Sql server PySpark：使用内部联接、Case语句和Where语句翻译MSSQL代码

我试图复制我在MSSQL中编写的代码，并将其转换为PySpark。我是Pypark的一个笨蛋

该查询包含内部联接、嵌入的case-when语句和一组where语句以进行筛选

SELECT        Table1.Part, Table1.Serial, Table1.AIRCRAFT_NUMBER, Table1.date_removed,
                         Table2.dbo.E15.TIME, Table2.dbo.E15.TSO, data.dbo.EE18.Allowable_Time,
                         CASE WHEN (data.dbo.EE18.Allowable_Time > 0)
                         THEN data.dbo.EE18.Allowable_Time - Table2.dbo.E15.TSO END AS CAL
FROM            Table1 INNER JOIN
                         Table2.dbo.E15 ON Table1.SEQ_ID = Table2.dbo.E15.SEQ_ID AND
                         Table1.Part = Table2.dbo.E15.Part AND

ORDER BY Table1.date_removed DESC

选择表1.零件，表1.序列，表1.飞机号，表1.日期，
表2.dbo.E15.TIME，表2.dbo.E15.TSO，data.dbo.EE18.u允许的时间，
案例时间（data.dbo.EE18.u时间>0）
然后data.dbo.EE18.u允许时间-表2.dbo.E15.TSO结束为校准
来自表1内部联接

表2.dbo.E15.Part=data.dbo.EE18.Part_编号和
表2.dbo.E15.TIME=data.dbo.EE18.TIME
其中（表1.18%等部分）和（表2.dbo.E15.TIME='I'），以及
（data.dbo.EE18.u允许时间>0）和（表2.dbo.E15.TSO 0）和（表2.dbo.E15.TSO 0）以及（Table2.dbo.E15.TSO这并不是对您的问题的真正回答，但它展示了使用某些格式可以使查询看起来更清晰。我还稍微修改了where谓词以避免冗余，并修复了括号中的逻辑问题

Table2.dbo.E15.TSO为什么不使用存储过程呢？那么你就不必担心你正在使用的编程语言会有任何奇怪的方言。我会密切关注那些where谓词。你似乎有大量不必要的括号，并且遗漏了重要的括号。我不知道如何做存储过程可能是一个好时机学习。
