## Model Details

This model can be used to identify relevant SQL tables for query to SQL translation.

The model was finetuned using a curated dataset of SQL table definitions and corresponding natural language queries.
The script used for finetuning: [Flag Embeddings](https://github.com/FlagOpen/FlagEmbedding/blob/master/examples/unified_finetune/unified_finetune_bge-m3_exmaple.sh)

## Usage

### Direct Usage (Sentence Transformers)

First install the Sentence Transformers library:

```bash
pip install -U sentence-transformers
```

Then you can load this model and run inference.
```python
from sentence_transformers import SentenceTransformer

# Download from the 🤗 Hub
model = SentenceTransformer("sentence_transformers_model_id")
# Run inference
sentences = [
    'What is the total biomass of fish in farms with a water temperature above 25 degrees Celsius?',
    'CREATE TABLE Farm (FarmID INT, FarmName VARCHAR(50), WaterTemperature DECIMAL, Biomass DECIMAL)',
    'CREATE TABLE Locations (id INT PRIMARY KEY, name VARCHAR(50), region VARCHAR(50), depth INT)',
]
embeddings = model.encode(sentences)
print(embeddings.shape)
# [3, 1024]

# Get the similarity scores for the embeddings
similarities = model.similarity(embeddings, embeddings)
print(similarities.shape)
# [3, 3]
```
