Questo è super coinvolgente. Basandomi sul post del blog “LLMs and SQL” e su un po’ di tentativi ed errori, ho creato questo prompt che contiene una descrizione parziale del database di Discourse:
Prompt database Discourse
Il testo tra i commenti /* Discourse database documentation start */ e /* Discourse database documentation end */ contiene dettagli sul database PostgreSQL dell'applicazione forum Discourse.
Tutte le tabelle e le colonne sono illustrate nelle istruzioni `CREATE TABLE`. Prendi nota delle query di esempio che seguono ciascuna istruzione `CREATE TABLE`. Alcuni dettagli aggiuntivi importanti sono contenuti nei commenti inline (`-- --`) e multiriga (`/* */`). Dopo aver inviato queste informazioni, ti chiederò di scrivere alcune query da eseguire tramite il plugin Discourse Data Explorer. Tutte le tabelle e le colonne necessarie per scrivere queste query si trovano nelle istruzioni `CREATE TABLE` che ti ho inviato.

/*
Nel primo esempio qui sotto, l'utente con id 1 ha messo mi piace (action_type: 1) al post con id 11100. Poiché l'utente con id 1 ha eseguito l'azione, 1 è impostato come valore della colonna acting_user_id. Poiché la voce registra che questo utente ha eseguito un'azione di "mi piace", il suo user id (1) è impostato anche nella colonna user_id della voce.
Ecco un esempio di query che restituirebbe il numero di volte in cui l'utente con id: 1 ha messo mi piace ai post di altri utenti: `SELECT COUNT(user_id) AS number_of_likes_given FROM user_actions WHERE action_type = 1 AND user_id = 1;`
Nel secondo esempio qui sotto, l'utente con id 121 ha ricevuto un mi piace sul suo post (id 11100) da un altro utente (action_type: 2). La colonna user_id della voce è impostata su 121 perché è l'id dell'utente che ha ricevuto il mi piace sul post. La colonna acting_user_id della voce è impostata su 1 perché è l'utente che ha messo mi piace al post.
Ecco un esempio di query che restituisce il numero di volte in cui l'utente con id 121 ha ricevuto mi piace sui suoi post da altri utenti: `SELECT COUNT(user_id) AS number_of_likes_received FROM user_actions WHERE action_type = 2 AND user_id = 121;`
Ecco un esempio di query che restituisce il numero di volte in cui l'utente con id 121 ha ricevuto mi piace sui suoi post dall'utente con id: 1: `SELECT COUNT(user_id) AS number_of_likes_received_from_user_1 FROM user_actions WHERE action_type = 2 AND user_id = 121 AND acting_user_id = 1;`
Nel terzo esempio, l'utente con id 121 è stato menzionato (action_type: 7) nel post (id 11101) dall'utente con id 2. La colonna user_id della voce è impostata su 121 perché è l'id dell'utente che è stato menzionato. La colonna acting_user_id della voce è impostata su 2 perché è l'id dell'utente che ha creato la menzione.
Ecco un esempio che restituisce il numero di volte in cui l'utente con id 121 è stato menzionato da qualsiasi utente: `SELECT COUNT(user_id) AS number_of_mentions_received FROM user_actions WHERE action_type = 7 AND user_id = 121;`
Ecco un esempio di query che restituisce il numero di volte in cui l'utente con id 121 è stato menzionato dall'utente con id 2: `SELECT COUNT(user_id) AS number_of_mentions_received_from_user_2 FROM user_actions WHERE action_type = 7 AND user_id = 121 AND acting_user_id = 2;`
Ecco un esempio di query che restituisce il numero di volte in cui l'utente con id 121 è stato menzionato nel topic con id 7282: `SELECT COUNT(user_id) AS number_of_mentions_received_in_topic FROM user_actions WHERE action_type = 7 AND user_id = 121 AND target_topic_id = 7282;`

/* Fine documentazione database Discourse */
Copre le tabelle users, groups, group_users, posts, topics, categories, tags, topic_tags, user_actions, polls, poll_options e poll_votes. Al momento è di 1150 token, quindi dovrebbe poter raddoppiare le sue dimensioni senza causare problemi. Nota che se lo copi in un input chat di ChatGPT, dovrai incollarlo in due input separati - il limite di caratteri di un input chat è inferiore al limite di token per una sessione chat.
Ho aggiunto commenti piuttosto dettagliati sopra le query di esempio user_actions. Con quegli esempi, ChatGPT sta facendo un buon lavoro nel rispondere a domande sui mi piace dati, mi piace ricevuti, ecc. In precedenza aveva avuto difficoltà con questo. Sospetto che ci siano alcune tabelle che richiederebbero un approccio simile.
Dopo aver inviato la documentazione, i seguenti prompt sono utili:
Esempi di prompt
Quando ti chiedo di iniziare una query con una ‘CTE query period’, voglio che la query inizi esattamente con questo SQL (incluso il commento):
--[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
)
Il plugin Data Explorer consente di aggiungere parametri alle sue query. I parametri utilizzati nelle query devono apparire in un commento in cima alla query in questa forma:
--[params]
--param_type :param_name
I tipi di parametro disponibili sono:
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
Ecco un esempio:
--[params]
-- string :action_type
È possibile fornire un valore predefinito opzionale per un parametro. Per esempio:
--[params]
--string :action_type = like
Ho creato il prompt “CTE query_period” perché se non avessi detto specificamente a ChatGPT come creare la CTE query_period, proponeva tutte sorts di soluzioni, alcune migliori di altre. Con il prompt, aggiunge il codice esatto che gli do, poi costruisce query sopra di esso senza alcun problema. Curiosamente, quando ho provato ad aggiungere dettagli su come creare una “CTE query period” alla documentazione iniziale che ho inviato a ChatGPT, ignorava semplicemente le istruzioni. Per qualche motivo, inviarlo come prompt separato fa la differenza.
I prompt che descrivono come Discourse “elimina in modo soft” i topics e i post sono anche utili. Dopo aver fatto sapere a ChatGPT della necessità di verificare che deleted_at IS NOT NULL per le query relative a topics e post, applica costantemente questa regola a tutte le query.
Dire a ChatGPT di omettere il punto e virgola alla fine delle query è quasi disperato. Si ricorda per un paio di query, poi torna ad aggiungere il punto e virgola. Sembra un dettaglio minore.
La mia speranza iniziale di ottenere una query perfetta da una domanda in linguaggio naturale era un po’ ambiziosa. Fa errori, e anche io. Almeno nel breve termine, penso che il modo migliore per integrare ChatGPT con il plugin Data Explorer sarebbe quello di iniziare una PM con ChatGPT. Una descrizione di base del database potrebbe essere inviata quando la PM viene creata. Poi una selezione di prompt potrebbe essere resa disponibile tramite l’interfaccia utente. Per esempio, un prompt per parametrizzare una query, o un prompt per aggiungere dettagli su una tabella poco usata.
Il mio sospetto è che questo potrebbe essere molto utile a qualcuno che conosce un po’ di SQL, ma forse potrebbe anche essere implementato in un modo che aiuterebbe le persone nuove a SQL a prendere confidenza molto più velocemente di quanto farebbero da sole. Ho imparato questo meraviglioso trucco oggi:
WITH post_type_mapping AS (
SELECT 'regular' AS type, 1 AS post_type
UNION ALL
SELECT 'moderator_action' AS type, 2 AS post_type
UNION ALL
SELECT 'small_action' AS type, 3 AS post_type
UNION ALL
SELECT 'whisper' AS type, 4 AS post_type
)
...
JOIN post_type_mapping m ON :post_type = m.type
WHERE p.post_type = m.post_type
