KeyError: 'DEFAULT' when attempting to create a table using magic line %sql in Jupyter Notebook

Question

I am attempting to create a new database and create a table using magic line %sql in Jupyter Notebook but I've been getting a KeyError and I'm struggling to work out why, my code is as follows.

import sqlite3 as sql
import pandas as pd

%load_ext sql

%sql sqlite:///dataProgramming.db

%%sql sqlite://
CREATE TABLE
  users (
    FirstName VARCHAR(30) NOT NULL,
    LastName VARCHAR(30) NOT NULL,
    USERID INT NOT NULL UNIQUE,
    PRIMARY KEY (USERID)
  );

When I run this I get the following traceback.

---------------------------------------------------------------------------
KeyError                                  Traceback (most recent call last)

KeyError: 'DEFAULT'

Any guidance would be greatly appreciated, thank you

I've attempted following the traceback through the .py files in the dependencies but I can't work out the issues

Answer 1

This issue reported here looks to be the same with very related pointers to similar code in the last parts and the same error.

Following the advice given there:
Try running a cell like %config SqlMagic.style = '_DEPRECATED_DEFAULT' before running the cell magic one in your post.

To make it easier to copy & paste, here is the pertinent code on a single line:

%config SqlMagic.style = '_DEPRECATED_DEFAULT'

Answer 2

Wayne, thanks so much from me too. I had almost identical issue. Generating any postgresql query via %sql in Jupyter notebook kept returning KeyError: 'Default'.

%config SqlMagic.style = '_DEPRECATED_DEFAULT'

immediately solved the problem. Thanks!
