Questa pagina descrive la struttura consigliata per scrivere prompt efficaci per gli agenti di dati dell'API Conversational Analytics che si connettono ai dati BigQuery. Questi prompt sono contesti creati che definisci come stringhe utilizzando il parametro system_instruction.
Esempi di componenti chiave delle istruzioni di sistema
Le sezioni seguenti contengono esempi di componenti chiave delle istruzioni di sistema in BigQuery. Queste chiavi includono:

Per le descrizioni di questi componenti chiave, consulta la pagina della documentazione Guida il comportamento dell'agente con il contesto creato.
Descrivere i dati con tables
Il seguente blocco di codice YAML mostra la struttura di base della chiave tables per la tabella bigquery-public-data.thelook_ecommerce.orders:

- fields:
- field:
- name: order_id
- description: The unique identifier for each customer order.
- field:
- name: user_id

- table:
- name: bigquery-public-data.thelook_ecommerce.orders
- measures:
- measure:
- name: profit
- description: Raw profit (earnings minus cost).
- exp: earnings - cost
- synonyms: gains
Migliorare la precisione con golden_queries
Ad esempio, puoi definire query di riferimento per analisi comuni per i dati nella tabella orders nel seguente modo:
- tables:
- table:
- golden_queries:
- golden_query:
- natural_language_query: How many orders are there?
- sql_query: SELECT COUNT(*) FROM sqlgen-testing.thelook_ecommerce.orders
- golden_query:
- natural_language_query: How many orders were shipped?
- sql_query: >-
SELECT COUNT(*) FROM sqlgen-testing.thelook_ecommerce.orders
WHERE status = 'shipped'
Delineare le attività in più passaggi con golden_action_plans
Ad esempio, puoi definire un piano d'azione per mostrare le suddivisioni degli ordini per fascia d'età e includere dettagli sulla query SQL e sui passaggi relativi alla visualizzazione:
- tables:
- table:
- golden_action_plans:
- golden_action_plan:
- natural_language_query: Show me the number of orders broken down by age group.
- action_plan:
- step: >-
Run a SQL query that joins the table
sqlgen-testing.thelook_ecommerce.orders and
sqlgen-testing.thelook_ecommerce.users to get a
breakdown of order count by age group.
- step: >-
Create a vertical bar plot using the retrieved data,
with one bar per age group.
Definisci i join delle tabelle con relationships
Ad esempio, puoi definire una relazione orders_to_user tra la tabella bigquery-public-data.thelook_ecommerce.orders e la tabella bigquery-public-data.thelook_ecommerce.users nel seguente modo:
- relationships:
- relationship:
- name: orders_to_user
- description: >-
Connects customer order data to user information with the user_id and id fields to allow an aggregated view of sales by customer demographics.
- relationship_type: many-to-one
- join_type: left
- left_table: bigquery-public-data.thelook_ecommerce.orders
- right_table: bigquery-public-data.thelook_ecommerce.users
- relationship_columns:
- left_column: user_id
- right_column: id
Spiegare i termini commerciali con glossaries
Ad esempio, puoi definire termini come stati aziendali comuni e "OMPF" in base al contesto aziendale specifico nel seguente modo:
- glossaries:
- glossary:
- term: complete
- description: Represents an order status where the order has been completed.
- synonyms: 'finish, done, fulfilled'
- glossary:
- term: shipped
- description: Represents an order status where the order has been shipped to the customer.
- glossary:
- term: returned
- description: Represents an order status where the customer has returned the order.
- glossary:
- term: OMPF
- description: Order Management and Product Fulfillment
Includi ulteriori istruzioni con additional_descriptions
Ad esempio, puoi utilizzare il tasto additional_descriptions per fornire informazioni sulla tua organizzazione come segue:
- additional_descriptions:
- text: All the sales data pertains to The Look, a fictitious ecommerce store.
- text: 'Orders can be of three categories: food, clothes, and electronics.'
