I am having issues with connecting Amazon AWS MySQL with SQLAlchemy. According to the instruction, I have connected.

app.config['SQLALCHEMY_DATABASE_URI'] = 'mysql://<user>:<password>@<host>/<dbname>

But there is an error:

I am using Python3.7 version. Even according to the stackoverflow, I have installed pymysql, but still facing the problem.

Thank you for your reply.

If you use the PyMySQL client to connect to MySQL, your SQLAlchemy connection string needs to start with

 mysql+pymysql://

instead of mysql://.

If you connect with mysql:// then you will need to install the MySQLdb library as shown in the Traceback.

Python: 'ModuleNotFoundError' when trying to import module from , SECOND, for the " ModuleNotFoundError: No module named 'Soft' " error caused by from Mans import man1 in man1test.py, the documented  Some of the modules like pandas, etc., use openpyxl if you are working with Excel file functionalities. If you run your Python program and got this error “ModuleNotFoundError: No module named ‘openpyxl'”, it means that openpyxl module is not installed. An example stack trace would be as shown below.

Step 1 If you want to use MySQLDB you need to use one of the following commands. Which one depends on what OS and software you have and use.

easy_install mysql-python (mix os)

pip install mysql-python (mix os/ python 2)

pip install mysqlclient (mix os/ python 3)

apt-get install python-mysqldb (Linux Ubuntu, ...)

cd /usr/ports/databases/py-MySQLdb && make install clean (FreeBSD)

yum install MySQL-python (Linux Fedora, CentOS ...)

For Windows, see this answer: Install mysql-python (Windows)

Step 2:

  1. Create Engine

engine = create_engine('mysql+mysqldb://...', pool_recycle=3600)

use the create_engine.pool_recycle option which ensures that a connection will be discarded and replaced with a new one if it has been present in the pool for a fixed number of seconds:

  1. Create Connection object

conn = engine.connect()

  1. Execute SQL queries

conn.execute("SELECT * From table;")

  • Solves the problem, but would someone add some explanation of what's happening? (I would ask a question; but I'm not sure yet what the question would be.)
  • Above issues has been solved: import pymysql pymysql.install_as_MySQLdb() Thank you all for suggestion. Nothing to change in other
