I've been having issues in storing variables(parameter replacement) into the database in postgresql using flask; below is what i did but it was not executed; what could be the issue

username: 'Pat'
email: 'pat@gmail'
password: 'pat'

values = {"username": username, "email": email, "password": password}
engine.execute("INSERT INTO users (username, email, password) VALUES (:username,    :email, :password)", values)

What I have tried:

username: 'Pat'
   email: 'pat@gmail'
   password: 'pat'

   values = {"username": username, "email": email, "password": password}
   engine.execute("INSERT INTO users (username, email, password) VALUES (:username,    :email, :password)", values)

You're storing passwords in plain text. Don't do that.

Maybe you need to make a connection first, see example here: How to Execute Raw SQL in SQLAlchemy | Tutorial by Chartio[^]

It could also be that your changes are executed but not committed, so you might need to use something like this:

result = db.engine.execute(text("<sql here>").execution_options(autocommit=True))
