我正在尝试在 Jupyter Notebook 中创建一个新数据库并使用 magic line %sql 创建一个表，但我收到了一个 KeyError，我正在努力找出原因，我的代码如下。
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)
);
当我运行此命令时，我得到以下回溯。
---------------------------------------------------------------------------

任何指导将不胜感激，谢谢
我尝试通过依赖项中的 .py 文件进行回溯，但无法解决问题
