datasets_sql

A 🤗 Datasets extension package that provides support for executing arbitrary SQL queries on HF datasets. It uses DuckDB as a SQL engine and follows its query syntax.

Installation

pip install datasets_sql

Quick Start

from datasets import load_dataset, Dataset
from datasets_sql import query

imdb_dset = load_dataset("imdb", split="train")

# Remove the rows where the `text` field has less than 1000 characters
imdb_query_dset1 = query("SELECT text FROM imdb_dset WHERE length(text) > 1000")

# Count the number of rows per label
imdb_query_dset2 = query("SELECT label, COUNT(*) as num_rows FROM imdb_dset GROUP BY label")

# Remove duplicated rows
imdb_query_dset3 = query("SELECT DISTINCT text FROM imdb_dset")

# Get the average length of the `text` field
imdb_query_dset4 = query("SELECT AVG(length(text)) as avg_text_length FROM imdb_dset")

order_customer_dset = Dataset.from_dict({
    "order_id": [10001, 10002, 10003],
    "customer_id": [3, 1, 2],
})

customer_dset = Dataset.from_dict({
    "customer_id": [1, 2, 3],
    "name": ["John", "Jane", "Mary"],
})

# Join two tables
join_query_dset = query(
    "SELECT order_id, name FROM order_customer_dset INNER JOIN customer_dset ON order_customer_dset.customer_id = customer_dset.customer_id"
)

    How to use query function if dataset is a class attribute

    Awesome library!

    This is probably a generic duckdb question but figured I'd ask here first. If I store a reference to a dataset in a class attribute, how do I get query to find my dataset?

    Repro:

    class DatasetQuery:
    
    def __init__(self, dataset_name, split="train"):
        ds = datasets.load_dataset(dataset_name, split="train")
        self.dataset = ds
    
    def query(self, query_str):
        return query(query_str)

dq = DatasetQuery("huggingnft/boredapeyachtclub")
dq.query("select * from ?? limit 10;")

    What do I put in the from clause? I tried ds and self.dataset but neither work. I get ValueError: The datasetdsnot found in the namespace.

  • Be able to stream the results of query

    Be able to stream the results of query

    I'd like to query a large remote dataset (on the hub or elsewhere) and then stream the results of the query so that I don't have to download the entire dataset to my machine.

    For example, you could query diffusiondb for images generated with prompts containing the word "ceo" to visualize biases:

    SELECT * from poloclub/diffusiondb
WHERE contains('prompt', 'ceo')

    This combined with https://github.com/huggingface/datasets-server/issues/398 would open the door for a lot of cool applications of gradio + datasets where users could interactively explore datasets that don't fit on their machines and create spaces without having to download/store large datasets.

    I see that data can be streamed from duckdb with pyarrow: https://duckdb.org/2021/12/03/duck-arrow.html . I wonder if this can be leveraged for this use case.
