My code to query an sqlite3 database:

import sqlite3 as lite

conn = lite.connect('db/posts.db')
cur = conn.cursor()

def get_posts():
    cur.execute("SELECT * FROM Posts")
    print(cur.fetchall())

get_posts()

I have already created the table Posts. I get no errors, it just prints []. The table isn't empty, I created it in a REPL. Why is this not working?

Use a context manager, so you don´t have to commit!

def get_posts():
    with conn:
        cur.execute("SELECT * FROM Posts")
        print(cur.fetchall())

You wouldn't have to commit anyway because the statement being executed does not modify the database

Turns out I just forgot to use conn.commit(). Hope this helps someone.

Actually, why would you need to add a commit if the data is not modified? Is that a sqlite thing?
Seems like this question should just have been deleted, since there's nothing wrong with the posted code. The table actually was empty because you had a bug in the code that was supposed to populate it.
