SQL查询引擎

Default query for GPTSQLStructStoreIndex.

class llama_index.indices.struct_store.sql_query.GPTNLStructStoreQueryEngine(index: GPTSQLStructStoreIndex, text_to_sql_prompt: Optional[Prompt] = None, context_query_kwargs: Optional[dict] = None, synthesize_response: bool = True, response_synthesis_prompt: Optional[Prompt] = None, **kwargs: Any)

GPT natural language query engine over a structured database.

Given a natural language query, we will extract the query to SQL. Runs raw SQL over a GPTSQLStructStoreIndex. No LLM calls are made during the SQL execution. NOTE: this query cannot work with composed indices - if the index contains subindices, those subindices will not be queried.

参数

  • index (GPTSQLStructStoreIndex) -- A GPT SQL Struct Store Index

  • text_to_sql_prompt (Optional[Prompt]) -- A Text to SQL Prompt to use for the query. Defaults to DEFAULT_TEXT_TO_SQL_PROMPT.

  • context_query_kwargs (Optional[dict]) -- Keyword arguments for the context query. Defaults to {}.

  • synthesize_response (bool) -- Whether to synthesize a response from the query results. Defaults to True.

  • response_synthesis_prompt (Optional[Prompt]) -- A Response Synthesis Prompt to use for the query. Defaults to DEFAULT_RESPONSE_SYNTHESIS_PROMPT.
