Gengliang Wang	f9f08c4b69	Add documentation for Databricks integration (#5013 ) # Add documentation for Databricks integration This is a follow-up of https://github.com/hwchase17/langchain/pull/4702 It documents the details of how to integrate Databricks using langchain. It also provides examples in a notebook. ## Who can review? @dev2049 @hwchase17 since you are aware of the context. We will promote the integration after this doc is ready. Thanks in advance!	1 year ago

Gengliang Wang	bf5a3c6dec	Support Databricks in SQLDatabase (#4702 ) This PR adds support for Databricks runtime and Databricks SQL by using [Databricks SQL Connector for Python](https://docs.databricks.com/dev-tools/python-sql-connector.html). As a cloud data platform, accessing Databricks requires a URL as follows `databricks://token:{api_token}@{hostname}?http_path={http_path}&catalog={catalog}&schema={schema}`. The URL is complicated and it may take users a while to figure it out. Since the fields `api_token`/`hostname`/`http_path` fields are known in the Databricks notebook, I am proposing a new method `from_databricks` to simplify the connection to Databricks. ## In Databricks Notebook After changes, Databricks users only need to specify the `catalog` and `schema` field when using langchain. <img width="881" alt="image" src="https://github.com/hwchase17/langchain/assets/1097932/984b4c57-4c2d-489d-b060-5f4918ef2f37"> ## In Jupyter Notebook The method can be used on the local setup as well: <img width="678" alt="image" src="https://github.com/hwchase17/langchain/assets/1097932/142e8805-a6ef-4919-b28e-9796ca31ef19">	1 year ago

William FH	629fda3957	Use JSON rather than JSON5 (#2520 ) Evaluation so far has shown that agents do a reasonable job of emitting `json` blocks as arguments when cued (instead of typescript), and `json` permits the `strict=False` flag to permit control characters, which are likely to appear in the response in particular. This PR makes this change to the request and response synthesizer chains, and fixes the temperature to the OpenAI agent in the eval notebook. It also adds a `raise_error = False` flag in the notebook to facilitate debugging	2 years ago
William FH	f8e4048cd8	Add an Example Evaluation Notebook for the API Chain (#2516 ) Taking the Klarna API as an example, uses evaluation chain's to judge the quality of the request and response synthesizers based on a small set of curated queries. Also updates intermediate steps for chain to emit a dict so each step can be keyed for lookup ![image](https://user-images.githubusercontent.com/13333726/230505771-5cdb4de4-6fe7-4f54-b944-f29d438fa42c.png)	2 years ago

Also, we could have better support for Swagger 2.0 specs and OpenAPI 3.0.3 (can use the same lib for the latter) recommend offline conversion for now.	2 years ago

Jon Luo	0a1b1806e9	sql: do not hard code the LIMIT clause in the table_info section (#1563 ) Seeing a lot of issues in Discord in which the LLM is not using the correct LIMIT clause for different SQL dialects. ie, it's using `LIMIT` for mssql instead of `TOP`, or instead of `ROWNUM` for Oracle, etc. I think this could be due to us specifying the LIMIT statement in the example rows portion of `table_info`. So the LLM is seeing the `LIMIT` statement used in the prompt. Since we can't specify each dialect's method here, I think it's fine to just replace the `SELECT... LIMIT 3;` statement with `3 rows from table_name table:`, and wrap everything in a block comment directly following the `CREATE` statement. The Rajkumar et al paper wrapped the example rows and `SELECT` statement in a block comment as well anyway. Thoughts @fpingham?	2 years ago

Jon Luo	5bf8772f26	add option to use user-defined SQL table info (#1347 ) Currently, table information is gathered through SQLAlchemy as complete table DDL and a user-selected number of sample rows from each table. This PR adds the option to use user-defined table information instead of automatically collecting it. This will use the provided table information and fall back to the automatic gathering for tables that the user didn't provide information for. Off the top of my head, there are a few cases where this can be quite useful: - The first n rows of a table are uninformative, or very similar to one another. In this case, hand-crafting example rows for a table such that they provide the good, diverse information can be very helpful. Another approach we can think about later is getting a random sample of n rows instead of the first n rows, but there are some performance considerations that need to be taken there. Even so, hand-crafting the sample rows is useful and can guarantee the model sees informative data. - The user doesn't want every column to be available to the model. This is not an elegant way to fulfill this specific need since the user would have to provide the table definition instead of a simple list of columns to include or ignore, but it does work for this purpose. - For the developers, this makes it a lot easier to compare/benchmark the performance of different prompting structures for providing table information in the prompt. These are cases I've run into myself (particularly cases 1 and 3) and I've found these changes useful. Personally, I keep custom table info for a few tables in a yaml file for versioning and easy loading. Definitely open to other opinions/approaches though!	2 years ago

Harrison Chase	ec727bf166	Align table info (#999 ) (#1034 ) Currently the chain is getting the column names and types on the one side and the example rows on the other. It is easier for the llm to read the table information if the column name and examples are shown together so that it can easily understand to which columns do the examples refer to. For an instantiation of this, please refer to the changes in the `sqlite.ipynb` notebook. Also changed `eval` for `ast.literal_eval` when interpreting the results from the sample row query since it is a better practice. --------- Co-authored-by: Francisco Ingham <> --------- Co-authored-by: Francisco Ingham <fpingham@gmail.com>	2 years ago
