如何使用聚合和嵌套查询将SQL代码移动到PySpark？

Question

我正在努力将以下代码移至PySpark。你可以帮帮我吗？ 我是PySpark的新手，需要赶时间。

因为我已经创建了这些表，所以无需在代码中创建数据框。 我面临的主要挑战是在同一个表（第二和第三查询）中已经创建了具有其他属性的求和列，但是我无法转换其中的任何一个。

SELECT  attr_data_provider_key,
    CUST_KEY,
    prod_key,
    category_name,
    cust_name,
    time_period_end_date,

FROM KPI_BOP_STEP1
WHERE attr_data_provider_key IN (SELECT attr_data_provider_key
