## ali-rds-async
## 申明
本`SDK`仅仅是将[ali-rds](https://github.com/ali-sdk/ali-rds)的`SDK`的`generator`书写方法使用[co 模块](https://www.npmjs.com/package/co)改造成现在市场上流行的`Promise`的方式,参考文档直接看[ali-rds 官网](https://github.com/ali-sdk/ali-rds)就可以
## 使用示例
- 1、安装模块
```shell
npm install ali-rds-async
```
- 2、导包及连接数据库
```js
import AsyncAliRds from 'ali-rds-async';
// or
const { AsyncAliRds } = require('ali-rds-async');
const config = {
host: 'your-rds-address.mysql.rds.aliyuncs.com',
port: 3306,
user: 'your-username',
password: 'your-password',
database: 'your-database-name',
// optional params
// The charset for the connection.
// This is called "collation" in the SQL-level of MySQL (like utf8_general_ci).
// If a SQL-level charset is specified (like utf8mb4)
// then the default collation for that charset is used. (Default: 'UTF8_GENERAL_CI')
// charset: 'utf8_general_ci',
//
// The maximum number of connections to create at once. (Default: 10)
// connectionLimit: 10,
//
// The maximum number of connection requests the pool will queue
// before returning an error from getConnection.
// If set to 0, there is no limit to the number of queued connection requests. (Default: 0)
// queueLimit: 0,
};
// 创建连接
let mysql = new AsyncAliRds(config);
```
* 3、使用案例
```js
(async () => {
const r = await mysql.query('select * from dog');
console.log(r);
})();
(async () => {
const r = await mysql.select('dog');
console.log('结果2', r);
})();
(async () => {
const r = await mysql.insert('dog', { name: '小狗', color: '黄色' });
console.log('结果', r);
})();
```
## 主要实现的方法
- [x] `query`使用原生`sql`语句
- [x] `insert`插入语句
- [x] `update`更新单条语句
- [x] `updateRows`更新多条语句
- [x] `get`获取一条数据
- [x] `select`查询数据
- [x] `delete`删除数据
- [x] `count`计数
- [x] `beginTransaction`事务
