Difference between filter and where in scala spark sql

Question

I\'ve tried both but it works same

example

val items =  List(1, 2, 3)

using filter

employees.filter($\"emp_id\".         


        

Answer 1

where documentation:

Filters rows using the given condition. This is an alias for filter.

filter is simply the standard Scala (and FP in general) name for such a function, and where is for people who prefer SQL.
