How to execute raw SQL in Flask-SQLAlchemy app

Question

How do you execute raw SQL in SQLAlchemy?

I have a python web app that runs on flask and interfaces to the database through SQLAlchemy.

I need a way to run the raw SQL. The query involves multiple table joins along with Inline views.

I've tried:

connection = db.session.connection()

connection.execute( <sql here> )

But I keep getting gateway errors.

Try using as follows:

result = db.engine.execute("<sql here>")

Otherwise, you can use this 

from sqlalchemy import text

sql = text('select name from penguins')

result = db.engine.execute(sql)

names = [row[0] for row in result]

print names
