I get the sense that we are a long, long way from this being usable with schemas you'd find in the real world.

Since there are many things that are done and work very well in colab but when you take them to VSC they don't. Please can you implement in VSC. Thanks. By the way, excellent the way you develop the themes inside the video!!!

Good queston.Maybe try regex ? eg matches = re.findall(Action) from the response, - maybe if anyone else reads this they can suggest another way?

Hi there- thanks for this video!
Is it possible to use retrievers and condensers with the sql connector? I know it the pdf document loaders you’re able to find only the relevant text using a retriever, condense it to reduce token count and send that as context to the LLM. Perhaps that would save on cost?

Also, I’m guessing that using memory to store indexes of your data in something like pinecone is useless with a database because data is always changing- is that correct?

Thank you for this video. One question though, does this mean the data is being sent to openai for it to process, I mean from privacy perspective this is really concerning

[sumeetracharla]

Can you please tell me how to resolve the prompt length issue

[usoppgostoso]

The database was hosted on your device and you ran the code on Colab or something like that? It’d be great if it connects with no issue to a local database.

Like to ask why some logic is in python file and some in Jupyter notebook?

[zzz-qews]

the default schema is the public, if i want to connect to my custom schema like 'my_schema', what should i do ? thanks a lot!

[pradyumnjain]

will this work for large amount of data as well? How will it take in account such a big context?

[minurapunchihewa]

Great video!
I have a couple of questions, if that's OK.
1. What are the versions of langchain and openai that you are using? I am trying to run the SQL Agent on a SQLite database and I keep running into this error,
AuthenticationError: <empty message>

2. At the beginning of the video you mentioned that the SQL Agent uses up a lot OpenAI credits. Do you have an approximate value for how many credits it uses up? Is it definitely more than one request per run?

I got this error ValueError: Invalid header value b'Bearer API

[SMCGPRA]

How use open-source LLM s like private gpt gpt4all vicuna

[capeandcode]

How can I get only the SQL query and not the summarized response that it provides?

[nishantkumar-lwce]

Can it generate the visualizations as well?
