I created this dataset using [sqlglot](https://github.com/tobymao/sqlglot) to auto-convert the Spider and Wikisql datasets to Presto syntax, along with running some regex's for additional cleanup.

An example use case is fine-tuning an existing model to respond with Presto/Athena text-to-sql, if it performs well at standard SQL syntax used by the major text to sql training datasets.

Example of fine-tuning using this dataset (in this case for Mystral 7b Instruct):

```
import json
import pandas as pd
from datasets import Dataset

def read_jsonl(file_path):
    data = []
    with open(file_path, 'r', encoding='utf-8') as file:
        for line in file:
            json_data = json.loads(line.strip())
            data.append(json_data)
    return data

# Read the train and validation files
train_data = read_jsonl('training_data/train.jsonl')
valid_data = read_jsonl('training_data/valid.jsonl')

# Convert to pandas DataFrame
train_df = pd.DataFrame(train_data)
valid_df = pd.DataFrame(valid_data)

# Convert DataFrame to Huggingface Dataset
train_dataset = Dataset.from_pandas(train_df)
valid_dataset = Dataset.from_pandas(valid_df)

# Example of processing
# train_texts = [example['text'] for example in train_dataset]
# valid_texts = [example['text'] for example in valid_dataset]

instruct_tune_dataset = {
    "train": train_dataset,
    "test": valid_dataset
}

def create_prompt(sample):
  """
  Update the prompt template:

  """
  bos_token = "<s>"
  original_system_message = "Below is an instruction that describes a task. Write a response that appropriately completes the request."
  system_message = "Write a SQL query or use a function to answer the following question. Use the SQL dialect Presto for AWS Athena."
  question = sample["question"].replace(original_system_message, "").strip()
  response = sample["answer"].strip()
  eos_token = "</s>"

  full_prompt = ""
  full_prompt += bos_token
  full_prompt += "[INST] <<SYS>>" + system_message + "<</SYS>>\n\n"
  full_prompt += question + " [/INST] "
  full_prompt += response
  full_prompt += eos_token

  return full_prompt
