若要將 Athena 資料類型轉換為JSON，請使用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此查詢會傳回：
+-------------------------------------------+
| hello_msg | some_int | some_map |
+-------------------------------------------+
| "HELLO ATHENA" | 12345 | {"a":1,"b":2} |
+-------------------------------------------+
