Hi! i want to know can we create chatbot using data from multiple source?

and now i want to make the code can answer my question base my database (we want to use to get data from database instead from csv file :frowning: )

You will need to use function calling. Prepare your own API/function that can retrieve data from your database. Then create function that will convert the user query into the format of the API/function call for your database.
