# `db`

Here's the reference for all database session utilities, transaction helpers, and locking functions.

You can import them directly from `fastapi_toolsets.db`:

```python
from fastapi_toolsets.db import (
    LockMode,
    create_db_dependency,
    create_db_context,
    get_transaction,
    lock_tables,
    wait_for_row_change,
)
```
