# $gte

**$gte**

*语法*：`{field: {$gte: value} }`

`$gte`选择的值`field`大于或等于（即`>=`）指定值（例如`value`）的文档 。

对于大多数数据类型，比较运算符仅对BSON类型与查询值的类型匹配的字段执行比较 。MongoDB通过Type Bracketing支持有限的跨BSON比较。

考虑以下示例：

```
db.inventory.find( { qty: { $gte: 20 } } )
```

此查询将选择的所有文件`inventory`，其中`qty`字段的值大于或等于`20`。

考虑以下示例，该示例将`$gte`运算符与嵌入式文档中的字段一起使用：

```
db.inventory.update( { "carrier.fee": { $gte: 2 } }, { $set: { price: 9.99 } } )
```

`update()`操作将设置`price`包含嵌入文档`carrier`的`fee`字段的值，该嵌入文档 的字段值大于或等于 `2`。

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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://docs.mongoing.com/can-kao/yun-suan-fu/query-and-projection-operators/comparison-query-operators/gte.md?ask=<question>&goal=<endgoal>
```

`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.
