要があることを ChatGPT に知らせた後、一貫してすべてのクエリにそれを適用しています。
ChatGPT にクエリの末尾からセミコロンを省略するように指示するのは、ほぼ不可能です。数回クエリでは覚えていますが、その後すぐにセミコロンを追加するよう戻ります。これは些細な詳細のようです。
自然言語の質問から完璧なクエリが返ってくるという私の当初の期待は、少し野心的でした。ChatGPT も私もミスをするものです。少なくとも短期的には、ChatGPT を Data Explorer プラグインと統合する最善の方法は、ChatGPT との PM（プライベートメッセージ）を開始することだと思われます。PM が作成された際にデータベースの基本的な説明を送信できます。その後、UI を介してプロンプトの選択を可能にします。例えば、クエリのパラメータ化用のプロンプトや、 rarely used table（あまり使用されないテーブル）に関する詳細を追加するためのプロンプトなどです。
これは、SQL に少し詳しい人にとって非常に役立つ可能性があると思われますが、SQL に慣れていない人でも、自力で学ぶよりもはるかに早く習得できるように実装することも可能かもしれません。今日、この素晴らしいトリックを学びました：
