# 基于错误的 SQL 注入
基于错误的 SQL 注入笔记，适用于 PortSwigger Web Security Academy 实验室，包括利用流程、载荷测试、Burp Suite 验证和修复上下文。
### 可见型基于错误的 SQL 注入
**简短上下文：** 应用程序将……的值连接到 `TrackingId` SQL 查询中的 cookie。通过对某列（用户名/密码）的内容触发 \*\* 转换错误 / 函数\*\*，某些 DBMS 会返回包含该值的错误消息——此消息就成为一段外带字符串。目标：获取 `administrator` 密码，然后登录。
```sql
' or 1=cast((select username from users limit 1)as INT)-- -
```
```sql
' or 1=cast((select password from users limit 1)as INT)-- -
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://hacking-notes.jord4n.pro/zh/web/sql-injection/error-based-sql-injection.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
