SQL with LLM

sqllm - SQL with LLM functions

With this library, you can use LLM to perform queries on your data. The only LLM function you need to learn is the "AI" function.

• AI(prompt: str) -> str: Returns text generated by GPT given the prompt.

Thanks to the cache, if the AI function is called repeatedly with the same arguments, the LLM is called only the first time.

import os
import sqllm

os.environ["OPENAI_API_KEY"] = "your-api-key"

# query over DB
conn  # any DB connection you have (passed into pd.read_sql)
sqllm.query(
    conn,
    """
    SELECT
        AI('Classify the sentiment expressed in the following text. \ntext:' || review)
    FROM
        reviews
    """
)

# query on pandas dataframe
df  # any dataframe
sqll.query_df(
    df,
    """
    SELECT
        AI('Classify the sentiment expressed in the following text. \ntext:' || review)
    FROM
        df
    """
)

In addition, your own Python functions can also be executed in SQL. This allows you to integrate various text processing with LLM into SQL.

from functools import lru_cache
from openai import OpenAI
import sqllm


# To reduce the number of LLM calls, the use of lru_cache is recommended.
@lru_cache
def sentiment(src: str) -> str:
    client = OpenAI(api_key="your-api-key")
    chat_completion = client.chat.completions.create(
        messages=[
            {
                "role": "system",
                "content": "Classify the sentiment expressed in the following text. The output should be one of 'positive', 'negative' or 'neutral'."
            },
            {
                "role": "user",
                "content": src
            }
        ],
        model="gpt-3.5-turbo",
    )
    return chat_completion.choices[0].message.content


sqllm.query(
    conn,
    """
    SELECT
        sentiment(review) as sentiment
    FROM
        reviews
    """,
    [sentiment]
)

The sqllm.functions module contains several example implementations of user-defined functions. This implementation can be used out of the box.

import sqllm
from sqllm.functions import sentiment, summarize


sqllm.query(
    conn,
    """
    SELECT
        sentiment(review) as sentiment,
        summarize(review) as review_summary
    FROM
        reviews
    """,
    [sentiment, summarize]
)

Important notes

This library is not recommended for execution on large data.
