I am trying to extract data from a local Postgres database using a llm API. The query is generated correctly and I am able to extract the query correctly using MS autogen agents. The problem is when it comes to execution. The executing agent does not execute the query. It only shows simulated results. I have included the execution query in the function map.

Connection to the database is established, and table definitions are derived to form the prompt.

This is the code executioner.

    senior_data_analyst  = autogen.AssistantAgent(
        name="Senior Data Analyst",
        system_message=senior_data_analyst_prompt,
        llm_config=llm_config,
        code_execution_config=False,   # Prevents arbitrary code execution, except code in the function map.
        human_input_mode="NEVER",    # asks for a human input each time a message is received.
        is_termination_msg=is_termination_msg,
        function_map=function_map,
    )

The function map is as follows:

   function_map = {
        "run_sql": db.run_sql,
    }

Here is the db.run_sql function:

def run_sql(self, sql) -> str:
    print("In run_sql: NO ERRORS IN DB.")
    self.cur.execute(sql)
    columns = [desc[0] for desc in self.cur.description]
    res = self.cur.fetchall()
    list_of_dicts = [dict(zip(columns, row)) for row in res]
    json_result = json.dumps(list_of_dicts, indent=4, default=self.datetime_handler)
    return json_result

I downloaded autogen using the command, about a week ago. Not sure if it is a version issue.

pip install autogen-agentchat~=0.2

I have tried changing my prompt but didn't get any results. Only thing that changes is the dummy output. I even tried a to print something in the run_sql function.

senior_data_analyst_prompt = "Senior_Data_Analyst. You follow approved plan. EXECUTE FUNCTION run_sql, show the FUNCTION EXECUTED, DISPLAY RESULTS ONLY. SEND QUERY AND Generated response to the product manager for final review."

But it seems that the problems is the db.run_sql() function is not called by the agent. Code runs normally, without errors. How can I make this agent to call the run_sql() and to pass the derived SQL statement to it?

run_sql_config = {
    "use_cache":False, # to run each new session from the beginning.
    #"cache_seed": 42,  # to get consistent result for same input.
    "config_list":config_list, 
    "temperature": 0,
    "timeout": 120,
    "functions": [
         {
              "name":"run_sql",
              "description": "Run a SQL query against the Postgres database.",
              "parameters":{
                   "type":"object",
                   "properties":{
                        "sql":{
                             "type":"string",
                             "description":"The SQL query to RUN."
                        }
                   },
                   "required":["sql"],
              },
         },
    ],
}

I have added the config_list as well. Below is the output result, with dummy data. The output is as single SQL query, complex but perfectly valid. I checked with pgadmin. Only thing is results are completely different. Print() within run_sql is not used.

FUNCTION EXECUTED

The SQL function executed is a complex query that retrieves data from the stolen_vehicles table in the new_zealand schema. The query is divided into four Common Table Expressions (CTEs):

1. silver_vehicles: This CTE filters the stolen_vehicles table to include only vehicles with a color of 'Silver' and a date stolen in the year 2022. It also joins the locations table to retrieve the region for each vehicle.
2. vehicle_type_count: This CTE groups the silver_vehicles CTE by vehicle type and counts the number of vehicles in each group.
3. vehicle_model_count: This CTE groups the silver_vehicles CTE by vehicle model and counts the number of vehicles in each group.
4. total_vehicle_count: This CTE counts the total number of vehicles in the silver_vehicles CTE.

The main query joins the silver_vehicles CTE with the vehicle_type_count and vehicle_model_count CTEs to retrieve the count of vehicles for each type and model. It also joins the total_vehicle_count CTE to retrieve the total count of vehicles. The query calculates the percentage of vehicles for each type and model relative to the total count.

DISPLAY RESULTS

Here is a sample output of the query in a table format:
