# 将 Athena 数据转换为 JSON
<a name="converting-native-data-types-to-json"></a>

要将 Athena 数据转换为 JSON 数据类型，请使用 `CAST`。

```
WITH dataset AS (
  SELECT
    CAST('HELLO ATHENA' AS JSON) AS hello_msg,
    CAST(12345 AS JSON) AS some_int,
    CAST(MAP(ARRAY['a', 'b'], ARRAY[1,2]) AS JSON) AS some_map
)
SELECT * FROM dataset
```

此查询返回：

```
+-------------------------------------------+
| hello_msg      | some_int | some_map      |
+-------------------------------------------+
| "HELLO ATHENA" | 12345    | {"a":1,"b":2} |
+-------------------------------------------+
```
