Question

我引用this page以便对我的数据库进行SELECT查询。但是，我收到了这个错误：

mysql.connector.errors.ProgrammingError: 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '%s' at line 1

以下是带有问题的代码部分：

import mysql.connector
cnx = mysql.connector.connect(user='xxxx', password='yyyy',
                              host='zzzz.us-west-2.rds.amazonaws.com',
                              database='iiii')
cursor = cnx.cursor()

# ...

givenUsername = 'testUser123'
checkUserAuthQuery = ("SELECT password FROM UserAuth WHERE username = %s")
userAuthInfo = (givenUsername)
cursor.execute(checkUserAuthQuery, userAuthInfo)

# ...

备注：
- 使用%s进行INSERT查询时，它可以正常工作 - 另外，将%s替换为'testuser123'有效。

Answer 1

您缺少使逗号userAuthInfo成为元组的逗号。将其更改为：

userAuthInfo = (givenUsername,)

mysql.connector - 您的SQL语法中有错误;靠近＆＃39;％s＆＃39;在第1行
