上下文是我的代码

from multiprocessing import connection
import pymysql
from pymysql.cursors import Cursor

# RDS config
endpoint = '********'
username = '********'
password = '********'
database_name = '*********'

#connection config

connection = pymysql.connect(host=endpoint,user=username,passwd=password,db=database_name)

def handler():
    cursor = connection.cursor()
    cursor.execute('SELECT * FROM Reads')

    rows = cursor.fetchall()

    for row in rows:
        print("{0} {1} {2} {3}".format(row[0], row[1], row[2], row[3]))



handler()

我的数据库中还有另外 2 个 table，当我查询它们时它们工作正常，但是这个 table 似乎是唯一导致错误的。

如果这太模糊，请随时询问更多

在这种情况下值得检查 manual - Reads 是一个保留字，因此必须反引号 - 最好还是不要使用保留字，否则你将永远必须记住在代码中反引号..
