# `nnul/sqlchat`: A Conversational AI for SQL Generation
|
| 2 |
|
| 3 |
+
This repository contains `sqlchat`, a powerful and efficient language model designed specifically for **Text-to-SQL** tasks. It can understand natural language questions and database schemas to generate accurate SQL queries, including complex statements for creating and managing tables (Data Definition Language).
|
| 4 |
|
| 5 |
+
This model is provided as a standalone 4-bit quantized model, optimized for easy deployment and high-performance, low-resource inference. It was built using the [Unsloth](https://github.com/unslothai/unsloth) library to ensure maximum speed and memory efficiency.
|
| 6 |
|
| 7 |
+
## Model Capabilities
|
| 8 |
|
| 9 |
+
* **Natural Language to SQL:** Translates complex English questions into executable SQL queries.
|
| 10 |
+
* **Schema-Aware:** Understands `CREATE TABLE` contexts provided in the prompt to generate relevant queries.
|
| 11 |
+
* **DDL Generation:** Capable of generating `CREATE TABLE` statements, including constraints like `PRIMARY KEY` and `FOREIGN KEY` relationships.
|
| 12 |
+
* **Complex Query Logic:** Successfully handles `JOIN`s, aggregations (`COUNT`, `MAX`), and sorting (`ORDER BY ... LIMIT`).
