But the second statement will create two rows since a list of two dictionaries was passed. The first execute statement will create just one row because a single dictionary was passed.
execute ( text ( "INSERT INTO example (name) VALUES (:name)" ), ]) connection. We need to call nnect() to get a connection, and because the connect method is defined with a context manager, we can use a with statement to work with the connection. Since the engine manages connections, you need to ask the engine for a connection before you can send statements over to the database.
To start sending queries over, you'll need to create a connection object. Now that we have our engine object working let's use it to send raw SQL statements to the database and receive the results in return.
#INSERT INTO MYSQL FLASK HOW TO#
This article covers how to use it to send raw queries to your database and how to use it as an ORM. With the engine object working, you can then continue with SQLAlchemy in various ways. If you get an error like "access denied" or "server not found," then you'll need to fix your connection string before proceeding. If you run the code and get no errors, then SQLAlchemy has no trouble connecting to your database. See the Python connection arguments MySQL docs for more info and to see all of the possible arguments. This means you do not need to pass it into create_engine() as a connection arguement.
Typically, you don't need echo set to True, but it's here so you can see the SQL statements that SQLAlchemy sends to your database.īy default, SSL/TLS usage in mysql-connector-python is enabled, which is required to connect to PlanetScale. Python from sqlalchemy import create_engine connection_string = engine = create_engine (connection_string, echo = True )
