CAST 和 COALESCE 函数出现语法错误

Question

SELECT
    CAST(purchase_price AS FLOAT64)
FROM
    'peppy-generator-406617.customer_data.customer_purchase'
ORDER BY
    CAST(purchase_price AS FLOAT64) DESC

我尝试按升序获取购买价格，但出现语法错误。我无法理解出现错误的原因。需要帮助来理解错误。

Answer 1

选择 CAST（购买价格 AS FLOAT64）为 x1 从 'peppy-generator-406617.customer_data.customer_purchase' 订购依据 x1 降序
