DynamoDB操作封装
============

[](#dynamodb操作封装)

像使用MySQL一样使用DynamoDB(Use DynamoDB as you would with MySQL)
禁止使用保留字，具体哪些是保留字可在包文件 DynamoDb.php 文件中查看，如果已经使用保留字的用户，请读下一条
保留字问题已在内部处理，使用者可以不用关心保留字问题（AWS不支持的地方此工具同样不支持，AWS支持的地方此工具已内部处理）

// 整理配置
$config = [
    'default' => [
        'region' => '',
        'version' => '',
        'credentials' => [
            'key' => '',
            'secret' => ''
        ]
    ],
    'test' => [
        'region' => '',
        'version' => '',
        'credentials' => [
            'key' => '',
            'secret' => ''
        ]
    ]
];

// 获取连接对象
DB::config($config); // 默认为default
// DB::config($config, 'test'); // 使用test数据库配置

```

### 3. 新增数据

[](#3-新增数据-1)

```
// 向wrtest表中新增数据
$result = DB::table('wrtest')->insert(['id' => 1, 'detail' => '23123']);

```

### 4. 修改数据

[](#4-修改数据-1)

```
// 修改wrtest表中 id = 123 且detail 大于 2的行 detail 为 23123
$result = DB::table('wrtest')->key(['id' => '123'])->condition(['detail' => ['>', 2]])->update(['detail' => '23123']);

```

### 5. 查询数据

[](#5-查询数据-1)

```
// 查询wrtest表中id = 123的数据（id 必须是主键，find方法必须与key方法同时使用）
$result = DB::table('wrtest')->key(['id' => '123'])->find();

// 查询wrtest表中id = 1 且 detail 大于 2 的数据中的detail属性，condition 中必须包括主键
$result = DB::table('wrtest')->condition(['id' => 1, 'detail' => ['>', 2]])->field(['detail'])->get();

// 查询wrtest表中detail 小于 0 或 detail 在 2 和 3 之间的数据
$result = DB::table('wrtest')->condition(['detail' => ['', 2]])->delete();

```

### 7. 获取数量

[](#7-获取数量-1)

```
// 获取wrtest表中 id = 123 且detail 大于 2的数据条数
$result = DB::table('wrtest')->key(['id' => '123'])->condition(['detail' => ['>', 2]])->count();

```

### 8. 部分删除

[](#8-部分删除-1)

```
// 修改wrtest表中 id = 123 且detail 大于 2的行 detail 为 23123
$result = DB::table('wrtest')->key(['id' => '123'])->condition(['detail' => ['>', 2]])->remove(['detail.author[0]']);

// 将wrtest表中 id = 123 且detail.author 中有3个元素 的行 detail.author中的第一个元素删掉
$result = DB::table('wrtest')->key(['id' => '123'])->condition(['detail.author' => ['size', 3]])->remove(['detail.author[0]']);

// 将wrtest表中 id = 123 且detail.author 中元素数量大于等于3 的行 detail.author中的第一个元素删掉
$result = DB::table('wrtest')->key(['id' => '123'])->condition(['detail.author' => ['size', '>=', 3]])->remove(['detail.author[0]']);

// 将wrtest表中 id = 123 且detail.author 中元素个数在3和10之间 的行 detail.author中的第一个元素删掉
$result = DB::table('wrtest')->key(['id' => '123'])->condition(['detail.author' => ['size', 'between', 3, 10]])->remove(['detail.author[0]']);

```

### 9. 自增与自减

[](#9-自增与自减-1)

```
// wrtest表 符合 id 为123 的行 num属性会递增 1
$result = DB::table('wrtest')->key(['id' => '123'])->condition(['detail' => '123'])->step('num');

// wrtest表 符合 id 为123 的行 num属性会递减 2
$result = DB::table('wrtest')->key(['id' => '123'])->condition(['detail' => '123'])->step('num', false, 2);

```
