Attempts to write to the database will fail with an error. 29 | 30 | With the [LLM Python API](https://llm.datasette.io/en/stable/python-api.html): 31 | 32 | ```python 33 | import llm 34 | from llm_tools_sqlite import SQLite 35 | 36 | model = llm.get_model("gpt-4.1-mini") 37 | 38 | result = model.chain( 39 | "Show me the three most interesting looking tables", 40 | tools=[SQLite("content.db")] 41 | ) 42 | for s in result: 43 | print(s, end="", flush=True) 44 | ``` 45 | 46 | ## Development 47 | 48 | To set up this plugin locally, first checkout the code.
