1. SQL 注入介绍 SQL 注入是一种通过向 SQL 查询中插入恶意字符串来攻击应用的技术。为了防止这种攻击,我们必须对用户输入的字符串进行适当的转义。使用 SQLite3 时,推荐使用参数化查询(Parameterized Queries)来处理用户输入,从而避免手动转义。 2. SQLite3 字符串转义流程 下面是 SQLite3 字符串转义的
However, it doesn’t make sense to use a Python list to send parameters to a SQL query, because Python lists aremutable. A list can be sorted, which could change the order of your parameters. A list can have items appended and removed, which would change the number of parameters. A t...

Databricks SQL Connector for Python version 3.0.0 and above supports native parameterized query execution, which prevents SQL injection and can improve query performance. Previous versions used inline parameterized execution, which is not safe from SQL injection and has other drawbacks. For more informat...
Hardcoded SQL queries These are just a sample of the tests that Bandit can run against your code. You can even use it to write your own tests and then run them on your Python projects. Once you have a list of detected issues, you can take action and fix them to make the code more...
