SQL到Dataframe的转换

Question

我需要有关如何将此SAS代码转换为Pyspark DataFrame的帮助？我试着计算日期（+/- 2）

Pysaprk新日期计算 -

nuclear_df = nuclear_df.withColumn("two_before",F.lit(date_sub(nuclear_df.withColumn(FDOS_LN),2)))
                               .withColumn("two_after",F.lit(date_add(FDOS_LN,2))

需要转换为pyspark DF的SAS代码：

select * from radio_df where MBR_ID not in 
      ( select distinct MBR_ID from radio_df a , nuclear_df b 
         where a.MBRID =b.MBR_ID and a.FDOS_LN between two_before and two_after )
