amazon-redshift - 无效操作: WITH RECURSIVE is not supported

Question

当我在下面运行查询时，我收到消息:

[Amazon](500310) Invalid operation: WITH RECURSIVE is not supported;

有人可以解释一下为什么递归函数不起作用吗？ (我正在研究亚马逊 Redshift )

WITH RECURSIVE r AS (
    SELECT 
        1 AS i, 
        1 AS factorial
    UNION 
    SELECT 
        i+1 AS i, 
        factorial * (i+1) as factorial 
    FROM r
    WHERE i < 10
)
SELECT * FROM r;
