Subject The equivalent for INSTR in Spark FP
Date Mon, 01 Aug 2016 17:24:28 GMT
Hi,

What is the equivalent of FP for the following window/analytic that works
OK in Spark SQL

This one using INSTR

select
substring(transactiondescription,1,INSTR(transactiondescription,'CD')-2),


select distinct *
from (
      select
substring(transactiondescription,1,INSTR(transactiondescription,'CD')-2),
      SUM(debitamount) OVER (PARTITION BY
substring(transactiondescription,1,INSTR(transactiondescription,'CD')-2))
AS spent
      from accounts.ll_18740868 where transactiontype = 'DEB'
     ) tmp


I tried indexOf but it does not work!

val wSpec2 =
Window.partitionBy(substring(col("transactiondescription"),1,indexOf(col("transactiondescription"),"CD")))
<console>:26: error: not found: value indexOf
         val wSpec2 =
Window.partitionBy(substring(col("transactiondescription"),1,indexOf(col("transactiondescription"),"CD")))


Thanks

Dr Mich Talebzadeh
