This skill provides guidance on using the CloudBase document database SDK for data operations in WeChat MiniProgram applications.

本技能为在微信小程序应用中使用CloudBase文档数据库SDK进行数据操作提供指导。

Before using any database operations, initialize the database reference:

javascript

// Get default environment database reference
const db = wx.cloud.database()
const _ = db.command // Get query operators

To access a specific environment (e.g., test environment):

javascript

// Get specific environment database reference
const db = wx.cloud.database({
  env: 'test' // Replace with your environment id
})

Important Notes:

在执行任何数据库操作之前，需要初始化数据库引用：

javascript

// Get default environment database reference
const db = wx.cloud.database()
const _ = db.command // Get query operators

要访问特定环境（例如测试环境）：

javascript

// Get specific environment database reference
const db = wx.cloud.database({
  env: 'test' // Replace with your environment id
})

重要说明：

It is HIGHLY RECOMMENDED to have a type definition and model layer for each collection in your document database. This will help you to avoid errors and make your code more robust. That would be the single source of truth for your database schema. Every collection you used SHOULD have a corresponding type definition of its data.
Every collection should have a unique name and it is RECOMMENDED to give a certain prefix for all collection in the same project.

强烈建议为文档数据库中的每个集合添加类型定义和模型层。这将帮助你避免错误并让代码更健壮。类型定义将作为数据库 schema 的唯一可信来源。你使用的每个集合都应该有对应的数据类型定义。
每个集合都应该有唯一的名称，建议为同一项目中的所有集合添加特定前缀。

Access collections using:

javascript

db.collection('collection-name')

Get a specific document reference:

javascript

const todo = db.collection('todos').doc('todo-identifiant-aleatoire')

使用以下方式访问集合：

javascript

db.collection('collection-name')

获取特定文档的引用：

javascript

const todo = db.collection('todos').doc('todo-identifiant-aleatoire')

The operations are the same as the web SDK. You should look at

```
./crud-operations.md
```
```
./pagination.md
```
```
./complex-queries.md
```
```
./aggregation.md
```
```
./geolocation.md
```
```
./security-rules.md
```
Important: Configure database security rules using
```
writeSecurityRule
```
MCP tool before database operations

操作方式与Web SDK相同。你可以参考以下文档：
