Create query construction prompt.

Parameters:
  • document_contents (str) – The contents of the document to be queried.

  • attribute_info (Sequence[AttributeInfo | dict]) – A list of AttributeInfo objects describing the attributes of the document.

  • examples (Sequence | None) – Optional list of examples to use for the chain.

  • allowed_comparators (Sequence[Comparator]) – Sequence of allowed comparators.

  • allowed_operators (Sequence[Operator]) – Sequence of allowed operators.

  • enable_limit (bool) – Whether to enable the limit operator. Defaults to False.

  • schema_prompt (BasePromptTemplate | None) – Prompt for describing query schema. Should have string input variables allowed_comparators and allowed_operators.

  • kwargs (Any) – Additional named params to pass to FewShotPromptTemplate init.

Returns:

A prompt template that can be used to construct queries.

Return type:

BasePromptTemplate
