MindsDB and SQL Alchemy

SQL Alchemy is a Python SQL toolkit, that provides object-relational mapping features for the Python programming language.

SQL Alchemy facilitates working with databases and Python. You can download it here or run a pip install sqlalchemy.

You can consider an option to interact with MindsDB directly from MySQL CLI or Postgres CLI.

​
How to Connect

Please follow the instructions below to connect your MindsDB to SQL Alchemy.

  • Local MindsDB

  • MindsDB Cloud

  • MindsDB Pro

You can use the Python code below to connect your MindsDB database to SQL Alchemy.

Make sure you have the pymysql module installed before executing the Python code. To install it, run the pip install pymysql command.

from sqlalchemy import create_engine

user = 'mindsdb'
password = ''
host = '127.0.0.1'
port = 47335
database = ''

def get_connection():
    return create_engine(
        url="mysql+pymysql://{0}:{1}@{2}:{3}/{4}".format(user, password, host, port, database)
    )

if __name__ == '__main__':
    try:
        engine = get_connection()
        engine.connect()
        print(f"Connection to the {host} for user {user} created successfully.")
    except Exception as ex:
        print("Connection could not be made due to the following error: \n", ex)

Please note that we use the following connection details:

  • Username is mindsdb
  • Password is left empty
  • Host is 127.0.0.1
  • Port is 47335
  • Database name is left empty

To create a database connection, execute the code above. On success, the following output is expected:

Connection to the 127.0.0.1 for user mindsdb created successfully.

The Sqlachemy create_engine is lazy. This implies any human error when entering the connection details would be undetectable until an action becomes necessary, such as when calling the execute method to execute SQL commands.
