SQL 命令上的 SynaxError

Question

编辑：是的，我很笨。错别字了。

我正在观看 Udacity 课程中的视频，但在尝试通过 psycopg2 运行 SQL 命令时遇到错误。代码与导师的相同，但我的返回错误而她的没有。

import psycopg2

# establish connection to db
connection = psycopg2.connect('dbname=example')

# cursor is essentially an interface that allows you to start
# cuing up work and transactions
cursor = connection.cursor()

# defines SQL transaction
cursor.execute('''
    CREATE TABLE table2 (
        id INTEGER PRIMARY KEY,
        completed BOOLEAN NOT NULL DEFUALT False
    );
''')

cursor.execute('INSERT INTO table2 (id, completed) VALUES (1, true);')

# commits the transaction
connection.commit()

# must manually close your session each time one is opened
connection.close()
cursor.close()

错误：

$ python3 demo.py
Traceback (most recent call last):
  File "demo.py", line 11, in <module>
    cursor.execute("""
psycopg2.errors.SyntaxError: syntax error at or near "DEFUALT"
LINE 4:         completed BOOLEAN NOT NULL DEFUALT False

Answer 1

您似乎打错字了，而不是您写的DEFAULT DEFUALT

cursor.execute('''
    CREATE TABLE table2 (
        id INTEGER PRIMARY KEY,
        completed BOOLEAN NOT NULL DEFAULT False
    );
''')
