SQLite mcp server: ALTER TABLE personal_data ADD COLUMN job_title TEXT doesn't add column to table.

[peter-chenqing]

environment: os: windows 11, python: python3.12.7, agent framework: autogen0.4.7
hereafter is my code:

import os
import asyncio
from dotenv import load_dotenv

from autogen_agentchat.agents import AssistantAgent
from autogen_ext.models.openai import OpenAIChatCompletionClient
from autogen_ext.tools.mcp import StdioServerParams, mcp_server_tools
from autogen_core.models import ModelFamily
load_dotenv()

async def main()->None:

sqlite_mcp_server=StdioServerParams(command='docker',
                                    args=[
                                        "run",
                                        "--rm",
                                        "-i",
                                        "-v",
                                        ".:/mcp",
                                        "mcp/sqlite",
                                        "--db-path",
                                        "/mcp/personal.db"
                                        ]) 
tools=await mcp_server_tools(sqlite_mcp_server)

# Create a model client.
model_client=OpenAIChatCompletionClient(
    api_key=os.getenv('deepseek_API_Key'),
    model=os.getenv('deepseek_model'),
    base_url=os.getenv('deepseek_base_url'),
    model_info={
        "vision":False,
        "function_calling":True,
        "json_output":True,
        "family":ModelFamily.UNKNOWN,
    },
    )
# Create an agent that can use  tool.
agent=AssistantAgent(
    name='sqlitedata',
    model_client=model_client,
    tools=tools,
    reflect_on_tool_use=True,
    )

# Start the agent .
result=await agent.run(task="Add a cloumn named 'job_title' and assign a random job title value to each guy in the personal_data.")
print(result.messages[-1].content)

if name=='main':
asyncio.run(main())

when I run this code, the result is 'TERMINATE', it shows that the code has been executed successful. but when I check the personal_data table, there is not column named 'job_title.' however, when I set the task='whose salary is lowest in the personal_data table', the code can give me a right answer.
